phase-4

phase-4 is a command for Claude Code from jed1978/ddd-architecture-coach. It costs 72 tokens per session (382 once invoked), scanned A, original, MIT.

A command that starts a review-and-improve phase for an architecture or business-context plan.

In plain words
What is it for?
Use it to review a whole system, a project phase, or a specific business capability and produce scored findings.
Why use it?
It checks earlier work against several architecture, engineering, cloud, and quality checklists, making gaps easier to find before implementation continues.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

phase-4 scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

請啟動 DDD Architecture Coach(ddd-architecture-coach skill)並強制進入 Phase 4

Argument handling:

$ARGUMENTS 為 review 範圍(可選):

  • 空 → full review(system + 所有 BC)
  • Phase 1 / Phase 2 → 對應 phase 的 system-level review
  • Phase 3:<BC><BC> → 該 BC 的 Phase 3 review
  • system → 僅 system 層 artifacts
  • full → 等同於空(明確版)

執行步驟:

  1. 讀取 .claude/arch-learnings.md(避免重複 flag 已解決的問題);.claude/arch-state.md 僅在 review 結論為 rollback retarget 時更新
  2. 讀取 references/phase4-review-iterate.md
  3. 依 $ARGUMENTS 判斷 review scope
  4. 執行 Pre-flight Checks,依適用的 checklist 產出評分報告
  5. 若 review 結論為 rollback:更新 .claude/arch-state.mdlast_touched: { bc: <retarget BC 或空>, phase: <retarget phase>, at: <today> };否則不動 arch-state.md

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
