Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00194 | $0.00759 |
| Opus 5 | $0.00097 | $0.00380 |
| Sonnet 5 | $0.00039 | $0.00152 |
| Haiku 4.5 | $0.00019 | $0.00076 |
Grade A, and why
knowledge-base-health-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 12d 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 — 38 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Knowledge Base Health Check Skill
This skill is the source of truth for the monthly knowledge base health check. The librarian reads it and follows it whenever a health check is invoked, on demand or via the scheduled task. The protocol is deliberately the same for both trigger paths so the output format is stable across runs.
When to invoke
Run this skill when any of the following happens: • The user says "run a health check", "audit the [name] KB", "check the wiki", or similar. or writes "/healthcheck" • The user says "action the latest health check" or "let's go through the health check report" - in that case, jump straight to Phase 2 using the most recent health-check report in the relevant KB's Outputs/ folder. • The monthly scheduled task fires it (taskld: knowledge-base-monthly-health-check ). If the user doesn't specify which KB, askl Don't run on every KB unless explicitly asked.
The two phases
The skill runs in two phases. Phase 1 always runs. Phase 2 runs only in interactive sessions - the scheduled task stops at the end of Phase 1.
Phase 1 — Audit and file (always)
- Read the rules. Open About me/writing-rules. md and the per-KB CLAUDE.md for the KB being audited. The writing rules govern the writing-rules check; the per-KB rules govern Wiki structure and source provenance.
- Read state files. /CHANGELOG.md (last health check date and what's happened since), /Wiki/QUESTIONS.md (already-flagged gaps so they aren't double-flagged), /RAW/_INGESTED. md (registry of what's in RAW).
- Read everything in scope. Every article in /Wiki/, every file in /RAW/ (at least the frontmatter and titles — full read only when verifying a specific claim), every output in /Outputs/ filed since the last health check.
- Run the seven audits. Detailed below.
- Write the full report to /Outputs/YYYY-MM-DD_health-check.md
- Append a one-line summary to /CHANGELOG.md at the top, format as in Logging below.
- Surface the chat summary. Print a tight summary into chat — counts only, plus the top three findings worth the user's attention, and a link to the full report. Do not dump the whole report.
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.

knowledge-base-health-check is a skill published in the GitHub repository julianobarbosa/claude-code-skills (10 stars, last pushed 16d ago), licensed MIT. It adds 194 tokens to every session and 759 once invoked, about $0.0010 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.
