io.github.openclaw/openclaw/openclaw-pr-maintainer

Use immediately for any pasted OpenClaw GitHub issue or PR URL/number, and for OpenClaw issue/PR orchestration, review, triage, root-cause repair, PR rewrite, duplicate search, opener identity/who wrote it, author account age/activity, comments, labels, close, land, or maintainer evidence checks.

io.github.PostHog/posthog/debugging-experiments

Debug and support PostHog Experiments (A/B tests) for a customer looking at their own results. Use whenever an experiment support ticket is pasted or a customer asks a results question, most commonly "why aren't my exposures even?", "why is one variant getting no traffic?", "why am I missing / seeing too few exposures?", "why does the bias banner show?", or "why don't PostHog's numbers match my SQL?". Pulls the experiment's real data read-only, matches it to a known-cause catalog, and produces a customer-facing explanation, fix, and review of the pertinent numbers. Loads diagnosing-experiment-results as its deep diagnostic library. DO NOT TRIGGER when: creating an experiment (use creating-experiments), only configuring rollout (configuring-experiment-rollout) or metrics (configuring-experiment-analytics), asking lifecycle questions (managing-experiment-lifecycle), or the underlying feature flag is what's misbehaving rather than the results (use debugging-feature-flags).

Covers discovering per-team GitHub warehouse tables via engineering-analytics-sources, replicating curated column semantics in HogQL, reading exposed engineering_analytics_* warehouse views where product logic is involved (CI cost, fingerprinted failure lines, commit attribution), saving queries with insight-create, and scheduling delivery with subscriptions-create.

io.github.PostHog/posthog/posthog-desktop

Scopes work to the desktop app at products/desktop — a nested standalone pnpm/turbo/Biome workspace imported from the now-archived PostHog/code repo, with posthog/posthog the only source of truth for PRs, CI and publishing, and not part of the root frontend or Django build. Use when the user says /posthog-desktop, or works on the Electron desktop app, apps/code, apps/web, apps/mobile, packages/core, packages/ui, packages/workspace-server, @posthog/api-client, @posthog/agent, or the agent framework. Pins the working directory to products/desktop, swaps in that tree's toolchain and conventions in place of the monorepo's, and defines the few paths outside the tree that may be touched (Django APIs the app calls, desktop-* CI at the root).
