fleet

A coordinator for splitting a large coding task into several independent work streams that run in parallel. It gives each stream an isolated worktree, which is a separate copy of the repository’s files for making changes safely.

In plain words
What is it for?
Use it for projects with at least three separate tasks that can proceed independently. It can run coordinated waves, collect results, share context, and support different approaches to the same task.
Why use it?
It reduces waiting when different parts of a task can be handled at the same time. It also carries findings from earlier groups of work into later groups.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fleet scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 310 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/fleet — Parallel Coordinator

Use for 3+ independent work streams that can run simultaneously in isolated worktrees. Do NOT use for single-file scope, linear work, or when a marshal or skill suffices.

Orientation

Use when: Running 2+ independent work streams in parallel — tasks with non-overlapping file scopes that can execute simultaneously.

Don't use when: Work must execute sequentially or accumulate findings across phases (use /archon), a single orchestrated session is enough (use /marshal), or the task is simple enough for a bare skill.

Commands

Command Behavior
/fleet [direction] Decompose direction into parallel streams, execute in waves
/fleet [path-to-spec] Read a spec file, decompose into streams
/fleet continue Resume from the last fleet session file
/fleet (no args) Health diagnostic → work queue → execute
/fleet --quick [task1]; [task2] Lightweight parallel mode for solo devs — 2+ tasks, single wave, governed merge, minimal durable receipt
/fleet --speculative N [direction] Try N different approaches to the same task in parallel — see Speculative Mode below
/fleet --teams [direction] Pilot: native task spine when CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS is set, see Teams Mode (experimental) below

Protocol

Step 1: WAKE UP

  1. Read CLAUDE.md (project conventions)
  2. Check .planning/campaigns/ for active campaigns
  3. Check .planning/coordination/claims/ for external claims
  4. Determine input mode: directed, spec-driven, continuing, or undirected
  5. Load prior session context: if .planning/momentum.json exists, run node .citadel/scripts/momentum-read.cjs and use the active scopes and recurring decisions to inform work queue prioritization. Skip silently if the file is absent or output is empty.

Wave context restoration: Use the Claude Code Compaction API to restore fleet session context. Do NOT read .claude/compact-state.json — deprecated in favour of server-side compaction (available on Opus 4.6+). Fleet session files (.planning/fleet/session-{slug}.md) remain the source of truth for inter-wave discovery relay; compaction handles agent memory, not campaign state. If the Compaction API is unavailable, read the fleet session file's Continuation State directly.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

fleet is a skill published in the GitHub repository SethGammon/Citadel (914 stars, last pushed 6d ago), licensed MIT. It adds 56 tokens to every session and 5,580 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
