Use cases
Green by morning.
Brief the fleet before bed. Six Claude Code sessions write the missing tests module by module, while auto-accept, stall recovery, and account rotation keep them moving all night.
The fan-out
One module per session.
Split by module
The Conductor reads your goal and assigns each untested area, parsers, billing, API routes, to its own session in the mission DAG. No session waits on another's files.
Write, run, fix
Each session is the real Claude Code CLI in a real terminal. It writes the tests, runs them, and reworks what fails before moving on.
Counted when verified
A task is not done because a session said so. Loom re-checks the work before it counts, so a premature done gets caught instead of slipping into the suite.
Overnight
Nothing waits for you at 3 am.
Claude Code asks before edits and commands, and auto-accept presses only the safe affirmative so no terminal sits on a prompt while you sleep. Usage limits park the account and rotate to the next pooled login, a watchdog nudges sessions that drift, and exited CLIs are relaunched with their task re-sent.
# the goal you type
$ Cover parsers/, billing/, and api/ with unit tests
# what keeps the run alive
# permission prompt: safe affirmative pressed
# usage limit: account parked, next rotated in
# stalled or exited session: nudged or relaunchedQuestions
Test sweeps with a fleet.
Does the fleet need an API key?
No. The six sessions run on your existing Claude login through the official CLI. Only the Conductor, the planning model, is bring-your-own-key, and it can even run locally.
What do I do in the morning?
Review. The source control panel shows every change with a full git graph, and the editor lets you accept or reject edits hunk by hunk. Reviewing fleet work walks through it.
Is auto-accept safe to leave on overnight?
It only presses the safe affirmative on Claude Code's own prompts, and it is toggleable. Shift+tab cycles a single terminal's permission mode if you want one session held to a stricter standard. Details under auto-accept.
