From intent to mission

Launch turns a plain-language request into a reviewed mission. A planner drafts the work; you see what would run before approving it.

The flow

  1. Write what should happen and why in a Markdown request.
  2. Start a planning conversation.
  3. Let the planner draft a description and mission KDL.
  4. Preview the exact candidate, including dependencies, changes, warnings, and blockers.
  5. Give feedback or compare variants.
  6. Approve publication, or deliberately approve and launch.
fractal launch start --id release-mission request.md --workspace ./project --as person/ada
fractal launch ls

Use the returned session ID with fractal launch show SESSION and fractal launch preview SESSION. fractal launch revise SESSION feedback.md --as person/ada requests a new candidate. Consult each command's --help for approval options and the preview token it requires.

Approval is tied to the current preview. If the candidate changes after review, review it again rather than approving unseen work. Publication alone does not start a run; approve-and-launch explicitly requests both.

Durable planning

The request, candidates, feedback, preview, and decision are graph state, not a temporary chat transcript. Launch can also propose a new generation for an existing run without silently replacing its current plan.

Approvals appear in Now. For exact command options, see CLI reference.
