The instruction itself

3 sections, as written by the author

Dev Testing

Run testing work for configured AI docs features. Before changing docs or code, propose the concrete plan for this phase and wait for user approval unless the user already approved the exact phase plan.

Phase Contract

Run npx ai-devkit@latest lint before phase work.
If working on a named feature, run npx ai-devkit@latest lint --feature <name>.
Read the testing doc, requirements, design, implementation notes, and current diff before changes.
Apply the verify skill before making coverage or test-pass claims.
If parent dev-lifecycle established usable task tracing, emit testing phase, next-action, and evidence events per task.

Write Tests

Use for Phase 8.

Run npx ai-devkit@latest lint --feature <name> and reference the testing doc path it validates. If manual path resolution is unavoidable, first resolve .ai-devkit.json paths.docs, falling back to docs/ai.
Gather context: feature name, changes summary, environment, existing test suites, flaky tests to avoid.
Analyze the testing template, success criteria, edge cases, available mocks, and fixtures.
Add unit tests for happy paths, edge cases, and error handling for each module. Highlight missing branches.
Add integration tests for critical cross-component flows, setup/teardown, and boundary/failure cases.
Run coverage tooling, identify gaps, and suggest additional tests if below the target.
If task tracing is available, record evidence for each fresh test/coverage command per task.
Update the selected testing doc with test file links and results.

Next: dev-review. If tests reveal design flaws, return to dev-design.

Verification Before Completion

by ZhanlinCui

×6

Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always

Expert guidance for systematic backtesting of trading strategies. Use when developing, testing, stress-testing, or validating quantitative trading strategies. Covers "beating ideas to death" methodology, parameter robustness testing, slippage modeling, bias prevention, and interpreting backtest results. Applicable when user asks about backtesting, strategy validation, robustness testing, avoiding overfitting, or systematic trading development.

Cloud laboratory platform for automated protein testing and validation. Use when designing proteins and needing experimental validation including binding assays, expression testing, thermostability measurements, enzyme activity assays, or protein sequence optimization. Also use for submitting experiments via API, tracking experiment status, downloading results, optimizing protein sequences for better expression using computational tools (NetSolP, SoluProt, SolubleMPNN, ESM), or managing protein design workflows with wet-lab validation.

This skill should be used for time series machine learning tasks including classification, regression, clustering, forecasting, anomaly detection, segmentation, and similarity search. Use when working with temporal data, sequential patterns, or time-indexed observations requiring specialized algorithms beyond standard ML approaches. Particularly suited for univariate and multivariate time series analysis with scikit-learn compatible APIs.

Copy the folder

Take codeaholicguy/dev-testing from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
