create-agent

A guided workflow that adds a new software agent to the AgentOS platform and connects it to the application registry.

In plain words
What is it for?
Turn an agent idea into a registered agent, generate its source and manifest entry, restart the local platform, and run a smoke test.
Why use it?
It removes the repetitive work of creating the agent file, registration details, prompts, restart steps, and basic testing.

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 2d 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`.

Makes network callslowCapability

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-render (2 stars, last pushed 2d 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). It is 100% identical to create-agent, differing in 0 lines, and is treated as a copy.
