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

# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project

Rune is a single-binary Rust application that is **three things in one**, chosen at runtime:

1. **Interactive / pipe CLI** — zero-trust AI agent (default invocation `rune` / `echo ... | rune`)
2. **Concourse CI resource type** — same binary, behavior selected by `argv[0]` (`check` / `in` / `out` symlinks)
3. **Notes web server** — `rune notes` starts an embedded Axum HTTP server with collaborative Markdown UI

`src/main.rs` dispatches all three modes (plus internal sandbox subcommands) before clap parses anything. When changing entry-point behavior, check the dispatch ladder in `main.rs` first — clap does not see those args.

## Build, Test, Lint

```bash
cargo build --release           # release binary (~4.3MB raw, ~1.6MB UPX; with notes ~8.4MB raw, ~4.0MB UPX)
./scripts/release.sh            # build & UPX-compress release binary
cargo test --all --no-fail-fast # unit tests
cargo fmt --all                 # required before every commit (CI enforces --check)
cargo clippy --all-targets -- -D warnings  # CI fails on any warning

How to install

The exact contents, by fingerprint
mdr add fourdollars/rune/CLAUDE.md@sha256:68cbd6118baf7822

The line at the top of this page pins the label git:20261004.82a726b, 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.
