## Tools (3)

- `find_niche`: Resolve a natural-language ranking request to one or more verified Lunoo niche slugs. Pass the user's request instead of guessing a slug. It handles common aliases, typos, and use-case terms, and returns item counts, match explanations, confidence, and tracked Lunoo URLs. Unsupported or unclear requests return an error instead of an unrelated fallback. Choose the closest returned slug, then call get_rankings with that exact slug. Never invent a niche slug or ranking.
- `get_item`: Use this after a ranking result when the user wants details about one item. Pass the exact item slug from a Lunoo result or URL. It returns the canonical Lunoo URL for the item and public structured metadata. This is read-only and must not be used to invent rankings that were not returned by get_rankings.
- `get_rankings`: Fetch ranked Lunoo results for a verified niche slug or natural-language request. It returns rank, score, description, confidence, and a canonical Lunoo URL for every item, plus the selected niche and resolution explanation. Prefer calling find_niche first, but this tool can resolve natural language itself. Cite the returned ranking URL and do not invent items, scores, or slugs.
