### Key gotchas

1. **Tool descriptions are `undefined`** — no description strings set
2. **Errors NOT flagged via `isError`** — non-existent articles return error text as regular content
3. **`readArticle` returns FULL article markdown** — large articles = 5-9s, many KB. No section targeting
4. **`search` returns ONE best-match summary** — not a ranked list
5. **Empty search returns mixed output** — 'No results found' + error stack trace
6. **`pageId` works but returns whatever page has that ID** — user talk pages, disambiguation, etc.
7. **Network-dependent** — all calls hit Wikipedia API; 1-2s search, 3-9s articles
8. **Entry point:** `dist/index.js` (ESM module type)
