cagent

cagent is a skill for Claude Code from Tyler-R-Kendrick/agent-skills. It costs 94 tokens per session (1,251 once invoked), scanned A, original, MIT.

A Docker-based runtime for defining and running teams of AI agents. Agents and their tools are described in YAML files.

In plain words
What is it for?
Use it to build multi-agent systems, configure agent teams, connect MCP tools, and run them locally through the cagent command-line tool.
Why use it?
It provides one local way to coordinate several agents, connect them to tools, and manage their roles and sub-agents.

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

cagent 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 11d 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.

cagent — Docker Agent Runtime

Overview

cagent is an open-source multi-agent runtime from Docker that lets you define, orchestrate, and run teams of AI agents. Agents are configured in YAML with specialized capabilities, tools, and sub-agents. cagent supports MCP for tool integration, the Agent Client Protocol (ACP) for IDE integration, and runs locally via cagent run. Bundled in Docker Desktop.

Installation

# Bundled with Docker Desktop, or install standalone:
brew install docker/tap/cagent     # macOS
# Or download from github.com/docker/cagent/releases

Agent Configuration

Agents are defined in a cagent.yaml file:

version: "2"

agents:
  root:
    model: anthropic/claude-sonnet-4-5-20250929
    description: A helpful AI assistant with search and file access
    instruction: |
      You are a knowledgeable assistant that helps users with various tasks.
      Be helpful, accurate, and concise in your responses.
      Write your results to disk.
    toolsets:
      - type: mcp
        ref: docker:duckduckgo
      - type: mcp
        command: rust-mcp-filesystem
        args: ["--allow-write", "."]
        tools: ["read_file", "write_file"]

Model Configuration

Define models inline or as named references:

version: "2"

models:
  fast:
    provider: openai
    model: gpt-5-mini
    max_tokens: 4096
  strong:
    provider: anthropic
    model: claude-sonnet-4-5-20250929
    max_tokens: 64000

agents:
  root:
    model: strong
    description: Main orchestrator
    sub_agents: [researcher, writer]

  researcher:
    model: fast
    description: Finds information
    toolsets:
      - type: mcp
        ref: docker:duckduckgo

  writer:
    model: strong
    description: Writes polished content

MCP Tool Integration

Docker MCP Gateway

Use containerized MCP servers via Docker's MCP Gateway:

toolsets:
  - type: mcp
    ref: docker:duckduckgo      # Search
  - type: mcp
    ref: docker:fetch           # HTTP fetch
  - type: mcp
    ref: docker:github          # GitHub API

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.

cagent is a skill published in the GitHub repository Tyler-R-Kendrick/agent-skills (11 stars, last pushed 3mo ago), licensed MIT. It adds 94 tokens to every session and 1,251 once invoked, about $0.0005 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 2026-08-31.
