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.
appsmithorgSkillappsmithorg/appsmith/.agents/skills/fix-pw-spec/SKILL.md
Fix a failing Playwright spec by analyzing error output, identifying the root cause in the test code, and applying corrections. Use when a Playwright test fails due to wrong selectors, bad waits, incorrect assertions, or code errors. Trigger phrases: "fix this playwright test", "this spec is failing", "playwright test broken", "fix the flaky test".

PostHogSkillPostHog/posthog/.agents/skills/extending-personhog-test-harness/SKILL.md
When and how to add scenarios, chaos events, and invariants to the personhog e2e test harness (rust/personhog-test-harness). Use after fixing a bug or regression in the personhog leader path (leader, router, writer, replica, coordination protocol) so the fix gets a permanent regression scenario; when adding a new failure mode to test (crashes, drains, zombies, lag, failover); or when a new correctness property needs asserting during runs. Trigger terms: personhog gate, chaos scenario, test harness, leader path regression, handoff bug, eviction, writer lag, acked write.

comet-mlSkillcomet-ml/opik/.agents/skills/explore-feature/SKILL.md
Use when a developer wants an e2e test covering a change they just made — e.g. "explore this feature", "add a test for my PR", "cover the feature in PR #7303", "test my branch". Reads a ticket + changed code to work out the one flow worth covering, then delegates authoring to writing-e2e-tests, which writes a normal tiered spec under tests/<area>/.

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.
