Use when writing a new pi-lens ast-grep rule YAML file — covers schema, drop path, gotchas, and NAPI runner constraints.
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
# Writing a pi-lens ast-grep Rule Drop path: `rules/ast-grep-rules/rules/<id>.yml` Same `id` as a built-in overrides it. Multiple rules per file: separate with `---`. ## Minimal template ```yaml id: no-foo-bar language: TypeScript # PascalCase — see languages below severity: warning # error | warning | hint | info — pick by evidence, see below message: "Avoid foo.bar() — use baz() instead" note: | Longer explanation / fix guidance here. rule: pattern: foo.bar($ARG) ``` **Pick the severity by the evidence behind the rule, not by feel:** - **`error`** — only with a documented zero-false-positive audit in the `note`. Only `error` maps to semantic `blocking` and stops a turn. - **`warning`** — a real finding with a known, bounded false-positive rate. - **`hint` / `info`** — style opinions. They render as advisory text, never block, and lose the report budget to warnings when a report is capped. Full policy and the `error`-promotion procedure: AGENTS.md's "Severity policy (#1777)" section. Read it before shipping anything above `warning`. ## Before promoting to error Three things must all be true, and the rule's `note` must record them: …

How to install
mdr add apmantza/pi-lens/pi-lens-write-ast-grep-rule@sha256:c956ef2439247bfcThe line at the top of this page pins the label git:20260820.13d056f, 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.
