A health-check guide for an LLM-Wiki, where pages are stored as linked Markdown documents. It checks structure, source history, outdated claims, contradictions, missing ownership information, and taxonomy problems.

Use it to check broken and orphaned links, missing provenance, stale or conflicting claims, protected sections, and category drift. It can create reports and suggest changes, while applying fixes requires explicit permission.

It helps find damage or loss of trust after importing many pages, changing the structure, or before a large reorganisation. Findings become a review queue instead of being silently rewritten.

wiki-lint — Skill for Claude Code and Codex by po4yka/llm-wiki-skills

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.

Any agent

npx skills add po4yka/llm-wiki-skills --skill wiki-lint

Clone the repo

git clone --depth 1 https://github.com/po4yka/llm-wiki-skills

Made for: Claude Code, Codex.

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	$0.00047	$0.01107
Opus 5.5	$0.00019	$0.00443
Sonnet 5.5	$0.00009	$0.00221
Haiku 4.5	$0.00005	$0.00111

Security

Grade A, and why

wiki-lint 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/wiki-lint-core.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Wiki Lint

Goal

Detect structural decay, provenance gaps, stale claims and contradictions without silently rewriting truth.

When to use

The vault needs a structural or trust health check.
Before large refactors or after bulk ingestion.
A review queue should be generated from mechanical findings.

A filled final report ships in assets/worked-example.md.

Inputs

wiki/index.md
wiki/log.md
all wiki/**/*.md pages
_meta/taxonomy.md
_meta/schemas/*
optional git history

Write permissions

Allowed:

create reports under _agent/reports/;
append to wiki/log.md when a report is created;
propose patches;
fix trivial broken links only when the user explicitly asks for apply mode.

Not allowed by default:

resolve contradictions;
rewrite synthesis pages;
mark pages verified;
delete pages;
bulk-normalize frontmatter without a dry run.

Procedure

1. Run deterministic checks

node scripts/wiki-lint-core.mjs <vault-path>

The bundled script is read-only and prints a draft report covering the mechanical checks. Do not re-derive these by hand; re-run the script instead:

inventory: page counts by type/status, missing or malformed required frontmatter;
links: broken wikilinks and relative links, orphan pages, pages with no outbound links, duplicate titles, near-duplicate slugs;
provenance: generated or reviewed/verified factual pages without source_paths/source_urls, high-confidence pages with no source reference;
trust: ai_confidence < 0.70 without review_required: true, review_required: false on draft pages, verified pages past stale_after, ambiguous claim support outside review;
taxonomy: unknown types/statuses, tags missing from _meta/taxonomy.md, unused taxonomy tags.

Use --strict in CI to fail on critical/high findings.

2. Add judgement-only checks

The script cannot see these; check them manually:

pages changed since the last lint and pages without source backlinks in git history;
protected human sections changed by recent agent commits;
stale source hashes when available;
generated pages that cite only other generated pages;
pages missing from wiki/index.md that are likely important;
spelling-variant and overbroad tags beyond exact taxonomy mismatches.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

wiki-lint is a skill published in the GitHub repository po4yka/llm-wiki-skills (4 stars, last pushed 2d ago), licensed MIT. It adds 47 tokens to every session and 1,107 once invoked, about $0.0002 per session on Opus 5.5. 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.

Answer a question using ONLY the existing wiki vault as the knowledge base — no web search, no general LLM knowledge. Reads hot.md first (cheap recent context), then catalog.md to navigate, then drills into specific pages, then optionally semantic-searches the wiki, and synthesizes an answer with citations.
