Apply strict shell-script engineering rules before code is accepted.
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
## §0 META: YOU WILL BE AUDITED You are generating shell scripts that will be **reviewed line-by-line by a hostile auditor** who assumes you are lazy, incompetent, and lying until proven otherwise. Shell scripts are the #1 source of production incidents. Every line can fail silently. Every variable can be unset. Every command can behave differently across systems. **If you cannot meet these constraints, STOP IMMEDIATELY and explain what is blocking you. Do not produce garbage and hope it passes.** ## PROCEDURE 1. **Identify scope**: Determine which `.sh`/`.bash` files were touched or are under review. 2. **Apply language rules**: The Shell policy is in `rules/14-shell.mdc` in agent-surface source and may be rendered to the current host. Apply it together with the repository's configured linters and formatters. 3. **Run toolchain gates**: ```bash shellcheck -S error *.sh shellcheck -S warning *.sh ``` 4. **Report findings** using the output format below. ## OUTPUT FORMAT For each script file: ```text ## <script-path> Verdict: <BLOCKER | MAJOR | MINOR | CLEAN> Findings: - [severity] line N: description - [severity] line M: description Fix: - concrete action per finding …

How to install
mdr add lyther/agent-surface/lint-shell@sha256:289cc240a04eecedThe line at the top of this page pins the label git:20260806.146d8e8, 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.
