swarm

swarm is a settings file for Claude Code from swarm-ai-research/swarm. Its token cost is not measured, scanned A, original, MIT.

A settings file for an AI coding project. It defines which tools the agent may use and when shell hooks run during a session.

In plain words
What is it for?
Use it to configure session-start, tool-use, subagent, and context-compaction hooks, along with allowed commands.
Why use it?
It makes the agent's permissions and automated checks explicit, helping control what it can do in the project.

Settings file for Claude Code

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else.

One of 6 entries in settings.json — they are configured in one file and arrive together.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code.

Grade A, and why

swarm 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 yesterday.

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 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.
