  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 1 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by Yuki001 on GitHub. Read the source before you install it.

Installation

Install the Gat Story AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/Yuki001/game-dev-skills/tree/main/gat/.agents/skills/gat-story
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/Yuki001/game-dev-skills.git /tmp/game-dev-skills
mkdir -p .claude/skills
cp -r /tmp/game-dev-skills/gat/.agents/skills/gat-story .claude/skills/gat-story
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Gat Story in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Gat Story on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Gat Story is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Story

Codex Runtime

This skill is fully contained in the installed .agents directory. Resolve all linked resources relative to this SKILL.md; do not read workflow resources outside this packaged directory.

Before acting, read GAT Workflow. Read Directory Structure or Workflow Catalog only when their structure or ownership details are needed.

Use these packaged role profiles for every role-specific pass:

When the workflow says to spawn one of these roles, create a Codex subagent with that exact task name when collaboration is available. Give it the complete role profile, relevant source documents, confirmed decisions, template, and exact target paths; wait for it and review its result before continuing. This skill explicitly authorizes those named workflow subagents. If subagents are unavailable, perform the same pass yourself using the packaged role profile.

Treat the directory containing .agents as the repository root. All GAT project documents live under that root's gat/ directory. Use Codex filesystem tools and the environment's supported patch editor while preserving unrelated user changes.

Interpret AskUserQuestion in the procedure as a single concise user question. Use a structured choice UI only for a genuine 2-3 option decision; otherwise ask in ordinary dialogue and wait. Command examples use Codex skill syntax ($gat-*).

This skill explores and documents a game's narrative through open-ended writer interview. Spawn gat-writer for narrative reasoning. Spawn gat-designer or gat-artist only when story choices need design-system or visual-direction checks. Pick questions from the angle table below — follow the conversation, not a script.

Phase 1: Resolve Mode

  • If argument is discuss → Mode: discuss (no files written, exploration only)
  • If argument is a hint or empty → Mode: story (produces narrative docs under gat/narrative/)

Check whether these files exist:

  • gat/overview/game.md
  • gat/overview/systems-index.md
  • gat/overview/art-direction.md
  • gat/narrative/story.md
  • gat/narrative/world.md
  • gat/narrative/characters.md
  • gat/narrative/quests.md
  • gat/narrative/dialogue.md

If foundational overview docs exist, read them before asking questions that they already answer. If they are missing, proceed only with high-level narrative brainstorming and note that final narrative docs may need revision after $gat-brainstorm establishes the game overview and systems.

Phase 2: The Interview

Core Rules

  • One question at a time. Never batch. Wait for the answer before the next question.
  • Provide a recommended answer with each question. Explain the narrative reasoning.
  • Prefer open-ended questions. Let the user type free-form responses. Reserve AskUserQuestion for concrete options where the user needs to choose.
  • Pick angles, don't follow steps. Use the angle table as a menu. Jump to whatever dimension is most useful next.
  • If a question can be answered by reading existing files, read them instead of asking.
  • Spawn gat-writer when you need narrative synthesis: premise, tone, character arcs, world logic, quest structure, dialogue voice, or consistency checks.
  • Spawn gat-designer when narrative choices affect mechanics, system ownership, progression, player agency, or content volume.
  • Spawn gat-artist when narrative choices affect visual identity, character/world art hooks, readability, motifs, or asset groups.

Drilling into Vague Narrative Ideas

When the user has a fuzzy story idea, make it playable and specific through curious questioning.

How to drill:

  • When the user says the story should feel a certain way, ask what event, character choice, or player action creates that feeling.
  • When the user mentions lore, ask how the player encounters it: dialogue, quest, item text, environment, UI, systemic event, or cutscene.
  • When a character is named, ask what they want, what blocks them, how they pressure the player, and whether they change.
  • When the user references another work, isolate what to borrow: structure, tone, world texture, relationship dynamic, mystery shape, or dialogue style.
  • When a branching idea appears, ask how many branches must be produced and whether consequences are cosmetic, systemic, or story-changing.
  • When a world fact appears, ask what it causes in daily life, factions, resources, locations, or mechanics.
  • If an answer opens three new questions, resolve the one that most affects player role, stakes, or content scope first.

Signals that something is still vague and needs more drilling:

  • The user uses abstract story adjectives without concrete beats behind them ("dark", "emotional", "epic", "mysterious", "cozy")
  • The protagonist, antagonist, or player role lacks motivation
  • The world has lore but no player-facing delivery method
  • The story can be summarized but not played
  • Branching is proposed without content-budget boundaries
  • Tone conflicts with gameplay, art direction, or target audience

Seed Extraction

If a concept hint was provided, first spawn gat-writer to extract what the hint already answers. Briefly summarize what's established so the user can confirm or correct before diving in. Skip if no hint.

Interview Angles

Pick questions from any angle below. There is no fixed order — follow the thread that matters most at each moment. The table is a palette, not a checklist.

#AnglePurposeExample prompts
1Narrative NeedDecide whether the game needs light flavor, authored story, or deep narrative systemsHow much story does this game need to work? Could it be mostly atmospheric, or does it need plot progression?
2Player RoleAnchor story to the player's fantasy and verbsWho is the player in the world? What do they do that matters narratively?
3Premise & ConflictDefine the situation and pressureWhat is wrong with the world when play begins? Who or what opposes the player?
4StakesMake outcomes meaningfulWhat happens if the player fails? Are the stakes personal, communal, cosmic, comedic, or material?
5ThemeClarify what the story is about beneath plotWhat question does the story keep asking? What value is being tested?
6ToneSet the audience contractShould this feel sincere, tragic, funny, eerie, heroic, cozy, satirical, or something else?
7StructureShape story progressionIs the story linear, episodic, hub-based, branching, cyclical, or emergent?
8World RulesBuild coherent setting constraintsWhat facts about the world must always be true? What can never happen here?
9Factions & PowerCreate social pressure and conflictWho holds power? Who wants change? What resources are scarce?
10LocationsTurn setting into playable placesWhich places must the player visit, revisit, or transform? What does each location do for the story?
11CharactersDefine cast function and arcsWho matters to the player? What does each major character want, and how do they change?
12AntagonismClarify oppositionIs the antagonist a person, system, environment, mystery, inner flaw, or rival goal?
13RelationshipsCreate emotional stakesWhich relationships carry the story? Ally, rival, mentor, dependent, enemy, community?
14Quests & BeatsMap narrative into player actionWhat are the key story beats, and what does the player do during each one?
15Choice & ConsequenceBound interactivityWhich choices matter? Are consequences immediate, delayed, cosmetic, mechanical, or ending-related?
16Dialogue & VoiceDefine how characters soundHow talkative is the game? Do characters speak in full conversations, short barks, UI text, or silent implication?
17Environmental StorytellingExpress story without expositionWhat should the player infer from spaces, props, signs, ruins, UI, enemies, or routines?
18Lore BudgetPrevent scope creepHow many factions, named NPCs, locations, lore entries, quests, and endings are reasonable for MVP?
19Art HooksConnect narrative to visualsWhat motifs, silhouettes, symbols, color meanings, or materials should art direction carry?
20Sensitivity & RatingAvoid harmful or mismatched contentAre there themes that need content warnings, cultural review, age-rating limits, or softer handling?
21Localization & ReadabilityKeep text producible and readableHow text-heavy can the game be? Does dialogue need to be easy to localize, skip, replay, or summarize?

Navigating the Interview

  • Start where the energy is. If the user leads with a character, start there. If they lead with setting, start with world rules. If they lead with mechanics, start with player role and story delivery.
  • Drill, don't move on. When the answer is abstract, ask the follow-up that turns it into a beat, role, rule, or delivery method.
  • Ask open-ended, resolve with options. Most questions should be dialogue. Use AskUserQuestion only when choosing among concrete narrative proposals.
  • Spawn gat-writer mid-interview when you need a concise story proposal, character arc set, quest structure, or consistency pass. Present the result, then ask what to keep or change.
  • Loop back naturally. If a later answer contradicts an earlier canon point, point it out and resolve the tension.
  • Know when to stop. The interview has covered enough when:
    • The player role, premise, conflict, stakes, tone, and theme are clear
    • The story delivery method is known
    • The world has enough rules and locations for the game's scope
    • Major characters or factions have motivations and functions
    • Narrative content volume is bounded
    • The user starts repeating themselves rather than adding new information

Phase 3: Write or Summarize

If Mode is story

Before writing, summarize what's been decided across premise, world, characters, structure, delivery, scope, and open questions. Ask:

"Ready to write the narrative docs?" Options: Yes, write them / Let me keep discussing

If yes, read the relevant templates:

  • ../../assets/templates/design/narrative-story.md
  • ../../assets/templates/design/narrative-world.md
  • ../../assets/templates/design/narrative-characters.md
  • ../../assets/templates/design/narrative-quests.md
  • ../../assets/templates/design/narrative-dialogue.md

Spawn gat-writer to write the narrative docs under gat/narrative/.

Always write or update:

  • gat/narrative/story.md

Write or update these only when the game needs them:

  • gat/narrative/world.md for setting rules, factions, locations, culture, or environmental storytelling
  • gat/narrative/characters.md for named cast, factions-as-characters, voice, arcs, or relationships
  • gat/narrative/quests.md for authored missions, story objectives, progression beats, or branching consequences
  • gat/narrative/dialogue.md for conversations, barks, VO, UI narrative text, or reusable voice rules

Pass all interview answers, existing overview/narrative files, and the selected templates. Instruct the writer to preserve template metadata and source-reference sections, mark uncertain material as open questions, and keep outputs concise.

If Mode is discuss

Summarize what was decided and what remains open. No files written.

Suggest:

  • $gat-story (without discuss) to turn this discussion into narrative docs
  • $gat-milestone to plan milestone slices after overview (and narrative, if needed) are ready

Phase 4: Hand Off

Summarize what was created or discussed.

If narrative docs were written, suggest next steps:

  • $gat-milestone to plan milestone slices (milestone planning runs BEFORE per-system design; do NOT run $gat-design directly from here)
  • If story revealed or changed systems, update gat/overview/systems-index.md (via $gat-brainstorm or directly) before planning milestones

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Gat Story AI skill do?

Develop or refine a GAT game's premise, world, characters, quests, dialogue, tone, and narrative delivery through a one-question-at-a-time interview, then write the needed global narrative documents; also supports discussion-only exploration.

Why use Gat Story on TypingMind?

Because you install it once and use it with any model. Gat Story is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Gat Story in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Yuki001/game-dev-skills/tree/main/gat/.agents/skills/gat-story. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Gat Story?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Gat Story?

As many as you like. As long as a model supports skills, you can use Gat Story with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Gat Story AI skill free?

It is published on GitHub by Yuki001. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
