Use for heavy implementation, debugging, test fixing, or multi-file edits Codex could execute, or orchestrating Claude + Codex.
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-GPT: Claude orchestrates, Codex executes ## Role split - **Claude (main thread):** planning, repo understanding, architecture decisions, task decomposition, final review, small surgical edits. - **Codex (codex plugin):** heavy implementation, debugging, test fixing, refactors, multi-file edits. Runs on the ChatGPT subscription — zero Claude tokens for execution. Global default is `gpt-5.5` at `xhigh` reasoning (`~/.codex/config.toml`); do not pass `--model`/`--effort` unless deliberately overriding. ## How to delegate | Situation | Route | |---|---| | Quick, bounded task | `/codex:rescue` (foreground) | | Big, open-ended, or long-running | `codex-rescue` subagent (already `model: sonnet`, Bash-only — passes agent-model-guard) or `--background`; poll `/codex:status`, fetch `/codex:result` | | Continue prior Codex work | say "resume"/"continue" (maps to `--resume-last`) | | Routine pre-commit review or second-opinion diagnosis | `/codex:review` — default here before spending Claude subagent tokens; reserve `/code-review` or `/adversarial-review` for high-stakes diffs | ## Task prompt shape (keep it focused) ``` Goal: [one sentence] Files: [paths] …

How to install
mdr add ucsandman/claude-skills/fable-gpt@sha256:44bd4c792ae0841bThe line at the top of this page pins the label git:20260904.14d2e37, 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.
