- clean-user-facing-textguillaumemeyer/watermarks-removerClean and finalize authorized natural-language text intended for readers by auditing suspicious invisible Unicode and rewriting prose while preserving facts, meaning, and the writer's voice. Use when the user asks to clean, humanize, polish, or finalize articles, manuscripts, reports, documentation, emails, product copy, UI text, Markdown, or HTML prose, or when a project rule or instruction file explicitly requires this workflow. Don't use for code-only tasks or undisclosed authorship evasion; leave code, commands, identifiers, paths, APIs, formulas, citations, required disclosures, and verbatim quotations unchanged.DesignNo warnings★ 26.4K↓ —
- run-paid-campaigns-health-gategooseworks-ai/goose-skillsChecks that ads are safe to spend on: conversion tracking recording, landing pages loading on mobile with the right product, price and offer, enough stock behind promoted products, no disapproved ads, and no account or payment stop. Marks each pass, fail or unknown and turns fails into fixes. Use alone when you already have the live or planned ads and their landing pages; otherwise run run-paid-campaigns.FinanceNo warnings★ 1.3K↓ —
- run-paid-campaigns-weekly-readgooseworks-ai/goose-skillsStep of the run-paid-campaigns playbook: reads each platform's last mature results window against the allowable cost, as evidence for the week's moves. Run run-paid-campaigns instead; not for direct use.OtherNo warnings★ 1.3K↓ —
- emailhashgraph-online/awesome-codex-pluginsUse when a val sends email, receives email, or is triggered by an incoming email. Covers email-type vals (the Email handler shape, attachment limits, the assigned val email address) and sending mail via std/email.ProductivityNo warnings★ 1.5K↓ —
- baoyu-danger-x-to-markdownJimLiu/baoyu-skillsConverts X (Twitter) tweets and articles to markdown with YAML front matter. Uses reverse-engineered API requiring user consent. Use when user mentions "X to markdown", "tweet to markdown", "save tweet", or provides x.com/twitter.com URLs for conversion.MarketingNo warnings★ 27.3K↓ —
- second-brain-lintundefined-ui/second-brain-osAudit a second-brain vault for structural problems and repair them: broken wikilinks, orphan pages, empty stubs, frontmatter that violates the schema, near-duplicate pages, and stale index entries. Use this skill whenever the user asks to lint, clean, audit or check the health of their vault, says pages feel messy or links are broken, after a large bulk import, or when a scheduled maintenance run fires. Do NOT use for ingesting new sources, for answering questions from the vault, or for rewriting page content that is structurally fine but reads badly.OtherNo warnings★ 1.4K↓ —
- spec-to-repoalirezarezvani/claude-skillsUse when the user says 'build me an app', 'create a project from this spec', 'scaffold a new repo', 'generate a starter', 'turn this idea into code', 'bootstrap a project', 'I have requirements and need a codebase', or provides a natural-language project specification and expects a complete, runnable repository. Stack-agnostic: Next.js, FastAPI, Rails, Go, Rust, Flutter, and more.PlanningNo warnings★ 29.3K↓ —
- momentum-mapmohitagw15856/pm-claude-skillsBreak a stuck, stalled week with three tiny wins sequenced for momentum — because motion creates motivation, not the other way around. Use when asked I'm in a rut, help me get unstuck this week, I've stalled on everything, or I need momentum. Produces three small, genuinely-achievable wins ordered so each fuels the next, a deliberately easy first one to prove motion is possible, the dopamine logic behind the sequence, and a reframe that you don't need motivation to start — starting creates it — turning a paralyzed week into a moving one.OtherNo warnings★ 1.5K↓ —
- baoyu-danger-gemini-webJimLiu/baoyu-skillsGenerates images and text via reverse-engineered Gemini Web API. Supports text generation, image generation from prompts, reference images for vision input, and multi-turn conversations. Use when other skills need image generation backend, or when user requests "generate image with Gemini", "Gemini text generation", or needs vision-capable AI generation.MediaNo warnings★ 27.3K↓ —
- one-hard-truthmohitagw15856/pm-claude-skillsGet the single honest thing you're avoiding about a situation — said kindly but not softened away. Use when asked tell me the hard truth, what am I avoiding here, be honest with me about this, or what do I not want to hear. Produces the one thing you already half-know but keep sidestepping, said plainly and with care (not cruelty), why it's hard to face, and what facing it would actually make possible — because the truth you're avoiding is usually the one that would change things, and a kind voice can say what your own keeps ducking.OtherNo warnings★ 1.5K↓ —
- ai-eval-planmohitagw15856/pm-claude-skillsDesign an evaluation plan for an LLM or AI feature before shipping it. Use when asked how to evaluate a prompt/model/agent, set up an eval harness, define quality metrics for an AI feature, or build a regression gate.
