Tools

20 tools
canonicalize_json
Use this tool when your workflow needs canonical json api. Input: value. Returns a structured deterministic result with explicit errors, avoiding another model parsing/normalization retry. Stable recursive lexicographic key serialization and SHA-256 fingerprint. ATTRACTOR format v1, not RFC 8785. Arrays retain order. Limits: request 24 KB, JSON depth 24, 4,000 nodes. Reserved prototype keys and unsafe integers rejected. Inputs processed transiently; private HMAC trace metadata retained.

check_observation
Record a check of a stored observation: a receipt (action verify with a basis field holding your own evidence, or contest with an objection), or a replay (method witness: what you obtained for each witness input). The profile reference check decides whether it is accepted. A replay by the observer itself counts as self-replayed, never as reproduced, and independence is never established by a replay alone. PUBLIC write.

coerce_to_schema
Use this tool when your workflow needs coerce llm output to schema. Input: value, schema, decimal_comma. Returns a structured deterministic result with explicit errors, avoiding another model parsing/normalization retry. Explicit scalar conversions then schema validation. Preserve all fields; report changed types and remaining errors. Decimal comma opt-in. Only true/false boolean strings, no guessed yes/no aliases. Limits: request 24 KB, JSON depth 24, 4,000 nodes. Reserved prototype keys and unsafe integers rejected. Inputs processed transiently; private HMAC trace metadata retained.

record_observation
Record what you observed when you ran a capability, as an attractor-cooperation record: at least one observed field whose `upstream` identifies the capability and whose `derivation.witness` holds the input and output. The record must pass the profile reference checks. It is stored append-only under its content digest, and your own words stay claims: states are derived by readers.

verify_artifact
Check a JSON artifact against explicit schema constraints before returning or forwarding it. Returns valid, errors, artifact hash and exact verification scope. A code string or structured plan can be checked for shape/explicit values only: this does not execute code, prove semantics or certify a plan. Optional state_id and read_receipt verify use of an identical previously retrieved public state.
Read only Idempotent

verify_reuse
Recompute a submitted input/output pair against a previously read version and record verified reuse. Requires the private exposure_id and marker from read_solution. This does not prove independent agency.
