/erne-learn — Generate Skills from Session

You are executing the /erne-learn command. This is script-driven — it runs the continuous-learning-v2 pipeline directly.

What This Does

Analyzes the current coding session to extract reusable patterns and save them as skills or rule amendments for future sessions. This is the manual trigger for what PostToolUse hooks do automatically.

Process

1. Run the extraction script:

node .claude/hooks/scripts/extract-session-patterns.js

This script:

• Scans recent tool calls and file changes
• Identifies patterns (repeated fixes, style corrections, common architectures)
• Compares against existing rules and skills
• Generates candidates for new content

2. Review candidates: The script outputs a list of potential learnings:

[PATTERN] Zustand store always uses immer middleware → Suggest rule amendment
[PATTERN] All screens use SafeAreaView wrapper → Suggest coding-style rule
[PATTERN] API calls always retry 3 times → Suggest pattern rule
[SKILL] Complex form validation flow → Suggest skill creation

3. Approve or reject each candidate: For each candidate, decide:

• Approve → Script writes to .claude/rules/ or .claude/skills/
• Reject → Skip this pattern
• Edit → Modify before saving

4. Validate new content:

node .claude/hooks/scripts/validate-content.js

Ensures new rules/skills have valid frontmatter and don't conflict with existing content.

When to Use

• After a long coding session where you established new patterns
• When you notice yourself repeatedly making the same corrections
• After integrating a new library and establishing conventions
• Periodically to capture accumulated project knowledge

Note

The automatic PostToolUse hook (continuous-learning-v2.cjs) does lightweight extraction after every tool call. This /erne-learn command runs a comprehensive analysis that catches patterns the real-time hook might miss.
