- museum-arthuytieu/COG-second-brainSource authentic, high-res PUBLIC-DOMAIN artwork from museum open-access APIs (Met, Cleveland, SMK, Rijksmuseum, NGA, Art Institute of Chicago, Getty, Smithsonian) instead of AI-generated or generic-stock imagery. The default move whenever a visual needs an aesthetic, credible image (blog heroes, decks, social cards, essay/spec figures). Verified keyless recipes + licensing rules inside.MediaNo warnings★ 1.3K↓ —
- no-ai-slophuytieu/COG-second-brainEdit drafts into sharper, more human writing while preserving the writer's personal voice, or detect AI-slop patterns without rewriting. Use when the user wants a draft clearer, more direct, more opinionated, or less AI-sounding, or asks whether writing reads as AI.WritingNo warnings★ 1.3K↓ —
- error-scanhoangsonww/Claude-Code-Agent-MonitorScan recent Claude Code activity for errors and failure signals across all sessions using Agent Monitor data — APIError events and PreToolUse→PostToolUse gaps (tools that started but never completed) — then group failures by tool and model and rank them by frequency. Use when checking for errors or asking "what's failing right now".EngineeringNo warnings★ 1.1K↓ —
- analyze-variantsmicrosoft/power-platform-skillsUse when investigating common or slow variants, repeated work, unusual paths, or a specific Process Mining case.FinanceNo warnings★ 1.1K↓ —
- valid-skillfirst-fluke/oh-my-agentA minimal, fully spec-conformant fixture skill used to exercise the happy path.PlanningNo warnings★ 1.4K↓ —
- verify-login-logoutreticlehq/reticleProve sign-in lands the user where they should be, sign-out really ends the session so a protected page sends them back to sign in, and an expired session asks to sign in again instead of breaking. Use when auth, a login form, a logout button, route guards or token refresh were added or changed, or when a user reports being logged out, or not logged out, unexpectedly.OtherNo warnings★ 1.3K↓ —
- run-historyhoangsonww/Claude-Code-Agent-MonitorInspect CCAM dashboard-run history and relate live run handles to persisted Claude Code or Codex sessions. Use when finding a prior launched task, checking whether a run is still attached, reviewing start/end status, or deciding whether to resume, view, or relaunch work.EngineeringNo warnings★ 1.1K↓ —
- Error Resolverforyourhealth111-pixel/Vibe-SkillsLegacy error-resolution reference archive retained for migration. Do not route user tasks here; use systematic-debugging for active bug, stack-trace, and root-cause work.EngineeringNo warnings★ 3.8K↓ —
- analyze-performance-intakegooseworks-ai/goose-skillsStep of the analyze-performance playbook: gathers the week's numbers from tools, exports and pastes, cleans them, and writes the coverage line or switches to claims-only mode. Run analyze-performance instead; not for direct use.WritingNo warnings★ 1.3K↓ —
- logo-designrampstackco/claude-skillsGenerate logo variants for a brand, producing multiple production-grade marks across different architectures (wordmark, lockup, symbol-only, letterform-as-symbol, monogram) with rationale, application specs, and decision-ready presentation. Distinct from `brand-identity`, which produces the complete system (logo plus color, type, voice, applications). Goes deep on the logo specifically: typographic register, symbol approach, application-context discipline (16px favicon, embroidery, signage, motion), and production specs (SVG-ready, single-color, reverse). Triggers on logo design, design a logo, wordmark, monogram, lockup, mark variants, logo iterations, redesign or refine the logo, logo refresh, letterform-as-symbol, and exploring mark variants for an established brand. Does NOT fire for full brand identity (use `brand-identity`), positioning or strategy (use `brand-discovery`), project-wide creative direction (use `creative-direction`), or one-off illustration.DesignNo warnings★ 1K↓ —
- write-outreach-reply-readergooseworks-ai/goose-skillsStep of the write-outreach playbook: sorts outreach replies by type, matches each to its prospect row, sets that person's status and keeps useful exact words. Run write-outreach instead; not for direct use.WritingNo warnings★ 1.3K↓ —
- model-mixhoangsonww/Claude-Code-Agent-MonitorBreak down Claude Code usage by model family (Opus / Sonnet / Haiku) from the Agent Monitor dashboard — each family's share of tokens, share of cost, and the spots where an expensive model is doing cheap work. Pulls per-model token and cost splits from /api/pricing/cost, current rates from /api/pricing, fleet token totals from /api/analytics, and per-session model assignment from /api/sessions. Use when deciding model routing or whether to downshift work to a cheaper tier.DataNo warnings★ 1.1K↓ —
- render-vo-anchored-motion-listiclegooseworks-ai/goose-skillsAssemble a narrated motion-graphic listicle video ad from a config: a voiceover (cloned or cast, in the chosen tone) reads a numbered list while N animated web-graphic beats in one branded design system (alternating tiles, big numerals, callouts) are rendered frame by frame and timed to the voiceover's words. Optional B-roll windows (a brand clip, an AI clip or a motion graphic) give the eye a break, and captions appear only inside those windows, with the voiceover mixed over a low music bed. Free, deterministic assembly; the voiceover, music and any AI clips come from create-vo-elevenlabs, create-music-elevenlabs and create-video-fal. Use for the vo-anchored-motion-listicle format.MediaNo warnings★ 1.3K↓ —
- cost-reporthoangsonww/Claude-Code-Agent-MonitorProduce a scoped CCAM cost and token report by model, provider, source, and session. Use for spend reviews, model-mix analysis, unpriced usage detection, or export-friendly cost summaries.ProductivityNo warnings★ 1.1K↓ —
- set-app-registration-nativemicrosoft/power-platform-skillsUse when the user wants to discover and verify available Entra ID app registrations, wire one to a Power Apps Wrap mobile app, or create one through the Wrap page and update auth.config.json.OtherNo warnings★ 1.1K↓ —
- research-market-listeninggooseworks-ai/goose-skillsStep of the research-market playbook: the worker brief for listening to what people say about the brand and category, risks first. Run research-market instead; not for direct use.ScienceNo warnings★ 1.3K↓ —
- research-competitors-rival-passgooseworks-ai/goose-skillsStep of the research-competitors playbook: the worker brief for profiling one rival at a capped depth, returning a fixed-shape profile. Run research-competitors instead; not for direct use.ScienceNo warnings★ 1.3K↓ —
- kr-work-reportmohitagw15856/pm-claude-skillsUse when asked 보고서 써 줘, 주간보고 작성해 줘, 개조식으로 정리해 줘, 팀장님께 보고할 내용 정리, 1페이지 보고서, 업무 보고서 양식, or write a Korean business report or weekly report. Produces a Korean workplace report in 개조식 and 두괄식 style: a one-line conclusion, then 현황, 문제점, 대안 비교, 건의사항 and 향후 계획 for a 보고서, or 금주 실적, 차주 계획 and 이슈 및 협조 요청 for a 주간보고, with consistent noun-form endings, numbers and owners, plus a short verbal briefing version.WritingNo warnings★ 1.5K↓ —
- cost-breakdownhoangsonww/Claude-Code-Agent-MonitorBreak down Claude Code costs using the Agent Monitor pricing engine. Shows per-model costs (input, output, cache_read, cache_write at $/Mtok rates), per-session costs, daily trends, and compaction baseline token recovery. Use when analyzing spending, comparing model costs, or planning budgets.PlanningNo warnings★ 1.1K↓ —
- appllama-usageAppllama/appllama-skillsUse the Appllama MCP (mcp.appllama.io) well — research real top-grossing mobile apps, their screens, flows, and UI elements, then build from what you learn. Load when the Appllama MCP is connected and the task involves building a mobile app or screen, researching app design patterns, studying onboarding/paywall/feature flows, improving an existing screen, or whenever an appllama_* / search_apps / list_app_screens tool is available. Covers the tool map, pagination, expiring media, and the full build-from-research playbooks.DesignNo warnings★ 4K↓ —
- endpoint-probehoangsonww/Claude-Code-Agent-MonitorProbes each major Agent Monitor API route — /api/stats, /api/analytics, /api/sessions, /api/pricing/cost, /api/workflows/runs, /api/cc-config/overview — and reports each one's HTTP status, latency, and response shape, flagging which are reachable. Use to verify a dashboard install is wired up correctly.DataNo warnings★ 1.1K↓ —
- closed-loophuytieu/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.DesignNo warnings★ 1.3K↓ —
- audit-ppmpluginmicrosoft/power-platform-skillsStatically audit a built `.ppmplugin` before wrap testing. Checks archive layout, manifest compatibility, bundle consistency, Android DEX integrity and SDK leakage, iOS framework structure, native source-to-receiver alignment, and the PCF composite-key/sendAsync transport contract. Reports CRITICAL, WARNING, and INFO findings with fixes routed to the owning stage; never modifies the archive. Requires `jar`; `dexdump` or `strings` improves DEX inspection. Run after /assemble-ppmplugin or standalone on an existing bundle.TestingNo warnings★ 1.1K↓ —
- transcript-grephoangsonww/Claude-Code-Agent-MonitorSearch a Claude Code session transcript for a string or regex pattern and show every matching message with surrounding context. Reads /api/sessions/:id/transcript and resolves sessions via /api/sessions?limit= from the Agent Monitor dashboard. Use when hunting for a specific message, prompt, tool call, or error inside a session's conversation.PlanningNo warnings★ 1.1K↓ —

From the author
Pick 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.
