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 (3)

`get_ai_crawler_policy`read-only	Which of the eight tracked AI crawlers a domain's robots.txt admits, and whether it publishes an llms.txt. Three states per agent: allowed, disallowed, unspecified. Unspecified is NOT allowed, because a catch-all Disallow blocks an agent the file never names, so read `effective` for what is in force. Reads the last stored reading; it does not fetch the file.
`list_sources`read-only	What Domduck reads and what each source means, including the eight AI crawlers whose robots.txt policy is tracked. A constant. Read it first: it is what lets a model interpret lookup_domain without guessing at field names or at which direction is better.
`lookup_domain`read-only	Public reputation snapshot for one domain from Domduck's store: Domain Rating, Tranco rank, OpenPageRank, registration date, TLS certificate state and AI crawler policy. Returns hasReading false for a domain nobody has looked up yet, which is a real answer and not an error. One domain per call, and no history: the dated series is what a Domduck account is for.

Schemas: list_tools.
