What is xerj-knowledge?

A plugin that lets Claude search folders, notes, mail exports, PDFs, and spreadsheets with XERJ, a local document-indexing tool. It can cite the file and page, and the files remain on your machine.

Use it to answer questions about your own files, such as finding a contract clause, a past decision, or figures in a spreadsheet.

It reduces the effort of searching scattered personal documents while preserving the source needed to check an answer. It is for information stored locally, not general web research.

xerj-knowledge — Plugin for Claude Code by xerj-org/xerj

About the project

XERJ is a local search tool that automatically indexes folders so coding agents can retrieve relevant code, documents, logs, and PDFs without reading files one at a time. It is for developers and agents using code search, retrieval-augmented generation, security audits, or agent memory.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/xerj-org/xerj

Made for: Claude Code.

Security

Grade A, and why

xerj-knowledge 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 5d 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, 2 commands, 1 MCP server travel with it, and installing the plugin installs all of them — 112 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.
