arch-check SKILL.md skillA

arch-check from swingerman/engineer is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add swingerman/engineer/arch-check@git:20261020.d56de69

Pins git:20261020.d56de69 in mdr.lock. Pin the fingerprint instead.

Use to check a feature's code against the charter's architecture rules — dependency layering, cycles, forbidden patterns, file naming, file size. Triggers — "/engineer.arch-check", "architecture check", "check architecture fitness", "does this follow the charter", "check layering".

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

# arch-check

Run the charter architecture fitness check — Checkpoint 7 (Light Verify),
alongside `crap-analyzer`. Turns the charter's architectural vision from prose
into an objective gate: `dae_arch.py` reads the manifest's `architecture:` rules
and reports violations.

Read-only on the codebase — it reports, it does not fix.

## When to use

Checkpoint 7, after the feature's code is implemented and refined. Also useful
as a standalone audit (`--full`) of an existing project.

**Not for:** change-risk analysis (`crap-analyzer`); artifact consistency
(`consistency-check`); fixing violations (that is a human/agent decision per
violation).

## Workflow

### Step 0 — Entry gate

Verify the prior checkpoint is complete: run
`${CLAUDE_PLUGIN_ROOT}/scripts/dae_handoff.py <feature-dir> --through 6`. On a
non-zero exit, **stop** and surface the gap to the human.

Verify branch hygiene: run `${CLAUDE_PLUGIN_ROOT}/scripts/dae_branch.py <feature-dir>`.
On a non-zero exit, **stop** and surface the message to the human — switch
branches and re-invoke. The check honors the `git.manual: true` manifest
opt-out.

After the gate passes, show the **pipeline breadcrumb**: run
…

How to install

The exact contents, by fingerprint
mdr add swingerman/engineer/arch-check@sha256:04d13e5cace9095c

The line at the top of this page pins the label git:20261020.d56de69, 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.
