slopgate-test-extender

vasceannie/slopgate/.claude/skills/slopgate-test-extender/SKILL.md

Extend Python test suites with parametrization, fixture reuse, and quality enforcement. Use when asked to add tests, extend existing tests, improve test coverage, consolidate duplicate tests, fix test quality issues, or when Slopgate reports untested-production-code, missing test references, or coverage gaps. Triggers on requests like "add tests for X", "extend these tests", "parametrize tests", "consolidate tests", "fix test quality", "improve test coverage", "write tests for this function", "test this module", "behavior tests", "integration tests", "missing tests", "coverage holes", "untested code", or when a hook denies with test-related findings.

osteelSkill

test-audit

osteel/agent-skills/test-audit/SKILL.md

Audit the existing test suite for structural and quality issues — wrong-layer tests, redundant browser tests, infrastructure overuse, flaky/unreliable patterns, rotted skipped tests, unclear test names, dataset opportunities, duplicate tests, folder drift — then fix the approved issues. Use when the user says things like "audit the tests", "review the test suite", "our tests are slow", "our tests are flaky", "improve test distribution", "too many end-to-end tests", "tests are taking too long", "are our tests in the right layer", or "clean up the test suite". Also invoke proactively after a major feature milestone when the suite has grown significantly. Distinct from `cover` (which adds tests for recent code changes) — this skill audits what's already there and never adds net-new tests for uncovered code. Use the `test` skill to run the suite during the baseline and verification phases.

devpilotXSkill

test-strategy

devpilotX/skills/skills/test-strategy/SKILL.md

Decide what deserves a test and write tests that fail for the right reason. Use when the user asks what or how to test, asks about unit, integration or end to end tests, test coverage, mocking, fixtures, flaky tests, test driven development, snapshot tests or contract tests, asks why their tests pass while production breaks, or asks how to add tests to code that has none. Allocates effort by what a failure costs rather than by a coverage target, tests behaviour instead of implementation so refactoring does not break the suite, makes flakiness a defect rather than a retry, and states plainly that coverage percentage measures execution rather than correctness. Triggers on what should I test, how do I test, unit tests, integration tests, end to end tests, test coverage, mocking, flaky tests, TDD, snapshot tests, my tests pass but production breaks, add tests to legacy code.

saikumaryerraSkill

regression-testing-agent

saikumaryerra/AutoCodeReview/.claude/skills/regression-testing-agent/SKILL.md

Design test strategies, generate test cases, analyze test results, and manage regression testing. Use this skill when the user mentions test plans, test cases, regression testing, test coverage, QA, smoke tests, integration tests, E2E tests, test automation, bug triage, or asks "what should we test", "write test cases for this feature", or "analyze these test results". Also triggers for impact analysis ("what could this change break"), flaky test investigation, test data generation, test strategy design, test automation frameworks, coverage analysis, or any request about ensuring software quality through testing. Even casual questions like "did we test enough" or "what's risky about this release" should activate this skill.

CLAUDE.md vs AGENTS.md

Agent instruction files

What are agent instruction files?

Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.

CLAUDE.md or AGENTS.md?

CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.

What is a skill?

A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.

Can I search my own team's files too?

Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
