/learn - Extract Reusable Patterns

Analyze the current session and extract any patterns worth saving as skills.

Trigger

Run /learn at any point during a session when you've solved a non-trivial problem.

What to Extract

Look for:

1. Error Resolution Patterns

   • What error occurred?
   • What was the root cause?
   • What fixed it?
   • Is this reusable for similar errors?

2. Debugging Techniques

   • Non-obvious debugging steps
   • Tool combinations that worked
   • Diagnostic patterns

3. Workarounds

   • Library quirks
   • API limitations
   • Version-specific fixes

4. Project-Specific Patterns

   • Codebase conventions discovered
   • Architecture decisions made
   • Integration patterns

Output Format

Create a skill file at ~/.claude/skills/learned/[pattern-name].md:

# [Descriptive Pattern Name]

**Extracted:** [Date]
**Context:** [Brief description of when this applies]

## Problem

[What problem this solves - be specific]

## Solution

[The pattern/technique/workaround]

## Example

[Code example if applicable]

## When to Use

[Trigger conditions - what should activate this skill]

Process

1. Review the session for extractable patterns
2. Identify the most valuable/reusable insight
3. Draft the skill file
4. Ask user to confirm before saving
5. Save to ~/.claude/skills/learned/

Notes

• Don't extract trivial fixes (typos, simple syntax errors)
• Don't extract one-time issues (specific API outages, etc.)
• Focus on patterns that will save time in future sessions
• Keep skills focused - one pattern per skill
