   14:
```

**Multiple Definitions**:
```typescript
// Symbol defined in multiple places (overloads, re-exports)
find_definition("Logger")
// Returns all definitions
```

**Fuzzy Matching**:
If symbol not found, suggests similar symbols:
```
Symbol 'getUserByid' not found.

Did you mean?
  - getUserById (src/services/user.ts:45)
  - getUserByEmail (src/services/user.ts:67)
```

**Use Cases**:
- Jump to symbol definition
- Understand type signatures
- Find interface definitions

**Signature**:
```typescript
run_command(command: string, timeout?: number): ToolResult
```

**Parameters**:
- `command` (string, required): Shell command to execute
- `timeout` (number, optional): Timeout in milliseconds (max 600000). Default: 30000

**Security**:
1. **Blacklist Check**: Dangerous commands always blocked

        stdout: string
        stderr: string
        exitCode: number
        duration: number
    }
}
```

**Examples**:

```typescript
// Run build (whitelisted)
run_command("npm run build")
// Auto-approved, executes immediately

// Run tests (whitelisted)
run_command("npm test")

// Custom command (requires confirmation)
run_command("node scripts/migrate.js")
// User must approve

// With timeout
run_command("npm run build", 120000)  // 2 minutes
```

**Blacklisted Commands** (always blocked):
```
rm -rf
rm -r
sudo
git push --force
git reset --hard
git clean -fd
npm publish
chmod
chown
```

**Whitelisted Commands** (auto-approved):

tsc
vitest
jest
eslint
prettier
```

**Confirmation Dialog**:
```
┌─── Run Command ──────────────────────┐
│ Command: node scripts/migrate.js     │
│                                      │
│ This command is not whitelisted.     │
│ Do you want to allow it?             │
│                                      │
│ [Y] Allow  [N] Deny                  │

---

### run_tests

Run project tests with auto-detection of test runner.

**Signature**:
```typescript
run_tests(path?: string, filter?: string, watch?: boolean): ToolResult
```

**Parameters**:
- `path` (string, optional): Test file or directory. Default: all tests
- `filter` (string, optional): Test name pattern to match
- `watch` (boolean, optional): Run in watch mode. Default: false

**Test Runner Detection**:
1. Check for `vitest.config.ts` → use vitest
2. Check for `jest.config.js` → use jest
3. Check `package.json` devDependencies → vitest or jest
4. Check `package.json` scripts → npm test
5. Fallback: `npm test`

**Returns**:
```typescript
{
    success: true,
    output: {
        runner: "vitest" | "jest" | "mocha" | "npm"
        passed: boolean
        exitCode: number
        output: string
        stats?: {
            total: number
            passed: number
            failed: number
            skipped: number
        }
    }
}
```

**Examples**:

```typescript
// Run all tests
run_tests()
// Detects runner and executes

// Run specific test file
run_tests("tests/auth.test.ts")

// Run tests matching pattern
run_tests(null, "login")
// vitest: vitest -t "login"
// jest: jest --testNamePattern "login"

// Run in watch mode
run_tests(null, null, true)
// Background execution
```

**Example Output**:
```
Test runner: vitest
Running: vitest --run tests/auth.test.ts

 ✓ tests/auth.test.ts (5)
   ✓ login (3)
     ✓ should authenticate valid user
     ✓ should reject invalid password
     ✓ should handle missing user
   ✓ logout (2)
     ✓ should clear session
     ✓ should revoke token

Tests passed: 5/5
Duration: 234ms
```

**Use Cases**:
- Verify changes don't break tests
- Run specific test suites
- Check test coverage
- Continuous testing (watch mode)

**Error Cases**:
- No test runner detected
- Tests failed
- Invalid path
- Timeout

## Tool Confirmation

### Tools Requiring Confirmation

| Tool | When | Why |
|------|------|-----|
| `edit_lines` | Always | Modifies code |
| `create_file` | Always | Creates new file |
| `delete_file` | Always | Permanent deletion |
| `git_commit` | Always | Permanent action |
| `run_command` | Conditional | Unknown commands only |

### Confirmation Flow

```
1. Tool execution paused
2. ConfirmDialog shown to user
3. User chooses:
   - Apply/Yes: Continue execution
   - Cancel/No: Return error to LLM
   - Edit: Manual edit (future feature)
4. Result returned to LLM
5. LLM continues or adjusts based on result
```

### Auto-Apply Mode

Bypass confirmations with `--auto-apply`:

```bash
ipuaro --auto-apply
```

Or toggle in session:
```
/auto-apply on
```

**Warning**: Use with caution. The agent can make changes without approval.

## Error Handling

### Error Types

All tools return errors in standard format:

```typescript
{
    success: false,
    error: {
        type: "file" | "validation" | "parse" | "command" | "conflict" | "timeout",
        message: string,
        suggestion?: string,
        recoverable: boolean
    }
}
```

### Recoverable Errors

Errors the LLM can recover from:

- **File not found**: LLM can try different path
- **Parse error**: File has syntax errors, LLM can skip or fix
- **Validation error**: LLM can adjust parameters
- **Conflict**: File changed externally, LLM can regenerate
- **Command failed**: LLM can try alternative approach

### Non-Recoverable Errors

Errors that stop execution:

- **Redis unavailable**: Cannot continue without storage
- **Path outside project**: Security violation
- **Command blacklisted**: Security policy violation
- **Unknown error**: Unexpected failure

### Error Dialog

```
┌─── Error ────────────────────────────┐
│ Type: validation                     │
│ Message: Invalid line range 1-9999   │
│                                      │
│ Suggestion: Check file has 9999     │
│ lines. Use get_lines first.          │
│                                      │
│ [R] Retry  [S] Skip  [A] Abort       │
└──────────────────────────────────────┘

## Tool Tips

### Best Practices

1. **Read before edit**: Always use `get_lines` or `get_function` before `edit_lines`
2. **Check dependencies**: Use `get_dependents` before deleting files
3. **Verify impact**: Use `find_references` before refactoring functions
4. **Stage incrementally**: Commit related changes together
5. **Test after changes**: Use `run_tests` to verify changes don't break

### Common Patterns

**Refactoring Flow**:
```
1. find_references("oldFunction")
2. get_function("file.ts", "oldFunction")
3. edit_lines("file.ts", ...)  # Update implementation
4. For each reference:
   5. edit_lines(...)  # Update callers
6. run_tests()  # Verify
7. git_commit("refactor: update oldFunction")
```

**Bug Fix Flow**:
```
1. get_structure("src")  # Understand layout
2. find_definition("buggyFunction")
3. get_function("file.ts", "buggyFunction")
4. get_dependencies("file.ts")  # Check what it imports
5. edit_lines(...)  # Fix bug
6. run_tests("tests/bug.test.ts")
7. git_commit("fix: resolve issue #123")
```

**New Feature Flow**:
```
1. get_structure()  # Find where to add
2. create_file("src/new-feature.ts", ...)
3. edit_lines("src/index.ts", ...)  # Export new feature
4. create_file("tests/new-feature.test.ts", ...)
5. run_tests()
6. git_commit("feat: add new feature")
```
