second-brain-lint
Health-check the wiki for contradictions, orphan pages, stale claims, and missing cross-references. Use when the user says "audit", "health check", "lint", "find problems", or wants to improve wiki quality.
npx skills add NicholasSpisak/second-brain --skill second-brain-lint --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Second Brain — Lint Health-check the wiki and report issues with actionable fixes. ## Audit Steps Run all checks below, then present a consolidated report. ### 1. Broken wikilinks Scan all wiki pages for `[[wikilink]]` references. For each link, verify the target page exists. Report any broken links. ```bash # Find all wikilinks across wiki pages grep -roh '\[\[[^]]*\]\]' wiki/ | sort -u ``` Cross-reference against actual files in `wiki/`. ### 2. Orphan pages Find pages with no inbound links — no other page references them via `[[wikilink]]`. For each `.md` file in `wiki/sources/`, `wiki/entities/`, `wiki/concepts/`, `wiki/synthesis/`: - Extract the page name (filename without extension) - Search all other wiki pages for `[[Page Name]]` - If no other page links to it, it's an orphan ### 3. Contradictions Read pages that share entities or concepts and look for conflicting claims. Flag when: - Two source summaries make opposing claims about the same topic - An entity page contains information that conflicts with a source summary - Dates, figures, or factual claims differ between pages ### 4. Stale claims Cross-reference source dates with wiki content. Flag when: - A concept page ci

How do I install it?

Where does this skill come from?
From NicholasSpisak/second-brain, a repository with 652 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
