These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 112 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

npm install -g @openma/cli
oma auth login --base-url https://app.openma.ai

For self-hosted instances, replace the login URL with the user's server origin. Confirm the instance and workspace before creating resources. Let the user complete browser authentication. For automation, accept OMA_BASE_URL and OMA_API_KEY from an existing secret manager or protected environment; do not ask for secrets in chat or print them in logs.

Run oma --help and oma api to check the installed CLI's commands and API shape. The CLI connects to an existing server; installing it does not deploy OpenMA.

Core Workflow

oma models list
oma envs list
oma agents list

Use an existing Model Card's model_id, not its database record ID. Choose a ready environment with the needed runtime capabilities. Create missing resources only as required for the user's task; replace the placeholders below with the returned IDs:

oma agents create "my-agent" --model <model-id> --system "Help with the requested task."
oma sessions create --agent <agent-id> --env <environment-id>
oma sessions chat <session-id> "Your task here"

chat sends a turn and streams its reply. message sends without waiting; tail follows events. A delivered message is not proof that the task succeeded. Check the resulting session status, events and outputs.

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.
