refactor(ipuaro): simplify LLM integration with pure XML tool format

Refactor OllamaClient to use pure XML format for tool calls as designed in CONCEPT.md. Removes dual system (Ollama native tools + XML parser) in favor of single source of truth (ResponseParser). Changes: - Remove tools parameter from ILLMClient.chat() interface - Remove convertTools(), convertParameters(), extractToolCalls() - Add XML format instructions to system prompt with examples - Add CDATA support in ResponseParser for multiline content - Add tool name validation with helpful error messages - Move ToolDef/ToolParameter to shared/types/tool-definitions.ts Benefits: - Simplified architecture (single source of truth) - CONCEPT.md compliance (pure XML as designed) - Better validation (early detection of invalid tools) - Reduced complexity (fewer format conversions) Tests: 1444 passed (+4 new tests) Coverage: 97.83% lines, 91.98% branches, 99.16% functions

 ## Project Overview
-Puaros is a TypeScript monorepo using pnpm workspaces. Currently contains the `@puaros/guardian` package - a code quality guardian for detecting hardcoded values, circular dependencies, framework leaks, naming violations, and architecture violations. The project uses Node.js 22.18.0 (see `.nvmrc`).
+Puaros is a TypeScript monorepo using pnpm workspaces. Contains two packages:
 - **`@samiyev/guardian`** - Code quality guardian for detecting hardcoded values, circular dependencies, framework leaks, naming violations, and architecture violations.
 - **`@samiyev/ipuaro`** - Local AI agent for codebase operations with "infinite" context feeling. Uses lazy loading, Redis persistence, tree-sitter AST parsing, and Ollama LLM integration.
 The project uses Node.js 22.18.0 (see `.nvmrc`).

-## Development Workflow
+## Monorepo Versioning Strategy
-### Complete Feature Development & Release Workflow
+### Git Tag Format
-This workflow ensures high quality and consistency from feature implementation to package publication.
+**Prefixed tags for each package:**
-
+```
-#### Phase 1: Feature Planning & Implementation
+guardian-v0.5.0
-
+ipuaro-v0.1.0
 ```bash
 # 1. Create feature branch (if needed)
 git checkout -b feature/your-feature-name
 # 2. Implement feature following Clean Architecture
 # - Add to appropriate layer (domain/application/infrastructure/cli)
 # - Follow naming conventions
 # - Keep functions small and focused
 # 3. Update constants if adding CLI options
 # Edit: packages/guardian/src/cli/constants.ts
 ```
-#### Phase 2: Quality Checks (Run After Implementation)
+**Why prefixed tags:**
 - Independent versioning per package
 - Clear release history for each package
 - Works with npm publish and CI/CD
 - Easy to filter: `git tag -l "guardian-*"`
 **Legacy tags:** Tags before monorepo (v0.1.0, v0.2.0, etc.) are kept as-is for historical reference.
 ### Semantic Versioning
 All packages follow SemVer: `MAJOR.MINOR.PATCH`
 - **MAJOR** (1.0.0) - Breaking API changes
 - **MINOR** (0.1.0) - New features, backwards compatible
 - **PATCH** (0.0.1) - Bug fixes, backwards compatible
 **Pre-1.0 policy:** Minor bumps (0.x.0) may include breaking changes.
 ## Release Pipeline
 **Quick reference:** Say "run pipeline for [package]" to execute full release flow.
 The pipeline has 6 phases. Each phase must pass before proceeding.
 ### Phase 1: Quality Gates
 ```bash
-# Navigate to package
+cd packages/<package>
 cd packages/guardian
-# 1. Format code (REQUIRED - 4 spaces indentation)
+# All must pass:
-pnpm format
+pnpm format                              # 4-space indentation
-
+pnpm build                               # TypeScript compiles
-# 2. Build to check compilation
+cd ../.. && pnpm eslint "packages/**/*.ts" --fix  # 0 errors, 0 warnings
-pnpm build
+cd packages/<package>
-
+pnpm test:run                            # All tests pass
-# 3. Run linter (must pass with 0 errors, 0 warnings)
+pnpm test:coverage                       # Coverage ≥80%
 cd ../.. && pnpm eslint "packages/**/*.ts" --fix
 # 4. Run tests (all must pass)
 pnpm test:run
 # 5. Check coverage (must be ≥80%)
 pnpm test:coverage
 ```
-**Quality Gates:**
+### Phase 2: Documentation
 - ✅ Format: No changes after `pnpm format`
 - ✅ Build: TypeScript compiles without errors
 - ✅ Lint: 0 errors, 0 warnings
 - ✅ Tests: All tests pass (292/292)
 - ✅ Coverage: ≥80% on all metrics
-#### Phase 3: Documentation Updates
+Update these files in `packages/<package>/`:
 | File | Action |
 |------|--------|
 | `README.md` | Add feature docs, update CLI usage, update API |
 | `TODO.md` | Mark completed tasks, add new tech debt if any |
 | `CHANGELOG.md` | Add version entry with all changes |
 | `ROADMAP.md` | Update if milestone completed |
 **Tech debt rule:** If implementation leaves known issues, shortcuts, or future improvements needed — add them to TODO.md before committing.
 ### Phase 3: Manual Testing
 ```bash
-# 1. Update README.md
+cd packages/<package>
 # - Add new feature to Features section
 # - Update CLI Usage examples if CLI changed
 # - Update API documentation if public API changed
 # - Update TypeScript interfaces
-# 2. Update TODO.md
+# Test CLI/API manually
-# - Mark completed tasks as done
+node dist/cli/index.js <command> ./examples
 # - Add new technical debt if discovered
 # - Document coverage issues for new files
 # - Update "Recent Updates" section with changes
-# 3. Update CHANGELOG.md (for releases)
+# Verify output, edge cases, error handling
 # - Add entry with version number
 # - List all changes (features, fixes, improvements)
 # - Follow Keep a Changelog format
 ```
-#### Phase 4: Verification & Testing
+### Phase 4: Commit
 ```bash
 # 1. Test CLI manually with examples
 cd packages/guardian
 node dist/cli/index.js check ./examples --limit 5
 # 2. Test new feature with different options
 node dist/cli/index.js check ./examples --only-critical
 node dist/cli/index.js check ./examples --min-severity high
 # 3. Verify output formatting and messages
 # - Check that all violations display correctly
 # - Verify severity labels and suggestions
 # - Test edge cases and error handling
 # 4. Run full quality check suite
 pnpm format && pnpm eslint "packages/**/*.ts" && pnpm build && pnpm test:run
 ```
 #### Phase 5: Commit & Version
 ```bash
 # 1. Stage changes
 git add .
 git commit -m "<type>(<package>): <description>"
-# 2. Commit with Conventional Commits format
+# Examples:
-git commit -m "feat: add --limit option for output control"
+# feat(guardian): add --limit option
-# or
+# fix(ipuaro): resolve memory leak in indexer
-git commit -m "fix: resolve unused variable in detector"
+# docs(guardian): update API examples
 # or
 git commit -m "docs: update README with new features"
 # Types: feat, fix, docs, style, refactor, test, chore
 # 3. Update package version (if releasing)
 cd packages/guardian
 npm version patch  # Bug fixes (0.5.2 → 0.5.3)
 npm version minor  # New features (0.5.2 → 0.6.0)
 npm version major  # Breaking changes (0.5.2 → 1.0.0)
 # 4. Push changes
 git push origin main  # or your branch
 git push --tags      # Push version tags
 ```
-#### Phase 6: Publication (Maintainers Only)
+**Commit types:** feat, fix, docs, style, refactor, test, chore
 ### Phase 5: Version & Tag
 ```bash
-# 1. Final verification before publish
+cd packages/<package>
-cd packages/guardian
+
 # Bump version
 npm version patch  # 0.5.2 → 0.5.3 (bug fix)
 npm version minor  # 0.5.2 → 0.6.0 (new feature)
 npm version major  # 0.5.2 → 1.0.0 (breaking change)
 # Create prefixed git tag
 git tag <package>-v<version>
 # Example: git tag guardian-v0.6.0
 # Push
 git push origin main
 git push origin <package>-v<version>
 ```
 ### Phase 6: Publish (Maintainers Only)
 ```bash
 cd packages/<package>
 # Final verification
 pnpm build && pnpm test:run && pnpm test:coverage
-# 2. Verify package contents
+# Check package contents
 npm pack --dry-run
-# 3. Publish to npm
+# Publish
 npm publish --access public
-# 4. Verify publication
+# Verify
-npm info @samiyev/guardian

-### Common Workflows
+## Working with Roadmap
 When the user points to `ROADMAP.md` or asks about the roadmap/next steps:
 1. **Read both files together:**
   - `packages/<package>/ROADMAP.md` - to understand the planned features and milestones
   - `packages/<package>/CHANGELOG.md` - to see what's already implemented
 2. **Determine current position:**
   - Check the latest version in CHANGELOG.md
   - Cross-reference with ROADMAP.md milestones
   - Identify which roadmap items are already completed (present in CHANGELOG)
 3. **Suggest next steps:**
   - Find the first uncompleted item in the current milestone
   - Or identify the next milestone if current one is complete
   - Present clear "start here" recommendation
 **Example workflow:**
 ```
 User: "Let's work on the roadmap" or points to ROADMAP.md
 Claude should:
 1. Read ROADMAP.md → See milestones v0.1.0, v0.2.0, v0.3.0...
 2. Read CHANGELOG.md → See latest release is v0.1.1
 3. Compare → v0.1.0 milestone complete, v0.2.0 in progress
 4. Report → "v0.1.0 is complete. For v0.2.0, next item is: <feature>"
 ```

 ## 11. Anemic Domain Model Detection
 ### Martin Fowler's Original Blog Post (2003)
 **Blog Post: "Anemic Domain Model"** (November 25, 2003)
 - Author: Martin Fowler
 - Published: November 25, 2003
 - Described as an anti-pattern related to domain driven design and application architecture
 - Basic symptom: domain objects have hardly any behavior, making them little more than bags of getters and setters
 - Reference: [Martin Fowler - Anemic Domain Model](https://martinfowler.com/bliki/AnemicDomainModel.html)
 **Key Problems Identified:**
 - "The basic symptom of an Anemic Domain Model is that at first blush it looks like the real thing"
 - "There are objects, many named after the nouns in the domain space, and these objects are connected with the rich relationships and structure that true domain models have"
 - "The catch comes when you look at the behavior, and you realize that there is hardly any behavior on these objects"
 - "This is contrary to the basic idea of object-oriented design; which is to combine data and process together"
 **Why It's an Anti-pattern:**
 - Fowler argues that anemic domain models incur all of the costs of a domain model, without yielding any of the benefits
 - The logic that should be in a domain object is domain logic - validations, calculations, business rules
 - Separating data from behavior violates core OOP principles
 - Reference: [Wikipedia - Anemic Domain Model](https://en.wikipedia.org/wiki/Anemic_domain_model)
 ### Rich Domain Model vs Transaction Script
 **Martin Fowler: Transaction Script Pattern**
 - Transaction Script organizes business logic by procedures where each procedure handles a single request
 - Good for simple logic with not-null checks and basic calculations
 - Reference: [Martin Fowler - Transaction Script](https://martinfowler.com/eaaCatalog/transactionScript.html)
 **When to Use Rich Domain Model:**
 - If you have complicated and everchanging business rules involving validation, calculations, and derivations
 - Object model handles complex domain logic better than procedural scripts
 - Reference: [InformIT - Domain Logic Patterns](https://www.informit.com/articles/article.aspx?p=1398617&seqNum=2)
 **Comparison:**
 - Transaction Script is better for simple logic
 - Domain Model is better when things get complicated with complex business rules
 - You can refactor from Transaction Script to Domain Model, but it's a harder change
 - Reference: [Medium - Transaction Script vs Domain Model](https://medium.com/@vibstudio_7040/transaction-script-active-record-and-domain-model-the-good-the-bad-and-the-ugly-c5b80a733305)
 ### Domain-Driven Design Context
 **Eric Evans: Domain-Driven Design** (2003)
 - Entities should have both identity and behavior
 - Rich domain models place business logic within domain entities
 - Anemic models violate DDD principles by separating data from behavior
 - Reference: Already covered in Section 10 - [Domain-Driven Design Book](#domain-driven-design)
 **Community Discussion:**
 - Some argue anemic models can follow SOLID design principles
 - However, consensus among DDD practitioners aligns with Fowler's anti-pattern view
 - Reference: [Stack Overflow - Anemic Domain Model Anti-Pattern](https://stackoverflow.com/questions/6293981/concrete-examples-on-why-the-anemic-domain-model-is-considered-an-anti-pattern)
 ---
 ## 12. Aggregate Boundary Validation (DDD Tactical Patterns)
 ### Eric Evans: Domain-Driven Design (2003)
 **Original Book Definition:**
 - Aggregate: "A cluster of associated objects that we treat as a unit for the purpose of data changes"
 - An aggregate defines a consistency boundary around one or more entities
 - Exactly one entity in an aggregate is the root
 - Reference: [Microsoft Learn - Tactical DDD](https://learn.microsoft.com/en-us/azure/architecture/microservices/model/tactical-ddd)
 **DDD Reference Document** (2015)
 - Official Domain-Driven Design Reference by Eric Evans
 - Contains comprehensive definitions of Aggregates and boundaries
 - Reference: [Domain Language - DDD Reference PDF](https://www.domainlanguage.com/wp-content/uploads/2016/05/DDD_Reference_2015-03.pdf)
 ### Vaughn Vernon: Implementing Domain-Driven Design (2013)
 **Chapter 10: Aggregates** (Page 347)
 - Author: Vaughn Vernon
 - Publisher: Addison-Wesley
 - ISBN: 978-0321834577
 - Available at: [Amazon - Implementing DDD](https://www.amazon.com/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577)
 **Key Rules from the Chapter:**
 - **Rule: Model True Invariants in Consistency Boundaries**
 - **Rule: Design Small Aggregates**
 - **Rule: Reference Other Aggregates by Identity**
 - **Rule: Use Eventual Consistency Outside the Boundary**
 **Effective Aggregate Design Series:**

 - Practical implementation guidance
 - Reference: Available in the book
 ### Tactical DDD Patterns
 **Microsoft Azure Architecture Center:**
 - "Using tactical DDD to design microservices"
 - Official Microsoft documentation on aggregate boundaries
 - Comprehensive guide for microservices architecture
 - Reference: [Microsoft Learn - Tactical DDD](https://learn.microsoft.com/en-us/azure/architecture/microservices/model/tactical-ddd)
 **SOCADK Design Practice Repository:**
 - Summaries of artifacts, templates, and techniques for tactical DDD
 - Practical examples of aggregate boundary enforcement
 - Reference: [SOCADK - Tactical DDD](https://socadk.github.io/design-practice-repository/activities/DPR-TacticDDD.html)
 ### Why Aggregate Boundaries Matter
 **Transactional Boundary:**
 - What makes it an aggregate is the transactional boundary
 - Changes to aggregate must be atomic
 - Ensures consistency within the boundary
 - Reference: [Medium - Mastering Aggregate Design](https://medium.com/ssense-tech/ddd-beyond-the-basics-mastering-aggregate-design-26591e218c8c)
 **Cross-Aggregate References:**
 - Aggregates should only reference other aggregates by ID, not direct entity references
 - Prevents tight coupling between aggregates
 - Maintains clear boundaries
 - Reference: [Lev Gorodinski - Two Sides of DDD](http://gorodinski.com/blog/2013/03/11/the-two-sides-of-domain-driven-design/)

 - Makes fixing the problem extremely difficult
 - Reference: [OWASP - Hardcoded Password Vulnerability](https://owasp.org/www-community/vulnerabilities/Use_of_hard-coded_password)
 ### Key Security Principles
 **Don't Hardcode Secrets:**
 - Secrets should not be hardcoded
 - Should not be unencrypted
 - Should not be stored in source code
 - Reference: [OWASP Secrets Management Cheat Sheet](https://cheatsheetseries.owasp.org/cheatsheets/Secrets_Management_Cheat_Sheet.html)
 **Centralized Management:**
 - Growing need to centralize storage, provisioning, auditing, rotation, and management of secrets
 - Control access and prevent secrets from leaking
 - Use purpose-built tools for encryption-at-rest
 - Reference: [OWASP SAMM - Secret Management](https://owaspsamm.org/model/implementation/secure-deployment/stream-b/)
 **Prevention Tools:**
 - Use pre-commit hooks to prevent secrets from entering codebase
 - Automated scanning in CI/CD pipelines
 - Reference: [GitHub OWASP Secrets Management](https://github.com/dominikdesmit/owasp-secrets-management)
 ### GitHub Secret Scanning

 ---
 ## 1. Executive Summary
 ### Key Finding
 **Industry consensus:** Automatic architecture detection is unreliable. All major tools (ArchUnit, eslint-plugin-boundaries, Nx, dependency-cruiser, SonarQube) require **explicit configuration** from users rather than attempting automatic detection.
 ### Why Automatic Detection Fails
 1. **Too Many Variations**: Project structures vary wildly across teams, frameworks, and domains
 2. **False Positives**: Algorithms may "detect" non-existent architectural patterns
 3. **Performance**: Graph analysis is slow for large codebases (>2000 files)
 4. **Ambiguity**: Same folder names can mean different things in different contexts
 5. **Legacy Code**: Poorly structured code produces meaningless analysis results
 ### Recommended Approach
 | Priority | Approach | Description |
 |----------|----------|-------------|
 | P0 | Pattern-based detection | Glob/regex patterns for layer identification |
 | P0 | Configuration file | `.guardianrc.json` for explicit rules |
 | P1 | Presets | Pre-configured patterns for common architectures |
 | P1 | Generic mode | Fallback with minimal checks |
 | P2 | Interactive setup | CLI wizard for configuration generation |
 | P2 | Graph visualization | Visual dependency analysis (informational only) |
 | ❌ | Auto-detection | NOT recommended as primary strategy |
 ---
 ## 2. Existing Tools Analysis
 ### 2.1 ArchUnit (Java)
 **Approach:** Fully declarative - user defines all layers explicitly.
 **Official Website:** https://www.archunit.org/
 **User Guide:** https://www.archunit.org/userguide/html/000_Index.html
 **GitHub Repository:** https://github.com/TNG/ArchUnit
 **Key Characteristics:**
 - Does NOT detect architecture automatically
 - User explicitly defines layers via package patterns
 - Fluent API for rule definition
 - Supports Layered, Onion, and Hexagonal architectures out-of-box
 - Integrates with JUnit/TestNG test frameworks
 **Example Configuration:**
 ```java
 layeredArchitecture()
    .layer("Controller").definedBy("..controller..")
    .layer("Service").definedBy("..service..")
    .layer("Persistence").definedBy("..persistence..")
    .whereLayer("Controller").mayNotBeAccessedByAnyLayer()
    .whereLayer("Service").mayOnlyBeAccessedByLayers("Controller")
    .whereLayer("Persistence").mayOnlyBeAccessedByLayers("Service")
 ```

 ## 3. Academic Approaches to Architecture Recovery
 ### 3.1 Software Architecture Recovery Overview
 **Wikipedia Definition:** https://en.wikipedia.org/wiki/Software_architecture_recovery
 Software architecture recovery is a set of methods for extracting architectural information from lower-level representations of a software system, such as source code. The abstraction process frequently involves clustering source code entities (files, classes, functions) into subsystems according to application-dependent or independent criteria.
 **Motivation:**
 - Legacy systems often lack architectural documentation
 - Existing documentation is frequently out of sync with implementation
 - Understanding architecture is essential for maintenance and evolution
 ---
 ### 3.2 Machine Learning Approaches
 **Research Paper:** "Automatic software architecture recovery: A machine learning approach"
 **Source:** ResearchGate - https://www.researchgate.net/publication/261309157_Automatic_software_architecture_recovery_A_machine_learning_approach
 **Key Points:**
 - Current architecture recovery techniques require heavy human intervention or fail to recover quality components
 - Machine learning techniques use multiple feature types:
  - Structural features (dependencies, coupling)
  - Runtime behavioral features
  - Domain/textual features
  - Contextual features (code authorship, line co-change)
 - Automatically recovering functional architecture facilitates developer understanding
 **Limitation:** Requires training data and may not generalize across project types.
 ---
 ### 3.3 Genetic Algorithms for Architecture Recovery
 **Research Paper:** "Parallelization of genetic algorithms for software architecture recovery"
 **Source:** Springer - https://link.springer.com/content/pdf/10.1007/s10515-024-00479-0.pdf
 **Key Points:**
 - Software Architecture Recovery (SAR) techniques analyze dependencies between modules
 - Automatically cluster modules to achieve high modularity
 - Many approaches employ Genetic Algorithms (GAs)
 - Major drawback: lack of scalability
 - Solution: parallel execution of GA subroutines
 **Finding:** Finding optimal software clustering is an NP-complete problem.
 ---
 ### 3.4 Clustering Algorithms Comparison
 **Research Paper:** "A comparative analysis of software architecture recovery techniques"
 **Source:** IEEE Xplore - https://ieeexplore.ieee.org/document/6693106/
 **Algorithms Compared:**
 | Algorithm | Description | Strengths | Weaknesses |
 |-----------|-------------|-----------|------------|
 | ACDC | Comprehension-Driven Clustering | Finds natural subsystems | Requires parameter tuning |
 | LIMBO | Information-Theoretic Clustering | Scalable | May miss domain patterns |
 | WCA | Weighted Combined Algorithm | Balances multiple factors | Complex configuration |
 | K-means | Baseline clustering | Simple, fast | Poor for code structure |
 **Key Finding:** Even the best techniques have surprisingly low accuracy when compared against verified ground truths.
 ---
 ### 3.5 ACDC Algorithm (Algorithm for Comprehension-Driven Clustering)
 **Original Paper:** "ACDC: An Algorithm for Comprehension-Driven Clustering"
 **Source:** ResearchGate - https://www.researchgate.net/publication/221200422_ACDC_An_Algorithm_for_Comprehension-Driven_Clustering
 **York University Wiki:** https://wiki.eecs.yorku.ca/project/cluster/protected:acdc
 **Algorithm Steps:**
 1. Build dependency graph
 2. Find "dominator" nodes (subsystem patterns)
 3. Group nodes with common dominators
 4. Apply orphan adoption for ungrouped nodes
 5. Iteratively improve clusters
 **Advantages:**
 - Considers human comprehension patterns
 - Finds natural subsystems
 - Works without prior knowledge
 **Disadvantages:**
 - Requires parameter tuning
 - Does not guarantee optimality
 - May not work well on poorly structured code
 ---
 ### 3.6 LLM-Based Architecture Recovery (Recent Research)
 **Research Paper:** "Automated Software Architecture Design Recovery from Source Code Using LLMs"
 **Source:** Springer - https://link.springer.com/chapter/10.1007/978-3-032-02138-0_5
 **Key Findings:**
 - LLMs show promise for automating software architecture recovery
 - Effective at identifying:
  - ✅ Architectural styles
  - ✅ Structural elements
  - ✅ Basic design patterns
 - Struggle with:
  - ❌ Complex abstractions
  - ❌ Class relationships
  - ❌ Fine-grained design patterns
 **Conclusion:** "LLMs can support SAR activities, particularly in identifying structural and stylistic elements, but they struggle with complex abstractions"

 ## 4. Graph Analysis Algorithms
 ### 4.1 Louvain Algorithm for Community Detection
 **Wikipedia:** https://en.wikipedia.org/wiki/Louvain_method
 **Original Paper:** "Fast unfolding of communities in large networks" (2008)
 - Authors: Vincent D Blondel, Jean-Loup Guillaume, Renaud Lambiotte, Etienne Lefebvre
 - Journal: Journal of Statistical Mechanics: Theory and Experiment
 - Reference: https://perso.uclouvain.be/vincent.blondel/research/louvain.html
 **Algorithm Description:**
 1. Initialize each node as its own community
 2. For each node, try moving to neighboring communities
 3. Select move with maximum modularity gain
 4. Merge communities into "super-nodes"
 5. Repeat from step 2
 **Modularity Formula:**
 ```
 Q = (1/2m) * Σ[Aij - (ki*kj)/(2m)] * δ(ci, cj)
 Where:
 - Aij = edge weight between i and j
 - ki, kj = node degrees
 - m = sum of all weights
 - δ = 1 if ci = cj (same cluster)
 ```
 **Characteristics:**
 | Parameter | Value |
 |-----------|-------|
 | Time Complexity | O(n log n) |
 | Modularity Range | -1 to 1 |
 | Good Result | Q > 0.3 |
 | Resolution Limit | Yes (may hide small communities) |
 **Implementations:**
 - NetworkX: https://networkx.org/documentation/stable/reference/algorithms/generated/networkx.algorithms.community.louvain.louvain_communities.html
 - Neo4j: https://neo4j.com/docs/graph-data-science/current/algorithms/louvain/
 - Graphology: https://graphology.github.io/standard-library/communities-louvain.html
 - igraph: https://igraph.org/r/doc/cluster_louvain.html
 **Application to Code Analysis:**
 ```
 Dependency Graph:
 User.ts → Email.ts, UserId.ts
 Order.ts → OrderId.ts, Money.ts
 UserController.ts → User.ts, CreateUser.ts
 Louvain detects communities:
 Community 1: [User.ts, Email.ts, UserId.ts]        // User aggregate
 Community 2: [Order.ts, OrderId.ts, Money.ts]      // Order aggregate
 Community 3: [UserController.ts, CreateUser.ts]   // User feature
 ```
 ---
 ### 4.2 Modularity as Quality Metric
 **Wikipedia:** https://en.wikipedia.org/wiki/Modularity_(networks)
 **Definition:** Modularity measures the strength of division of a network into modules (groups, clusters, communities). Networks with high modularity have dense connections within modules but sparse connections between modules.
 **Interpretation:**
 | Modularity Value | Interpretation |
 |------------------|----------------|
 | Q < 0 | Non-modular (worse than random) |
 | 0 < Q < 0.3 | Weak community structure |
 | 0.3 < Q < 0.5 | Moderate community structure |
 | Q > 0.5 | Strong community structure |
 | Q → 1 | Perfect modularity |

 ### 4.3 Graph-Based Software Modularization
 **Research Paper:** "A graph-based clustering algorithm for software systems modularization"
 **Source:** ScienceDirect - https://www.sciencedirect.com/science/article/abs/pii/S0950584920302147
 **Key Points:**
 - Clustering algorithms partition source code into manageable modules
 - Resulting decomposition is called software system structure
 - Due to NP-hardness, evolutionary approaches are commonly used
 - Objectives:
  - Minimize inter-cluster connections
  - Maximize intra-cluster connections
  - Maximize overall clustering quality
 ---
 ### 4.4 Topological Sorting for Layer Detection
 **Algorithm Description:**
 Layers can be inferred from dependency graph topology:
 - **Layer 0 (Domain)**: Nodes with no outgoing dependencies to other layers
 - **Layer 1 (Application)**: Nodes depending only on Layer 0
 - **Layer 2+ (Infrastructure)**: Nodes depending on lower layers
 **Pseudocode:**
 ```
 function detectLayers(graph):
    layers = Map()
    visited = Set()
    function dfs(node):
        if layers.has(node): return layers.get(node)
        if visited.has(node): return 0  // Cycle detected
        visited.add(node)
        deps = graph.getDependencies(node)
        if deps.isEmpty():
            layers.set(node, 0)  // Leaf node = Domain
            return 0
        maxDepth = max(deps.map(dfs))
        layers.set(node, maxDepth + 1)
        return maxDepth + 1
    graph.nodes.forEach(dfs)
    return layers
 ```
 **Limitation:** Assumes acyclic graph; circular dependencies break this approach.
 ---
 ### 4.5 Graph Metrics for Code Quality Assessment
 **Useful Metrics:**
 | Metric | Description | Good Value |
 |--------|-------------|------------|
 | Modularity | Clustering quality | > 0.3 |
 | Density | Edge/node ratio | Low for good separation |
 | Clustering Coefficient | Local clustering | Domain-dependent |
 | Cyclic Rate | % of circular deps | < 0.1 (10%) |
 | Average Path Length | Mean dependency distance | Lower = more coupled |
 **Code Quality Interpretation:**
 ```
 if cyclicRate > 0.5:
    return "SPAGHETTI"  // Cannot determine architecture
 if modularity < 0.2:
    return "MONOLITH"   // No clear separation
 if modularity > 0.5:
    return "WELL_STRUCTURED"  // Can determine layers
 return "MODERATE"
 ```

 ### 5.2 Architecture Drift Detection in CI/CD
 **Best Practices from Industry:**
 **Source:** Firefly Academy - https://www.firefly.ai/academy/implementing-continuous-drift-detection-in-ci-cd-pipelines-with-github-actions-workflow
 **Source:** Brainboard Blog - https://blog.brainboard.co/drift-detection-best-practices/
 **Key Recommendations:**
 1. **Integrate into Pipeline**: Validate architecture on every code update
 2. **Continuous Monitoring**: Run automated scans daily minimum, hourly for active projects
 3. **Enforce IaC-Only Changes**: All changes through automated workflows
 4. **Automated Reconciliation**: Regular drift detection and correction
 5. **Proper Alerting**: Slack for minor drift, PagerDuty for critical
 6. **Least Privilege**: Limit who can bypass architecture checks
 7. **Emergency Process**: Document process for urgent manual changes
 8. **Environment Refresh**: Reset after each pipeline run
 **Example GitHub Actions Integration:**
 ```yaml
 name: Architecture Check
 on: [push, pull_request]
 jobs:
    architecture:
        runs-on: ubuntu-latest
        steps:
            - uses: actions/checkout@v4
            - name: Check Architecture
              run: npx guardian check --strict
            - name: Generate Report
              if: failure()
              run: npx guardian report --format html
            - name: Upload Report
              if: failure()
              uses: actions/upload-artifact@v3
              with:

 ## 6. Industry Consensus
 ### 6.1 Why Major Tools Don't Auto-Detect
 | Tool | Auto-Detection | Reasoning |
 |------|----------------|-----------|
 | ArchUnit | ❌ No | "User knows their architecture best" |
 | eslint-plugin-boundaries | ❌ No | "Too many structure variations" |
 | Nx | ❌ No | "Tag-based approach is more flexible" |
 | dependency-cruiser | ❌ No | "Regex patterns cover all cases" |
 | SonarQube | ⚠️ Partial | "Basic analysis + config for accuracy" |
 ### 6.2 Common Themes Across Tools
 1. **Explicit Configuration**: All tools require user-defined rules
 2. **Pattern Matching**: Glob/regex patterns are universal
 3. **Layered Rules**: Allow/deny dependencies between layers
 4. **CI/CD Integration**: All support pipeline integration
 5. **Visualization**: Optional but valuable for understanding
 ### 6.3 Graph Analysis Position
 Graph analysis is used for:
 - ✅ Circular dependency detection
 - ✅ Visualization
 - ✅ Metrics calculation
 - ✅ Suggestion generation
 Graph analysis is NOT used for:
 - ❌ Primary layer detection
 - ❌ Automatic architecture classification
 - ❌ Rule enforcement

 ```
 ### 7.2 Implementation Priorities
 **Phase 1: Configuration File Support**
 - Add `.guardianrc.json` parser
 - Support custom layer patterns
 - Support custom DDD folder names
 - Validate configuration on load
 **Phase 2: Presets System**
 - Clean Architecture preset
 - Hexagonal Architecture preset
 - NestJS preset
 - Feature-based preset
 **Phase 3: Smart Defaults**
 - Try standard folder names first
 - Fall back to file naming patterns
 - Support common conventions
 **Phase 4: Interactive Setup**
 - `guardian init` command

 ### 7.3 Graph Analysis - Optional Feature Only
 Graph analysis should be:
 - **Optional**: Not required for basic functionality
 - **Informational**: For visualization and metrics
 - **Suggestive**: Can propose configuration, not enforce it
 **CLI Commands:**
 ```bash
 guardian analyze --graph --output deps.svg    # Visualization
 guardian metrics                               # Quality metrics
 guardian suggest                               # Configuration suggestions
 ```

 ## Conclusion
 The research conclusively shows that **automatic architecture detection is unreliable** and **not used by major industry tools**. The recommended approach for Guardian is:
 1. **Configuration-first**: Support explicit layer definitions via `.guardianrc.json`
 2. **Pattern-based**: Use glob/regex patterns for flexible matching
 3. **Presets**: Provide pre-configured patterns for common architectures
 4. **Smart defaults**: Try standard conventions when no config exists
 5. **Generic fallback**: Provide useful checks even without architecture knowledge
 6. **Graph analysis as optional**: Use for visualization and suggestions only
 This approach aligns with industry best practices from ArchUnit, eslint-plugin-boundaries, SonarQube, Nx, and dependency-cruiser.

 ## Anemic Domain Model Detection
 ### Why it matters
 Anemic domain models violate core OOP principles:
 - ❌ **No behavior** - Entities become data bags with only getters/setters
 - ❌ **Logic in services** - Business logic scattered across service layers
 - ❌ **Violates OOP** - Separates data from behavior
 - ❌ **Higher complexity** - Loses benefits of domain modeling
 ### Who says so?
 **Martin Fowler's Original Anti-Pattern:**
 - **Blog Post: "Anemic Domain Model"** (November 25, 2003)
  > "The basic symptom of an Anemic Domain Model is that at first blush it looks like the real thing. There are objects, many named after the nouns in the domain space... The catch comes when you look at the behavior, and you realize that there is hardly any behavior on these objects."
  - Published over 20 years ago, still relevant today
  - [Read Fowler's post](https://martinfowler.com/bliki/AnemicDomainModel.html)
 **Why It's an Anti-pattern:**
 > "This is contrary to the basic idea of object-oriented design; which is to combine data and process together."
 - Incurs all costs of domain model without any benefits
 - Logic should be in domain objects: validations, calculations, business rules
 - [Wikipedia - Anemic Domain Model](https://en.wikipedia.org/wiki/Anemic_domain_model)
 **Rich Domain Model vs Transaction Script:**
 - **Transaction Script**: Good for simple logic (Fowler, 2002)
 - **Rich Domain Model**: Better for complex, ever-changing business rules
 - Can refactor from Transaction Script to Domain Model, but it's harder than starting right
 - [Martin Fowler - Transaction Script](https://martinfowler.com/eaaCatalog/transactionScript.html)
 **Domain-Driven Design Context:**
 - **Eric Evans (2003)**: Entities should have both identity AND behavior
 - Anemic models violate DDD by separating data from behavior
 - [Stack Overflow discussion](https://stackoverflow.com/questions/6293981/concrete-examples-on-why-the-anemic-domain-model-is-considered-an-anti-pattern)

 ## Aggregate Boundary Validation
 ### Why it matters
 Proper aggregate boundaries ensure:
 - ✅ **Consistency** - Atomic changes within boundaries
 - ✅ **Low coupling** - Aggregates are loosely connected
 - ✅ **Clear transactions** - One aggregate = one transaction
 - ✅ **Maintainability** - Boundaries prevent complexity spread
 ### The Rules
 **Vaughn Vernon's Four Rules (2013):**
 1. **Model True Invariants in Consistency Boundaries**
 2. **Design Small Aggregates**
 3. **Reference Other Aggregates by Identity**
 4. **Use Eventual Consistency Outside the Boundary**
 ### Who says so?
 **Eric Evans: Domain-Driven Design (2003)**
 - **Original Definition**:
  > "A cluster of associated objects that we treat as a unit for the purpose of data changes"
 - An aggregate defines a consistency boundary
 - Exactly one entity is the aggregate root
 - [Microsoft Learn - Tactical DDD](https://learn.microsoft.com/en-us/azure/architecture/microservices/model/tactical-ddd)
 **Vaughn Vernon: Implementing Domain-Driven Design (2013)**
 - **Chapter 10: Aggregates** (Page 347)
 - ISBN: 978-0321834577
 - Comprehensive rules for aggregate design
 - Three-part essay series: "Effective Aggregate Design"
 - [Available at Kalele](https://kalele.io/effective-aggregate-design/)
 **Why Boundaries Matter:**
 - **Transactional Boundary**: Changes must be atomic
 - **Reference by ID**: No direct entity references across aggregates
 - **Prevents tight coupling**: Maintains clear boundaries

 ## Secret Detection
 ### Why it matters
 Hardcoded secrets create critical security risks:
 - 🔴 **Data breaches** - Exposed credentials lead to unauthorized access
 - 🔴 **Production incidents** - Leaked tokens cause service disruptions
 - 🔴 **Compliance violations** - GDPR, PCI-DSS, SOC 2 requirements
 - 🔴 **Impossible to rotate** - Secrets in code are difficult to change
 ### Who says so?
 **OWASP Security Standards:**
 - **OWASP Secrets Management Cheat Sheet**
  > "Secrets should not be hardcoded, should not be unencrypted, and should not be stored in source code."
  - Official best practices from OWASP Foundation
  - [Read the cheat sheet](https://cheatsheetseries.owasp.org/cheatsheets/Secrets_Management_Cheat_Sheet.html)
 - **OWASP Hardcoded Password Vulnerability**
  > "It is never a good idea to hardcode a password, as it allows all of the project's developers to view the password and makes fixing the problem extremely difficult."
  - [OWASP Documentation](https://owasp.org/www-community/vulnerabilities/Use_of_hard-coded_password)
 **GitHub Secret Scanning:**
 - **Official GitHub Documentation**
  - Automatically scans 350+ secret patterns
  - Detects AWS, GitHub, NPM, SSH, GCP, Slack tokens
  - AI-powered detection with Copilot Secret Scanning
  - [GitHub Docs](https://docs.github.com/code-security/secret-scanning/about-secret-scanning)
 **Key Security Principles:**
 - **Centralized Management**: Use purpose-built secret management tools
 - **Prevention Tools**: Pre-commit hooks to prevent secrets entering codebase
 - **Encryption at Rest**: Never store secrets in plaintext
 - [OWASP SAMM - Secret Management](https://owaspsamm.org/model/implementation/secure-deployment/stream-b/)
 **Mobile Security:**
 - OWASP: "Secrets security is the most important issue for mobile applications"
 - Only safe way: keep secrets off the client side entirely

 ## Severity-Based Prioritization
 ### Why it matters
 Severity classification enables:
 - ✅ **Focus on critical issues** - Fix what matters most first
 - ✅ **Reduced technical debt** - Prioritize based on impact
 - ✅ **Better CI/CD integration** - Fail builds on critical issues only
 - ✅ **Team efficiency** - Don't waste time on low-impact issues
 ### Who says so?
 **Academic Research:**
 - **Systematic Literature Review (2020)**
  - Title: "A systematic literature review on Technical Debt prioritization"
  - Analyzed 557 papers, included 44 primary studies
  - Finding: Need for consensus on severity factors
  - [ScienceDirect](https://www.sciencedirect.com/science/article/pii/S016412122030220X)
 - **IEEE Conference Paper (2021)**
  - "Technical Debt Prioritization: Taxonomy, Methods Results"
  - Reviewed 112 studies
  - Classified methods in 10 categories
  - [IEEE Xplore](https://ieeexplore.ieee.org/document/9582595/)
 - **Software Quality Journal (2023)**
  - "Identifying the severity of technical debt issues"
  - Problem: Most studies ignore severity degree
  - Proposed semantic + structural approach
  - [Springer](https://link.springer.com/article/10.1007/s11219-023-09651-3)
 **SonarQube Industry Standard:**
 - **Current Classification (10.2+)**:
  - **Blocker/High**: Severe unintended consequences, fix immediately
  - **Medium**: Impacts developer productivity
  - **Low**: Slight impact on productivity
  - **Info**: No expected impact
  - [SonarQube Docs](https://docs.sonarsource.com/sonarqube-server/user-guide/code-metrics/metrics-definition)
 **Real-World Impact:**
 - Development teams integrate models into CI/CD pipelines
 - Automatically flag potential TD issues during code reviews
 - Prioritize based on severity

 /**
- * Detects naming convention violations based on Clean Architecture layers
+ * Detects naming convention violations using AST-based analysis
 *
- * This detector ensures that files follow naming conventions appropriate to their layer:
+ * This detector uses Abstract Syntax Tree (AST) analysis via tree-sitter to identify
- * - Domain: Entities (nouns), Services (*Service), Value Objects, Repository interfaces (I*Repository)
+ * naming convention violations in classes, interfaces, functions, and variables
- * - Application: Use cases (verbs), DTOs (*Dto/*Request/*Response), Mappers (*Mapper)
+ * according to Clean Architecture layer rules.
- * - Infrastructure: Controllers (*Controller), Repository implementations (*Repository), Services (*Service/*Adapter)
+ *
 * The detector uses a modular architecture with specialized components:
 * - AstClassNameAnalyzer: Analyzes class names
 * - AstInterfaceNameAnalyzer: Analyzes interface names
 * - AstFunctionNameAnalyzer: Analyzes function and method names
 * - AstVariableNameAnalyzer: Analyzes variable and constant names
 * - AstNamingTraverser: Traverses the AST and coordinates analyzers
 *
 * @example
 * ```typescript
 * const detector = new NamingConventionDetector()
- * const violations = detector.detectViolations('UserDto.ts', 'domain', 'src/domain/UserDto.ts')
+ * const code = `
- * // Returns violation: DTOs should not be in domain layer
+ *     class userService {  // Wrong: should be UserService
 *         GetUser() {}     // Wrong: should be getUser
 *     }
 * `
 * const violations = detector.detectViolations(code, 'UserService.ts', 'domain', 'src/domain/UserService.ts')
 * // Returns array of NamingViolation objects

 # ipuaro Architecture
 This document describes the architecture, design decisions, and implementation details of ipuaro.
 ## Table of Contents
 - [Overview](#overview)
 - [Clean Architecture](#clean-architecture)
 - [Layer Details](#layer-details)
 - [Data Flow](#data-flow)
 - [Key Design Decisions](#key-design-decisions)
 - [Tech Stack](#tech-stack)
 - [Performance Considerations](#performance-considerations)
 ## Overview
 ipuaro is a local AI agent for codebase operations built on Clean Architecture principles. It enables "infinite" context feeling through lazy loading and AST-based code understanding.
 ### Core Concepts
 1. **Lazy Loading**: Load code on-demand via tools, not all at once
 2. **AST-Based Understanding**: Parse and index code structure for fast lookups
 3. **100% Local**: Ollama LLM + Redis storage, no cloud dependencies
 4. **Session Persistence**: Resume conversations across restarts
 5. **Tool-Based Interface**: LLM accesses code through 18 specialized tools
 ## Clean Architecture
 The project follows Clean Architecture with strict dependency rules:
 ```
 ┌─────────────────────────────────────────────────┐

 └─────────────────────────────────────────────────┘
 ```
 **Dependency Rule**: Outer layers depend on inner layers, never the reverse.
 ## Layer Details
 ### Domain Layer (Core Business Logic)
 **Location**: `src/domain/`
 **Responsibilities**:
 - Define business entities and value objects
 - Declare service interfaces (ports)
 - No external dependencies (pure TypeScript)
 **Components**:
 ```
 domain/
 ├── entities/
 │   ├── Session.ts           # Session entity with history and stats
 │   └── Project.ts           # Project entity with metadata
 ├── value-objects/
 │   ├── FileData.ts          # File content with hash and size
 │   ├── FileAST.ts           # Parsed AST structure
 │   ├── FileMeta.ts          # Complexity, dependencies, hub detection
 │   ├── ChatMessage.ts       # Message with role, content, tool calls
 │   ├── ToolCall.ts          # Tool invocation with parameters
 │   ├── ToolResult.ts        # Tool execution result
 │   └── UndoEntry.ts         # File change for undo stack
 ├── services/
 │   ├── IStorage.ts          # Storage interface (port)
 │   ├── ILLMClient.ts        # LLM interface (port)
 │   ├── ITool.ts             # Tool interface (port)
 │   └── IIndexer.ts          # Indexer interface (port)
 └── constants/
    └── index.ts             # Domain constants
 ```
 **Key Design**:
 - Value objects are immutable
 - Entities have identity and lifecycle
 - Interfaces define contracts, not implementations
 ### Application Layer (Use Cases)
 **Location**: `src/application/`
 **Responsibilities**:
 - Orchestrate domain logic
 - Implement use cases (application-specific business rules)
 - Define DTOs for data transfer
 - Coordinate between domain and infrastructure
 **Components**:
 ```
 application/
 ├── use-cases/
 │   ├── StartSession.ts      # Initialize or load session
 │   ├── HandleMessage.ts     # Main message orchestrator
 │   ├── IndexProject.ts      # Project indexing workflow
 │   ├── ExecuteTool.ts       # Tool execution with validation
 │   └── UndoChange.ts        # Revert file changes
 ├── dtos/
 │   ├── SessionDto.ts        # Session data transfer object
 │   ├── MessageDto.ts        # Message DTO
 │   └── ToolCallDto.ts       # Tool call DTO
 ├── mappers/
 │   └── SessionMapper.ts     # Domain ↔ DTO conversion
 └── interfaces/
    └── IToolRegistry.ts     # Tool registry interface
 ```
 **Key Use Cases**:
 1. **StartSession**: Creates new session or loads latest
 2. **HandleMessage**: Main flow (LLM → Tools → Response)
 3. **IndexProject**: Scan → Parse → Analyze → Store
 4. **UndoChange**: Restore file from undo stack
 ### Infrastructure Layer (External Implementations)
 **Location**: `src/infrastructure/`
 **Responsibilities**:
 - Implement domain interfaces
 - Handle external systems (Redis, Ollama, filesystem)
 - Provide concrete tool implementations
 - Security and validation
 **Components**:
 ```

 ├── indexer/
 │   ├── FileScanner.ts       # Recursive file scanning
 │   ├── ASTParser.ts         # tree-sitter parsing
 │   ├── MetaAnalyzer.ts      # Complexity and dependencies
 │   ├── IndexBuilder.ts      # Symbol index + deps graph
 │   └── Watchdog.ts          # File watching (chokidar)
 ├── tools/                   # 18 tool implementations
 │   ├── registry.ts
 │   ├── read/                # GetLines, GetFunction, GetClass, GetStructure
 │   ├── edit/                # EditLines, CreateFile, DeleteFile
 │   ├── search/              # FindReferences, FindDefinition
 │   ├── analysis/            # GetDependencies, GetDependents, GetComplexity, GetTodos
 │   ├── git/                 # GitStatus, GitDiff, GitCommit
 │   └── run/                 # RunCommand, RunTests
 └── security/
    ├── Blacklist.ts         # Dangerous commands
    ├── Whitelist.ts         # Safe commands
    └── PathValidator.ts     # Path traversal prevention
 ```
 **Key Implementations**:
 1. **RedisStorage**: Uses Redis hashes for files/AST/meta, lists for undo
 2. **OllamaClient**: HTTP API client with tool calling support

    ↓
 Commander.js parses arguments
    ↓
 Onboarding checks (Redis, Ollama, Model)
    ↓
 Initialize dependencies:
    - RedisClient connects
    - RedisStorage initialized
    - OllamaClient created
    - ToolRegistry with 18 tools
    ↓
 StartSession use case:
    - Load latest session or create new

    1. Add user message to history
    2. Build context (system prompt + structure + AST)
    3. Send to OllamaClient.chat()
    4. Parse tool calls from response
    5. For each tool call:
        - If requiresConfirmation: show ConfirmDialog
        - Execute tool via ToolRegistry
        - Collect results
    6. If tool results: goto step 3 (continue loop)
    7. Add assistant response to history
    8. Update session in Redis
    ↓
 Display response in Chat.tsx
 ```
 ### 3. Edit Flow
 ```
 LLM calls edit_lines tool
    ↓
 ToolRegistry.execute()
    ↓
 EditLinesTool.execute():
    1. Validate path (PathValidator)
    2. Check hash conflict
    3. Build diff
    ↓
 ConfirmDialog shows diff
    ↓
 User chooses:
    - Apply: Continue
    - Cancel: Return error to LLM
    - Edit: Manual edit (future)
    ↓
 If Apply:
    1. Create UndoEntry
    2. Push to undo stack (Redis list)
    3. Write to filesystem
    4. Update RedisStorage (lines, hash, AST, meta)
    ↓
 Return success to LLM
 ```
 ### 4. Indexing Flow
 ```
 FileScanner.scan()
    - Recursively walk directory
    - Filter via .gitignore + ignore patterns
    - Detect binary files (skip)
    ↓
 For each file:
    ASTParser.parse()
        - tree-sitter parse
        - Extract imports, exports, functions, classes
        ↓
    MetaAnalyzer.analyze()
        - Calculate complexity (LOC, nesting, cyclomatic)
        - Resolve dependencies (imports → file paths)
        - Detect hubs (>5 dependents)
        ↓
    RedisStorage.setFile(), .setAST(), .setMeta()
    ↓
 IndexBuilder.buildSymbolIndex()
    - Map symbol names → locations
    ↓
 IndexBuilder.buildDepsGraph()
    - Build bidirectional import graph
    ↓
 Store indexes in Redis
    ↓
 Watchdog.start()
    - Watch for file changes
    - On change: Re-parse and update indexes
 ```
 ## Key Design Decisions
 ### 1. Why Redis?
 **Pros**:
 - Fast in-memory access for frequent reads
 - AOF persistence (append-only file) for durability
 - Native support for hashes, lists, sets
 - Simple key-value model fits our needs
 - Excellent for session data
 **Alternatives considered**:
 - SQLite: Slower, overkill for our use case
 - JSON files: No concurrent access, slow for large data
 - PostgreSQL: Too heavy, we don't need relational features
 ### 2. Why tree-sitter?
 **Pros**:
 - Incremental parsing (fast re-parsing)
 - Error-tolerant (works with syntax errors)
 - Multi-language support
 - Used by GitHub, Neovim, Atom
 **Alternatives considered**:
 - TypeScript Compiler API: TS-only, not error-tolerant
 - Babel: JS-focused, heavy dependencies
 - Regex: Fragile, inaccurate
 ### 3. Why Ollama?
 **Pros**:
 - 100% local, no API keys
 - Easy installation (brew install ollama)
 - Good model selection (qwen2.5-coder, deepseek-coder)
 - Tool calling support
 **Alternatives considered**:
 - OpenAI: Costs money, sends code to cloud
 - Anthropic Claude: Same concerns as OpenAI
 - llama.cpp: Lower level, requires more setup
 Planned: Support for OpenAI/Anthropic in v1.2.0 as optional providers.
 ### 4. Why XML for Tool Calls?
 **Pros**:
 - LLMs trained on XML (very common format)
 - Self-describing (parameter names in tags)
 - Easy to parse with regex
 - More reliable than JSON for smaller models
 **Alternatives considered**:
 - JSON: Smaller models struggle with exact JSON syntax
 - Function calling API: Not all models support it
 ### 5. Why Clean Architecture?
 **Pros**:
 - Testability (domain has no external dependencies)
 - Flexibility (easy to swap Redis for SQLite)
 - Maintainability (clear separation of concerns)
 - Scalability (layers can evolve independently)
 **Cost**: More files and indirection, but worth it for long-term maintenance.
 ### 6. Why Lazy Loading Instead of RAG?
 **RAG (Retrieval Augmented Generation)**:
 - Pre-computes embeddings
 - Searches embeddings for relevant chunks
 - Adds chunks to context
 **Lazy Loading (our approach)**:
 - Agent requests specific code via tools
 - More precise control over what's loaded
 - Simpler implementation (no embeddings)
 - Works with any LLM (no embedding model needed)
 **Trade-off**: RAG might be better for semantic search ("find error handling code"), but tool-based approach gives agent explicit control.

 ## Performance Considerations
 ### 1. Indexing Performance
 **Problem**: Large projects (10k+ files) take time to index.
 **Optimizations**:
 - Incremental parsing with tree-sitter (only changed files)
 - Parallel parsing (planned for v1.1.0)
 - Ignore patterns (.gitignore, node_modules, dist)
 - Skip binary files early
 **Current**: ~1000 files/second on M1 Mac
 ### 2. Memory Usage
 **Problem**: Entire AST in memory could be 100s of MB.
 **Optimizations**:
 - Store ASTs in Redis (out of Node.js heap)
 - Load ASTs on-demand from Redis
 - Lazy-load file content (not stored in session)
 **Current**: ~200MB for 5000 files indexed
 ### 3. Context Window Management
 **Problem**: 128k token context window fills up.
 **Optimizations**:
 - Auto-compression at 80% usage
 - LLM summarizes old messages
 - Remove tool results older than 5 messages
 - Only load structure + metadata initially (~10k tokens)
 ### 4. Redis Performance
 **Problem**: Redis is single-threaded.
 **Optimizations**:
 - Pipeline commands where possible
 - Use hashes for related data (fewer keys)
 - AOF every second (not every command)
 - Keep undo stack limited (10 entries)
 **Current**: <1ms latency for most operations
 ### 5. Tool Execution
 **Problem**: Tool execution could block LLM.
 **Current**: Synchronous execution (simpler)
 **Future**: Async tool execution with progress callbacks (v1.1.0)
 ## Future Improvements
 ### v1.1.0 - Performance
 - Parallel AST parsing
 - Incremental indexing (only changed files)
 - Response caching
 - Stream LLM responses
 ### v1.2.0 - Features
 - Multiple file edits in one operation
 - Batch operations

 ## Programmatic API
 You can use ipuaro as a library in your own Node.js applications:
 ```typescript
 import {
    createRedisClient,
    RedisStorage,
    OllamaClient,
    ToolRegistry,
    StartSession,
    HandleMessage
 } from "@samiyev/ipuaro"
 // Initialize dependencies
 const redis = await createRedisClient({ host: "localhost", port: 6379 })
 const storage = new RedisStorage(redis, "my-project")
 const llm = new OllamaClient({
    model: "qwen2.5-coder:7b-instruct",
    contextWindow: 128000,
    temperature: 0.1
 })
 const tools = new ToolRegistry()
 // Register tools
 tools.register(new GetLinesTool(storage, "/path/to/project"))
 // ... register other tools
 // Start a session
 const startSession = new StartSession(storage)
 const session = await startSession.execute("my-project")
 // Handle a message
 const handleMessage = new HandleMessage(storage, llm, tools)
 await handleMessage.execute(session, "Show me the auth flow")
 // Session is automatically updated in Redis
 ```
 For full API documentation, see the TypeScript definitions in `src/` or explore the [source code](./src/).
 ## How It Works
 ### 1. Project Indexing
 When you start ipuaro, it scans your project and builds an index:
 ```
 1. File Scanner → Recursively scans files (.ts, .js, .tsx, .jsx)
 2. AST Parser → Parses with tree-sitter (extracts functions, classes, imports)
 3. Meta Analyzer → Calculates complexity, dependencies, hub detection
 4. Index Builder → Creates symbol index and dependency graph
 5. Redis Storage → Persists everything for instant startup next time
 6. Watchdog → Watches files for changes and updates index in background
 ```
 ### 2. Lazy Loading Context
 Instead of loading entire codebase into context:
 ```
 Traditional approach:
 ├── Load all files → 500k tokens → ❌ Exceeds context window
 ipuaro approach:
 ├── Load project structure → ~2k tokens
 ├── Load AST metadata → ~10k tokens
 ├── On demand: get_function("auth.ts", "login") → ~200 tokens
 ├── Total: ~12k tokens → ✅ Fits in 128k context window
 ```
 Context automatically compresses when usage exceeds 80% by summarizing old messages.
 ### 3. Tool-Based Code Access
 The LLM doesn't see your code initially. It only sees structure and metadata. When it needs code, it uses tools:
 ```
 You: "How does user creation work?"
 Agent reasoning:
 1. [get_structure src/] → sees user/ folder exists
 2. [get_function src/user/service.ts createUser] → loads specific function
 3. [find_references createUser] → finds all usages
 4. Synthesizes answer with only relevant code loaded
 Total tokens used: ~2k (vs loading entire src/ which could be 50k+)
 ```
 ### 4. Session Persistence
 Everything is saved to Redis:
 - Chat history and context state
 - Undo stack (last 10 file changes)
 - Session metadata and statistics
 Resume your session anytime with `/sessions load <id>`.
 ### 5. Security Model
 Three-layer security:
 1. **Blacklist**: Dangerous commands always blocked (rm -rf, sudo, etc.)
 2. **Whitelist**: Safe commands auto-approved (npm, git status, etc.)
 3. **Confirmation**: Unknown commands require user approval
 File operations are restricted to project directory only (path traversal prevention).
 ## Troubleshooting
 ### Redis Connection Errors
 **Error**: `Redis connection failed`
 **Solutions**:
 ```bash
 # Check if Redis is running
 redis-cli ping  # Should return "PONG"
 # Start Redis with AOF persistence
 redis-server --appendonly yes
 # Check Redis logs
 tail -f /usr/local/var/log/redis.log  # macOS
 ```
 ### Ollama Model Not Found
 **Error**: `Model qwen2.5-coder:7b-instruct not found`
 **Solutions**:
 ```bash
 # Pull the model
 ollama pull qwen2.5-coder:7b-instruct
 # List installed models
 ollama list
 # Check Ollama is running
 ollama serve
 ```
 ### Large Project Performance
 **Issue**: Indexing takes too long or uses too much memory
 **Solutions**:
 ```bash
 # Index only a subdirectory
 ipuaro ./src
 # Add more ignore patterns to .ipuaro.json
 {
    "project": {
        "ignorePatterns": ["node_modules", "dist", ".git", "coverage", "build"]
    }
 }
 # Increase Node.js memory limit
 NODE_OPTIONS="--max-old-space-size=4096" ipuaro
 ```
 ### Context Window Exceeded
 **Issue**: `Context window exceeded` errors
 **Solutions**:
 - Context auto-compresses at 80%, but you can manually `/clear` history
 - Use more targeted questions instead of asking about entire codebase
 - The agent will automatically use tools to load only what's needed
 ### File Changes Not Detected
 **Issue**: Made changes but agent doesn't see them
 **Solutions**:
 ```bash
 # Force reindex
 /reindex
 # Or restart with fresh index
 rm -rf ~/.ipuaro/cache
 ipuaro
 ```
 ### Undo Not Working
 **Issue**: `/undo` says no changes to undo
 **Explanation**: Undo stack only tracks the last 10 file edits made through ipuaro. Manual file edits outside ipuaro cannot be undone.
 ## FAQ
 **Q: Does ipuaro send my code to any external servers?**
 A: No. Everything runs locally. Ollama runs on your machine, Redis stores data locally, and no network requests are made except to your local Ollama instance.
 **Q: What languages are supported?**
 A: Currently TypeScript, JavaScript (including TSX/JSX). More languages planned for future versions.
 **Q: Can I use OpenAI/Anthropic/other LLM providers?**
 A: Currently only Ollama is supported. OpenAI/Anthropic support is planned for v1.2.0.
 **Q: How much disk space does Redis use?**
 A: Depends on project size. A typical mid-size project (1000 files) uses ~50-100MB. Redis uses AOF persistence, so data survives restarts.
 **Q: Can I use ipuaro in a CI/CD pipeline?**
 A: Yes, but it's designed for interactive use. For automated code analysis, consider the programmatic API.
 **Q: What's the difference between ipuaro and GitHub Copilot?**
 A: Copilot is an autocomplete tool. ipuaro is a conversational agent that can read, analyze, modify files, run commands, and has full codebase understanding through AST parsing.
 **Q: Why Redis instead of SQLite or JSON files?**
 A: Redis provides fast in-memory access, AOF persistence, and handles concurrent access well. The session model fits Redis's data structures perfectly.

 ```
 ### Example Queries
 Try these queries to explore ipuaro's capabilities:
 #### 1. Understanding the Codebase
 ```
 You: What is the structure of this project?
 ```
 ipuaro will use `get_structure` to show the directory tree.
 ```
 You: How does user creation work?
 ```
 ipuaro will:
 1. Use `get_structure` to find relevant files
 2. Use `get_function` to read the `createUser` function
 3. Use `find_references` to see where it's called
 4. Explain the flow
 #### 2. Finding Issues
 ```
 You: What TODOs and FIXMEs are in the codebase?
 ```
 ipuaro will use `get_todos` to list all TODO/FIXME comments.
 ```
 You: Which files are most complex?
 ```
 ipuaro will use `get_complexity` to analyze and rank files by complexity.
 #### 3. Understanding Dependencies
 ```
 You: What does the UserService depend on?
 ```
 ipuaro will use `get_dependencies` to show imported modules.
 ```
 You: What files use the validation utilities?
 ```
 ipuaro will use `get_dependents` to show files importing validation.ts.
 #### 4. Code Analysis
 ```
 You: Find all references to the ValidationError class
 ```
 ipuaro will use `find_references` to locate all usages.
 ```
 You: Where is the Logger class defined?
 ```
 ipuaro will use `find_definition` to locate the definition.
 #### 5. Making Changes
 ```
 You: Add a method to UserService to count total users
 ```
 ipuaro will:
 1. Read UserService class with `get_class`
 2. Generate the new method
 3. Use `edit_lines` to add it
 4. Show diff and ask for confirmation
 ```
 You: Fix the TODO in validation.ts about password validation
 ```
 ipuaro will:
 1. Find the TODO with `get_todos`
 2. Read the function with `get_function`
 3. Implement stronger password validation
 4. Use `edit_lines` to apply changes
 #### 6. Testing
 ```
 You: Run the tests
 ```
 ipuaro will use `run_tests` to execute the test suite.
 ```
 You: Add a test for the getUserByEmail method
 ```
 ipuaro will:
 1. Read existing tests with `get_lines`
 2. Generate new test following the pattern
 3. Use `edit_lines` to add it
 #### 7. Git Operations
 ```
 You: What files have I changed?
 ```
 ipuaro will use `git_status` to show modified files.
 ```
 You: Show me the diff for UserService
 ```
 ipuaro will use `git_diff` with the file path.
 ```
 You: Commit these changes with message "feat: add user count method"
 ```
 ipuaro will use `git_commit` after confirmation.
 ## Tool Demonstration Scenarios
 ### Scenario 1: Bug Fix Flow
 ```
 You: There's a bug - we need to sanitize user input before storing. Fix this in UserService.
 Agent will:
 1. get_function("src/services/user.ts", "createUser")
 2. See that sanitization is missing
 3. find_definition("sanitizeInput") to locate the utility
 4. edit_lines to add sanitization call
 5. run_tests to verify the fix
 ```
 ### Scenario 2: Refactoring Flow
 ```
 You: Extract the ID generation logic into a separate utility function
 Agent will:
 1. get_class("src/services/user.ts", "UserService")
 2. Find generateId private method
 3. create_file("src/utils/id.ts") with the utility
 4. edit_lines to replace private method with import
 5. find_references("generateId") to check no other usages
 6. run_tests to ensure nothing broke
 ```
 ### Scenario 3: Feature Addition
 ```
 You: Add password reset functionality to AuthService
 Agent will:
 1. get_class("src/auth/service.ts", "AuthService")
 2. get_dependencies to see what's available
 3. Design the resetPassword method
 4. edit_lines to add the method
 5. Suggest creating a test
 6. create_file("tests/auth.test.ts") if needed
 ```
 ### Scenario 4: Code Review
 ```
 You: Review the code for security issues
 Agent will:
 1. get_todos to find FIXME about XSS
 2. get_complexity to find complex functions
 3. get_function for suspicious functions
 4. Suggest improvements
 5. Optionally edit_lines to fix issues
 ```
 ## Slash Commands
 While exploring, you can use these commands:

 /undo               # Undo last file change
 /clear              # Clear chat history
 /reindex            # Force project reindexation
 /auto-apply on      # Enable auto-apply mode (skip confirmations)
 ```
 ## Hotkeys
 - `Ctrl+C` - Interrupt generation (1st) / Exit (2nd within 1s)
 - `Ctrl+D` - Exit and save session
 - `Ctrl+Z` - Undo last change
 - `↑` / `↓` - Navigate input history

 ## What ipuaro Can Do With This Project
 ### Read Tools ✅
 - **get_lines**: Read any file or specific line ranges
 - **get_function**: Extract specific functions (login, createUser, etc.)
 - **get_class**: Extract classes (UserService, AuthService, Logger, etc.)
 - **get_structure**: See directory tree
 ### Edit Tools ✅
 - **edit_lines**: Modify functions, fix bugs, add features
 - **create_file**: Add new utilities, tests, services
 - **delete_file**: Remove unused files
 ### Search Tools ✅
 - **find_references**: Find all usages of ValidationError, User, etc.
 - **find_definition**: Locate where Logger, UserService are defined
 ### Analysis Tools ✅
 - **get_dependencies**: See what UserService imports
 - **get_dependents**: See what imports validation.ts (multiple files!)
 - **get_complexity**: Identify complex functions (createUser has moderate complexity)
 - **get_todos**: Find 2 TODOs and 1 FIXME in the project
 ### Git Tools ✅
 - **git_status**: Check working tree
 - **git_diff**: See changes
 - **git_commit**: Commit with AI-generated messages
 ### Run Tools ✅
 - **run_command**: Execute npm scripts
 - **run_tests**: Run vitest tests
 ## Tips for Best Experience
 1. **Start Small**: Ask about structure first, then dive into specific files
 2. **Be Specific**: "Show me the createUser function" vs "How does this work?"
 3. **Use Tools Implicitly**: Just ask questions, let ipuaro choose the right tools
 4. **Review Changes**: Always review diffs before applying edits
 5. **Test Often**: Ask ipuaro to run tests after making changes
 6. **Commit Incrementally**: Use git_commit for each logical change
 ## Advanced Workflows
 ### Workflow 1: Add New Feature
 ```
 You: Add email verification to the authentication flow
 Agent will:
 1. Analyze current auth flow
 2. Propose design (new fields, methods)
 3. Edit AuthService to add verification
 4. Edit User types to add verified field
 5. Create tests for verification
 6. Run tests
 7. Offer to commit
 ```
 ### Workflow 2: Performance Optimization
 ```
 You: The user lookup is slow when we have many users. Optimize it.
 Agent will:
 1. Analyze UserService.getUserByEmail
 2. See it's using Array.find (O(n))
 3. Suggest adding an email index
 4. Edit to add private emailIndex: Map<string, User>
 5. Update createUser to populate index
 6. Update deleteUser to maintain index
 7. Run tests to verify
 ```
 ### Workflow 3: Security Audit
 ```
 You: Audit the code for security vulnerabilities
 Agent will:
 1. get_todos to find FIXME about XSS
 2. Review sanitizeInput implementation
 3. Check password validation strength
 4. Look for SQL injection risks (none here)
 5. Suggest improvements
 6. Optionally implement fixes
 ```
 ## Next Steps
 After exploring the demo project, try:
 1. **Your Own Project**: Run `ipuaro` in your real codebase
 2. **Customize Config**: Edit `.ipuaro.json` to fit your needs
 3. **Different Model**: Try `--model qwen2.5-coder:32b-instruct` for better results
 4. **Auto-Apply Mode**: Use `--auto-apply` for faster iterations (with caution!)
 ## Troubleshooting
 ### Redis Not Connected
 ```bash
 # Start Redis with persistence
 redis-server --appendonly yes
 ```
 ### Ollama Model Not Found
 ```bash
 # Pull the model
 ollama pull qwen2.5-coder:7b-instruct
 # Check it's installed
 ollama list
 ```
 ### Indexing Takes Long
 The project is small (~10 files) so indexing should be instant. For larger projects, use ignore patterns in `.ipuaro.json`.
