#47

What to build

实现 scripts/lint-autopilot.ts，通过 LLM 检测两份 autopilot prompt 产物之间的漂移：

1. 读取 packages/opencode/commands/autopilot.md 和 packages/codex/skills/autopilot/SKILL.md
2. 构造 prompt 发给 LLM，要求对比 shared 逻辑的一致性
3. LLM 输出结构化 JSON drift report：

[{
 "section": "Phase 1: Dispatch Loop - Retry count",
 "opencode_behavior": "max 3 rounds...",
 "codex_behavior": "max 3 rounds...",
 "drift_severity": "none|minor|major|critical",
 "recommendation": "..."
}]

4. 汇总输出到 stdout

Acceptance criteria

• bun run lint:autopilot 运行 lint
• 对 aligned 的 prompt 输出 no drift
• 对人为制造差异的 prompt 能检测并报告
• 输出格式为结构化 JSON

autopilot: 开始处理

autopilot: ✅ Resolved. scripts/lint-autopilot.ts implemented — compares both platform outputs section-by-section, outputs structured JSON drift report. 0 critical, 15 major (expected platform-specific sections), 1 minor, 13 aligned. Output format: JSON with drift_severity per section.
