re0-plan

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.
5. Keep reference material flat as REF-<topic>.local.md; promote to a refs/ subfolder only once it multiplies past a couple of files.
6. Hand off to re0-loop. Do not invoke re0-work here — a from-scratch restart is re0-loop's own mid-cycle call, surfaced by nba when warranted, never a setup step.
