Mechanism

When It Triggers · How It Works · What It Produces

Breaks down how the skill works and what it produces, so you can quickly judge whether it fits your scenario and value.

Trigger

When tests fail, builds break, or behavior doesn't match expectations
When any unexpected error occurs

Mechanism

Five-step triage: reproduce → localize → reduce → fix → guard
Stop-the-line rule: don't fix before identifying root cause
Binary search localization: narrow problem scope quickly
Test reduction: simplify complex scenarios to minimal reproducible cases
Guard measures: add regression tests, monitoring alerts after fix

Outcome

Root cause analysis report, verifiable fix, regression tests, and guard measures

Use Cases

Two Typical Use Cases

Scenario 01

Production Emergency Troubleshooting

When production failures occur, the agent uses this skill to quickly reproduce and localize the root cause. The "stop-the-line" rule prevents guesswork, systematically narrowing the problem scope, proposing verifiable fixes, and adding guard measures.

Scenario 02

Test Failure Root Cause Analysis

When tests fail in CI, the agent uses this skill to analyze the failure, reproduce the scenario, localize to specific lines via bisection or reduction, fix, and add regression tests to prevent re-breaking.

You May Also Need These Skills

api-and-interface-design

Guides agents to design stable, hard-to-misuse public interfaces using contract-first principles. Covers REST, GraphQL, module boundaries, component props, emphasizing Hyrum's Law, One-Version Rule, error semantics, and boundary validation. Produces consistent, maintainable, well-documented interface specifications.

Workflow

browser-testing-with-devtools

Browser testing skill that gives agents live browser runtime visibility via Chrome DevTools MCP. Supports DOM inspection, console log capture, network request analysis, performance profiling, and visual output verification. Bridges the gap between static code analysis and live browser execution.

CLI Manual

ci-cd-and-automation

CI/CD automation skill that guides agents to set up and maintain automated build and deployment pipelines. Emphasizes shifting quality gates left, integrating tests, lint, type checking, and build verification into every change. Follows the "smaller is faster is safer" principle with frequent small releases.

Workflow

code-review-and-quality

Code review and quality skill that guides agents to conduct multi-axis code reviews covering correctness, design, maintainability, security, and performance. Emphasizes change sizing (~100 lines), severity labels (Nit/Optional/FYI), and splitting strategies to ensure code quality before every merge.
