Extract Learnings

Capture reusable knowledge from completed work into .feature-radar/specs/.

Deep Read

<HARD-GATE> Read and follow `../feature-radar/references/DEEP-READ.md` — complete all 6 steps before proceeding. </HARD-GATE>

Workflow

1. Identify the source — ask the user what was just completed (feature, bug fix, refactor, investigation)
2. Analyze the work — review recent commits, changed files, and implementation decisions
3. Extract knowledge — identify what's reusable:
   • Patterns: recurring solutions worth replicating (e.g., "three-tier config merge")
   • Decisions: architectural choices with rationale (e.g., "YAML over JSON because...")
   • Pitfalls: mistakes or dead ends others should avoid
   • Techniques: implementation approaches that worked well <HARD-GATE>

Before writing to specs/, classify each piece of knowledge into exactly one category:

• Pattern: recurring solution worth replicating
• Decision: architectural choice with rationale
• Pitfall: mistake or dead end to avoid
• Technique: implementation approach that worked well

State the classification explicitly in your output. </HARD-GATE>

4. Write to specs — create or append to .feature-radar/specs/{topic}.md
5. Checkpoint — State what was written and ask: "I've written to specs/{topic}.md ({classification type}). Does this look correct, or should I adjust anything?" Wait for user confirmation before proceeding.
6. Update base.md — increment the specs count in Tracking Summary

File Format

Use the format defined in ../feature-radar/references/SPEC.md § 3.4 (specs/{topic}.md).

Guidelines

• One topic per file. If the learning spans multiple topics, create multiple files.
• Name files by the pattern, not by the feature that produced it.
  • Good: yaml-config-merge.md, symlink-vs-copy-tradeoffs.md
  • Bad: audit-feature-learnings.md, v2-refactor-notes.md
• Append to existing files when the new learning extends a known topic.
• Keep it concise — future readers need the insight, not the full story.

Example Output

→ Created specs/symlink-vs-copy-tradeoffs.md (Decision)
→ Updated base.md: specs 2 → 3
