fable-validate-loop skillA
fable-validate-loop is agent-read markdown (skill) from richkuo/rk-skills: Use when the user asks to validate a GitHub issue with Fable 5.1 and then autonomously drive it to a reviewed PR in one shot — "fable-validate-loop", "fable validate and work on #N", "fully automate issue #N with fable". Runs fable-validate, auto-applies its update-issue edits when the verdict calls for it, has fableplan produce and post a Fable 5.1 implementation plan (skipped when the verdict's title-floored signal reads `fableplan: no`, which means the title score and the recomputed score are.
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
# fable-validate-loop
Chain fable-validate → (conditional) update issue → (conditional) fableplan → work-on-issue-loop into one unattended run. The loop parses each skill's output and proceeds where the interactive skill would wait for the user.
**Do not skip or reorder the chain.** Validation gates planning, and the plan gates implementation. The only sanctioned skip is the step-4 score gate (the verdict's title-floored signal reads `fableplan: no`, so the title score and the recomputed score are both below 71, with no safety flags). Every other step of each skill still runs.
## Input
Same as fable-validate: issue URL, `#<N>` / `<N>` / `owner/repo#N`, or nothing (latest open issue in the current repo).
Optional `targetBranch` (`{ issue, targetBranch }` or a prose "target branch <name>") passes unchanged to every validate, plan, and build step; `work-on-issue` step 1 ("Target") owns its validation.
## Steps
### 1. Run fable-validate
Invoke `fable-validate` (Skill tool) for the issue and let it run fully. It emits the standard verdict block:
