Plan Flow

Overview

Use this skill when the user needs:

• A complete analysis of duplicated/redundant design in a codebase.
• A detailed TODO plan with explicit file-level steps.
• Strict execution evidence: change one step, test it, then update plan status.

This skill is repository-agnostic. It defines how to analyze and plan, not only what was done in one specific repo.

Core Workflow (Analyze -> Plan -> Execute)

1. Establish scope and constraints.

• Confirm target directories/modules and out-of-scope areas.
• Capture compatibility requirement, risk tolerance, and testing expectations.
• Record baseline (git status --short, current branch, known blockers).

2. Run structured redundancy analysis first.

• Build an inventory of architecture anchors:
  • Domain models and schemas
  • Factory/registry entry points
  • HTTP/storage/cache/logging abstractions
  • Route/service/provider adapters
• Identify duplicate/redundant candidates with evidence:
  • Same concept, multiple conflicting definitions
  • Same responsibility, parallel implementations
  • Exported but unconnected modules
  • Dead/legacy paths still affecting readability
• For each finding, record:
  • Exact files and symbols
  • Call path or usage evidence
  • Risk if changed
• See references/analysis-playbook.md.

3. Prioritize and convert analysis into executable plan.

• Score each finding by impact/effort/risk/confidence.
• Group into phases (P0, P1, P2) and sequence low-risk/high-signal steps first.
• Create or update plan/<task>.md from references/plan-template.md.
• Keep exactly one step in in_progress.
• Use statuses: pending / in_progress / completed / blocked.
• See references/risk-impact-scoring.md.

4. Execute with strict step-test-update loop.

• Implement only the current step and only in listed files.
• Run step-level tests immediately, then project health checks.
• Update plan status and execution log before touching next step.
• On failure, record root cause and run fix loop before continuing.

5. Close with phase/final verification.

• Run phase matrix checks and final regression set.
• Report residual risks, deferred work, and explicit coverage gaps.

Quality Gates

• No finding enters the plan without file-level evidence.
• No step is completed without test command evidence.
• No next step starts before plan status/log update is written.
• If full regression is unavailable, record exact reason and nearest fallback checks.

Reference Map

• references/analysis-playbook.md
  • How to detect duplicate/redundant design with reproducible evidence.
• references/risk-impact-scoring.md
  • How to prioritize findings into phases and step order.
• references/plan-template.md
  • Reusable plan skeleton including analysis table, step template, and log format.
• references/plan-accomplishments.md
  • One completed real example (for style and granularity only, not as mandatory scope).

Scripts

• scripts/redundancy_scan.sh <target_dir>
  • Fast first-pass scan for duplicate symbol names, parallel factory/builders, and legacy/dead-code hints.
• scripts/findings_to_plan.py --target-dir src --output plan/<name>.md
  • Convert scan findings into a draft execution plan with scoring and phased order (P0/P1/P2).
• scripts/plan_lint.py <plan/file.md>
  • Validate plan state machine, test evidence, and execution-log completeness for completed steps.

Trigger Cues

Trigger this skill when user asks for:

• "分析这个库有哪些重复设计/冗余设计"
• "做一个非常完整详细的 todolist/执行计划"
• "每改一处就测试并更新计划状态"
• "按步骤推进并可追踪"

Execution Rules

• Prefer small, reversible steps over large refactors.
• Keep plan language specific to file paths, symbols, and commands.
• Avoid mixing analysis conclusions with unverified assumptions.
• If new evidence contradicts earlier assumptions, revise plan before coding.
