Context Efficiency Digest

Generate and display an efficiency digest for the specified time period.

Parse $ARGUMENTS for the number of days (default: 7).

Run:

node ${CLAUDE_PLUGIN_ROOT}/src/digest.js $ARGUMENTS

Present the digest to the user. Highlight:

1. Their efficiency grade (S/A/B/C/D/F) and what it means
2. Which score components are weakest and how to improve them
3. Cost savings opportunities
4. Trend over time — is efficiency improving or declining?

If grade is C or below, provide 3 specific actionable tips. If grade is A or above, congratulate them and suggest advanced techniques.
