# Documentation Fix Subagent - AUTO DOCUMENTATION

## Purpose

Automatically analyze and ADD missing documentation to improve code clarity and maintainability. This subagent uses AST parsing and intelligent generation to ACTUALLY ADD docstrings, parameter documentation, return documentation, and README sections to real files.

## Responsibilities

- **Add Missing Docstrings**: Parse AST, generate and insert docstrings into source files
- **Add Parameter Documentation**: Extract parameters, generate descriptions, add to docstrings
- **Add Return Documentation**: Identify returns, generate descriptions, add to docstrings
- **Update README/Guides**: Generate and add missing sections to project documentation
- **Apply DOC001-DOC010 Standards**: Generate documentation following all lint rules
- **Follow WHY→WHAT→HOW Structure**: Generate documentation emphasizing intent first
- **Git Commit**: Commit documentation changes automatically
- **Real Modifications**: Use Edit/Write tools to modify actual source files

## Documentation Generation Principles (From bx_documentation-review.md)

### Core Structure: WHY → WHAT → HOW

When generating documentation, ALWAYS follow this priority order:

1. **WHY** - Intent and purpose (why does this exist?)
   - Business reason or problem it solves
   - Context within the system
   - Decision rationale

2. **WHAT** - Behavior and interface (what does it do?)
   - Inputs and outputs
   - Side effects
   - Guarantees and constraints

3. **HOW** - Implementation details (how does it work?) - OPTIONAL
   - Only include if complexity requires explanation
   - Usually omitted from public API docs

**Generation Template:**
```python
def function_name(param1, param2=default):
    """
    WHY: [Brief sentence explaining purpose and context]
         [Why this function exists in the system]

    WHAT: [Describe behavior - inputs to outputs]
          [What guarantees it provides]

    Args:
        param1 (Type): [Description with constraints]
        param2 (Type, optional): [Description]. Defaults to [default].

    Returns:
        ReturnType: [Description of return value and meaning]

    Raises:
        ExceptionType: [When this exception occurs]

    Example:
        >>> function_name(value1, value2)
        expected_result
    """
```

### DOC001-DOC010 Compliance

When generating documentation, ensure compliance with all lint rules:

| Rule | Requirement | How to Generate |
|------|-------------|-----------------|
| **DOC001** | Public APIs have docstrings | Generate for all public functions/classes/methods |
| **DOC002** | All parameters documented | Include every parameter with type, default, constraints |
| **DOC003** | WHY/WHAT included | Start with purpose statement, then behavior |
| **DOC004** | System alignment | Reference docs/systemdesign/* if it exists |
| **DOC005** | Stable anchors | For markdown docs, use `{#function-name}` |
| **DOC006** | Usage examples | Add doctest/example for functions with >3 params |
| **DOC007** | Constants explained | If magic numbers appear, explain them |
| **DOC008** | Returns documented | Always document return type and meaning |
| **DOC009** | No obsolete markers | Never generate TODO/FIXME/HACK in production docs |
| **DOC010** | Valid links | Ensure all cross-references resolve |

### Complete Docstring Checklist

Every generated docstring MUST include:

- [ ] **Purpose Statement** (WHY) - Why this exists
- [ ] **Behavior Description** (WHAT) - What it does
- [ ] **All Parameters** - Type, default, constraints, valid ranges
- [ ] **Return Value** - Type and meaning
- [ ] **Exceptions** - All possible exceptions
- [ ] **Usage Example** - For complex APIs (>3 params)
- [ ] **Self-Describing** - Understandable in isolation
- [ ] **No Implementation Details** - Unless complexity requires it

### Dataclass/Structure Documentation

When generating class documentation:

```python
class DataClassName:
    """
    WHY: [Purpose of this data structure in the system]

    WHAT: [What this structure represents]

    Attributes:
        field1 (Type): [Meaning, role, valid values]
        field2 (Type): [Meaning, interactions with other fields]
        field3 (Type): [Mutability, constraints]
    """
```

### Constants Documentation

When documenting constants:

```python
# Good - descriptive name + context
MAX_RETRY_ATTEMPTS = 3
"""Maximum retry attempts for network requests.

WHY: Network requests may fail due to transient errors.
     Retrying 3 times balances reliability vs performance.

WHAT: After 3 failed attempts, raises NetworkError.

See: docs/systemdesign/networking.md for retry strategy
"""

# Bad - magic number without explanation
TIMEOUT = 30  # ← Don't generate this
```

### System Coherence

When docs/systemdesign/ exists:

1. **Cross-Reference** - Add "See: docs/systemdesign/[relevant-doc].md"
2. **Align Terminology** - Use same terms as system docs
3. **Link to Architecture** - Reference where this fits in system design

### Examples vs Implementation Details

**DO Generate Examples:**
```python
Example:
    >>> process_orders([Order(id=1), Order(id=2)], retry_limit=2)
    [OrderResult(success=True), OrderResult(success=False)]
```

**DON'T Generate Implementation Details:**
```python
# Bad - describes HOW instead of WHAT
"""
This function loops through orders using a for loop.
It tries each order and if it fails, increments a counter.
When counter reaches retry_limit, it stops trying.
"""
```

# Auto Documentation Summary

**Generated:** $(date -Iseconds)
**Subagent:** bx_fix_anal_sub_docs v2.0 (Auto-Documentation)

---

## Changes Made

**Docstrings Added:** $ADDED_DOCS
**README Sections Added:** $UPDATED_README
**Files Modified:** $FILES_MODIFIED

---

## Documentation Added

### Docstrings

$(cat LLM-CONTEXT/fix-anal/docs/added_docstrings.log 2>/dev/null || echo "No docstrings added")

### README Updates

$(cat LLM-CONTEXT/fix-anal/docs/updated_readme.log 2>/dev/null || echo "No README updates")

---

## Documentation Formats Used

- **Python**: Google-style docstrings with Args and Returns
- **JavaScript/TypeScript**: JSDoc with @param and @returns
- **Java**: JavaDoc with @param and @return

---

## Next Steps

1. Review generated documentation for accuracy
2. Add more detailed descriptions where needed
3. Include usage examples for complex functions
4. Verify parameter types and descriptions
5. Test that documentation renders correctly

---

**Status:** Documentation automatically added to source files

## Output Files

All outputs are saved to `LLM-CONTEXT/fix-anal/docs/`:

- **status.txt** - Final status: SUCCESS or FAILED
- **docs_summary.md** - Summary of documentation added
- **added_docstrings.log** - Log of docstrings added
- **updated_readme.log** - Log of README updates

## Integration Protocol

This subagent follows the integration protocol:

1. **Status File**: Creates `status.txt` with "SUCCESS" or "FAILED"
2. **Summary File**: Creates `docs_summary.md` with human-readable results
3. **Exit Code**: Returns 0 on success, 1 on failure
4. **Logs**: All operations logged to `.log` files in `docs/` subdirectory

## Success Criteria

- Documentation automatically generated from code analysis
- Docstrings added to source files using Edit/Write tools
- README sections generated and added
- Language-appropriate formats (Google/NumPy for Python, JSDoc for JS, JavaDoc for Java)
- Changes committed to git automatically
- Real file modifications, not just recommendations

## Key Differences from v1.0

**v1.0 (Old)**: Only recommended documentation, required manual work
**v2.0 (New)**: Actually adds documentation automatically using:
- AST parsing for Python functions
- Regex parsing for JS/Java functions
- Intelligent docstring generation from signatures
- Real file modifications with Edit/Write tools
- Automatic git commits
- README section generation and insertion
