Is the GAT Story skill free?

Yes. The skill itself is free from Yuki001/game-dev-skills. SkillProof publishes the install command and an independent test verdict at no cost.

What is the GAT Story SkillProof Score?

6.8/10 — installs cleanly 3/5, triggers reliably 5/5, output vs. baseline 6/10, docs & honesty 3/5.

How do I install GAT Story?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use GAT Story with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 6.8/10
Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · ce9f9c1

Simulated the interview live: skill correctly asked one narrative-need question with a recommended answer and waited, a real behavioral difference from a baseline that just dumped a full story pitch. But Phase 3 ("spawn gat-writer to write the docs") and the cited templates both live outside the skill's own folder (gat/.claude/agents/, gat/.claude/docs/templates/design/) -- a plain cp -r of gat-story alone leaves the skill unable to actually produce gat/narrative/*.md.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What GAT Story does

Runs a structured, single-question-at-a-time writer interview covering premise, world, characters, quests, dialogue and tone, then spawns a gat-writer subagent to produce docs under gat/narrative/. Triggers when a user wants story, lore, worldbuilding or dialogue for a GAT-toolkit game; it is one module of a larger multi-skill/multi-agent toolkit, not a standalone file.

How to install GAT Story

git clone https://github.com/Yuki001/game-dev-skills
cd game-dev-skills
mkdir -p ~/.claude/skills
cp -r gat/.claude/skills/gat-story ~/.claude/skills/gat-story

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
