Use whenever the user asks to write tests (before or after the code), mock a dependency or raise coverage.TestingNo warnings★ 29.3K↓ —
- openmeld-changelogamplifthq/openmeldUse when deciding whether an OpenMeld change needs a Changelog entry, writing or publishing an entry, preparing release notes, validating Changelog projections, or historically backfilling missing changes.WritingNo warnings★ 1.4K↓ —
- oma-imageNewfirst-fluke/oh-my-agentGenerate raster images or reference-guided variations through the OMA image CLI. Use for image assets or explicit vendor comparisons; pixel editing uses an editor.MediaNo warnings★ 1.4K↓ —
- youtube-video-kithuytieu/COG-second-brainSelf-evolving second brain with 35 AI skills, 10 agents, and people CRM. Closed-loop harness: a V-model verification lifecycle where the worker never grades its own homework. Plus paired anti-slop design skills for marketing and product UI. Works with Claude Code, Cursor, Kiro, Gemini CLI, Codex.MediaNo warnings★ 1.3K↓ —
- 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
- 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
- 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
- form-croalirezarezvani/claude-skillsUse when a lead, contact, demo or checkout form is underperforming or being designed, before changing fields. Scores field friction with form_field_analyzer.py. Signup forms: signup-flow-cro.MarketingNo warnings★ 29.3K↓ —
- anti-ui-slophashgraph-online/awesome-codex-pluginsStop coding agents from shipping generic UI. Use UIZZE's 800,000+ real web and iOS screens to build product-specific interfaces, define a design contract, cover required states, and run a hard finish gate. Use when designing, implementing, redesigning, critiquing, or pre-ship reviewing a web or iOS interface in Codex, Claude Code, Cursor, Copilot, or another coding agent. Trigger with "anti-ui-slop", "stop UI slop", "ground this UI in real screens", or "run the UI finish gate".DesignNo warnings★ 1.5K↓ —Also in 8 other repos

- ai-tool-pickermohitagw15856/pm-claude-skillsFigure out which AI tool actually fits the task in front of you — chatbot, coding assistant, image model, agent, or none — instead of forcing one tool onto everything. Use when asked which AI tool should I use for, what's the best AI for, do I even need AI for this, or should I use ChatGPT or something else. Produces a match between your task and the right kind of AI tool (with why), the trade-offs that matter for your case, when the answer is a non-AI tool or plain human effort, and how to try it cheaply before committing — so you pick by fit, not by hype or habit.MediaNo warnings★ 1.5K↓ —

- loop-engineeringhuytieu/COG-second-brainShared loop-engineering reference for COG skills - the agent loop, deterministic verifiers, termination conditions, in-loop context management, and named patterns.

- trip-plannermohitagw15856/pm-claude-skillsTurn a destination, some dates, and your vibe into a realistic day-by-day trip itinerary — paced for real humans, with a packing list and a rough budget. Use when asked to plan a trip, build a travel itinerary, what should I do in [place], or help me plan my holiday. Produces a day-by-day plan grouped by area (so you're not criss-crossing the city), must-book-ahead flags, a packing list tuned to the trip, a rough budget range, and honest notes on pace and gaps to fill with local info.PlanningNo warnings★ 1.5K↓ —

- blog-publishhuytieu/COG-second-brainWrite and publish a post to your own static blog end to end: content checklist (embedded links, optional TL;DR), per-post ASCII art, an agent-readable markdown twin, deploy, and social distribution.

- responsiveness-checkjezweb/claude-skillsTest website responsiveness across viewport widths using browser automation.

- regulator-eyesmohitagw15856/pm-claude-skillsRead your marketing claims, landing page, or ad copy the way a consumer-protection investigator would (FTC/ASA framing) and draft the inquiry letter they could send. Use when asked to check my marketing claims, read this like a regulator, audit my landing page for claim risk, or is this ad compliant. Produces a claim inventory with substantiation demands, the inquiry letter, and a fix-or-drop debrief per claim.LegalNo warnings★ 1.5K↓ —
