# Prepare `SPAE` ## When to use - The user wants to run the preparatory phases of the `SPAE` structured workflow autonomously: spec, plan, and inspect. ## Goal - Spawn `spec`, `plan`, and `inspect` subagents sequentially based on `STATE.json` status and phase. - Halt successfully when the `workstream` reaches `phase: build`, or halt immediately on errors. ## Input Read `.spae/current/STATE.json` to resolve the current execution phase and cursor. Accept an optional argument, the proposal, during initial execution. ## `STATE.json` See `references/STATE.md` for the field reference, directives, and phase snapshots. ## Phase-agent map Every phase maps to exactly one subagent, spawned the same way regardless of phase: | `phase` | Subagent | | --------- | --------- | | `spec` | `spec` | | `plan` | `plan` | | `inspect` | `inspect` | ## Workflow 1. **Resolve Workstream**: - Locate `.spae/current/STATE.json`. - Missing, no proposal argument: halt. - Missing, proposal provided: spawn `spec` with the proposal; await completion; proceed to step 2. - Present: proceed to step 2 without spawning. 2. **Dispatch Loop**: - Re-read `.spae/current/STATE.json`; record `phase`. - Exit on `phase: "build"`. - Halt immediately if `phase` matches none of the phase-agent map's rows. - Spawn the subagent the map names for the recorded `phase`, no arguments. - Await completion; halt immediately on `Failed` status or any proce
