spec-gen: Execute Refactor

What it does

Executes a refactoring plan produced by spec-gen-plan-refactor. It treats each planned change as an independent mini-development cycle: read the plan entry, make a targeted edit (≤50 lines), diff to verify no lost code, run the specified test gate, and mark the change done only when tests pass. Includes circuit-breaker rules and safety constraints to avoid regressions.

When to use it

Use when you have a confirmed refactor plan in .spec-gen/refactor-plan.md and need an automated, disciplined executor to apply changes reliably across a codebase with strict testing and rollback rules. Not for ad-hoc edits — only for plan-driven refactors.

What's included

• Scripts: procedural guidance for read/edit/diff/test cycles; integrates with git and test commands specified in the plan (has_scripts: false in repo listing but heavy procedural content)
• References: plan format expectations and coverage thresholds
• Instructions: step-by-step mini-development loop, circuit-breaker policy, restore point procedure, and verification steps.

Compatible agents

Fits agents that can run shell/git commands and tests (CI-enabled agents, developer assistants, spec-gen MCP tooling).
