Health-check the wiki for missing articles, stale content, broken backlinks, and cross-reference gaps.

Run this after any session where new session logs were created, or when starting a new session and the wiki may be out of date. Also run before any `/wiki-compile all` pass.

---

## Step 1 — Missing Articles (Primary Check)

Scan for clients and projects that have session logs but no wiki article.

```bash
# List all client slugs that have session-logs but no wiki article
cd D:/claudetools
for dir in clients/*/session-logs; do
  slug=$(echo "$dir" | sed 's|clients/||;s|/session-logs||')
  wiki="wiki/clients/$slug.md"
  if [ ! -f "$wiki" ]; then
    count=$(ls "$dir"/*.md 2>/dev/null | wc -l)
    echo "MISSING: $wiki  ($count session logs)"
  fi
done
```

```bash
# List all project slugs that have session-logs but no wiki article
for dir in projects/*/session-logs; do
  slug=$(echo "$dir" | sed 's|projects/||;s|/session-logs||')
  wiki="wiki/projects/$slug.md"
  if [ ! -f "$wiki" ]; then
    count=$(ls "$dir"/*.md 2>/dev/null | wc -l)
    echo "MISSING: $wiki  ($count session logs)"
  fi
done
```

Report each missing article as:
```
[MISSING] wiki/clients/<slug>.md — <N> session logs, oldest: <YYYY-MM-DD>
```

Suggest: `Run /wiki-compile client:<slug> to seed.`

---

## Step 2 — Stale Articles

Check `last_compiled` date in all wiki article frontmatter. Flag any article where:
- `last_compiled` is more than 90 days ago AND there are session logs newer than `last_compiled`
- Report as `[STALE]` with days since compile and count of new logs

Use `grep -r "last_compiled:" wiki/` to collect dates, then compare against session log mtimes.

---

## Step 3 — Broken Backlinks

Scan all `[[link]]` references in wiki articles. For each `[[slug]]`, check:
- Does `wiki/clients/<slug>.md` exist? Or `wiki/projects/<slug>.md`? Or `wiki/systems/<slug>.md`?
- If none match → flag as `[BROKEN_LINK]`

```bash
grep -rh '\[\[' wiki/ | grep -o '\[\[[^]]*\]\]' | sed 's/\[\[//;s/\]\]//' | sort -u
```

For each slug found, normalize before checking:
1. Strip leading `wiki/` prefix if present → flag as `[BAD_FORMAT]` (seeding agents sometimes write wrong format)
2. Strip trailing `.md` extension if present → also flag as `[BAD_FORMAT]`
3. Check existence: `wiki/<slug>.md`, `wiki/clients/<slug>.md`, `wiki/projects/<slug>.md`, `wiki/systems/<slug>.md`, `wiki/patterns/<slug>.md`
4. If no file found after normalization → flag as `[BROKEN_LINK]`

Note: `[[systems/neptune]]` will always show as broken until neptune is seeded — that's expected.

---

## Step 4 — Index Gaps

Read `wiki/index.md`. For every `.md` file in `wiki/clients/`, `wiki/projects/`, `wiki/systems/`:
- Is it listed in `wiki/index.md`? If not → flag as `[NOT_INDEXED]`

Conversely, for every row in `wiki/index.md`:
- Does the linked file actually exist? If not → flag as `[DEAD_INDEX_ENTRY]`

---

## Step 5 — Compilation Queue Cleanup

Read the `## Compilation Queue` section in `wiki/index.md`. For each entry:
- Does the corresponding `wiki/<type>/<slug>.md` file now exist? If yes → flag the queue entry as stale, suggest removing it.

---

## Output Format

Emit a clean lint report:

```
## Wiki Lint Report — YYYY-MM-DD

### Missing Articles (N)
[MISSING] wiki/clients/evs.md — 1 session log (2026-04-17)
...

### Stale Articles (N)
[STALE] wiki/clients/cascades-tucson.md — compiled 2026-05-24, 3 new logs since
...

### Broken Backlinks (N)
[BROKEN_LINK] wiki/clients/kittle.md → [[gururmm]] (no file found)
...

### Index Gaps (N)
[NOT_INDEXED] wiki/clients/new-client.md — not listed in index.md
...

### Compilation Queue — Stale Entries (N)
[QUEUE_STALE] client:birthbiologic — wiki/clients/birth-biologic.md exists; remove from queue
...

### Summary
- N missing articles → run /wiki-compile for each
- N stale articles → run /wiki-compile to refresh
- N broken links → fix manually or after recompile
- N index gaps → update wiki/index.md
```

After the report, ask: "Run /wiki-compile for any of the missing articles now?"
