| name | wiki-lint |
| description | Health check on ~/brain/wiki/. Find orphan pages, broken cross-reference links, stale last_updated dates, missing frontmatter fields, concepts mentioned repeatedly without a dedicated page, and contradictions between pages. Use when the user says "/wiki-lint" or "lint the wiki." |
wiki-lint
Scan the wiki and report problems. Don't auto-fix — propose fixes and wait for confirmation.
Scope
- Directory:
~/brain/wiki/pages/
- Plus:
~/brain/wiki/index.md, overview.md, log.md
Checks
- Orphan pages — any page with zero inbound
[[slug]] references from other pages or from index.md.
- Broken links — any
[[slug]] that doesn't resolve to an existing page file.
- Missing frontmatter — every page must have
title, last_updated, tags, and at least one cross-reference in the body.
- Stale content — flag pages with
last_updated older than 90 days and suggest review.
- Undocumented concepts — tokens/phrases that appear 3+ times across pages without a dedicated page.
- Contradictions — conflicting facts between pages (dates, roles, numbers, URLs).
- Index drift — entries in
index.md that don't match page filenames, or pages not listed in index.md.
- Log hygiene — ensure
log.md entries are append-only (no modifications to prior dated sections) and parseable headers.
Output
Markdown report grouped by check:
# Wiki Lint Report — YYYY-MM-DD
## Orphan pages (N)
- slug — suggested fix
## Broken links (N)
- page.md → [[bad-slug]]
...
Append a log entry:
## [YYYY-MM-DD] lint | <one-line summary>
Issues found: <counts>
Notes: <top priorities>
Rules
- Report-only by default. Make no edits unless the user approves each fix.
- Never delete pages even when orphaned — suggest merging or adding cross-references instead.
