- ai-stress-testarcasilesgroup/ai-engineeringTest system behavior under extreme load to find breaking points, capacity limits, and failure modes. Covers stress, spike, and breakpoint testing with k6 (primary), JMeter, or Locust. Refuses unbounded concurrency and production saturation without explicit approval. Trigger for "stress test", "load test until it breaks", "find the breaking point", "capacity test", "spike test", "how much traffic can we handle", "system limits", "what's our max load". Not for frontend performance or Core Web Vitals — use /ai-audit-design. Not for general load testing to validate expected traffic — use /ai-verify with existing benchmarks. Not for diagnosing a performance failure — use /ai-debug.TestingNo warnings★ 61↓ —
- ai-agents-mdarcasilesgroup/ai-engineeringCreates, audits and maintains the AGENTS.md a repository owes its coding agents, following the agents.md convention (https://agents.md/). Decides root-only versus nested AGENTS.md files from the repo's real shape, interviews the tree (not the user) for build/test/lint commands, and writes only what an agent cannot deduce from the code. Audits a set that already exists: a rule the code states, a child repeating its parent, a command that no longer runs, a zone with no route in. Also the in-session maintenance path: a governed agent MAY edit AGENTS.md directly (blueprint §9.2 — it is not sacred) when the repo's real state made a rule stale. Trigger for "create AGENTS.md", "update AGENTS.md", "audit AGENTS.md", "split AGENTS.md", "AGENTS.md is too long", "the agent reads the wrong file", "the agent ignores our conventions", "set up agent instructions", "edit AGENTS.md". Not for runtime agent contracts (goals, gates, budgets) — use /ai-orchestrator. Not for documentation users read — use /ai-write.TestingNo warnings★ 61↓ —
- grill-meAvdLee/RocketSimAppInterview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree.

- pyvene-interventionsKalarisLabs/research-agent-skillsProvides guidance for performing causal interventions on PyTorch models using pyvene's declarative intervention framework. Use when conducting causal tracing, activation patching, interchange intervention training, or testing causal hypotheses about model behavior.TestingNo warnings★ 61↓ —
- gsd-add-testscoco-research/cocoUse when a completed phase needs unit or E2E tests, or the user asks to add tests for phase N. Classifies implementation files into TDD, E2E, or skip, gets plan approval, then generates RED-GREEN tests from SUMMARY.md and UAT criteria.TestingNo warnings★ 787↓ —
- ai-prarcasilesgroup/ai-engineeringThe pull-request loop, opened from the local `main` with no worktree: cut the pull-request branch from the local `main`, push it, open the pull request against `main` with a body assembled from the merge commits the branch carries, watch CI and the review comments, fix only what is obvious in bounded iterations, then merge with auto-merge on by default. The human's verb decides how far the run goes: "open the pull request" opens it and stops, while "finish the PR", "land the PR", "merge it" or "run the full PR loop" carries the run through the merge — an ask that names neither is the open one. A session that is still building never pushes. Not for diagnosing non-CI failures — use ai-debug. Not for adding test coverage — use ai-verify.TestingNo warnings★ 61↓ —

- arize-datasetArize-ai/arize-skillsCreates, manages, and queries Arize datasets and examples. Covers dataset CRUD, appending examples, exporting data, and file-based dataset creation using the ax CLI. Use when the user needs test data, evaluation examples, or mentions create dataset, list datasets, export dataset, append examples, dataset version, golden dataset, or test set.TestingNo warnings★ 66↓ —

- create-callVapiAI/skillsCreate one-off outbound phone calls, web calls, scheduled calls, and simple batch calls using the Vapi API. Use when making or testing individual calls or initiating a bounded /call request programmatically.

- correctNewdsebban/skillsFind the mistakes agents keep repeating in this repo and make each one impossible. Try architecture first, then types, then a lint whose error names the fix, then a test, and write docs last. Prove each check fails on a real past mistake. Repeat this each time the operator corrects you. Use for /skill:correct.TestingNo warnings★ 68↓ —
- positioningmatteotitta/repo-structure-in-houseDevelops B2B SaaS positioning from your ICP, competitor and win-loss evidence. Maps what buyers compare you to, chooses between leading with a category or a problem, picks a primary and secondary anchor and up to three defensible differentiators, lays out 2 to 4 worked positioning options with a comparison canvas so you can decide, then locks the chosen one and tests it (clarity ladder, guarantee test). Triggers: "positioning", "how do we position", "what category are we in", "how do we differentiate from", "our homepage is confusing", "positioning options". Run before /messaging. Not for taglines or a messaging library (use /messaging).TestingNo warnings★ 68↓ —
