fleet

An orchestration skill that ships several parts of a decomposed product requirements document, or PRD, in parallel using separate Git worktrees. A worktree is an isolated copy of a repository for making changes safely.

In plain words
What is it for?
Use it after decomposition to group non-conflicting features, run implementation work in batches, and merge completed branches back into the main branch.
Why use it?
It reduces waiting when features do not touch the same files and identifies file conflicts before parallel work begins.

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 B, and why

fleet scanned grade B with 1 finding 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 2d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts

The opening of the file, as written. The whole thing — 330 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Orchestrate parallel /ship runs for decomposed PRDs. Analyze file conflicts across features, group non-conflicting features into parallel batches, execute each in an isolated git worktree, and merge results back to main conflict-free.

$ARGUMENTS is optional:

  • First positional arg: decomposition name (matches .claude/specs/decomposition-<name>.md)
  • --dry-run — generate specs and show batch plan, but don't implement
  • --max-parallel N — limit concurrent worktrees (default: 5)
  • --batch-only — run batch 1 only, then stop for review

Architecture

Fleet is a thin orchestrator — it never reads code files or accumulates implementation context. It reads manifests, spec metadata, and delegates all per-feature work to /ship subagents running in isolated worktrees.

Fleet orchestrator (this skill)
  ├── Step 0: load decomposition manifest
  ├── Step 1: collect file claims from specs
  ├── Step 2: conflict analysis → batch plan
  ├── Step 3: execution plan + user approval
  ├── Step 4: batch execution loop
  │     ├── Launch /ship agents in isolated worktrees (background)
  │     ├── Wait for completion
  │     ├── Merge completed branches to main
  │     └── Advance to next batch
  ├── Step 5: final integration verify
  ├── Step 6: failure triage
  └── Step 7: fleet report + metrics

Step 0 — Load decomposition manifest

  1. Parse $ARGUMENTS for the decomposition name and flags (--dry-run, --max-parallel N, --batch-only)
  2. If a decomposition name is provided, read .claude/specs/decomposition-<name>.md
  3. If no name provided, find the most recently modified decomposition-*.md in .claude/specs/
  4. If no decomposition manifest exists: stop — "No decomposition found. Run /decompose first to break your concept into PRDs."
  5. Parse the manifest's features table: extract feature name, PRD path, dependencies, status
  6. Filter to features with status pending only (skip completed, in-progress, skipped)
  7. If no pending features: "All features are already completed or in-progress."

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 dixus/claudeframework (10 stars, last pushed 4mo ago), licensed MIT. It adds 37 tokens to every session and 3,368 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
