create-agent

create-agent is a skill for Claude Code, Codex from Fandhe-AI/agent-cli-skills. It costs 67 tokens per session (2,332 once invoked), scanned C, original, no licence file.

A guided setup tool for scaffolding sub-agent definitions, including their category, files, model, allowed tools, and quality checks.

In plain words
What is it for?
Use it when creating or adding a sub-agent, including requests such as “create-agent.”
Why use it?
It turns the steps for adding a new sub-agent into one consistent process and limits access to only the tools it needs.

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 C, and why

create-agent scanned grade C with 1 finding 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

What ships with it

1 file 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.
