Triggers on "create issue", "list issues", "update status", "track task", "project management", "milestone progress".
lipton-mutation-testing
by copyleftdev
Evaluate test quality in the style of Richard Lipton, father of mutation testing. Emphasizes injecting small faults (mutants) to measure test effectiveness, the competent programmer hypothesis, and the coupling effect. Use when assessing test suite quality, improving test coverage, or building mutation testing tools.
ideate
by biruk741
Structured brainstorming and idea development for hackathon projects. Guides the team through problem definition, solution framing, demo visualization, and scope scoping. Use when the team needs to develop, refine, or evaluate a hackathon project idea. Also use when someone says "let's brainstorm", "what should we build", "help me think through this idea", or needs to evaluate multiple competing ideas.

monitor
by Sytex
Read-only infrastructure monitoring. Use when user asks about pod status, deployments, CPU, memory, restarts, 502 errors, slowness, cluster health, or wants to check if environments are running correctly.
analyzing-experiment-precompute-canary
by PostHog
Analyze the experiment precompute result-consistency canary across prod-US and prod-EU, deep-dive any issues, and produce an actionable report. Sweeps the canary's Prometheus health gauges in both regions, and when anything is unhealthy pulls the structured divergence/failure logs from Loki to reconstruct exactly which (team, experiment, metric) went wrong, by how much, and which class of divergence it is (stability vs correctness, and for correctness whether exposure counts or only values differ). Mechanism-level root cause needs ClickHouse and is out of scope — the skill hands off with precise drill-down steps. Use when the user asks to check / analyze / verify the experiment precompute canary, investigate a canary divergence or alert, or confirm precomputed experiment results are consistent in production. All data comes through the Grafana MCP (Prometheus + Loki) — no payload decryption, no ClickHouse.
