Interact with Mission Control — AI agent orchestration dashboard. Use when registering agents, managing tasks, syncing skills, or querying agent/task status via MC APIs.

Operating procedure for the conflict-autoresolver agent: sweep open PostHog/posthog PRs that conflict with master, resolve the trivial conflicts (generated artifacts deterministically, source conflicts with judgment), land one merge commit on the PR head, and flag everything else for a human. Use when running as the scheduled conflict autoresolver, when asked to sweep or auto-resolve merge conflicts against master, or when asked to bring a conflicting PR up to date without rewriting its history. Trigger terms: conflict sweep, autoresolve, merge conflicts, conflicting PRs, bring PR up to date, restack. Operators setting up the automation itself: see references/routine-setup.md.

Debugs a TableAccessDeniedError from an error tracking issue, Slack alert, or user report. Use when investigating why HogQL denied a system or warehouse table and whether the occurrence is a real bug or expected behavior. Trigger terms include TableAccessDeniedError, table_access_denied, and "You don't have access to table".

Audit already-implemented Data warehouse import sources for endpoints, schemas, and tables the vendor's API offers but we never wired up. Use when asked whether a source is missing endpoints, to find new endpoints a vendor has added since a source was built, to refresh COVERAGE_GAPS.md, to prioritize which source to deepen next, or to check coverage before an integration review. Covers dumping our real endpoint inventory credential-free, ranking sources by production adoption, diffing against vendor OpenAPI/GraphQL specs, and recording findings. Not for implementing a source (use implementing-warehouse-sources), adding a vendor API version (warehouse-source-new-version), or writing source docs (documenting-warehouse-sources).

Decides whether a behavior-changing fix needs an in-app notice, then builds one that reaches only the affected users and can be removed later. Use when a change alters what an existing user sees without them doing anything — a metric moves, a chart shifts, a count drops, a date range resolves differently, a matcher matches differently — and when adding, reviewing, or removing such a notice. Trigger terms: behavior change, breaking change, semantics change, "results may differ", change notice, deprecation banner, migration banner. Carries the gate (narrow to the affected users with a tested predicate, or do not ship a notice at all), the pattern from `SqlInsightDateFilterNotice`, where to anchor the notice, and the flag-based removal path. Not for new features (use the changelog), not for permanent per-object warnings computed by the backend, and not for the wording itself (see `/writing-user-facing-copy`).

Configures and manages Depot CI, a drop-in replacement for GitHub Actions that runs workflows entirely within Depot. Use when migrating GitHub Actions workflows to Depot CI, running `depot ci migrate`, managing Depot CI secrets and variables, running workflows with `depot ci run`, debugging Depot CI runs with `depot ci run list`, `depot ci status`, `depot ci logs`, `depot ci diagnose`, or `depot ci ssh`, inspecting test results with `depot tests` or run artifacts with `depot ci artifacts`, checking workflow compatibility, or understanding Depot CI capabilities. Also use when the user mentions .depot/ directory, depot ci commands, or asks about running GitHub Actions workflows on Depot's infrastructure without GitHub-hosted runners. Also use when comparing what Depot CI and GitHub Actions report for a skipped, empty-matrix or continue-on-error job, or when working out whether a check run satisfies a required status check or a merge queue.

Design, extend, review, or debug PostHog Hobby end-to-end smoke tests in bin/hobby-ci.py and .github/workflows/ci-hobby.yml. Use when adding an ingestion round trip, deciding whether a product belongs in Hobby CI, changing the CI Hobby service topology or API-key scopes, or diagnosing a smoke test that captures data but cannot query it.

Finds and ranks callers that could move from services/llm-gateway to PostHog/ai-gateway. Use when asked what to migrate next, to find low-risk gateway migration candidates, to audit remaining Python gateway callers, or to identify callers blocked by Go gateway parity. Searches code and deployment wiring, inventories each caller's required contract, filters out unsupported migrations, and returns an evidence-backed shortlist without changing callers.
