design-check SKILL.md skillA

Removed from GitHub on 2026-11-09. The file no longer exists in its repository, and every version below is still saved here. mdr add no longer finds it by name, but a lockfile that pins one of these versions still installs it from its recorded commit, for as long as GitHub keeps that commit.

design-check from arcasilesgroup/ai-engineering is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Verify the implementation actually matches design.md — builds a requirement-by-requirement traceability table showing what is implemented, partial, missing, or contradicted, plus undocumented behavior the code added on its own. Use when asked to check code against the design/spec, confirm a feature was built as designed, find drift between design.md and the app, or answer "did we build what we said we would".

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

# Design conformance check

Verify the code against the design document. The deliverable is a **traceability
table**: every requirement in the spec mapped to the code that implements it, or
marked as missing. No requirement may be silently dropped.

Read `.claude/review/CONVENTIONS.md` first — stack detection, severity, the
false-positive gate, and the report format. The installed-version rule there
applies: never call an implementation wrong based on remembered framework
behavior.

## 1. Locate the spec

In order: a path given in the skill arguments → `design.md` at the repo root →
`docs/design.md`, `DESIGN.md`, `design/*.md`, `specs/*.md`, `docs/specs/*.md`,
`docs/rfcs/*.md`, an `adr/` directory, or a PRD directory the project documents
in its `README`/`CONTRIBUTING`. If the project has its own spec convention,
follow it over this list.

**If no design document exists, stop.** Do not invent requirements, and do not
substitute `README.md`, `CLAUDE.md`, or `AGENTS.md` — those describe setup and
agent rules, not intended behavior. Report:

> No design document found (looked at: `<paths>`). A conformance check needs a

How to install

The exact contents, by fingerprint

The line at the top of this page is already the fingerprint pin, because a file GitHub no longer serves cannot be found by its label. With it 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.
