What problem does it solve? AI coding sessions in Claude Code and Codex disappear into local logs, making it hard to produce daily reports, technical retrospectives, or reusable documentation of what was investigated, fixed, and left pending. ## Core Features & Use Cases - Current Session Archiving: Summarizes the active conversation into an overview plus an incremental timeline entry, writing summary.md and a styled summary.html with a problem-navigation sidebar under $HOME/文档/AI-Session. - Date-Range Archiving: Collects evidence from local Claude Code JSONL logs and Codex rollout/state databases for today, yesterday, or any date range, then merges findings by project into a single range archive. - Incremental Updates: Rewrites the overview to reflect the latest state while appending only new facts to the call timeline, with Session ID mismatch protection to prevent mixing different sessions. - Use Case: At the end of a debugging day, ask for a range archive of today's sessions to get a report-ready summary with problem details, commands, errors, and follow-ups. ## Quick Start Call the session-technical-summary skill to archive today's AI sessions into a technical summary document.
