Required dispatch procedure for running a subagent on Fable 5.1: positive harness detection, the Claude Code CLI shim for other harnesses, the fallback ladder, the result-parsing contract, the attribution rule, and the caller dispatch-hygiene rules (read-only prompt, snapshot/diff, retry). Load BEFORE dispatching any `model: fable` subagent.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Fable dispatch The caller owns the prompt, subagent type, and use of the result; this skill owns the path to Fable 5.1. ## 1. Detect the harness Before dispatch, run `[ -n "$CLAUDECODE" ] && echo claude-code || echo other`. Never probe Cursor or Codex variables, and never infer the harness from an Agent-call error. ## 2. The fallback ladder 1. **Claude Code** (`$CLAUDECODE` set): the Agent tool with `model: fable`, per the caller's dispatch step and the Agent parameters below. 2. **Other harness, and `command -v claude` succeeds**: the section 3 shim, still Fable 5.1 at the intended effort. 3. **Neither path, or a shim call that failed after the section 7 retry**: the most capable model available, in order: (a) the harness's own subagent facility at its best model, keeping the caller's isolation pattern; (b) a completed shim result another model served, adopted per section 5; (c) no subagent facility: work inline in the main context and write nothing, keeping the caller's read-only promise. Report what failed and which model ran. **Agent parameters** (every Agent call a family skill makes, workers included; callers point here and never restate this): …

How to install
mdr add richkuo/rk-skills/fable-dispatch@sha256:35a84f84762ccf1bThe line at the top of this page pins the label git:20261006.4c6da76, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
