A read-only health audit for a knowledge vault, using schema.md as its rulebook. It checks the vault's files, links, indexes, freshness, and generated sections for differences from that contract.

Auditing vault health, listing suggested fixes, rebuilding the index, or applying limited mechanical fixes.

It reveals broken, outdated, missing, or inconsistent vault content without changing it by default.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00064	$0.02337
Opus 5	$0.00032	$0.01169
Sonnet 5	$0.00013	$0.00467
Haiku 4.5	$0.00006	$0.00234

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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/check — Vault Health Audit

Philosophy

/check treats schema.md as the contract and wiki/ as the implementation. Its job is to surface every place the implementation diverges from the contract — so the user (or /taste / /ingest re-runs) can reconcile.

/check is read-only. It never auto-fixes. Each finding comes with a suggested next step.

Invocation

/check                     # full audit
/check --aesthetics        # only aesthetics/_panels/_prompts
/check --stale             # only freshness / AAT 14-day grace / prompt 30-day
/check --fix-safe          # apply ONLY the fixes where no human judgment is required
/check --rebuild-index     # full scan, rewrite wiki/index.md from wiki/ state
/check --migrate           # additive schema bump (e.g. 1.3 → 1.4 → 2.1) — adds null fields, never rewrites content

--fix-safe is the single exception to read-only — and it applies only to mechanical rebuilds (edges.jsonl, wikilink regeneration), never to content.

Check categories

Category 1 — Schema conformance

Read schema.md to get current schema_version. For every MD under wiki/:

Frontmatter has all required fields for its type: — per schema.md §4
schema_version in the MD matches or is ≤ current (missing → flag for migration)
Frontmatter YAML parses — malformed YAML is a hard error

Category 2 — Aesthetic-specific

For every type: aesthetic:

aat_id resolved OR aat_uncertainty present (past 14-day grace window = surface)
wikidata resolved OR wikidata_uncertainty present (same grace policy)
panofsky_layer declared
Body contains  ...  markers
Body contains  ... markers
Each modality in prompts: frontmatter block has at least a generated: date
warburg_panel wikilinks resolve to existing panel MDs

Category 3 — Prompt freshness

For every type: aesthetic with prompts.<modality>.last_tested:

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 P1-103n1x/bab-ilu (11 stars, last pushed 4mo ago), licensed MIT. It adds 64 tokens to every session and 2,337 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 2026-08-30.
