DeepThonk tools 16
deepthonk.planEstimate calls and sequential rounds for a profile (no model calls). Use before paid runs.deepthonk.startStart a run in the background; returns `run_dir`, `job_id`, and job-scoped artifact resources.deepthonk.statusPoll job status from a `run_dir`.deepthonk.resultReturn final summary + winner once a job is complete.deepthonk.cancelRequest cancellation by writing `cancel.json` into the run directory.deepthonk.lock_inspectInspect lock ownership and explicitly reclaim only an exact fingerprint.deepthonk.repair_budgetReplace legacy `[redacted]` numeric budget fields with explicit original values.deepthonk.runBlocking convenience: start + await completion in one call. Prefer `start` + polling for long-running jobs.deepthonk.rankRank a user-supplied candidate set with pairwise judging + Bradley-Terry (skip generation).deepthonk.mutateMutate one supplied candidate with critique (one-shot).deepthonk.resumeDetect whether a run can be resumed; with `continue: true`, replay from the last validated phase boundary.deepthonk.exportExport run summary or full trace in JSON or markdown.- +4 more on the listing page
