Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names explicitly indicate their purpose (e.g., 'check_feature_support').
- Descriptions explain use cases (e.g., 'when the id is already known').
- Required parameters are clearly defined.
Weaknesses
- Some descriptions are cut off (e.g., 'Us' at end of check_feature_support).
- Parameter 'q' in search_features is less intuitive than 'query'.
- Limited detail on output structure (e.g., 'safe_to_use' flag explanation).
check_feature_support— Description ends abruptly with 'Us' (possible typo).search_features— Parameter 'q' is non-descriptive compared to 'query'.

Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
check_feature_supportCan I use this feature, and from which browser version? Accepts a loose name (":has()", "container queries", "css-grid") and resolves it to a caniuse feature, then returns the earliest continuously-supported version per major browser, global usage percentage, and a conservative safe_to_use flag. Use this first; it answers the whole question in one call.
featurestringrequired
get_feature_by_idSupport table for an exact caniuse feature id. Use when the id is already known, for example from a previous search. No fuzzy matching is applied.
idstringrequired
search_featuresFind the caniuse feature id for a loose query. Use when a query is ambiguous and you want to choose between candidates before checking support.

- Publish a webpage to a live URL, straight from your AI.yapp.page
Yapp turns "build me a page and publish it" into a live URL. Connect once (browser OAuth, or a token for terminal clients) and your AI can publish a webpage from HTML, or host a PDF, image, or ZIP exactly as-is to a public `<slug>.yapp.page` URL in seconds, then update, password-protect, set expiry, attach a custom domain, or read form submissions, all by asking. Free to start; no local install. **Tools (15):** `publish_page`, `publish_file`, `update_page`, `delete_page`, `get_page_stats`, `list_my_pages`, `rename_page`, `change_page_slug`, `set_page_expiry`, `set_page_password`, `list_submissions`, `add_custom_domain`, `list_custom_domains`, `check_custom_domain`, `remove_custom_domain`.
