# Context Heatmap

Show the user a visual heatmap of their context usage in the current session.

Run the following command to get the current session's tracking data (uses the most recent session automatically):

```bash

node ${CLAUDE_PLUGIN_ROOT}/src/tracker.js heatmap

```

If no data is available yet (empty session), tell the user:

- "No context data tracked yet in this session. Keep working and the optimizer will track file reads, edits, and searches automatically."

+ "No data in this session yet. Just keep working — the optimizer tracks your reads, edits, and searches automatically!"

Present the heatmap output to the user and highlight:

1. Files marked with a warning icon that were read but never used — suggest avoiding them next time

2. Files marked with an edit icon that were actually edited — these are high-value context

3. The total estimated token usage and waste percentage

If waste is over 30%, suggest specific ways to reduce it based on the files shown.
