lean-comments

Audits, writes, and refines maintained first-party source-code comments and declaration-level documentation across languages. Use when adding, editing, reviewing, cleaning up, or auditing comments, doc comments, docstrings, TODO, FIXME, NOTE, suppressions, or other source commentary, including while modifying code and deciding whether a comment is warranted at all. Defaults to no comment unless it preserves meaningful, non-obvious information that cannot reasonably be recovered from the code or nearby repository context.

# Lean Comments

## Goal

Keep the smallest amount of high-value commentary necessary to make a codebase easier and safer to understand and maintain.

The default is **no comment**.

A comment must preserve meaningful information that a competent maintainer cannot reasonably recover from the code, names, types, signatures, structure, tests, configuration, or nearby context.

Comments are not labels, narration, decoration, declaration summaries, change logs, or substitutes for clear code.
