A maintenance command for a personal wiki: a collection of linked notes and source pages. It checks the wiki for disconnected pages, conflicting statements, outdated information, missing pages, broken links, and missing data.

Use it for regular wiki health checks, link maintenance, contradiction reviews, and finding pages or information that need attention.

It helps reveal problems that make a wiki harder to trust or navigate. Where possible, it fixes issues automatically and reports those that need a decision.

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.

Per session 62 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 625 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.

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	$0.00062	$0.00625
Opus 5	$0.00031	$0.00313
Sonnet 5	$0.00012	$0.00125
Haiku 4.5	$0.00006	$0.00063

Security

Grade A, and why

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

Lint

Runs the full lint workflow defined in CLAUDE.md. Checks for six categories of issues, fixes what can be fixed automatically, and reports the rest.

Workflow

Run all six checks. For each: identify issues, apply fixes where possible, and note anything that needs user input.

Check 1 — Orphan pages

Find wiki pages with no inbound [[links]] from any other wiki page
Glob wiki/*.md, read each, check whether any other page links to it
Fix: add links from relevant topic pages where appropriate
If a page is a stub with no clear home, flag it for the user to decide

Check 2 — Unresolved contradictions

Grep wiki/ for [!WARNING] Contradiction callouts
Report each one: which pages, what the conflict is, which sources are involved
Fix: flag to user with a recommendation — a new source may resolve it

Check 3 — Stale claims

Look for claims on older pages that newer source-summary pages have superseded
Cross-reference updated dates in frontmatter against source dates
Fix: update the claim and update the sources frontmatter attribution

Check 4 — Missing pages

Find [[wikilinks]] that appear frequently across wiki pages but have no corresponding file
Glob wiki/*.md, extract all [[...]] links, check each against the file system
Fix: create stub pages for high-frequency missing links and queue them for ingestion

Check 5 — Broken links

Find [[wikilinks]] pointing to files that don't exist
Fix: create the missing page as a stub, or correct the link if it's a typo

Check 6 — Data gaps

Identify important topics in the wiki that have many cross-references but thin source coverage
Look for topic pages with empty or sparse sources frontmatter
Report: suggest specific sources, articles, or web searches to fill each gap

Output

Produce a lint report with three sections:

Issues found — count and description per category
Fixes applied — what was changed automatically
Next sources to investigate — recommended reads to address data gaps or resolve contradictions

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.

lint is a skill published in the GitHub repository jessepinkman9900/claude-second-brain (47 stars, last pushed 4mo ago), licensed MIT. It adds 62 tokens to every session and 625 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.
