What problem does it solve?

Claude Code session transcripts can be verbose and difficult to parse, making it hard to quickly review past interactions, understand tool usage, or analyze workflow patterns. This Skill automates the condensation of these logs, transforming raw data into actionable insights.

Core Features & Use Cases

• Human-Readable Summaries: Condenses lengthy transcripts into clear Markdown or structured JSON, filtering out noise like metadata and system messages.
• Workflow Analysis: Easily identify tool usage patterns, subagent interactions, and key events to understand how tasks were executed.
• Customizable Output: Choose verbosity levels (minimal, standard, detailed) and filter options (tool-only, subagent-only) to focus on what matters most.
• Batch Processing: Process entire directories of transcripts, generating consistent reports for multiple sessions.
• Use Case: Quickly review your last 5 Claude Code sessions to see which tools were most effective, identify common errors, and pinpoint areas for workflow optimization.
