Pre-Implementation Checklist
Complete before writing any code.
Phase 1: Understand Context
- Find Related Code:
fs/find, text/ripgrep - list 3-5 relevant files
- Read Philosophy:
code/symbols, code/complexity - patterns, abstractions, anti-patterns
- Semantic Analysis: LSP references, call hierarchy, workspace symbols
Phase 2: Challenge Assumptions
- What problem does this actually solve?
- Is this the simplest solution? (list 2 rejected alternatives)
- What assumptions am I making?
- What could go wrong? (top 3 failure modes)
- What files will I modify/create? What's OUT of scope?
Phase 3: Propose Solution
- 3-5 sentence approach (where logic lives, patterns to follow, reuse vs create)
- Numbered implementation steps
- Test strategy with edge cases
Output Summary
## Pre-Impl Summary: [task]
**Problem:** [one sentence]
**Approach:** [one sentence]
**Key files:** [list]
**Assumptions:** [bullets]
**Risk:** [highest]
Ready to implement: YES/NO
STOP if checklist incomplete - ask questions instead.
