- prd-v07-test-planningmattgierhart/PRD-driven-context-engineeringDefine test cases BEFORE implementation, ensuring every API, business rule, and user journey has verifiable acceptance criteria during PRD v0.7 Build Execution. Triggers on requests to define tests, plan test coverage, create test cases, or when user asks "define tests", "test planning", "what to test?", "test cases", "test coverage", "TEST-", "test-first". Consumes EPIC- (scope), API-, DBT-, BR-, UJ-. Outputs TEST- entries with Given-When-Then format. Feeds v0.7 Implementation Loop.TestingNo warnings★ 181↓ —Also in 1 other repo

- secret-handlingUpdatedarbiterForge/codeArbiterThe secret-source gate. Routed to when changed code reads, writes, or passes a secret — API key, token, password, connection string, signing key, certificate, or any value that grants access. Validates that every secret comes from the approved store and never lands in source, log, test fixture, error response, image, or LLM prompt. The auth-crypto-reviewer agent is dispatched as the reviewer.TestingNo warnings★ 148↓ —

- matlab-model-serdes-systemsmatlab/matlab-agentic-toolkitModel, simulate, and optimize Serializer/Deserializer (SerDes) systems — serial and parallel links — using MATLAB SerDes Toolbox. Design NRZ and PAM-N links (PAM3 through PAM16) — explore equalization architectures (FFE, CTLE, DFE), sweep or optimize parameters with genetic algorithms, and characterize channels from loss models, S-parameter files, or crosstalk scenarios. Process captured waveforms through equalization chains, build eye diagrams, and decompose jitter. Deliver IBIS-AMI models for Tx, Rx, Redriver, or Retimer by exporting to Simulink and compiling .ami/.ibs/.dll/.so files. Covers the full arc from initial design exploration and parameter optimization to compliance testing and compiled model validation, including custom datapath blocks for nonstandard equalization.TestingNo warnings★ 1.2K↓ —
- qafishzjp/qa-skillsEnd-to-end QA entry: "test this feature fully" orchestrates requirements, strategy, cases, review, execution, bugs, regression, report; resumable. Single-stage tasks use their stage skill. 端到端测试唯一入口：“帮我测试这个需求/功能”时编排需求→策略→用例→审查→执行→Bug 分析→回归→报告，落盘可续跑；单阶段诉求直接用对应阶段 skill。TestingNo warnings★ 50↓ —
- integration-e2e-testingshinpr/agentic-codeApplies integration and E2E implementation, mock-boundary, and review rules. Use when: writing integration or E2E tests or reviewing their quality.TestingNo warnings★ 50↓ —
- author-modeladvisor-checksmatlab/simulink-agentic-toolkitAuthor or upgrade Model Advisor checks for Simulink and System Composer models. Covers the full lifecycle: guideline authoring, check specification, Model Advisor check implementation, and qualification testing. Use when creating new checks (edit-time, standard batch, config-parameter, auto-fix), converting legacy StyleOne/StyleTwo/StyleThree checks to modern DetailStyle, creating a guideline for modeling, enforcing a modeling rule, or testing/qualifying a check. Triggers on any modeling constraint (e.g., "blocks shall...", "signals must match...", "parameters shall be set to...").TestingNo warnings★ 1.3K↓ —
- inject-faultsmatlab/simulink-agentic-toolkitAdd, configure, and manage faults on Simulink, Simscape, and System Composer model signals for robustness analysis and safety validation. Use when injecting faults (stuck, noise, gain, offset) onto block inports/outports, enabling fault simulation, or analyzing fault effects. Covers sensor failures, signal corruptions, actuator faults, FMEA validation, and robustness testing. Requires Simulink Fault Analyzer.TestingNo warnings★ 1.3K↓ —
- simulink-use-c-function-blockmatlab/simulink-agentic-toolkitUse when integrating legacy code, custom code, or C/C++ code into Simulink via C Function blocks. Configure Simulink C Function blocks programmatically using the SymbolSpec API. TRIGGER when the user: - Asks about calling or wrapping C/C++ code or libraries in Simulink - Wants to create, configure, or use a C Function block - Mentions integrating custom code, legacy code, or external C/C++ into a model - Asks to integrate a C++ class into a Simulink model or test bench - Mentions inputs/outputs/parameters for a C++ algorithm blockTestingNo warnings★ 1.3K↓ —
- fix-sldv-incompatibilitymatlab/simulink-agentic-toolkitUse when a Simulink model is incompatible with Simulink Design Verifier (sldvcompat returns false, or an SLDV analysis errors out on an unsupported construct) and needs to be made analyzable. Diagnoses the incompatibility, applies the matching fix to a copy, and confirms the copy is compatible; optionally raises confidence the fix preserved behavior via a back-to-back consistency replay (agreement on the generated tests, not a proof of equivalence). Do NOT use for running test generation, design error detection, or requirement verification themselves — only for making a model compatible so those can proceed.TestingNo warnings★ 1.3K↓ —
- ase-meta-compatrse/aseSelf-test the LLM's ability to execute ASE's core interpreter machinery (control flow, XML placeholders, regex matching, arithmetic) and report an overall compatibility rating. Use when the user wants to check how well the current model/harness is compatible with ASE, or asks to "test ASE compatibility" or "check ASE compatibility".TestingNo warnings★ 60↓ —
- vapiAnil-matcha/awesome-muse-connectorsManage Vapi voice AI: assistants, phone numbers, calls. Outbound calls are high actuation and need exact-match confirmation; test numbers by default. Trigger phrases: vapi, voice assistant, outbound call, AI phone call.TestingNo warnings★ 1.4K↓ —
- test-case-writingfishzjp/qa-skillsWrite manual test cases (markmap) from docs, bugs or code — code-first: review code for bugs first; extracts machine-readable schema. Not for: requirement-analysis / test-strategy / test-case-review / automation. 从 PRD/API 文档、Bug 或代码写手动用例（markmap）——代码优先：先查代码找 bug 再写，抽 Schema。不用于：需求建模、策略、评审、自动化。TestingNo warnings★ 50↓ —

- build-checkarcasilesgroup/ai-engineeringRun the project's objective quality gates — typecheck, lint, tests, and a production build, whatever this project actually uses — then diagnose any failure down to the file and root cause. Use before committing, opening a PR, or declaring work done, and whenever asked whether the code compiles, typechecks, lints, tests, or builds.TestingNo warnings★ 61↓ —
- ai-test-plannerarcasilesgroup/ai-engineeringPlan and write the tests for a feature, bottom-up. Everything that code or the CLI can verify (pure logic, API endpoints, DB constraints, auth/role rules) is tested without a browser. UI end-to-end tests come last and cover only what the lower layers can't. Use when the user asks to plan tests, write tests, or add test coverage for a feature or checkpoint (e.g. "/ai-test-planner discount rules").TestingNo warnings★ 61↓ —
- ai-orchestratorarcasilesgroup/ai-engineeringBuild a whole feature end-to-end through subagents. It plans gated checkpoints, writes tests and prototypes, then loops each checkpoint through implement → behavior gate (CLI/code tests, UI e2e last) → UI gate (live vs prototype) → adversarial review gate until every checkpoint passes, then hands it to a human to review. Use when the user says "build X", "orchestrate X", "/ai-orchestrator <feature>", or asks to resume an orchestrated feature.TestingNo warnings★ 61↓ —
