wiki-lint

A wiki quality checker that scans pages for missing links, invalid metadata, old content, and conflicting claims. A wiki is a connected set of pages, and frontmatter is the metadata stored with a page.

In plain words
What is it for?
Finding orphan pages, broken or missing cross-references, missing required metadata, pages older than 90 days, and contradictions between pages.
Why use it?
It finds structural and content problems that are easy to miss when maintaining many linked pages.

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

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 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

wiki-lint

Scan the wiki for quality issues and report findings.

Checks performed

  1. Orphan pages: Pages with no inbound links from other pages
  2. Invalid frontmatter: Missing required fields (type, title, date, sources, tags, origin) — type is OKF-mandatory (ADR-045 §9.2)
  3. Missing cross-references: Broken wikilinks or missing bidirectional refs
  4. Stale pages: Pages not updated in over 90 days
  5. Contradictions: Conflicting claims across entity/concept pages

Severity levels

  • high: Invalid frontmatter, broken links, contradictions
  • medium: Orphan pages, missing bidirectional cross-references
  • low: Stale information, minor style issues
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.
