Tools (6)

  • 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, drifting, or accelerating.

  • 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 whitelisted nodes are computed -- no eval(), no names, no arbitrary code.

  • 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 record is complete and tamper-evident.

  • 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.
