re0-plan

• SKILL.mdcore · 5,316 bytes

Open `.re0/iteration/<version>-<workname>/` and write into it in the same motion, before a single line of `re0-loop`'s cycle runs.

## Goal

A cycle without a written thesis, gate list, and step plan drifts to whatever framing comes first — and a folder opened with nothing in it tells a resumed session nothing at all. `re0-plan` closes both gaps at once: the folder is never empty from the moment it's created, regardless of which weight the cycle turns out to be. It assumes the full paperthin package installed and names its sibling skills directly. It pairs with `re0-release`, which retires the folder, and `re0-memo`, which extends whatever this skill seeded instead of restarting fresh. It is not a portable planning method — the shape it writes is this repo's own convention.

## Workflow

1. Classify the cycle's weight: a fix or hardening pass with no real design surface is **lightweight**; a cycle with a direction genuinely worth arguing through is **full**.
2. Create `.re0/iteration/<version>-<workname>/` and, in the same step, write its first file — the weight decides which:
   - **lightweight** → `RETRO.local.md`: one paragraph naming the task and why it's lightweight. `re0-memo` extends this same file at the end; it never starts a fresh one. Stop here.
   - **full** → `DESIGN.local.md`: thesis, scope, and quality gates — the same content `re0-loop`'s FRAME turn expects, and enough on its own to survive a session break. When the change touches shippable surface, those gates always include an AGENTS.md/README reflection gate (see Rules). Confirm the read with `readchk`, size the tier with `modelchk`; reach for `macrothink` or another judgment skill only when the direction is genuinely contestable.
3. (full only) Write `WORKFLOW.local.md`: the numbered steps this specific cycle runs through `re0-loop`'s turn order — specific to this build, not a restatement of `re0-loop`'s generic stages.
4. (full only) Write `EVIDENCE.local.md`: the gates from `DESIGN.local.md`, listed as proof surface still to fill — the bar, not results.
