AGENTS.md agentsA

AGENTS.md is agent-read markdown (agents) from lakeday-org/perch.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# perch

A semantic linter. tree-sitter parses the repository and builds a method-level call graph; a model is then asked a fixed set of
questions about each method, with its callers and callees in view. Answers come back as probabilities.

`src/` is the whole of it. `scan.yaml` is the questions perch ships with, in the same grammar `perch.yaml` takes.

## Before you open a pull request

```sh
npm run check     # lint, typecheck, test. This is what CI runs.
npm run build     # bundle src/cli.js into dist/cli.mjs
```

`npm run check` is the `build` job verbatim, so a green run here is a green run there. Run it before pushing, not after.

CI also runs `perch scan --since origin/main` on the branch. To see what it will say before you push:

```sh
npm run build && ./bin/perch.mjs scan --since origin/main
```

That costs real requests. `perch check <path>::<method>` asks about one method for a fraction of a cent, and reads the file off
disk rather than out of a commit, so it works on uncommitted code.

**A scan exits 3 when it found something and 1 when perch could not run.** 3 is a result. Only 1 and 2 are failures.

How to install

Latest version
mdr add lakeday-org/perch/AGENTS.md@git:20260920.aa3f08c
Exact content
mdr add lakeday-org/perch/AGENTS.md@sha256:20ebe6b97d1d85da

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
