Use when the user wants a task planned by a Fable 5.1 planning subagent. Spins up a Plan subagent running on Fable 5.1 to produce an implementation plan, checks it against the code, relays it to the main agent, and — if a GitHub issue is referenced — posts the plan as a comment on that issue, then stops. It never builds. Trigger on "/fableplan", "fableplan this", or "plan this with fable".
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
# fableplan
Delegate planning to a **Fable 5.1** Plan subagent. The main agent checks the plan, posts it, presents it, and stops. Neither one builds: no worktree, no code edits, no pull request.
## Input
The user provides a task description, and optionally a GitHub issue:
- A task in prose ("fableplan adding X to Y").
- A GitHub issue reference — full URL, `#<N>`, bare `<N>`, or `owner/repo#N`. When present, the plan is also posted as an issue comment.
- If neither is obvious, ask the user what to plan before dispatching.
## Steps
### 1. Resolve the GitHub issue (only if one is referenced)
If the user named an issue, fetch it so the subagent plans against the real requirements, not a paraphrase:
```
gh issue view <N> --json number,title,body,url
```
For the `owner/repo#N` form (or a full URL to another repo), add `-R owner/repo` — a bare `gh issue view <N>` only resolves against the current repo.
If the command fails (wrong number, no auth, no repo), stop and tell the user — never proceed by planning against your paraphrase of an issue you couldn't fetch.

How to install
mdr add richkuo/fableplan/fableplan@sha256:f49ec640a70236b7The line at the top of this page pins the label git:20261002.abce3ac, 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.
