check

A drift detector that compares a project's dossier, or written specification, with the current code and repository state. It reports violations and writes only rebuildable cache files.

In plain words
What is it for?
Use it to audit a dossier, check invariants, compare code with the specification, or verify a project before opening a pull request.
Why use it?
It shows when implementation no longer matches the documented requirements without changing the specification or source code.

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.

How it starts

The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ds:check — drift detector

Validates DOSSIER.md against reality and returns a severity-tagged violation list. It changes no DOSSIER.md content and no repo. Two derived paths are written: INDEX.md, which lib-ds-check.sh regenerates on every run (step 3), and .scratchpad/.verify-cache/, which verify_sweep.py populates at step 2a through verify_lib.cache_dir(). Both are caches rebuilt from source, never source themselves — the carve-out step 6 states.

Steps

0. Detect host env

Per ADAPTERS.md. Note Workflow tool presence (scout fan-out routing, §workflow).

1. Locate

Live dossier per ds:status step 1. --all adds archived dossiers as a sanity sweep.

2. Plan scout dispatch

One scout mission per §X repo, independent and parallel.

Mission template (per scout):

You are a dossier-scout. Read-only.

Dossier: <path-to-DOSSIER.md> (full file pasted below)
Repo to scan: <repo-path>

Headings are dual-spelled and the pasted file may use either. A ds:new
scaffold writes the plain names (`## Invariants`, `## Tasks`, `## Repos`);
older files write the sigils (`## §V`, `## §T`, `## §X`). The §-names below
are the section, not the literal heading — match whichever the file carries.

Tasks:
1. For each Invariants (§V) row with `check` = shell predicate: run the predicate, report PASS/FAIL.
2. For each Invariants (§V) row with `check` = test name: locate test in <repo-path>, run if executable, report PASS/FAIL/MISSING.
3. For each Tasks (§T) row with state=`x` + `cite=<sha>`: verify <sha> exists in <repo-path> git log. Report VALID/MISSING.
4. Refresh Repos (§X) for <repo>: git status -sb, ahead-count, latest tag, push state. Report current values; do NOT modify DOSSIER.md.

Output: caveman pipe-table. One row per finding.

<paste DOSSIER.md here>

Spawn one dossier-scout per repo, in parallel, via the Agent tool with subagent_type: dossier:dossier-scout.

§X repos > 2 and Workflow present → route the same missions through the §workflow fan-out (ADAPTERS.md): schema-validated rows, budget-gated width, crash-resumable. Otherwise the Agent spawns above.

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 skill published in the GitHub repository raisedadead/claude-code-plugins (2 stars, last pushed 6d ago), licensed ISC. It adds 59 tokens to every session and 2,069 once invoked, about $0.0003 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.
