knowledge

# Knowledge

Display the current state of the project's knowledge base and recent learnings.

## What This Does

Shows:
- Learning mode status (on/off)
- Knowledge base statistics (entry counts per category)
- Recent learnings extracted
- Cache statistics

## Instructions

1. Read `knowledge/state.json` for learning mode status
2. Read each knowledge file and count entries:
   - `knowledge/cache/classifications.md`
   - `knowledge/learnings/patterns.md`
   - `knowledge/learnings/quirks.md`
   - `knowledge/learnings/decisions.md`
3. Extract recent entries (last 5) from learnings files
4. Format and display

## Output Format

📊 Knowledge Statistics
───────────────────────────────────────────────────
Knowledge base is empty.

💡 Get Started
───────────────────────────────────────────────────
Use /learn to extract insights from your current session.
Use /learn-on to enable continuous learning.

The knowledge base will grow as you work, capturing:
  - Patterns that work well in this project
  - Quirks and gotchas to remember
  - Decisions and their rationale
```

## Steps

1. Read `knowledge/state.json`
2. Read frontmatter from each knowledge file to get entry counts
3. Parse recent entries from learnings files (look for `## Pattern:`, `## Quirk:`, `## Decision:` headers)
4. Format and display the summary
5. If files are missing or empty, show the "empty" state

## Notes

- Entry counts come from frontmatter `entry_count` field or by counting `##` headers
- Recent learnings are shown most recent first (by discovered/made date)
- This is a read-only command - it doesn't modify any files
