Comprehensive USB camera and UVC device analysis for debugging video streaming issues. Use when diagnosing camera connectivity, format negotiation, or control capabilities.
Audit Android app layouts for Material Design 3 compliance, accessibility, edge-to-edge support, and modern best practices. Use for layout reviews, pre-release checks, or establishing baseline quality.
AST-based code search using ast-grep for structural pattern matching. Use when searching for code patterns, refactoring, or performing semantic code analysis across multiple languages.
Code coverage for Rust using LLVM instrumentation with support for multiple output formats and CI integration. Use when measuring test coverage, generating coverage reports, enforcing coverage thresholds, or integrating with codecov/coveralls. Trigger terms: coverage, llvm-cov, code coverage, test coverage, coverage report, codecov, coveralls, branch coverage.
Detect unused dependencies in Rust projects for cleaner Cargo.toml files and faster builds. Use when auditing dependencies, optimizing build times, cleaning up Cargo.toml, or detecting bloat. Trigger terms: unused dependencies, cargo-machete, dependency audit, dependency cleanup, bloat detection, cargo-udeps.
Next-generation test runner for Rust with parallel execution, advanced filtering, and CI integration. Use when running tests, configuring test execution, setting up CI pipelines, or optimizing test performance. Trigger terms: nextest, test runner, parallel tests, test filtering, test performance, flaky tests, CI testing.

Automatic guidance for selecting appropriate test tiers based on change context and scope.
| Tier | Duration | Scope | When to Run |
|---|---|---|---|
| Unit | < 30s | Single function/module | After every code change |
| Integration | < 5min | Component interactions | After feature completion |
| E2E | < 30min | Full user flows | Before commit/PR |
| Change Type | Unit | Integration | E2E |
|---|---|---|---|
| Single function fix | Required | Skip | Skip |
| New feature (1 file) | Required | Required | Skip |
| Multi-file feature | Required | Required | Required |
| Refactoring | Required | Required | Optional |
| API changes | Required | Required | Required |
| UI changes | Required | Optional | Required |
| Bug fix (isolated) | Required | Optional | Skip |
| Database changes | Required | Required | Required |
| Config changes | Required | Required | Optional |
Escalate to Integration when:
Escalate to E2E when:
# Tier 1: Unit (fast feedback)
/test:quick
# Tier 2: Integration (feature completion)
/test:full --coverage
# Tier 3: E2E (pre-commit)
/test:full
Consult test-architecture agent when:
3 flaky tests detected
Consult test-runner agent when:
Consult system-debugging agent when:
1. Run /test:quick
2. If pass: Continue working
3. If fail: Fix immediately
1. Run /test:full --coverage
2. Check coverage targets met
3. If gaps: /test:consult coverage
1. Run /test:full
2. All tiers must pass
3. Review coverage report
1. /test:consult new-feature
2. Write tests (TDD)
3. Run /test:quick during development
4. Run /test:full before PR
