- second-brain-quizundefined-ui/second-brain-osGenerate questions from the user's own concept pages so they can find out what they saved but never learned, and compare their answers against what the pages say. Use this skill when the user wants to test themselves, revise, make flashcards from their notes, or asks what they have forgotten. Do NOT use for generic quizzing on a topic the vault does not cover, or for answering a question from the vault.TestingNo warnings★ 1.4K↓ —
- react-doctoramplifthq/openmeldUse when the user requests React Doctor or a React code-health audit, or when a concrete React diagnostic question would benefit from its scan. Not a default step after React changes or before committing.EngineeringNo warnings★ 1.4K↓ —
- oma-scholarUpdatedfirst-fluke/oh-my-agentSearch academic literature and generate, validate, or compare Knows paper sidecars. Use for claim/evidence analysis and literature synthesis.ScienceNo warnings★ 1.4K↓ —Also in 3 other repos
- meeting-transcripthuytieu/COG-second-brainProcess meeting recordings and notes into structured decisions, action items, and team dynamics with intelligent noise filteringProductivityNo warnings★ 1.3K↓ —
- export-open-issueshuytieu/COG-second-brainAudit and export open issues from any project tracker with summary analysis and vault archivalProductivityNo warnings★ 1.3K↓ —
- discovery-eyesmohitagw15856/pm-claude-skillsRead your team's messages the way opposing counsel would in litigation discovery — prevention training that makes communication hygiene visceral. Use when asked how would our Slack look in discovery, train my team on communication hygiene, review this thread like a plaintiff's lawyer, or what shouldn't we put in writing. Produces the highlighted-exhibit reading of sample messages, the patterns that create legal risk, and a debrief with the write-it-this-way rules — strictly for prevention, never for concealment.LegalNo warnings★ 1.5K↓ —
- the-pragmatic-programmerciembor/agent-rules-booksApply Hunt and Thomas-inspired pragmatic programming rules when improving engineering judgment, feedback loops, DRY knowledge, orthogonality, automation, or adaptability.OtherNo warnings★ 3.2K↓ —
- writing-testsamplifthq/openmeldGates whether a new test should exist and forces it to be efficient, protecting CI from low-value test bloat. Use before any change to what a pytest, Jest, or Playwright test asserts or sets up, down to one fixture or one assertion added to an existing block. Front-loads the value bar (every test must catch a realistic regression no existing test already catches; extend the nearest existing test before writing a new standalone one; test behavior through the public interface, not implementation details; collapse near-duplicates into parameterized cases) and the efficiency bar (deterministic, isolated, fast; pick the cheapest test level; Django TestCase over TransactionTestCase; no sleeps, no real network; no time bombs from absolute dates left to age against the real clock; no database a test never uses). Includes a "don't write it" decision tree. For fixing an existing flaky test use `/fixing-flaky-tests`; after this gate says a Playwright test is warranted, use `/playwright-test` for mechanics.TestingNo warnings★ 1.4K↓ —
- refactoring-guruciembor/agent-rules-booksApply Refactoring.Guru-inspired rules when diagnosing code smells, choosing refactoring techniques, and stopping cleanup before uncontrolled redesign.EngineeringNo warnings★ 3.2K↓ —
- second-brain-mergeundefined-ui/second-brain-osMerge two pages that describe the same thing, preserving every distinct claim, redirecting inbound links, and recording the merge. Use this skill when the user approves a duplicate merge, says "these are the same page", "merge X into Y", or asks to clean up near-duplicates that a lint run proposed. Do NOT use to merge pages on your own judgement, to delete a page outright, or to split one page into several.OtherNo warnings★ 1.4K↓ —
- health-checkhoangsonww/Claude-Code-Agent-MonitorRun comprehensive health checks on the Claude Code Agent Monitor system. Validates dashboard API, database, WebSocket, hooks, and disk usage. Use to verify the monitoring setup is working correctly.DataNo warnings★ 1.1K↓ —
