lean

v0.2.1

Claude writes the least code that solves the problem: reuse, standard library and platform before new code. What it skipped goes to a short plain-language line and, with session-board, to the board for your acceptance. Based on ponytail by Dietrich Gebert.

Included Skills3

leanskills/lean/SKILL.md

The lean rules and the switch between levels. Use when the user types /lean, asks for another lean level (lite, full, ultra), or asks to turn lean on or off.

lean-debtskills/lean-debt/SKILL.md

List every `lean:` shortcut comment in the codebase as one debt ledger, so a deliberate shortcut does not quietly become permanent. Use when the user asks "what did lean defer", "list the shortcuts", "lean debt", "what did we mark to do later", or types /lean-debt. A report; it changes nothing.

lean-reviewskills/lean-review/SKILL.md

Review for over-engineering only - what to delete, what the standard library or platform already does, abstractions with one user. A diff by default; the whole repository for an audit. Use when the user asks "is this over-engineered", "what can we delete", "review for bloat", "audit this repo for over-engineering", "find what to simplify", or types /lean-review. A report; it changes nothing.
