Disposable Cycle

Disposable Cycle — Orchestrator

Manage the full disposable prototyping lifecycle: spike → autopsy → distill → iterate or graduate.

Modes

Mode A: Automatic (default)

Full cycle runs automatically: spike → autopsy → distill → decision. User intervenes only at graduation decision or FAIL verdict.

Mode B: Manual

Each phase runs independently. User triggers each step:

• /disposable-spike → /disposable-autopsy → /disposable-distill

Mode is determined by $ARGUMENTS prefix (mode:auto or mode:manual) or .disposable/config.json.

Prerequisites

初回セットアップ: 各フェーズが呼び出す {plugin_root}/scripts/dist/*.mjs はビルド済みではない。存在しない場合は先にビルドする: cd {plugin_root}/scripts && npm install && npm run build

Procedure

Step 1: Initialize Session

1. Check for existing .disposable/ state:
   • If exists, load history.json and show cycle summary
   • If not, create .disposable/ with initial structure
2. Write/update .disposable/config.json:

   {
     "mode": "auto|manual",
     "maxCycles": 5,
     "qualityGates": {}
   }
   

3. Parse requirements from $ARGUMENTS (after mode prefix)

Step 2: Cycle Loop (Mode A)

while cycle_count < maxCycles:
  1. Run disposable-spike with current requirements/spec
  2. Run disposable-autopsy on completed spike
  3. Check verdict:
     - PASS → Run disposable-distill → Check graduation → maybe exit
     - CALIBRATE → Run calibration (targeted fix + re-evaluate)
     - FAIL → Run disposable-distill → Prepare next spike input
  4. If graduating → exit loop
  5. Prepare next cycle: distill-spec becomes input for next spike

Step 3: Cycle Loop (Mode B)

Report current state and available next action:

• After initialization → suggest /disposable-spike
• After spike → suggest /disposable-autopsy
• After autopsy → suggest /disposable-distill
• After distill → suggest next /disposable-spike or graduation

Step 4: History Tracking

Update .disposable/history.json after each phase:

{
  "cycles": [
    {
      "id": "cycle_1",
      "startedAt": "ISO8601",
      "phases": {
        "spike": { "completedAt": "ISO8601", "metricsRef": "spike-complete.json" },
        "autopsy": { "completedAt": "ISO8601", "verdict": "CALIBRATE" },
        "distill": { "completedAt": "ISO8601" }
      },
      "verdict": "CALIBRATE",
      "graduated": false
    }
  ],
  "currentCycle": "cycle_2",
  "totalCycles": 2
}

Step 5: Graduation Decision

When autopsy verdict is PASS, evaluate graduation criteria:

1. No unaddressed must constraints across all cycles
2. Architecture decisions stable (no reversals in last 2 cycles)
3. All interface contracts validated
4. Open questions resolved

If criteria met:

• Present graduation summary to user
• Ask: graduate to production or iterate once more?
• If graduating:
  1. Compile final distill spec with all cycle learnings
  2. Switch to base branch: git checkout main (or the branch active before the cycle)
  3. Clean up spike branches: git branch --list 'disposable/cycle_*' | sed 's/^[* ]*//' | xargs -r git branch -D
  4. Archive .disposable/ state
  5. Output production-ready specification

Step 6: Cleanup

On completion or user abort:

• Release .disposable/.lock
• Update history.json
• Report session summary:
  • Total cycles run
  • Verdict progression
  • Key learnings extracted
  • Final recommendation

Configuration

.disposable/config.json options:

Safety

• All code generation happens on isolated disposable/cycle_{N} branches
• No network access during spike generation (see security-policy.md)
• Sensitive data masked in all artifacts (see mask-sensitive.mjs)
• Lock file prevents concurrent cycles
• Maximum cycle limit prevents infinite loops
