batch-simplifylisted

## Repository context. Gather first Collect these with **individual** Bash calls, one command per call, never combined into a single invocation: - Current branch, `git branch --show-current` Treat a failure (not a repository, git unavailable) as an unknown value and carry on. Keep these as separate body Bash calls rather than pre-compute lines: the harness runs a skill's whole pre-compute block as one shell invocation, and a worktree-isolated session refuses a compound command that contains git. ## Purpose Automate running simplification across changed code files, or every code file in the repository, grouped so each pass has tight focus and ecosystem-appropriate context. Replaces the manual process of remembering to run `/simplify` after each task. ## Emit checklist For any batch run (Phases 1-8), copy `templates/checklist.md` into your project's working-notes location (or track the phases inline if it has none). Tick each phase as completed. Phase 6.5 SKIPPED when no deferred items surface; Phase 5 task tracking SKIPPED for single-group changes. ## Arguments `$ARGUMENTS`, optional scope for the file scan: `[<scope>] [<path>...] [docs]`. The scope picks a *universe* (three modes below); a path narrows it to a *region*. They are independent, so any scope takes any path. ### Mode 1: Time window (default) Supported formats: `24h`, `48h`, `72h`, `7d`, `2d`, `1w`. Default: `48h`. **Normalize before use:** git's `--since` approxidate parser requires `24 hours`, not `24
