Project Discovery | 專案現況評估

Phase 0 assessment before adding features to existing codebases. Evaluate project health, architecture, and risks.

在既有程式碼庫新增功能前的 Phase 0 評估。評估專案健康度、架構與風險。

Assessment Dimensions | 評估維度

Dimension	What to Check	檢查項目
Architecture	Module structure, dependency graph, entry points	模組結構、相依圖、進入點
Dependencies	Outdated packages, known vulnerabilities, license risks	過時套件、已知漏洞、授權風險
Test Coverage	Existing test suite, coverage gaps, test quality	現有測試、覆蓋率缺口、測試品質
Security	npm audit findings, hardcoded secrets, exposed endpoints	安全稽核、硬編碼密鑰、暴露端點
Technical Debt	TODOs, code duplication, complexity hotspots	TODO 標記、程式碼重複、複雜度熱點

Workflow | 工作流程

1. Scan project - Read package.json, directory structure, config files
2. Analyze architecture - Map modules, dependencies, and data flow
3. Check dependencies - Run npm outdated, npm audit for health signals
4. Assess risks - Identify complexity hotspots, missing tests, security issues
5. Generate report - Output health score with actionable recommendations

Project Health Report
=====================
Overall Score: 7.2 / 10

| Dimension       | Score | Status  | Key Finding            |
|-----------------|-------|---------|------------------------|
| Architecture    | 8/10  | Good    | Clean module boundaries |
| Dependencies    | 6/10  | Warning | 5 outdated, 1 critical |
| Test Coverage   | 7/10  | Fair    | 72% line coverage      |
| Security        | 8/10  | Good    | No critical vulns      |
| Technical Debt  | 6/10  | Warning | 23 TODOs, 3 hotspots   |

Recommendations:
1. [HIGH] Update lodash to fix CVE-2024-XXXX
2. [MED]  Add tests for src/payments/ (0% coverage)
3. [LOW]  Resolve TODO backlog in src/utils/

Risk Register | 風險登記簿

After assessment, identified risks are recorded in a structured Risk Register for ongoing tracking.

評估完成後，已識別的風險記錄在結構化的風險登記簿中進行持續追蹤。

Risk Matrix | 風險矩陣

              Impact | 影響
         Low    Med    High
High   [ Med ] [High] [Crit]
Med    [ Low ] [Med ] [High]   Likelihood | 可能性
Low    [ Low ] [Low ] [Med ]

Next Steps Guidance | 下一步引導

After /discover completes, the AI assistant should suggest based on the assessment:

根據評估結果，建議下一步 / Based on assessment, suggested next steps:

• New feature / 新功能 → /sdd to create a specification ⭐ Recommended / 推薦
• Legacy code / 遺留程式碼 → /reverse spec to extract existing behavior
• Refactoring / 重構 → /refactor decide to choose a strategy
• Quick fix / 快速修復 → /tdd to write a targeted test and fix
• Risk tracking / 風險追蹤 → /discover --risks to view risk register
• Architecture decision / 架構決策 → /adr to record decisions made during discovery
