Dungbeetle tools (12, 4 write)
write = sends, deletes, buys or postsRead from the package source without running it. The installed server may list more.
dungbeetle_approve_runwrite actionApprove a run. With promote=true, the run's candidate snapshots become new hosted baseline versions — this MUTATES baselines and should be confirmed by a human first. Returns the recorded review and any promoted targets.
dungbeetle_get_analyticsPass rate, run trend, and per-target flakiness over the recent run window. Use to spot flaky targets before approving.
dungbeetle_get_baseline_historyFull version history for one baseline target (versions, digests, timestamps).
dungbeetle_get_repositoryReturn the repository the configured credentials resolve to (id, name). Everything else is scoped to it.
dungbeetle_get_review_urlDeep link to the web review page for a run, where a human reviews diffs and approves baselines.
dungbeetle_get_runwrite actionStructured summary of a run for triage: per-target status, counts, changed targets, current review state, and a review URL. Use detail="full" to include the text diff per target. Screenshots are never inlined — open the review URL for images.
dungbeetle_get_usageCurrent-period usage (snapshots ingested, storage bytes, repositories) alongside the plan limits it is measured against, plus any active quota warnings. Use to check quota before pushing runs or baselines.
dungbeetle_healthLiveness/version probe for the configured Dungbeetle server. Use to confirm connectivity before other calls.
dungbeetle_list_baselinesList the repository's baseline targets with their latest version and last-updated time. Start here to see what's under test.
dungbeetle_list_runsList recent runs for the repository, newest first — use this to discover a run id to triage with dungbeetle_get_run. Returns compact per-run summaries (id, status/passed, mode, branch, commit, createdAt, reviewState, failedCount, url); no diffs, no images.
dungbeetle_reject_runwrite actionReject a run's changes (records a rejected review in the append-only audit trail). Does not modify baselines.
dungbeetle_reopen_runwrite actionReopen a previously approved or rejected run by setting its review state back to pending, so it can be re-reviewed. Recorded in the append-only audit trail; does not modify baselines.
