Verify an external or AI-generated security report against the actual codebase before acting on it. Use when handed a scanner PDF, automated teardown, audit report, or bug-bounty submission — classifies every finding CONFIRMED / OVERSTATED / FALSE-POSITIVE / FABRICATED and salvages the real work items.
Creates GitHub Actions for the Marketplace. Use when scaffolding a new action, implementing composite steps, writing BATS tests, or preparing a Marketplace release.
Audit documentation against its declared hierarchy — broken links, duplicates, misplaced content, stale references, single-source-of-truth enforcement. Use for doc health reviews.
Audit README.md files against best practices for repos, accounts, or orgs. Detects missing sections, stale links, inconsistent formatting, and convention violations. Use when reviewing README quality across one or many repos.
Generate or update README.md files across three scopes — repo (with project-type detection), account (GitHub user profile), and org (organization profile). Use when creating, updating, or aligning a README to org conventions.
Audits website accessibility for WCAG 2.2 AA compliance, generating findings and code fixes. Use when reviewing accessibility, keyboard navigation, screen reader compatibility, or inclusive design.

Target: $ARGUMENTS
Writes focused, behavior-driven tests following project testing strategy.
TDD methodology (language-agnostic): See tdd-core plugin (testing-tdd skill)
Python-specific documentation: references/
references/testing-strategy.md - Python tools (pytest, Hypothesis, inline-snapshot)references/tdd-best-practices.md - Python TDD examples (extends tdd-core)TDD only: pytest for known cases, Hypothesis for edge cases, inline-snapshot for regression. Tests assert observable behavior — inputs produce expected outputs/side-effects. No Gherkin, no feature files, no step definitions.
See references/testing-strategy.md for tool selection guide.
Cycle: RED (failing test) → GREEN (minimal pass) → REFACTOR (clean up)
Structure: Arrange-Act-Assert (AAA)
def test_order_processor_calculates_total():
# ARRANGE
items = [Item(price=10.00, qty=2), Item(price=5.00, qty=1)]

# ACT
total = processor.calculate_total(items)
# ASSERT
assert total == 25.00
| Priority | Area | Example |
|---|---|---|
| CRITICAL | Math formulas | Scores always in bounds |
| CRITICAL | Loop termination | Never hangs |
| HIGH | Input validation | Handles any text |
| HIGH | Serialization | Always valid JSON |
High-Value: Business logic, integration points, edge cases, contracts
Avoid: Library behavior, trivial assertions, implementation details, default constants, stale fixture patches (see references/testing-strategy.md → "Patterns to Remove")
