- 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
- 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
- improve-search-visibility-fix-writergooseworks-ai/goose-skillsStep of the improve-search-visibility playbook: turns one ranked fix into paste-ready site copy or code with owner, risk and undo, and writes page briefs. Run improve-search-visibility instead; not for direct use.WritingNo warnings★ 1.3K↓ —
- personal-biomohitagw15856/pm-claude-skillsWrite a professional bio in the three lengths you actually need. Use when asked to write a bio, an 'about me', a speaker/author bio, or a short profile blurb. Produces three ready-to-use versions — a one-liner, a short (~50-word) bio, and a long (~150-word) bio — in a consistent third-person voice, plus a first-person variant.WritingNo warnings★ 1.5K↓ —
- plan-campaign-budget-and-testsgooseworks-ai/goose-skillsStep of the plan-campaign playbook: splits the budget across chosen channels, checks per-channel minimums, and writes the test plan and paid structure. Run plan-campaign instead; not for direct use.TestingNo warnings★ 1.3K↓ —
- rfp-responsemohitagw15856/pm-claude-skillsWrite a compliant, competitive response to an RFP/RFQ/ITT (government or enterprise procurement). Use when responding to a request for proposal, bidding on a tender, or answering a procurement questionnaire. Produces a compliance-matrix-driven response that answers every requirement, wins on evaluation criteria, and reads as low-risk to the buyer — structured to the scoring, not the seller's ego.LegalNo warnings★ 1.5K↓ —
- 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
- 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
- make-static-ads-ad-copygooseworks-ai/goose-skillsStep of make-static-ads: writes the text for each slot the ad's template sets, then the primary texts, headline, description and CTA around the image, from usable facts and customer words. Run make-static-ads instead; not for direct use.MarketingNo warnings★ 1.3K↓ —
- threat-modelmohitagw15856/pm-claude-skillsThreat-model a system or feature to find where it could be attacked, before you build it. Use when asked to threat-model, do a security design review, document security risks, identify attack surface, or apply STRIDE to a design. Produces a structured threat model: assets, trust boundaries and data flows, threats enumerated by category (STRIDE), risk scores, prioritized mitigations, and residual-risk sign-off. Defensive security for systems you own or are authorized to assess.SecurityNo warnings★ 1.5K↓ —
- braindumphuytieu/COG-second-brainQuick capture of raw thoughts with intelligent domain classification and competitive intelligence extractionOtherNo warnings★ 1.3K↓ —Also in 1 other repo
- api-test-planmohitagw15856/pm-claude-skillsPlan tests for an API endpoint or service — functional, negative, and contract. Use when asked to test an API, write API test cases, plan REST/GraphQL endpoint testing, or validate an API contract. Produces an API test plan — per-endpoint cases (status codes, schema, auth, validation, errors), boundary/negative cases, contract checks, and non-functional notes — so the API is verified beyond the happy 200.TestingNo warnings★ 1.5K↓ —
- make-static-ads-find-referencesgooseworks-ai/goose-skillsStep of make-static-ads: picks a template for every ad in its chosen style, after its visual idea and style are set, from the brand's own ads, the GooseWorks library or category leaders, and records what the chosen creativity level keeps from it. Run make-static-ads instead; not for direct use.MarketingNo warnings★ 1.3K↓ —
- async-insteadmohitagw15856/pm-claude-skillsConvert a meeting into async work that actually decides — the doc-plus-deadline format that replaces the room, the comment-window rules, the decision-closure step that async usually fumbles, and the honest test for what still needs synchronous. Use when asked can this meeting be async, replace our status meeting with a doc, run this decision without a call, or async isn't working for us. Produces the conversion design, the async artifact format, the closure protocol, and the still-needs-a-room list.TestingNo warnings★ 1.5K↓ —
- email-marketingkostja94/marketing-skillsWhen the user wants to plan email marketing, EDM, newsletter strategy, or email deliverability. Also use when the user mentions "email marketing," "EDM," "newsletter," "SPF," "DKIM," "DMARC," "email deliverability," "email content strategy," "email campaigns," "newsletter strategy," "email automation," or "cold email." For signup UI, use newsletter-signup-generator.MarketingNo warnings★ 1.1K↓ —
- 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↓ —
- make-static-ads-graphic-requestgooseworks-ai/goose-skillsMakes one simple non-ad brand graphic, such as an email header, social feed or story image, or a blog or link-preview image, in the brand's style with at most a short line of text, after claim and rights checks and a yes to the quote; returns the link and alt text. Not for carousels, decks or print. Use alone when you already have the purpose, placement and exact wording; otherwise run make-static-ads.MarketingNo warnings★ 1.3K↓ —
- relay-80-100-workflowAgentWorkforce/relayUse when writing agent-relay workflows that must fully validate features end-to-end before merging. Covers the 80-to-100 pattern - going beyond "code compiles" to "feature works, tested E2E locally." Includes repair-before-failure validation gates, review-depth fresh-eyes review/fix loops with test hardening, PGlite for in-memory Postgres testing, mock sandbox patterns, test-fix-rerun loops, verify gates after every edit, and the full lifecycle from implementation through passing tests to commit.ProductivityNo 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↓ —
- 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↓ —
- voice-baselinehuytieu/COG-second-brainMeasure your own writing corpus for the words and sentence shapes you over-use, so an agent writing in your voice stops amplifying your tics into a style. Produces a counted baseline file and checks any new draft against it. Use when an agent's drafts start sounding like a caricature of you, before publishing anything written in your voice, or every ten new pieces to re-measure.WritingNo warnings★ 1.3K↓ —
- eulogy-writermohitagw15856/pm-claude-skillsHelp someone write a eulogy — the hardest writing most people ever do, at the worst possible time. Use when someone must speak at a funeral or memorial and doesn't know where to start, or has fragments and no shape. Produces a 3-5 minute eulogy built from their memories in their voice, plus a delivery copy formatted for shaking hands — gentle process, no interrogation, nothing invented.WritingNo warnings★ 1.5K↓ —
- oma-brainstormfirst-fluke/oh-my-agentExplore goals, constraints, and alternative approaches before choosing a design. Use when the user requests ideation or design exploration.PlanningNo warnings★ 1.4K↓ —
