What is knowledge-wiki-lint?

A health-check and repair tool for a knowledge wiki, a collection of linked notes and summaries. It checks for missing source documents, broken links, and concept files that are not connected to the rest of the wiki.

Run it periodically to check orphan summaries, broken wiki links, and orphan concept files. Use it after building up content or reorganizing the source files.

It finds cleanup problems that can appear after files are moved, deleted, or reorganized. It can remove summaries whose source documents no longer exist and repair other detected issues.

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	$0.00043	$0.03546
Opus 5.5	$0.00017	$0.01418
Sonnet 5.5	$0.00009	$0.00709
Haiku 4.5	$0.00004	$0.00355

Security

Grade A, and why

knowledge-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 2mo 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 — 379 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Knowledge Wiki Lint

Health-check and repair the wiki. Runs twelve checks in sequence — each builds on a clean state left by the previous one. JavaScript handles all file-system detection; the LLM handles any repair that requires judgment.

Setup

1. Establish the working directory

The knowledge base root is the Git repository root. Run git rev-parse --show-toplevel and store the result as KNOWLEDGE_PATH.

Use KNOWLEDGE_PATH for all subsequent steps.

Check 1 — Orphan Summaries

Deletes summary files whose source document has been moved or deleted.

2. Find orphan summaries

Run:

node {KNOWLEDGE_PATH}/scripts/wiki/wiki-lint.mjs find-orphan-summaries

Output is a JSON object keyed by orphan summary file path (relative to KNOWLEDGE_PATH). Each value has a source field with the path the summary expected to find, or null if the frontmatter had no source field.

If the object is empty ({}), skip to Check 2 and print Check 1: no orphan summaries.

3. Delete orphan summary files and remove their index entries

For each key in the output:

Delete the file at {KNOWLEDGE_PATH}/{key}.
Derive the summary's rel-path by stripping the Wiki/Summaries/ prefix and the .md extension from the key. Example: Wiki/Summaries/Posts/Foo.summary.md → Posts/Foo.summary. Then run:
```
node {KNOWLEDGE_PATH}/scripts/wiki/wiki-index.mjs delete-summary "{rel-path}"
```

After processing all orphans, delete any now-empty directories under Wiki/Summaries/:

find {KNOWLEDGE_PATH}/Wiki/Summaries -type d -empty -delete

Check 2 — Broken Summary → Concept Links

Creates missing concept files referenced by summaries.

4. Find and repair broken summary → concept links

Run:

node {KNOWLEDGE_PATH}/scripts/wiki/wiki-lint.mjs find-broken-summary-links

Output is a JSON object keyed by missing concept file path. Each value has a referencedBy array listing the summary files that link to that missing concept.

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.
