The open format is called Agent Skills and works in Claude Code, Codex, Cursor and other agents — most people know it as Claude Skills.
Every Agent Skill we could find on GitHub, deduplicated by content. 79 870 files from 1 769 authors, of which 62 217 are unique — the rest is the same skill repackaged into someone else's repository. For each one: what it weighs in tokens, whether it ships runnable scripts, and which MCP servers it needs.
Generate story concepts using a genre-first approach. Use when starting a new project, when brainstorming ideas, when a concept needs strengthening, or when you want to ensure emotional impact drives the story.
Systematically evaluate completed short stories or novel chapters to identify strengths, weaknesses, and improvement opportunities. Use after drafting to assess whether the piece achieves its narrative goals.
Act as an active writing partner who contributes content alongside the human writer. Use when the writer wants a collaborator who generates prose, dialogue, alternatives, and builds on their ideas. Applies Story Sense frameworks while actively contributing to the creative work. Contrasts with story-coach which never writes.
Generate stories about institutional outcasts given impossible mandates with minimal resources. Use when you want team dynamics in hostile institutions, David vs. Goliath within organizations, or narrative tension from constraint-driven creativity.
Act as an assistive writing coach who guides but never writes for the user. Use when helping someone develop their own writing through questions, diagnosis, and frameworks. Critical constraint - never generate story prose, dialogue, or narrative content. Instead ask questions, identify issues, suggest approaches, and let the writer write.
Diagnose what any story needs regardless of its current state. This skill should be used when a writer is stuck, evaluating story problems, when narrative feels broken, or when someone asks 'what's wrong with my story?'. Keywords: story, diagnosis, stuck, narrative, plot, character, worldbuilding, revision.
Transform predictable story elements into fresh, original versions. Use when something feels generic, when feedback says "I've seen this before," when elements orbit the protagonist too conveniently, or when you want to make a familiar trope feel new. Applies the 8-step CTF process and Orthogonality Principle.
Break through blocks and execute first drafts. Use when the outline is done but the draft isn't happening, when writer's block strikes, when the blank page remains blank, or when progress stalls.
Diagnose genre problems and generate genre-specific elements. Use when genre promise is unclear, when elements feel misplaced, when secondary genres compete with primary, or when you need genre-specific entropy. Covers all 11 elemental genres from the Writing Excuses framework.
Guide the edit pass after drafting. Use when revision feels overwhelming, when changes cascade unpredictably, when you can't see problems anymore, or when editing never ends.
Autonomously draft and polish chapters through multi-skill editorial passes. Use when you have a complete outline and want to produce a polished first draft with iterative refinement.
Diagnose sentence-level issues after structure is solid. Use when prose feels flat, sentences are monotonous, word choices are generic, or voice is inconsistent.
Diagnose weak endings, rushed resolutions, and arbitrary conclusions. Use when stories build well but end disappointingly, when climax feels unearned, or when resolution doesn't complete character arcs.
Structure stories around essential emotional moments using Rodriguez's approach integrated with elemental genres. Use when plotting feels mechanical, when emotional beats need defining, or when building stories from vivid scenes rather than plot outlines.
Manage multi-level novel revisions while preventing cascade problems. Use when editing novels, when changes at one level break things at others, when you need systematic change management for long-form fiction, or when revisions keep creating new problems.
Structure stories around protagonists who refuse to acknowledge what they're becoming. Use when exploring self-deception, moral transformation, or the gap between self-perception and reality.
Generate speculative fiction stories about systemic exploitation by collapsing comfortable moral distances. Use when exploring how privilege and harm are connected, when writing about systems that export consequences, or when you want stories where innocence becomes impossible.
Act as an active outline partner who develops structure collaboratively. Use when developing, iterating, or improving story outlines. Generates scene beats, character arcs, plot structures, and exploratory prose samples. Contrasts with story-collaborator which drafts finished prose.
Act as an assistive outline coach who guides structural development through questions. Use when helping someone develop their own outline through diagnosis and frameworks. Critical constraint - never generate outline content. Instead ask questions, identify structural issues, suggest approaches, and let the writer structure.
Structure multi-POV stories through catalyst environments. Use when building interconnected narratives, when perspectives need meaningful intersection, or when a shared setting needs to generate distinct storylines.
Generate stories where ordinary people become crucial through their structural position in systems. Use when you want protagonists who aren't chosen ones but accidental pivots, when mundane jobs should reveal conspiracies, or when you need structurally inevitable involvement rather than coincidence.
Reverse-engineer published books into structured scene-by-scene outlines for study. Use when analyzing craft, learning story structure from masters, or creating teaching materials from existing works.
Structure scenes and control pacing using scene-sequel rhythm. Use when individual scenes work but don't accumulate, when pacing feels off (too rushed or too slow), when transitions feel mechanical, or when readers can follow but aren't compelled forward. Based on Dwight Swain's Goal-Conflict-Disaster and Reaction-Dilemma-Decision structure.
Manage multi-level story synchronization. Use when changes at one abstraction level (pitch, structure, scenes, entities, prose) need to propagate to others, or when story elements feel inconsistent across levels.
Design religious and belief systems for fictional worlds. Use when creating pantheons, religious institutions, spiritual practices, or any belief structures that shape society and drive character motivation.
Generate phonologically consistent constructed languages for fiction. Use when you need naming languages, alien speech, or fantasy tongues without deep linguistics knowledge.
Design political entities and governance systems for fictional worlds. Use when creating kingdoms, empires, federations, or any political structures that need realistic internal complexity and external relationships.
Design economic systems for fictional worlds. Use when worldbuilding needs currencies, trade networks, resource economies, or when economic pressures should drive plot and character motivation.
Design cultures for closed-loop life support systems in space. Use when worldbuilding stations, ships, or habitats where recycled matter creates novel social structures, beliefs, and conflicts.
Design evolving language systems for fictional worlds. Use when creating language families, dialects, linguistic history, or when language should reflect cultural and historical development.
Create worldbuilding quotes and epigraphs through documentary perspectives. Use for chapter epigraphs, in-world documents, or any content where limited perspective creates meaning through what the documenter cannot see.
Design cities, towns, and settlements for fictional worlds. Use when creating urban environments, mapping city districts, or when settlements need realistic layered development and spatial logic.
Build worlds through cascading consequences from speculative changes. Use when introducing new technologies, species, or alternate histories and need to trace realistic societal transformations across multiple domains.
Manage long-term fate and fortune across a shared world. Use when powerful entities feel permanent, when the world becomes static, when you need probabilistic death/fall mechanics, or when campaigns need world-level consequences that persist. Operates above the game-facilitator level.
Diagnose world-level story problems. This skill should be used when settings feel thin, institutions feel designed rather than evolved, economies don't make sense, or non-human species feel like humans in costume. Keywords: worldbuilding, setting, world, institutions, economy, culture, species, consequences.
Diagnose and improve humor using systems thinking. Use when jokes fall flat, when humor feels forced, when punchlines don't land, or when you want to systematically enhance comedic writing. Treats jokes as engineerable connection systems.
Diagnose lyric problems across prosody, rhyme, meaning, register, sound, and structure. Use when AI-generated or human lyrics feel flat, cliched, awkward, or mismatched.
Extract descriptive musical characteristics from any artist or band without using their name, building a vocabulary of sonic qualities for AI music generation, music description, or creative recombination.
