CocoLean diff-scoped over-engineering audit — scans uncommitted git diff and applies five classification tags (delete/stdlib/native/yagni/shrink) to identify unnecessary surface area before commit.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Objective You are executing `$lean review` — a diff-scoped over-engineering audit. Scan the uncommitted git diff and apply five CocoLean classification tags to each introduced construct. The audit is scoped to the current diff only — not the entire codebase. Feedback must be actionable at the moment of highest receptivity: before the commit. Before proceeding, verify that `.cocoplus/` exists. If not, output: "CocoPlus is not initialized. Run `$pod init` first." Then stop. ## Step 1 — Run Deterministic Diff Scanner ``` invoke cocolean/lean-review-engine ``` The script reads `git diff` (unstaged and staged changes), applies AST-level pattern matching, and outputs a JSON finding list. Read the JSON output. If no uncommitted changes exist, output: "No uncommitted changes found. `$lean review` operates on the current diff — stage or modify files first." Then stop. ## Step 2 — Classify Findings by Tag Apply the five CocoLean classification tags in severity order: **Tier 1 — Existence-level (surface first):** …

How to install
mdr add snowflake-labs/cocoplus/lean-review@sha256:79a585e511683b4dThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
