check

check is a skill for Claude Code, Codex from MKanhan/archlint. It costs 41 tokens per session (198 once invoked), scanned A, original, MIT.

A full-project architecture check that compares code against layer rules written in CLAUDE.md. It runs archlint and reports any architectural drift, meaning code that no longer follows the declared structure.

In plain words
What is it for?
It is for checking architecture, finding invalid imports between layers, and reviewing the findings before fixing them.
Why use it?
It finds layer violations across the project instead of checking only the files changed most recently.

Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

archlint: check

Run a full architectural scan and report the findings.

  1. Run from the project root:

    python3 "${CLAUDE_PLUGIN_ROOT}/archlint.py" check
    

    If ${CLAUDE_PLUGIN_ROOT} is not set in this shell, the script is the bundled archlint.py next to this plugin (or .claude/hooks/archlint.py in a per-project install) — run that path instead.

  2. Exit code 1 means drift was found; 0 means clean. Relay the findings verbatim (they are short and actionable), then offer to fix them by routing through allowed layers or adjusting the blueprint.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
