- dif-triage-experimentsdif-sh/difTriage every running dif.sh experiment and rollout from the dif cloud overview.

Use when the user asks to triage experiments, review all experiments, see what needs action, ramp, turn off, kill, find winners, or check the dif cloud overview.TestingNo warnings★ 114↓ —Also in 1 other repo
- grillingGulajavaMinistudio/awesome-copilot-idGrill the user relentlessly about a plan or design. Use when the user wants to stress-test a plan before building, or uses any 'grill' trigger phrases.TestingNo warnings★ 86↓ —
- mini-program-release-skillNocodeMrLi/mini-program-engineering-skill-suiteGovern mini-program release readiness and evidence across source branches, semantic versions, build artifacts, test flags, debug paths, sensitive data, permissions, privacy declarations, platform uploads, review submissions, staged versions, production releases, and rollback plans. Use when users ask for a release checklist, packaging, export, version bump, upload readiness, submission readiness, launch status, rollback preparation, or a precise judgment of what has and has not shipped. Defaults to read-only preflight, requires separate explicit authorization for every external state change, and never treats a Git push, successful build, platform upload, review submission, approval, or production publication as interchangeable.TestingNo warnings★ 91↓ —
- mini-program-implementation-skillNocodeMrLi/mini-program-engineering-skill-suiteImplement bounded features and fixes in existing or new mini-program codebases while preserving repository rules, user-owned changes, approved behavior, assets, framework conventions, and evidence boundaries. Use when users ask to write or modify mini-program code, implement a confirmed specification or architecture, add a scoped feature, remove behavior semantically, update internal documentation required by a change, or carry out a well-defined small fix that does not require root-cause investigation. Establishes a baseline and change boundary, applies test-driven small steps, distinguishes source from generators and build artifacts, verifies the affected contract, and never reports source completion as device validation, formal acceptance, upload, or release.TestingNo warnings★ 91↓ —
- lite-toolsejboy/agent-scriptsUse compact wrappers when running routine Maven builds and tests, supported npm/Node test workflows, or Go tests. Select mvn-lite for supported Maven build and test workflows, npm-lite for npm run verify, npm run test:unit, or node --test, and go-lite for go test.TestingNo warnings★ 117↓ —
- assumption-prioritizationitseffi/agentic-osPrioritize assumptions by risk and importance. Use after assumption mapping to decide what to test first.TestingNo warnings★ 117↓ —
- tdditseffi/agentic-osTest-driven development - write failing test first, then minimal code. Use before implementing any feature or bugfix.TestingNo warnings★ 117↓ —
- mini-program-verification-skillNocodeMrLi/mini-program-engineering-skill-suiteVerify mini-program implementations and fixes with risk-calibrated evidence across static checks, unit tests, integration tests, state matrices, simulators, real devices, cloud environments, and release artifacts. Use when users ask to test, validate, accept, regression-check, quality-check, confirm readiness, or determine whether a mini-program feature is actually complete. Binds results to a source and build fingerprint, records commands and observable evidence, separates passed, failed, blocked, and not-run layers, prioritizes the next highest-information check, and never converts local success into device, cloud, release, or formal acceptance claims.TestingNo warnings★ 91↓ —
- ank-tddhaksolot/ankDrive an implementation test-first, red before green, against a claimed task's frozen criterion. Use when implementing a task in a repository with a .ank/ directory.TestingNo warnings★ 91↓ —
- rust-best-practicesapollographql/skillsGuide for writing idiomatic Rust code based on Apollo GraphQL's best practices handbook. Use this skill when: (1) writing new Rust code or functions, (2) reviewing or refactoring existing Rust code, (3) deciding between borrowing vs cloning or ownership patterns, (4) implementing error handling with Result types, (5) optimizing Rust code for performance, (6) writing tests or documentation for Rust projects.TestingNo warnings★ 118↓ —

- ank-diagnosehaksolot/ankWork a defect back to its cause before changing anything, and close it with a regression test. Use when a claimed task's criterion names a defect in a repository with a .ank/ directory.TestingNo warnings★ 91↓ —
- optimize-pipelineharness/harness-skillsOptimize Harness CI/CD pipeline performance via MCP. Configure parallel test execution with Test Intelligence, design multi-layer caching strategies, analyze pipeline bottlenecks with stage-level timing breakdowns, optimize cache hit rates, and design monorepo CI pipelines with selective builds. Use when asked to speed up pipelines, improve cache hit rates, set up parallel testing, optimize build times, or configure monorepo builds. Do NOT use for creating new pipelines (use create-pipeline instead) or debugging failures (use debug-pipeline instead). Trigger phrases: pipeline speed, slow pipeline, cache hit rate, parallel tests, test intelligence, build optimization, caching strategy, monorepo pipeline, pipeline bottleneck, build speed.TestingNo warnings★ 125↓ —
- chaos-experimentharness/harness-skillsUse when the user asks to create, edit, update, design, or configure a Harness Chaos Experiment — including faults, probes, actions, experiment YAML, fault injection, pod-delete, or resilience tests. Do not use for Chaos steps inside a pipeline or a DRTest stage; use chaos-dr-test for those. Do not use to run an experiment, list past runs, or inspect run results — call the Chaos MCP tools directly for those (see Performance Notes). Trigger phrases: chaos experiment, chaos engineering, resilience test, fault injection, pod-delete, chaos hub template.TestingNo warnings★ 125↓ —
