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 (4)

`attester_package_exists`read-only	Does this PyPI or npm package name really exist? Deterministic answer from the real published artifact, signed, with typosquat-adjacency flags on misses. Free: 25 calls/day per client IP, shared with the /demo/v1/* HTTP routes, reset 00:00 UTC. Higher volume: paid HTTP routes at https://attester.dev/llms.txt.
`attester_symbol_exists`read-only	Does a function, class, or constant exist in this PyPI or npm package? Answer from the indexed artifact, with closest-match suggestions on misses. Free: 25 calls/day per client IP, shared with the /demo/v1/* HTTP routes, reset 00:00 UTC. Higher volume: paid HTTP routes at https://attester.dev/llms.txt.
`attester_symbol_signature`read-only	Exact signature, structured params, docstring summary, and deprecation status for one symbol, resolved at a pinned version when given. Free: 25 calls/day per client IP, shared with the /demo/v1/* HTTP routes, reset 00:00 UTC. Higher volume: paid HTTP routes at https://attester.dev/llms.txt.
`attester_version_diff`read-only	Symbol-level diff between two pinned versions of one package: added, removed, changed signatures, new deprecations, and a breaking/additive/neutral classification. Free: 25 calls/day per client IP, shared with the /demo/v1/* HTTP routes, reset 00:00 UTC. Higher volume: paid HTTP routes at https://attester.dev/llms.txt.
