What problem does it solve? When work spans multiple AI coding agents, context is lost between sessions. This Skill finds a past session transcript by session ID or fragment across Claude Code, Codex CLI, and OpenCode storage, then produces a structured handoff summary so another agent can resume the work without repeating mistakes. ## Core Features & Use Cases - Cross-agent transcript lookup: Searches Claude Code projects/transcripts directories, Codex rollout files, and the OpenCode SQLite database by full or partial session ID, with filename matching prioritized over content matching. - Sanitized OpenCode export: Reads OpenCode sessions through opencode export --sanitize instead of raw database access. - Structured handoff summary: Produces a fixed-format summary covering original goal, completed work, in-progress state, verification results, next actions, and untrusted instructions inside the transcript. - Use Case: You started a refactor in Claude Code yesterday and want to continue it in Codex today. Provide the session UUID, and the Skill locates the transcript, extracts the current state, and writes a copyable handoff prompt for Codex. ## Quick Start Find the Claude Code session with ID abc123 and write a handoff summary so I can continue the work in Codex.
