Task: assemble a fable-method domain adapter for the new 'localization / translation QA' sector — first without skill, then strictly according to the skill's body. Baseline run (I copied the schema from an existing marketing.md) yielded 39 lines, 6/8 mandatory TEMPLATE.md sections, zero sources, and no flowcharts. Skill run yielded 74 lines, 8/8 sections, a mermaid flowchart, and 3 sources with access dates, of which I actually verified CLDR plural rules via fetch and confirmed six categories and minimal pairs; ISO 17100 confirmed the requirement for bilingual revision by a second linguist. The repository's own CI (python .github/checks.py) passed green on both adapters — it only greps two headers, so the real difference was provided by the skill itself, not CI. Honesty spot-check: README statements (Haiku 2→6, Sonnet 9→10, Opus 8→9) matched committed eval/results/round12-13 to the point, including zeros unfavorable to the author. Minus: the repository's install.sh does not install fable-domain at all (0 mentions), and the skill's body refers to references/domains/TEMPLATE.md, which is located in the fable-method skill — hence two `cp` lines in install; I did not run the trap-fixture and smoke-eval from Stage 3-4, and this was not checked.

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

  • Installs cleanly 4/5
  • Triggers reliably 4/5
  • Output vs. baseline 8/10
  • Docs & honesty 5/5

What Fable Domain does

Turns a sector into a Fable-method domain adapter: a step-by-step workflow with a mermaid flowchart, a fraud table, a trap fixture, and a Sources section where every named regulation carries a fetched link and access date. Triggers on "/fable-domain <sector>", "make a skill for <domain>", or adding a domain to the fable method. Refuses outright on licensure and high-harm domains and stops early when a sector does not differ from the coding default.

How to install Fable Domain

git clone https://github.com/Sahir619/fable-method
mkdir -p ~/.claude/skills
cp -r fable-method/skills/fable-method ~/.claude/skills/fable-method
cp -r fable-method/skills/fable-domain ~/.claude/skills/fable-domain

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

Commands — how to trigger Fable Domain

  • /fable-domain Generates a sourced domain workflow: adapter, flowchart, trap fixture, eval

It also activates on plain-language prompts like these:

  • Make me a workflow adapter for localization QA with sourced regulations
  • Add a new domain to the fable method for translation quality checks
  • Build a fraud table and trap fixture for this new industry workflow

Frequently asked questions

Is the Fable Domain skill free?
Yes. The skill itself is free from Sahir619/fable-method. SkillProof publishes the install command and an independent test verdict at no cost.

How do I install Fable Domain?
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 Fable Domain 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.
