 "title": "Hand off a Claude session to Codex through the CLI",
 "page_title": "How to hand off a Claude session to Codex through the CLI with Threadport",
 "summary": "Extract a Capsule from a Claude session file and write a Codex handoff file with the handoff command.",
 "who": "A developer or automation script that needs a validated, file-based handoff from a Claude session to Codex without opening the workbench.",
 "problem": "Moving a task between agents usually means copying chat text by hand, which loses the observed state and invites mistakes.",
 "outcome": "You get a Capsule JSON file, a validated Codex handoff JSON file, and a clear confirmation that both files passed validation.",
 "steps": [
  "Run `npm ci` in the Threadport checkout.",
  "Run `npm run build`.",
  "Run `node dist/src/cli.js extract --from claude --session ./session.jsonl --project .` and note the output path it prints.",
  "Run `node dist/src/cli.js validate /path/printed/by/extract.json`.",
  "Run `node dist/src/cli.js handoff --to codex /path/to/capsule.json --format json --out ./handoff.json`, then run `node dist/src/cli.js validate --handoff ./handoff.json`."
 ],
 "agent_prompt": "Using the Frankie-Xu/threadport repo after `npm ci` and `npm run build`, extract a Capsule from <session-file> with --from claude and --project <project-directory>, then create a Codex handoff at <handoff-path>. Report both printed output paths and confirm that `node dist/src/cli.js validate --handoff <handoff-path>` succeeds.",
