Do I need a Claude API key to use this skill?

The 'Analyze' mode requires the Claude CLI to be configured, but the 'Stats Only' mode works locally on your session logs without additional API calls.

Where does the tool find my Claude Code logs?

It automatically scans the default ~/.claude/projects/ directory where the Claude CLI stores session history.

What does a score of 100 represent?

A perfect score indicates a session with zero waste, where the AI used the minimum necessary tokens and steps to complete the user's request accurately.

How does Session Evaluator help reduce API costs?

It identifies redundant file reads and unnecessary context bloat, helping you refine your prompts to minimize token consumption.

分析と監視

Analyzes and scores Claude Code session efficiency to reduce token waste and optimize AI development workflows.

Session Evaluator is a specialized web-based tool designed to audit Claude Code interactions by analyzing session logs (JSONL). It evaluates AI behavior across seven key dimensions—including token efficiency, task relevance, and error recovery—to provide a detailed performance score out of 100. By identifying redundant file reads, unnecessary context bloat, and suboptimal model selections, this skill helps developers refine their AI configurations and prompts to achieve leaner, more cost-effective, and faster development cycles.
