Fable 5 Skills

AI reasoning skills, mathematically distilled from 4,665 real Claude Fable 5 chain-of-thought traces.

Tuned to Grade A · 100.00% emulation accuracy against MiniMax M3 across 9 iterative test rounds.

Why

Modern coding agents are powerful, but they often skip verification, guess instead of investigate, and leave loose ends. Fable 5 doesn't. Across 4,665 real turns captured in the source dataset, Fable 5:

• Verifies after 87.7% of actions
• Reads the file before editing in 93.5% of edits
• Self-corrects in 56.4% of reasoning turns — then continues forward 74.4% of the time
• Uses a tight per-turn loop: ACKNOWLEDGE → OBSERVE → EXECUTE → VERIFY
• Speaks in professional, action-heavy prose (4.39 tool-to-text ratio)

fable5-skills packages these measurable behaviors into 5 drop-in SKILL.md files so any agent that reads markdown — Claude Code, Cursor, Cline, Windsurf, Continue, MiniMax M3, any custom agent — can adopt Fable 5's discipline in one command.

npx fable5-skills init

📦 Installation

You don't need to install anything globally. Just run npx:

# Default — installs into .claude/skills/ (Claude Code layout)
npx fable5-skills init

Other agent layouts

npx fable5-skills init --agent=cursor       # .cursor/skills/
npx fable5-skills init --agent=cline        # .cline/skills/
npx fable5-skills init --agent=windsurf     # .windsurf/skills/
npx fable5-skills init --agent=continue     # .continue/skills/
npx fable5-skills init --agent=generic      # ./skills/
npx fable5-skills init ./my-project         # install into a specific project

Install via skills.sh (open agent skills marketplace)

This package is also indexed on skills.sh — the open agent skills directory. If you use the skills CLI, you can install any of the 5 Fable 5 skills into 70+ supported coding agents:

# List available skills
npx skills add ahmdd4vd/Fable5res --list

# Install a specific skill (e.g. fable-debug) into Claude Code + Cursor
npx skills add ahmdd4vd/Fable5res --skill fable-debug -a claude-code -a cursor

# Install all 5 skills into all detected agents
npx skills add ahmdd4vd/Fable5res --all

The skills CLI auto-detects which coding agents you have installed (Claude Code, Cursor, Cline, Codex, Windsurf, Continue, Gemini CLI, GitHub Copilot, OpenCode, and 60+ more) and installs the SKILL.md files into the correct paths for each.

Useful flags

npx fable5-skills init --only=fable-debug   # install a single skill
npx fable5-skills init --force              # overwrite existing
npx fable5-skills init --dry-run            # preview without writing
npx fable5-skills doctor                    # verify package integrity

🧠 The 5 Skills

Each SKILL.md is self-contained, composable, and verifiable against the source dataset.
