check

A command that checks a repository for new violations of its ArchSteer architecture rules. It compares the current code with a baseline, so older violations do not fail the check.

In plain words
What is it for?
Use it from the repository root or in CI after setting up an architecture configuration, then review and fix the newly introduced violations.
Why use it?
It lets existing technical debt remain while stopping the current change from adding more serious architecture problems. A failing result identifies the file, rule, and message to address.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

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 yesterday.

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

ArchSteer check

Run archsteer check in the repo root.

  • Requires .archsteer/architecture.yaml to exist (run archsteer init first if not — it auto-detects the stack and seeds a starter rule pack).
  • Only NET-NEW error-severity violations against the repo's baseline block (exit code 1); pre-existing debt never blocks. The output includes a conformance-score line (percent + delta since the last snapshot).

If it fails, list the net-new violations shown (file, rule, message) and fix the ones caused by the current change before finishing. If a violation looks like a genuine, repo-wide pattern shift rather than a one-off, suggest running archsteer adr instead of just patching around it.

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.

check is a command published in the GitHub repository einvoice-dev1/archsteer (5 stars, last pushed 1mo ago), licensed MIT. It adds 24 tokens to every session and 200 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
