Implementation Plan Creation

create an implementation plan in docs/plans/yyyymmdd-<task-name>.md with interactive context gathering.

step 0: parse intent and gather context

before asking questions, understand what the user is working on:

1. parse user's command arguments to identify intent:

   • "add feature Z" / "implement W" → feature development
   • "fix bug" / "debug issue" → bug fix plan
   • "refactor X" / "improve Y" → refactoring plan
   • "migrate to Z" / "upgrade W" → migration plan
   • generic request → explore current work

2. gather relevant context quickly — use direct spring-explore skill, NOT an Explore agent. keep discovery under 30 seconds:

   CRITICAL: do NOT launch an Explore agent. the goal is a quick scan, not exhaustive analysis. if more context is needed, ask the user in step 1.
