OpenSpec New Change

The bootstrap step of an OpenSpec change. Sets up structure; content fills in the next step (openspec-continue-change).

Scaffolded structure

openspec/changes/<slug>/
├── proposal.md                 # 30-second readout: why + scope + stage + DoD
├── design.md                   # technical approach + 合规设计说明
├── specs/
│   └── index.md                # spec id table; one row per shippable behavior
├── tasks.md                    # task list (filled by task-decomposition next)
├── COMPLIANCE_TAG.md           # signed at Step 0 (link or copy)
└── MODEL_ALLOWLIST.json        # active at Step 0

Workflow

1. Derive slug — from the PRD stage name (中文允许，URL-safe optional).
2. Initialize — create directory + 4 skeleton files.
3. Fill proposal — pull from PRD §1, §3, §5 (for the relevant stage).
4. Fill design — leave technical body for openspec-continue-change; must include ## 合规设计说明 section now (data tier, PHI flow, model allowlist summary).
5. Init specs — table with at least 1 placeholder row; spec ids of form S<n>-<short>.
6. Init tasks — empty list; task-decomposition fills it.
7. Sanity — all references resolve (PRD path, COMPLIANCE_TAG path).

Compliance Design section template

## 合规设计说明

- 数据等级: <L1/L2/L3/L4>（引用 COMPLIANCE_TAG.md §2）
- PHI 流向: <从哪到哪到哪>（如适用）
- 模型 allowlist: <coder/reviewer/architect 选型摘要，详见 MODEL_ALLOWLIST.json>
- 跨境数据: 是 / 否（如是，必须额外说明绕开方式）
- 新增 prompt 注入面: 是 / 否（如是，列出 RAG/工具/外部输入路径）

Common failure modes

1. Missing COMPLIANCE_TAG link — design.md 写出来后才发现忘了合规章节。修：本 skill 强制建出该 section。
2. Slug over-engineering — omni-agent-os-stage-3-orchestrator-minimal-execution-v2-redux 太长。修：保持简短可识别。
3. Specs without rows — index.md 留空。修：至少给 1 个占位 spec id。
