Human review protocol for whether AI output is grounded in its sources: claim-by-claim attribution, hallucination classes, citation verification, sampling that is defensible, and a recorded attestation because groundedness cannot be fully automated. Also covers the responsible-AI pass - harmful output, bias…

Skill Claude Code

Sets up and maintains visual regression testing: what to snapshot, baseline strategy, masking dynamic regions, threshold tuning, containerized baselines, and the review-and-update workflow. Use when styling regressions escape to production, when snapshots fail on every machine or every run, when baselines are being…

Skill Claude Code

Classifies a diff into file tags and hunk tags - new public export, new endpoint, modified auth, SQL string, migration, added dependency, touched prompt - then maps each tag to the quality practices it makes relevant, producing a defensible per-change check scope instead of running everything or guessing. Use when…

Skill Claude Code

Creates, reviews, and modernizes static code analysis setups for Node.js and TypeScript repositories, covering ESLint flat config, typescript-eslint, tsconfig, Prettier, import sorting, Husky, lint-staged, package.json quality scripts, and CI quality gates. Use when setting up or auditing linting, formatting…

Skill Claude Code

Analyzes technical debt in codebases, test suites, architecture, dependencies, and delivery workflows using observable signals. Use when auditing repository health, explaining slow delivery or flaky tests, prioritizing refactoring, or building an evidence-based remediation roadmap with risk, effort, and ROI. Use when…

Skill Claude Code

Runs the red-green-refactor loop with a compact set of rules: one failing test, the minimal code to pass it, cleanup under green. Use for routine test-first work on a single behavior or a small bug fix, and when the request mentions TDD, test-first, red-green-refactor, or writing the test before the code. For…

Skill Claude Code

Drives implementation test-first through red-green-refactor cycles: one failing test, the minimal code to pass it, then cleanup under green. Use before writing production code for a new behavior, and whenever the request mentions TDD, test-driven, test-first, red-green-refactor, "write the test first", "start with a…

Skill Claude Code

Tests the customization assets themselves - skills, prompts, custom agents, instructions - the way a product is tested: activation cases that check an asset fires when it should and stays quiet when it should not, output-contract cases, safety cases, collision cases between assets competing for the same trigger, a…

Skill Claude Code

Validates API responses against OpenAPI or JSON Schema, detects breaking changes between spec versions, and builds consumer-driven contract checks. Use when an API has a published spec, when a backend change might break a client, when API tests assert only status codes, or when mocked fixtures need a guard against…

Skill Claude Code

Applies OWASP-informed security testing within a tester scope: an authorization gate before any probing, authorization matrices, broken access control and IDOR checks, input validation and injection observation, session and auth behaviour, and safe reporting of findings. Use when testing auth-protected features, when…

Skill Claude Code

Builds an offline eval suite for LLM-powered features: golden reference cases per prompt template, deterministic scoring where possible, a regression gate on prompt, model and retrieval changes, and CI wiring with promptfoo, Vitest or deepeval. Use when a product ships prompts, agents or RAG, when a model or prompt…

jaktestowac/awesome-copilot-for-testers

Skill Claude Code

Tests the runtime validation around model output - schema conformance, PII leakage, moderation, refusal behaviour, tool-call safety - and the adversarial suite that tries to defeat it: direct prompt injection, jailbreaks, and indirect injection through retrieved documents, tool results and user content. Use when an…

Skill Claude Code

Designs and runs performance and load tests: workload modelling from real traffic, thresholds tied to SLOs, warmup and ramp shapes, percentile-based analysis, and lightweight CI perf checks with k6 or Artillery. Use when a feature has latency or throughput requirements, when "it feels slow" needs to become a number…

jaktestowac/awesome-copilot-for-testers

Skill Claude Code

Builds and maintains bidirectional traceability between requirements and the tests that verify them: extracts a matrix from an existing codebase, annotates tests with requirement IDs, finds orphan tests and uncovered requirements, verifies that each link is real, and enforces linkage in CI. Use when a suite exists but…

jaktestowac/awesome-copilot-for-testers

Skill Claude Code

Turns point-in-time quality readings into a trend: archives each run, diffs against the previous one, and reports direction per metric - practices newly present or regressed, coverage movement, flake rate, waivers expiring, eval scores - using limit/current/goal framing. Use when quality reporting is a series of…

Skill Claude Code

Cuts AI tells from what the agent says about its own work: completion claimed without a run, invented file paths and API names, terminal output that was never produced, findings with no location, percentages with no denominator, absence claimed from one grep, effort narration instead of results, hedge stacking, buried…

jaktestowac/awesome-copilot-for-testers

Skill Claude Code

Cuts AI tells from test code: tests that pass without proving anything, tautological assertions, mock-only tests, hardcoded waits, coverage theater, vague names, swallowed errors, retries used as fixes. Use whenever test code is written, changed, or reviewed, including tests produced as a side effect of a feature…

Skill Claude Code

Compares implementation evidence against acceptance criteria and shows what is met, partial, missing, or untestable. Use when checking feature readiness, preparing QA sign-off, or turning criteria into a concrete verification matrix without inventing missing behavior.

jaktestowac/awesome-copilot-for-testers

Skill Claude Code

Verifies that the lines and branches a change actually touched are executed by tests, using LCOV or Cobertura diff coverage instead of whole-repo percentages, and escalates uncovered high-risk changes into a blocking finding. Use when a pull request needs a coverage gate that unrelated tests cannot satisfy, when total…

Skill Claude Code

Writes a few solid unit tests, using a compact set of rules for structure, assertions, determinism, and edge cases. Use for routine everyday testing of a single function, class, or small module, or for a quick sanity check on tests someone just wrote. For legacy backfills, flaky-suite investigations, deep test-double…

jaktestowac/awesome-copilot-for-testers

Skill Claude Code

Writes and reviews focused, deterministic unit tests that verify behavior through public interfaces instead of implementation details. Use whenever tests are added to code that already exists, and when the request mentions unit tests, test coverage, edge cases, mocks or test doubles, "add tests for this function"…
