✅ Checks:
- Specific action verbs (create, fix, add, update)
- Technical specifics (function, class, file, API)
- Concrete targets (file paths, code elements)

❌ Concerns:
- Vague verbs (improve, optimize, enhance)
- Too brief (<5 words)
- Missing technical details

Score: 0.0 - 1.0
Weight: 50% (most important)

✅ Checks:
- Load Reflexion memory
- Search for similar past failures
- Keyword overlap detection

❌ Concerns:
- Found similar mistakes (score -= 0.3 per match)
- High recurrence count (warns user)

Score: 0.0 - 1.0
Weight: 30% (learn from history)

✅ Checks:
- Essential context loaded (project_index, git_status)
- Project index exists and fresh (<7 days)
- Sufficient information available

❌ Concerns:
- Missing essential context
- Stale project index (>7 days)
- No context provided

Score: 0.0 - 1.0
Weight: 20% (can load more if needed)
