Tools

Token cost is the o200k count of the tools list JSON, including schemas, before any tool is called.

• get_time

  Query an NTP server for current UTC time and this clock's offset. Appends the sample to the drift log and returns the trend inline: current offset, drift rate (ms/day), and whether the clock is stable

• generate_uuid

  Generate one or more random UUIDv4 identifiers -- for records, sessions, and IDs created in agent pipelines.

• diff

  Unified diff between two texts, with added/removed line counts. For reviewing edits, comparing outputs, or validating transformations.

• calculate

  Evaluate a math expression safely: + - * / // % **, parentheses, functions (abs round min max sqrt floor ceil exp log log2 log10 pow sin cos tan), constants pi e tau inf. Parsed to an AST and only whi

• attest

  Wrap any payload in a tamper-evident record: a UUID, a timestamp (NTP-verified when reachable, local clock otherwise -- the record says which), and a sha256 over the canonical record. One call, the re

• verify

  Check a record produced by attest: recompute the sha256 over the record and compare. Pass/fail -- did this payload produce this hash at this timestamp. Any modified field breaks it.
