- daily-journalhuytieu/COG-second-brainA passive daily work journal that Claude keeps FOR you so you never have to write it yourself. Append short entries after meaningful work (what was done, what you focused on, artifacts touched) to 01-daily/journal/YYYY-MM-DD.md. Run a guided reflection at night or in the morning. Use when you run /daily-journal, say "log this to my journal", "add to today's journal", "reflect on today/yesterday", or when finishing a meaningful chunk of work in any session.WritingNo warnings★ 1.3K↓ —Also in 1 other repo
- porthashgraph-online/awesome-codex-pluginsMake an existing single-player web game multiplayer in a Homie studio. Reads the game (loop, input, state, camera), grades the port easy, medium, hard or not a fit and says why, adds netplay public rooms (bots in empty seats, join in progress, server rules, predicted movement, rounds), phone touch controls, a stable camera and the big-screen view, proves it with the owner tests (held and alternating directions, real touch on iPhone WebKit and Android Chrome, a late joiner, a departing first player, two fresh browsers finishing a round), then publishes only when requested. Use when someone says "make this multiplayer", "make my game multiplayer on Homie", "port this game to my studio", or points at a single-player web game.TestingNo warnings★ 1.5K↓ —
- planhashgraph-online/awesome-codex-pluginsPlan a game or app with the person before building it — sensible defaults from their request, with an interview only when requested that ends in the game's Game Codex, games/<id>/CODEX.md, drawn as a page in the game's own palette, fonts and art that anyone can read and steer (a Claude artifact where the app has artifacts, else a page in their browser, and a private page on the studio's site), kept true as decisions change, with the build's progress on it. Use for step 4 of a new studio, or when someone says "let's plan my game", "what should my game be", "make a design doc, a game bible or a codex", "show me the plan", or before a big change to a game.PlanningNo warnings★ 1.5K↓ —
- closed-loophuytieu/COG-second-brainRun one task through the V-model verification loop: CP-2 plan → CP-3 build → CP-3v component verify → CP-4 integration verify (full lane) → CP-5 acceptance. The worker never grades its own homework; evidence rows trace back to AC-n. Opt-in: invoke with /closed-loop or by asking for the closed loop, proper verification, or an evidence trail. Ordinary work does not run this.PlanningNo warnings★ 1.3K↓ —Also in 1 other repo
- gamehashgraph-online/awesome-codex-pluginsMake or change a rules-plus-view multiplayer web game inside a Homie studio — the server runs the rules, each browser predicts its own movement and renders the game, strangers meet in public rooms, bots fill empty seats, rounds end and restart — prove it with two browsers finishing a round, and give it an epic landing page (a full-bleed hero from its own footage or art, the pitch, Play, phone / computer / TV, live rooms, how to play, credits). Use when someone in a Homie studio (a folder with studio.json) asks for a new game, a change to a game, a game whose own AI decides (opponents picking tactics, an NPC's reaction, a director's call, a turn's move), or a better page for a game ("make my game's landing page epic").DesignNo warnings★ 1.5K↓ —
- minutes-setupsilverstein/minutesGuided first-time setup for Minutes — download whisper model, create directories, configure audio input. Use when the user says "set up minutes", "install minutes", "first time setup", "configure minutes", "get started with minutes", "how do I start using minutes", or when verify shows missing components.MediaNo warnings★ 1.6K↓ —Also in 1 other repo
- oma-observabilityfirst-fluke/oh-my-agentIntent-based observability + traceability router across layers, boundaries, and signals. Routes to vendor-specific skills via category taxonomy; owns transport tuning, meta-observability, incident forensics. Use for observability, traceability, telemetry, APM, RUM, metrics, logs, traces, profiles, SLO, incident forensics, tracing architecture work.DevOpsNo warnings★ 1.4K↓ —
- sharpenNewhashgraph-online/awesome-codex-pluginsRewrite a draft prompt so it asks for an expert-depth version of the same task (expert moves, raw sources, named methods, an outside check) without widening scope. Returns the rewritten prompt and does not do the task. Use for "/sharpen <prompt>" or "make this prompt better before I send it".ProductivityNo warnings★ 1.5K↓ —
- create-user-storyhuytieu/COG-second-brainCreate user stories with duplicate checking across any project tracker (Linear, GitHub Issues, Jira)OtherNo warnings★ 1.3K↓ —
- domain-architecturekostja94/marketing-skillsWhen the user wants to decide domain structure for multiple products or brands—subfolder vs subdomain vs independent domain. Also use when the user mentions "subfolder vs subdomain," "subdirectory vs subdomain," "multiple products domain," "multiple websites," "brand architecture," "branded house," "house of brands," "where to host product," "domain structure," or "hub-spoke domain." For brand SERP, use multi-domain-brand-seo.PlanningNo warnings★ 1.1K↓ —
- debug-broken-uireticlehq/reticleFind out why something in a running web app does not work, when the console is empty and the code looks correct. Reads the click, the request, the store and the console together and returns the file:line to open. Use when a button does nothing, a form will not submit, data will not load, a page renders blank or stale, a modal will not close, or the user says "it's broken" and the code review says it is fine.DesignNo warnings★ 1.3K↓ —
- taste-skillhuytieu/COG-second-brainAnti-slop frontend skill for landing pages, portfolios, and redesigns. The agent reads the brief, infers the right design direction, and ships interfaces that do not look templated. Real design systems when applicable, audit-first on redesigns, strict pre-flight check.DesignNo warnings★ 1.3K↓ —Also in 1 other repo
- data-formshuytieu/COG-second-brainPick the right way to represent a dataset so a reader gets the finding in three seconds — a catalog of 20+ chart and diagram forms with when-to-use and failure modes, plus the encoding decisions that make any of them readable (takeaway headline, direct labels, kill the axis, highlight-and-mute, show the caveat). Style-agnostic — use with whatever palette or design system the destination already has. Use when charting survey results, benchmark data, usage metrics, or research findings for a post, brief, deck, or report, and whenever the default bar chart feels like it's burying the point.DocumentsNo warnings★ 1.3K↓ —Also in 1 other repo
- discount-marketing-strategykostja94/marketing-skillsWhen the user wants to plan, implement, or optimize discount and promotional pricing strategy. Also use when the user mentions "discount strategy," "promo code," "coupon," "redeem code," "lifetime deal," "LTD," "AppSumo," "Black Friday," "Cyber Monday," "BFCM," "seasonal sale," or "promotional pricing." For pricing page, use pricing-page-generator.MarketingNo warnings★ 1.1K↓ —
- add-mnemonnanocoai/nanoclawAdd persistent graph-based memory via mnemon. Agents recall past context before responding and remember insights after each turn.ProductivityNo warnings★ 31.1K↓ —
- churn-preventionalirezarezvani/claude-skillsUse when designing a cancel flow, save offers, exit surveys or dunning emails, or cutting failed-payment churn. Sizes the revenue at stake with churn_impact_calculator.py first. Health scores and expansion: customer-success-manager.OtherNo warnings★ 29.3K↓ —
- unity-agent-workflowshashgraph-online/awesome-codex-pluginsUse for AI-assisted Unity work that needs live repo discovery, project-derived routing, runtime-owner proof, runtime-visible output hard stops, runtime numeric proof for repeated visible-output failures, state-step guards, multi-agent scope ownership, modular C#/asmdef safety, UI/scene/visual asset gates, data-first content changes, validation, cleanup proof, or durable workflow rules. Best when agents must prove the actual folder/module/scene/prefab/runtime owner before editing, especially runtime UI, generated assets, code graphs, tutorial/state flows, guided selection/action flows, overlay/dim source-bound mistakes, coordinate conversions, focus/highlight/marker/HUD alignment, predictive lead aiming, ballistic trajectories, spatial IoU verification, or repeated "fix still not visible" failures.DesignNo warnings★ 1.5K↓ —

- retrohuytieu/COG-second-brainCP-7 retrospective: audit checkpoints, evidence quality, action items, and harvest candidates. Closes the V-model cycle and feeds the next run. Use via /retro after ship, escalate, or significant session.OtherNo warnings★ 1.3K↓ —Also in 1 other repo
- google-apps-scriptjezweb/claude-skillsBuild Google Apps Script automation for Sheets and Workspace. Custom menus, triggers (onEdit / time-driven / form submit), dialogs, sidebars, email batches, PDF export, external API. Use whenever the user wants to automate a Google Sheet, build a Sheets menu / sidebar / dialog, hit a Sheets row from email or a webhook, schedule a Sheets workflow, or asks 'how do I script this in Sheets'.DocumentsNo warnings★ 1.1K↓ —
- product-ui-tastehuytieu/COG-second-brainAnti-slop skill for PRODUCT UI - dashboards, data tables, forms, multi-step flows, settings, list/detail, app shells. The agent reads the surface, budgets the frame first, and ships dense interfaces that are correct at every edge case (overflow, long labels, empty/error/loading states, i18n expansion, keyboard/a11y). House-system-first; maps to Carbon/Polaris/Atlaskit/Fluent/Primer/Material3/Radix-shadcn/Ant. The counterpart to taste-skill, which owns landing/portfolio/marketing.DesignNo warnings★ 1.3K↓ —
- cloudrun-developmentTencentCloudBase/CloudBase-AI-ToolkitCloudBase Run backend development rules (Function mode/Container mode). Use this skill when deploying backend services that require long connections, multi-language support, custom environments, AI agent development, or migrating existing/GitHub apps that need VPC access to MySQL/PostgreSQL/Redis. Also use when diagnosing CloudRun container deploy failures (deploy_failed, readiness/probe failed, image won't start, docker.io pull loops) or a deploy stuck behind a running deploy task. For stateless HTTP services, prefer HTTP cloud functions.DevOpsNo warnings★ 1.2K↓ —Also in 5 other repos
