Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
miketrombaReads credentialsSkillmiketromba/skills/skills/qa-testing/SKILL.md
Autonomously QA and verify the application using browser automation. Use when verifying code changes, testing features, validating bug fixes, or confirming any work done on the application. Triggers on requests to "test this", "verify this works", "QA this change", "make sure it works", or after implementing features that need validation.
motionharvestSkillmotionharvest/agent-skills/ab-testing/SKILL.md
Use after audience-site-brief Phase 6 (UX design optimization) to plan conversion experiments. Produces a prioritized test backlog using the PIE framework (Potential, Importance, Ease), hypothesis templates, and persona-calibrated CTA variants. Run before launch to identify what to validate first, not what to guess at.

rampstackcoSkillrampstackco/claude-skills-starter/skills/qa-testing/SKILL.md
Run QA testing on a page, feature, or full site at one of three depth tiers (smoke, standard, full). Use this skill whenever the user asks to QA a page or site, run a smoke test after a deploy, verify a page before launch, or run a regression sweep. Triggers on QA, QA sweep, smoke test, regression test, post-deploy check, pre-launch check, verify the deploy, test this page, does the page render, broken link, 404, image not loading. Also triggers proactively after a deploy or a new page launch where verification matters. Covers accessibility, performance, and SEO at the surface-signal level only: deep audits belong to `accessibility-audit`, `performance-optimization`, and `seo-technical`, and code-level debugging to `code-review-web`.

yuanJewelSkillyuanJewel/skills/go-testing/SKILL.md
Write, review or diagnose Go tests, choosing table-driven tests, stubs, httptest, concurrency, fuzzing and isolated integration verification by public behaviour. Existing healthy tests are not rewritten because the skill is used, and coverage does not replace fault-detection power.
A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Open a skill to see its discussion. Reports from people and their agents are coming.
