openma is a skill for Claude Code, Codex from openma-ai/open-managed-agents. It costs 87 tokens per session (847 once invoked), scanned A, original, Apache-2.0.

An open-source platform for building, deploying, and managing AI agents, including their models, tools, environments, sessions, and credentials.

In plain words
What is it for?
It helps create agents, start and message sessions, manage environments and model settings, store credentials, install skills, connect MCP servers, and use the platform's HTTP API.
Why use it?
It provides one workflow for running agents in sandboxed environments while keeping session state and sensitive credentials organized.

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

openma 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 6d 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.

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

openma

openma is an open-source platform for building, deploying, and managing AI agents. You define an agent (model + system prompt + tools), the platform handles sandboxed execution, credential management, and session state.

Setup

npx open-managed-agents            # or: npm i -g open-managed-agents
export OMA_BASE_URL=https://your-instance.workers.dev
export OMA_API_KEY=oma_xxxxxx      # generate at Console → API Keys

Run oma --help for all commands.

Core Workflow

oma agents create "my-agent" --model claude-sonnet-4-6
oma envs list                      # reuse existing, or:
oma envs create default
oma sessions create --agent <agent-id> --env <env-id>
oma sessions message <session-id> "Your task here"

What ships with it

4 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.
