description: Generates inline code comments and documentation strings. Use when writing function/class documentation, explaining complex logic, adding TODO/FIXME annotations, or documenting APIs in code.

Writing Code Comments and Docstrings

Quick start

Collect or infer:

  • •Programming language and documentation conventions
  • •Code element type (function, class, module, method)
  • •Target audience (internal team, external consumers, future maintainers)
  • •Complexity level of the code being documented
  • •Whether public API or internal implementation

Then produce output using TEMPLATES.md. Validate with RUBRIC.md.

Workflow

  1. •Identify documentation type: docstring (API), inline comment (implementation), or annotation (TODO/FIXME).
  2. •Determine what the code does vs. why it exists—document the latter.
  3. •For docstrings: document parameters, return values, exceptions, and side effects.
  4. •For inline comments: explain non-obvious decisions, constraints, or workarounds.
  5. •For annotations: include context, assignee (if known), and ticket reference.
  6. •Verify comments don't restate what code already says.
  7. •Run the rubric check. Revise until it passes.

Degrees of freedom

Medium freedom

  • •Default: follow language-specific conventions exactly
  • •Allowed variation: verbosity may adapt to code complexity; internal vs. external APIs may have different detail levels

State awareness

Code documentation serves different reader states:

  • •First encounter: What does this do? Should I use it?
  • •Integration: What parameters? What's returned? What can go wrong?
  • •Debugging: Why was this implemented this way?
  • •Maintenance: What's the history? What should I not change?
  • •Refactoring: What depends on this? What's the contract?
