claude-devfleet

claude-devfleet is a skill for Claude Code from KratosAR/claude-code-arsenal. It costs 36 tokens per session (1,382 once invoked), scanned A, a copy of claude-devfleet, MIT.

A coordinator for assigning coding work to multiple Claude Code agents. It breaks projects into dependent missions, runs agents in separate Git worktrees, and tracks their reports.

In plain words
What is it for?
It helps plan projects, create and dispatch missions, run dependent tasks, merge completed work, and review reports about changed files and errors.
Why use it?
It helps split large coding tasks into parallel or ordered pieces while keeping each agent's changes isolated. This reduces collisions between agents and makes progress easier to monitor.

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

claude-devfleet 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 5d 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.

Claude DevFleet Multi-Agent Orchestration

When to Use

Use this skill when you need to dispatch multiple Claude Code agents to work on coding tasks in parallel. Each agent runs in an isolated git worktree with full tooling.

Requires a running Claude DevFleet instance connected via MCP:

claude mcp add devfleet --transport http http://localhost:18801/mcp

How It Works

User → "Build a REST API with auth and tests"
  ↓
plan_project(prompt) → project_id + mission DAG
  ↓
Show plan to user → get approval
  ↓
dispatch_mission(M1) → Agent 1 spawns in worktree
  ↓
M1 completes → auto-merge → auto-dispatch M2 (depends_on M1)
  ↓
M2 completes → auto-merge
  ↓
get_report(M2) → files_changed, what_done, errors, next_steps
  ↓
Report back to user

Tools

Tool Purpose
plan_project(prompt) AI breaks a description into a project with chained missions
create_project(name, path?, description?) Create a project manually, returns project_id
create_mission(project_id, title, prompt, depends_on?, auto_dispatch?) Add a mission. depends_on is a list of mission ID strings (e.g., ["abc-123"]). Set auto_dispatch=true to auto-start when deps are met.
dispatch_mission(mission_id, model?, max_turns?) Start an agent on a mission
cancel_mission(mission_id) Stop a running agent
wait_for_mission(mission_id, timeout_seconds?) Block until a mission completes (see note below)
get_mission_status(mission_id) Check mission progress without blocking
get_report(mission_id) Read structured report (files changed, tested, errors, next steps)
get_dashboard() System overview: running agents, stats, recent activity
list_projects() Browse all projects
list_missions(project_id, status?) List missions in a project

Note on wait_for_mission: This blocks the conversation for up to timeout_seconds (default 600). For long-running missions, prefer polling with get_mission_status every 30–60 seconds instead, so the user sees progress updates.

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.
