create-agent

create-agent is a skill for Claude Code, Codex from openma-ai/open-managed-agents. It costs 90 tokens per session (805 once invoked), scanned A, original, Apache-2.0.

A conversational setup skill for openma, an open-source platform that builds and runs AI agents. It helps define an agent’s model, instructions, tools, and connections to outside services.

In plain words
What is it for?
Use it when creating an openma agent for coding, research, data analysis, customer support, or automation. It can guide choices about the task, model, tools, credentials, and deployment.
Why use it?
It turns a loosely described automation idea into an agent configuration without requiring the user to know the platform’s setup process.

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

create-agent 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.

openma Agent Creator

What is openma?

openma is an open-source platform for building, deploying, and managing AI agents. Think of it as a managed runtime — you define an agent (model + system prompt + tools), the platform handles sandboxed execution, credential management, and session state.

What you can do with it:

  • Build agents for any task: coding, research, data analysis, customer support, automation
  • Run agents in sandboxes — each session gets an isolated container with file system, shell, and network
  • Connect external services via MCP servers (GitHub, Slack, Linear, Notion, etc.) with OAuth
  • Use any LLM — Anthropic, OpenAI, DeepSeek, or any OpenAI-compatible provider
  • Install community skills from ClawHub to extend agent capabilities
  • Manage credentials securely in vaults — agents get scoped access, secrets never leak
  • Collaborate — multi-user workspace with API key access for CLI/SDK integration

Creating an Agent

Flow

  1. Understand the goal — ask what the agent should do. If vague, one question: "What's the main task?" Two rounds max, then build.

  2. Pick the model — check /v1/model_cards first. Defaults:

    • Complex/coding: claude-opus-4-6
    • General (default): claude-sonnet-4-6
    • Simple/fast: claude-haiku-4-5-20251001
    • OpenAI: gpt-4o, o3
  3. Write system prompt — specific, actionable, bounded. Not generic.

  4. Select tools — default agent_toolset_20260401 (file ops, bash, web) covers most cases.

  5. Create:

    POST /v1/agents
    { "name", "model", "system", "tools": [{"type":"agent_toolset_20260401"}] }
    
  6. Next steps — offer to create session, configure skills, set up model card.

Platform Quick Ref

Agents need a session to run. Sessions need an environment (sandbox).

Resource What it is
Agent Model + system prompt + tools config
Session A conversation with an agent in a sandbox
Environment Sandbox runtime (default works for most)
Model Card API key + provider config for an LLM
Vault Secure credential storage for MCP/CLI secrets
Skill SKILL.md that gives agents domain expertise
API Key Programmatic access token for CLI/SDK

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.
