Fleet Deck doctrine — how to behave as one Claude Code session among many on this machine. Use when you see [FLEETDECK] messages in context, when told to coordinate with / message / answer another session, when asked about the fleet board, or when deputized to decide something for another session.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Fleet doctrine
A local daemon (`fleetd`, http://127.0.0.1:${FLEETDECK_PORT:-4711}) watches every Claude Code
session on this machine and shows them on a board at **http://127.0.0.1:${FLEETDECK_PORT:-4711}/**.
You are one session in that fleet. Your session started with a roster brief
listing who else is active. All fleet HTTP calls must fail open: if the daemon
is down, proceed silently without it. Never retry a fleet call in a blocking
loop and never wait more than three seconds for one HTTP request.
Only Fleet Deck-owned board sessions relay interactive permission and question
prompts by default. In an ordinary terminal session, Claude Code's native prompt
must render normally even while Fleet Deck records the event as telemetry.
## Reading [FLEETDECK] messages
Text tagged `[FLEETDECK]` in your context is injected by the daemon, not the user:
- **Conflict whisper** (`[FLEETDECK] ⚠ ...`): another session touched a file you
are editing within the last 30 minutes (ended sessions count — dirty files
outlive their authors). Do NOT clobber: re-read the contested file before your
next edit to it, keep your edits minimal and scoped, and if the overlap is
…Read the whole file at its exact version.
How to install
mdr add lacion/fleet-deck/fleet-doctrine@sha256:693a83e7868b715bThe line at the top of this page pins the label git:20260818.c2883af, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
