Before agreeing to build anything for a non-technical user, check the need against the consuming deployment's "## Stack map" section: in-stack needs proceed; out-of-stack or unmatched needs get a friendly, jargon-free decline plus an offer to file a well-formed issue on the block's owning repo (or the map's default intake repo). Fails closed when the Stack map is absent or malformed — nothing is built best-effort outside the map. Use in a vibe-coding setting whenever a build request is about…
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
# Allowed-stack guardrail
A deployment that lets people build conversationally still has a hard boundary: only the building
blocks the deployment actually operates are buildable. This skill is that boundary check. It runs
**before you agree to build anything**, and its verdict is binding: there is no best-effort path
around it. Declines are delivered in the register of the `jargon-free-voice` skill.
## The Stack map contract
The allowed stack is **deployment-owned configuration** — it never ships inside this skill. The
consuming deployment's canonical instructions file (`AGENTS.md`) defines it in a section titled
exactly **`## Stack map`**, containing:
- **A table** whose rows each carry three required fields:
- **Building block** — the block's plain-language name;
- **Good for** — the needs it serves, written in the user's vocabulary (this is the matching
surface);
- **Owning repo** — `owner/repo`, where a suggested issue for that block is filed.
- **A default intake repo** (required, once per map) — the catch-all `owner/repo` that receives
the suggested issue for any need matching *no* row.

How to install
mdr add devantler-tech/agent-plugins/allowed-stack-guardrail@sha256:441dcd44093994fbThe line at the top of this page pins the label git:20261101.7205f84, 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.
