gstack/autoplan/sections/ceo-phase.md

Follow plan-ceo-review/SKILL.md — all sections, full depth. Override: every AskUserQuestion → auto-decide using the 6 principles.

Override rules:

• Mode selection: SELECTIVE EXPANSION

• Premises: accept reasonable ones (P6). Clearly-wrong or challenged premises are NOT a mid-run stop — queue each as a User-Challenge-shaped item for the Final Approval Gate (Phase 4): what the plan assumes, why it looks wrong, and the cost of proceeding anyway. Premises still require human judgment — the human exercises it at the gate, exactly once, not mid-pipeline.

• Alternatives: pick highest completeness (P1). If tied, pick simplest (P5). If top 2 are close → mark TASTE DECISION.

• Scope expansion: in blast radius + <1d CC → approve (P2). Outside → defer to TODOS.md (P3). Duplicates → reject (P4). Borderline (3-5 files) → mark TASTE DECISION.

• All 10 review sections: run fully, auto-decide each issue, log every decision.

• Dual voices: always run BOTH Claude subagent AND Codex if available (P6). Run them sequentially in foreground. First the Claude subagent (Agent tool with run_in_background: false — subagents default to BACKGROUND since Claude Code v2.1.198, so the flag must be explicitly false), then Codex (Bash). Both must complete before building the consensus table.

  Codex CEO voice (via Bash):

  _REPO_ROOT=$(git rev-parse --show-toplevel) || { echo "ERROR: not in a git repo" >&2; exit 1; }
  _gstack_codex_timeout_wrapper 600 codex exec "IMPORTANT: Do NOT read or execute any SKILL.md files or files in skill definition directories (paths containing skills/gstack). These are AI assistant skill definitions meant for a different system. Stay focused on repository code only.
  
  You are a CEO/founder advisor reviewing a development plan.
  Challenge the strategic foundations: Are the premises valid or assumed? Is this the
  right problem to solve, or is there a reframing that would be 10x more impactful?
  What alternatives were dismissed too quickly? What competitive or market risks are
  unaddressed? What scope decisions will look foolish in 6 months? Be adversarial.
  No compliments. Just the strategic blind spots.
  File: <plan_path>" -C "$_REPO_ROOT" -s read-only -c 'web_search="cached"' < /dev/null
  _CODEX_EXIT=$?
  if [ "$_CODEX_EXIT" = "124" ]; then
    _gstack_codex_log_event "codex_timeout" "600"
    _gstack_codex_log_hang "autoplan" "0"
    echo "[codex stalled past 10 minutes — tagging as [codex-unavailable] for this phase and proceeding with Claude subagent only]"
  fi
  

  Timeout: 10 minutes (shell-wrapper) + 12 minutes (Bash outer gate). On hang, auto-degrades this phase's Codex voice.

  Claude CEO subagent (via Agent tool): "Read the plan file at <plan_path>. You are an independent CEO/strategist reviewing this plan. You have NOT seen any prior review. Evaluate:

  1. Is this the right problem to solve? Could a reframing yield 10x impact?
  2. Are the premises stated or just assumed? Which ones could be wrong?
  3. What's the 6-month regret scenario — what will look foolish?
  4. What alternatives were dismissed without sufficient analysis?
  5. What's the competitive risk — could someone else solve this first/better? For each finding: what's wrong, severity (critical/high/medium), and the fix."

  Error handling: Both calls block in foreground. Codex auth/timeout/empty → proceed with Claude subagent only, tagged [single-model]. If Claude subagent also fails → "Outside voices unavailable — continuing with primary review."

  Degradation matrix: Both fail → "single-reviewer mode". Codex only → tag [codex-only]. Subagent only → tag [subagent-only].

• Strategy choices: if codex disagrees with a premise or scope decision with valid strategic reason → TASTE DECISION. If both models agree the user's stated structure should change (merge, split, add, remove) → USER CHALLENGE (never auto-decided).

Required execution checklist (CEO):

Step 0 (0A-0F) — run each sub-step and produce:

• 0A: Premise challenge with specific premises named and evaluated
• 0B: Existing code leverage map (sub-problems → existing code)
• 0C: Dream state diagram (CURRENT → THIS PLAN → 12-MONTH IDEAL)
• 0C-bis: Implementation alternatives table (2-3 approaches with effort/risk/pros/cons)
• 0D: Mode-specific analysis with scope decisions logged
• 0E: Temporal interrogation (HOUR 1 → HOUR 6+)
• 0F: Mode selection confirmation

Step 0.5 (Dual Voices): Run Claude subagent (foreground Agent tool) first, then Codex (Bash). Present Codex output under CODEX SAYS (CEO — strategy challenge) header. Present subagent output under CLAUDE SUBAGENT (CEO — strategic independence) header. Produce CEO consensus table:

CEO DUAL VOICES — CONSENSUS TABLE:
═══════════════════════════════════════════════════════════════
  Dimension                           Claude  Codex  Consensus
  ──────────────────────────────────── ─────── ─────── ─────────
  1. Premises valid?                   —       —      —
  2. Right problem to solve?           —       —      —
  3. Scope calibration correct?        —       —      —
  4. Alternatives sufficiently explored?—      —      —
  5. Competitive/market risks covered? —       —      —
  6. 6-month trajectory sound?         —       —      —
═══════════════════════════════════════════════════════════════
CONFIRMED = both agree. DISAGREE = models differ (→ taste decision).
Missing voice = N/A (not CONFIRMED). Single critical finding from one voice = flagged regardless.

Sections 1-10 — for EACH section, run the evaluation criteria from the loaded skill file:

• Sections WITH findings: full analysis, auto-decide each issue, log to audit trail
• Sections with NO findings: 1-2 sentences stating what was examined and why nothing was flagged. NEVER compress a section to just its name in a table row.
• Section 11 (Design): run only if UI scope was detected in Phase 0

Mandatory outputs from Phase 1:

• "NOT in scope" section with deferred items and rationale
• "What already exists" section mapping sub-problems to existing code
• Error & Rescue Registry table (from Section 2)
• Failure Modes Registry table (from review sections)
• Dream state delta (where this plan leaves us vs 12-month ideal)
• Completion Summary (the full summary table from the CEO skill)

PHASE 1 COMPLETE. Emit phase-transition summary:

Phase 1 complete. Codex: [N concerns]. Claude subagent: [N issues]. Consensus: [X/6 confirmed, Y disagreements → surfaced at gate]. Passing to Phase 2.

Do NOT begin Phase 2 until all Phase 1 outputs are written to the plan file, including the premise assessment (queued premise challenges travel to the Final Gate — they never pause the pipeline here).
