Testing

Combined codebase health dashboard that scores a project across all four quality dimensions — PR quality, architecture, tech debt, and test quality — in a…

Full-sweep mode: runs a unified analysis across all quality dimensions — code decay, architecture, tech debt, and test quality — then applies fixes directly…

Test quality review drawing on twelve classic engineering books — with primary focus on xUnit Test Patterns, The Art of Unit Testing, How Google Tests…

Use when defining ambiguous or high-complexity new features, product behavior, UI/component design, architecture choices, contract changes, or when…

Audit whether tests earn their maintenance cost and which suite owns each contract.

Write tests that pin real behavior instead of implementation details, config values, or lucky samples.

Fast genomic interval operations (overlap, nearest, merge, coverage, cluster, complement, subtract, count-overlaps), multi-format bioinformatics I/O…

Analyze A/B test results with statistical significance, sample size validation, confidence intervals, and ship/extend/stop recommendations.

Design experiments to test assumptions for an existing product — prototypes, A/B tests, spikes, and other low-effort validation methods.

Design lean startup experiments (pretotypes) for a new product.

Identify risky assumptions for a feature idea in an existing product across Value, Usability, Viability, and Feasibility.

Create a structured customer interview script with JTBD probing questions, warm-up, core exploration, and wrap-up sections.

Generate a Lean Canvas with problem, solution, metrics, cost structure, UVP, unfair advantage, channels, segments, and revenue.

Run a pre-mortem risk analysis on a PRD or launch plan.

Prioritize assumptions using an Impact × Risk matrix and suggest experiments for each.

The durable documentation set that makes an AI-built (vibe-coded) app reviewable before shipping.

Red-team a PRD, roadmap, or strategy by attacking its load-bearing assumptions before reality does.

Use when encountering a bug, test failure, or unexpected behavior, before proposing fixes

Use for PUA/try-harder productivity coaching when the user expresses frustration, repeated failure, quality complaint, passive behavior, says retry/change…
