Agentarmor
stylusnexus · Agent
Agent Armor is an open-source framework for detecting AI Agent Traps: content injection, embedded jailbreaks, RAG poisoning and data exfiltration. It scans what an agent ingests, such as web pages, retrieved chunks, tool outputs and database results, and what the agent returns to the user. A command line scans agent instruction files, and the examples show gating tool calls, filtering poisoned RAG chunks and Express middleware.

Why it's useful
An agent cannot tell data from directives in the content it reads, so this checks that content before it can steer the agent.
What you could do with it
- Add a pre-commit hook that scans your agent instruction files and fails on anything rated high.
- Filter poisoned chunks out of a retrieval pipeline before they reach the model's context.
- Gate every tool call in a custom agent loop, scan each result and the reply, and log every decision.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.2.23, the file with digest sha512-HCv5OLEnxObV1M5cZsKAQPNcOA9WnzhEv+i5xHOU3qCngpoz5ppbC2VlMLWkoe5GvSwAaWLTV6elIcOEM7bn+Q==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
