create-agent

create-agent is a skill for Claude Code, Codex from agno-agi/agentos-docker. It costs 114 tokens per session (3,110 once invoked), scanned B, original, Apache-2.0.

A guided workflow for adding a new software agent to AgentOS, including its source file, registration, description, suggested prompts, and basic test. An agent is a program configured to perform a particular job.

In plain words
What is it for?
Use it to create an agent from a concrete idea or guided discovery, register it in the platform, restart the service, and smoke-test the result.
Why use it?
It turns an idea into a registered, runnable agent while checking that its identifier is available. It also distinguishes source-code agents from components created in the visual builder.

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 B, and why

create-agent scanned grade B with 2 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 4d 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

`curl -sSf http://localhost:8000/health` returns 200. If not, ask the user to `docker compose up -d --build`.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

`curl -sSf http://localhost:8000/health` returns 200. If not, ask the user to `docker compose up -d --build`.

How it starts

The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create a New Agent

Coding-agent workflow: run as /create-agent or by describing the task.

The platform is on http://localhost:8000 (RUNTIME_ENV=dev); code edits hot-reload.

0. Preconditions

curl -sSf http://localhost:8000/health returns 200. If not, ask the user to docker compose up -d --build.

1. Find the agent worth building

Be self-driving: ask only what needs a human, decide the rest, say what you decided. Two exchanges is the target. Use the harness's structured choice control for choice-shaped questions, plain prompts for free-form ones.

This skill builds lane 1 — a source file in agents/, governed by git. Lane 2 is a component Platform Builder composes at runtime; it can't touch the repo, so anything needing a code change (a toolkit the registry lacks, custom Python, a dependency, growing app/registry.py) is yours.

Check the id is free first — both lanes share one id space and code silently wins, hiding a Studio-built component under your file:

curl -s http://localhost:8000/agents | jq -r '.[] | "\(.id)\t\(.is_component)"'

They named an agent ("build me a GitHub PR reviewer") → ask nothing. Design it, state it in one message, start:

Building PR Reviewer (pr-reviewer) — reads open PRs on a repo and summarizes what changed and what looks risky. Uses GithubTools; needs GITHUB_ACCESS_TOKEN, already in your .env. Building now — stop me if I've read it wrong.

They named a product (a URL, "an agent for Acme") → the product-agent pattern in Step 3. Ask nothing beyond the URL.

They want guidance → one question: "What's something you do every week that you'd rather hand off?" Dig once with a grounded follow-up (where do you look? what do you do with the result? what's the annoying part?), then propose one recommendation plus two alternates — name, one sentence, toolkit — grounded in the agno-docs MCP (.mcp.json). Skip the demo classics.

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.

create-agent is a skill published in the GitHub repository agno-agi/agentos-docker (6 stars, last pushed 3d ago), licensed Apache-2.0. It adds 114 tokens to every session and 3,110 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
