fableplan skillA

fableplan is agent-read markdown (skill) from richkuo/rk-skills: Use when the user wants a task planned by a Fable 5.1 planning subagent before building it. Spins up a Plan subagent running on Fable 5.1 to produce an implementation plan, relays the plan back to the main agent, and — if a GitHub issue is referenced — posts the plan as a comment on that issue and asks the user whether to continue building now before proceeding. Trigger on "/fableplan", "fableplan this", or "plan this with fable"..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# fableplan

A **Fable 5.1** Plan subagent writes the plan. The main agent checks it, posts it, and builds from it. The subagent never builds.

## Input

A task description, with an optional issue reference (URL, `#<N>`, bare `<N>`, or `owner/repo#N`). With an issue, the plan is also posted as a comment. Ask what to plan only when the task is unclear. With no issue, never invent one or post anywhere.

## Steps

### 1. Resolve the GitHub issue (only if one is referenced)

`gh issue view <N> --json number,title,body,url` (add `-R owner/repo` for another repository). Stop and tell the user if it fails; never plan from a paraphrase of an issue you could not fetch. Record the number and URL for step 4. Read any **Plan effort** line in the body's `## Execution` block: planning runs at that tier when present, else `high`; a stamped `xhigh` runs at `xhigh`.

### 2. Dispatch the Fable 5.1 Plan subagent
