- second-brain-queryundefined-ui/second-brain-osAnswer a question from a second-brain vault by reading its own pages, citing the pages used, and saying plainly when the vault does not contain the answer. Use this skill whenever the user asks what they know about a topic, what they have read on something, what connects two ideas, what they have changed their mind about, or asks any question that should be answered from their own notes rather than general knowledge. Do NOT use for ingesting new material, for general questions the vault has nothing to do with, or when the user explicitly wants an answer from the open web.ProductivityNo warnings★ 1.2K↓ —
- refactor-cleandzhng/skillsRefactor cleanly instead of layering sediment. Use for rename requests, stale or misleading names, legacy leftovers, changed scope, or when a change reveals duplicated concepts, local adapters, obsolete owners, redundant inputs or guards, compatibility wrappers, parallel abstractions, an over-large module that has accreted many responsibilities, or "just tack this on" pressure in any code area.EngineeringNo warnings★ 1.4K↓ —
- 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★ 1.2K↓ —
- report-issuemicrosoft/power-platform-skillsUse this skill when the user wants to "report a bug", "file an issue", "report an issue", "submit a bug report", or report any problem with the code-apps plugin to the GitHub repository.EngineeringNo warnings★ 1.1K↓ —
- helphashgraph-online/awesome-codex-pluginsShow KERNEL help. The unified skill system, state operations, agents, current plugin status. Triggers: help, how, what, skills, commands.OtherNo warnings★ 1.5K↓ —
- design-fixhashgraph-online/awesome-codex-pluginsCompare one already-implemented screen or component against its Figma source and fix the deviations you pick -- reads the node live through the figma-bridge MCP, or from the Node Specs of an existing /design plan, then diffs box, layout, typography, fill, stroke, radius, effects, and content against the code that renders it. Reports first, fixes only what you select, and never touches Figma.DesignNo warnings★ 1.5K↓ —
- minutes-tagsilverstein/minutesLightweight outcome tagging for meetings — won, lost, stalled, great, or noise. Use whenever the user says "tag this meeting", "mark that as a win", "that one was a loss", "tag yesterday's call as stalled", "mark this great", "that meeting was noise", "label that meeting", or any time they describe a meeting outcome in passing. Tagging takes 5 seconds and unlocks /minutes-mirror correlation analysis — the more meetings get tagged, the smarter mirror gets at telling the user what behavior patterns lead to wins. Surface this skill any time the user mentions a meeting result, win, loss, or wasted time.OtherNo warnings★ 1.6K↓ —Also in 1 other repo
- 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↓ —
- using-agent-relayAgentWorkforce/relayUse when you are a registered relay agent (a spawned worker, or a lead that called register_agent) coordinating with peers in real time over current Agent Relay MCP tools - messaging, channels, threads, reactions, search, inbox, actions, and worker spawn/release. For role selection and orchestrator startup instructions, use https://agentrelay.com/skill and the orchestrating-agent-relay skill.OtherNo warnings★ 1.1K↓ —
- 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↓ —
- oma-debugfirst-fluke/oh-my-agentBug diagnosis and fixing specialist - analyzes errors, identifies root causes, provides fixes, and writes regression tests. Use for bug, debug, error, crash, traceback, exception, and regression work.EngineeringNo warnings★ 1.4K↓ —
- writing-guidelinesfcakyon/claude-codex-settingsThis skill should be used when the user asks to "review writing", "check documentation style", "audit interface copy", or "apply writing guidelines".WritingNo warnings★ 1.2K↓ —
- mono-coloryanliudesign/mono-color-skillGenerate original one-ink or controlled two-ink editorial images from any theme, sentence, article idea, object, or reference photo. Always use this skill when the user asks for 单色海报、双色印刷、单色调视觉、蓝色/绿色孔版印刷、risograph、网点照片、复古或当代编辑排版、zine poster, monochrome editorial poster, duotone print, or asks to use the mono-color style. It uses an adaptive white, gray, or pale-beige substrate, no more than two printing inks, active negative space, terse human language, and strong serif/grotesk/mono typography without making retro styling the default or copying a source composition, wording, logo, or artwork. Produce both the final generation prompt and the generated raster image unless the user explicitly asks for prompt only.DesignNo warnings★ 3.6K↓ —
- soap-notemohitagw15856/pm-claude-skillsStructure a clinical encounter into a clean SOAP note. Use when asked to write a SOAP note, document a patient encounter, turn visit notes into clinical documentation, or structure subjective/objective/assessment/plan. Produces a well-organised SOAP note — Subjective, Objective, Assessment (with differential), and Plan — from the provided encounter details, in standard clinical-documentation style.ProductivityNo warnings★ 1.5K↓ —
- python-guidelinesfcakyon/claude-codex-settingsThis skill should be used when writing, reviewing, or refactoring Python code. Covers code integration, idiomatic patterns, docstring formatting, anti-abstraction rules, and software engineering basics.EngineeringNo warnings★ 1.2K↓ —
- second-brain-transcriptundefined-ui/second-brain-osClean a raw transcript before ingestion: punctuate, paragraph, label speakers, fix mistranscribed technical terms, and split long recordings by topic. Use this skill when the user drops an auto-generated transcript, subtitle file, podcast or lecture transcript, meeting recording text, or asks to process a video or audio source. Do NOT use for text that is already prose, for summarising a transcript, or for the ingestion itself.MediaNo warnings★ 1.2K↓ —
- openmeld-cliamplifthq/openmeldOfficial public OpenMeld Skill for agents using the `openmeld` CLI to consult the Center Agent, set up OpenMeld, connect local agents, create or request Agent Profiles, work in Organizations and Spaces, observe or stop Wakes, trace delivery, and repair local state.EngineeringNo warnings★ 1.4K↓ —

- release-commshuytieu/COG-second-brainRelease communication pipeline for your product: turn a deployment runsheet and a GitHub milestone into a customer-facing release note with real screenshots and videos, docs updates (including retrofits of articles the release makes stale), a Slack announcement draft, and a lightweight marketing package. Use when you say "cover today's release", "write the release note", or "/release-comms".DevOpsNo warnings★ 1.3K↓ —Also in 1 other repo
- terminal-replicahuytieu/COG-second-brainReproduce YOUR real terminal and CLI agents (Claude Code, Codex CLI, Gemini CLI) faithfully in any generated graphic, GIF, or video frame. Use whenever an asset shows a terminal, an agent transcript, a statusline, or a CLI banner. Capture your actual theme, font, prompt and statusline first, and never invent a generic "hacker terminal" look.MediaNo warnings★ 1.3K↓ —Also in 1 other repo
