Tools (15)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • artifact_verify

    Verify a contract bundle's authenticity + evidence without trusting it. Read-only.

  • candidate_inspect

    Inspect one candidate moment: onset, measured components (severity/input_health/recurrence/novelty/covered_by_contract), and trust findings. Read-only; never labels.

  • candidate_list

    List top candidate moments awaiting human review. Read-only; never labels.

  • clone_cleanup

    Clone-scoped: delete a STAGING clone THIS tool created, authorized by its durable clone receipt (referenced by trial_id or receipt_id) -- never a raw clone id or display name. Never touches production.

  • contract_list

    List contracts in a workspace. Read-only.

  • counterexample_compile

    Compile one deterministic scripted-scenario failure into a private proof-preserving .hotato-repro capsule. Offline; inputs and output are sandboxed; existing output is never replaced.

  • counterexample_reproduce

    Run a private capsule's reduced fixture under the current Hotato evaluator. Permits evaluator-version drift while requiring the source-selected structured failure branch. Read-only.

  • counterexample_verify

    Audit a private .hotato-repro capsule: manifest, frozen source, proof-engine provenance, delete-only chain, exact failure, and claimed local minimality. Read-only.

  • experiment_create

    Clone-scoped: precommit a trial manifest from a committed battery BEFORE any capture, so the fixture universe is fixed ahead of the results. Never captures, never deploys.

  • experiment_propose

    Propose a bounded variant set with expected effects. Read-only; does not clone, apply, or deploy.

  • experiment_run

    Clone-scoped: recompute a before/after trial (offline, no network, no production mutation) and record a recommendation. Names any pending human-gated action.

  • experiment_status

    Report a trial's current verdict, evidence tier, recommendation, manifest hash, and any pending human-gated action. Read-only.

  • fleet_status

    Read the local fleet workspace rollup (counts + jobs). Read-only.

  • trial_explain

    Explain a recorded trial's verdict, evidence tier, recommendation, and any pending human-gated action. Read-only.

  • voice_eval_run

    Description is built at runtime.
