description	Write a new Architecture Decision Record (ADR) with auto-numbering
argument-hint	<title>

Write ADR

Create a new Architecture Decision Record in the project's docs/adr/ directory.

Input

$ARGUMENTS — the ADR title (e.g., "使用 sparse matrix 存储表达矩阵"). If not provided, ask.

Workflow

1. Auto-number:

   • Scan docs/adr/ for existing ADRs
   • Next number = max existing + 1, zero-padded to 3 digits

2. Gather context:

   • Ask the user:
     • What decision was made?
     • What alternatives were considered?
     • Why was this option chosen?
   • Read docs/design.md for related context

3. Write the ADR:

   File: docs/adr/<NNN>-<slug>.md

   # ADR-<NNN>: <Title>
   
   **Date:** <today>
   **Status:** Accepted
   
   ## Context
   <What problem or question prompted this decision>
   
   ## Decision
   <What was decided>
   
   ## Alternatives Considered
   <Other options and why they were rejected>
   
   ## Consequences
   <What this means going forward — positive and negative>
   
   ## References
   <Links to issues, papers, docs if relevant>
   

4. Commit:

   • git add docs/adr/<NNN>-<slug>.md
   • Commit with message: docs: add ADR-<NNN> <title>

5. Prompt for design update:

   • Check if the decision affects docs/design.md
   • If yes: "这个决策影响到 design.md，要运行 /swf:update-design 更新吗？"

Rules

• ADRs are append-only: never modify existing ADRs
• If a decision supersedes a previous one, note it in Context and update the old ADR's status to "Superseded by ADR-NNN"
• Must be run from within a project repo directory
