Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (5)

`archive_days`	List the archived daily editions (dates) available from the free digest. Use to find which dates can be cited.
`daily_signals`	Today's AI signals from Signals API: exactly 4 items, one from each core source (GitHub, Hugging Face, YouTube, Silicon Valley news), each linking to the original. Use when the user asks what's new in AI today.
`top_models`	Hugging Face models we track, with rank, rank change and 7-day momentum. Entries without a derivable number are marked 'not ranked' with a reason instead of a guessed value.
`top_repos`	GitHub repositories we track, with rank, rank change and momentum. Use when the user asks which open-source AI projects are trending.
`what_changed`	What changed in the AI landscape since the previous snapshot: new entries, entities no longer seen, and rank movers. Use when the user asks what's moving, rising, or different lately.

Schemas: list_tools.
