crew-agent

A command for creating, viewing, and removing custom project-specific coding agents.

In plain words
What is it for?
Use `/crew agent create` to add an agent, `/crew agent list` to view built-in and custom agents, or `/crew agent remove` to delete a custom agent.
Why use it?
It lets a project add specialists tailored to its own needs and keep their definitions with the project.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 20 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 111 The whole file, excluding the scripts and references it only reads on demand.

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

crew-agent 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 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.

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.

What it actually says

Invoke the codecrew:agent-manager skill with the user's subcommand.

Parse the subcommand:

  • /crew agent create "name" --model sonnet --description "desc" → Create a new custom agent
  • /crew agent list → List all agents (built-in + custom)
  • /crew agent remove "name" → Remove a custom agent

Pass the full subcommand and arguments to the skill.

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.
