What is carrel-agent?

A plugin for carrel, a file-librarian tool that indexes files so agents can search, inspect, and package them. It includes a librarian agent, workflow guidance, an MCP server, and a hook that re-indexes files after an agent writes them.

Searching indexed files, inspecting and packaging file collections, running librarian workflows, and automatically refreshing the index after changes.

It keeps an agent's file index current and makes stored files easier to find and examine during work.

Security

Grade A, and why

carrel-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 installs

The manifest is a name and a version. 1 skill, 1 agent, 1 hook, 1 MCP server travel with it, and installing the plugin installs all of them — 127 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
