fable-validate-loop

# fable-validate-loop Chain fable-validate → (conditional) update issue → fableplan → work-on-issue-loop into one autonomous run: Fable 5 validates the issue, the main agent fixes the issue description if needed, Fable 5 plans the implementation (plan posted to the issue), and work-on-issue-loop implements the plan and drives the PR through review to convergence. This is fable-validate's interactive handoff made unattended — the loop reads its own verdicts and proceeds, instead of waiting for the user to reply. **Do not skip or reorder the chain.** Validation gates planning (a plan built on refuted claims is wrong), and the plan gates implementation (that's the point of routing through fableplan). The only sanctioned skip is the step-4 Capability gate (Capability < 2 / score < 50 bypasses fableplan). Every other step of each skill still runs; only the "wait for the user's reply" moments are replaced by the decision rules below. ## Input Same defaults as fable-validate: issue URL, `#<N>` / `<N>` / `owner/repo#N`, or nothing (defaults to the latest open issue in the current repo). ## Steps ### 1. Run fable-validate Invoke the `fable-validate` skill for the target issue (Skill tool, `skill: fable-validate`). Let it run fully — Fable 5 subagent validation, spot-check, verdict — producing the standard verdict block: ``` **#<N>: Update issue description? <Yes|No>** · Complexity: <score>/100 — Capability <k> (<driver>); Volume <v> · fableplan: <yes|no> · Scope: <OK | too...
