A shared context service for coding agents. It maps source code, retrieves information from PDFs and other documents, stores shared agent memory, crawls the web when requested, and exposes Git history, blame, and symbol-level changes.

Use it when an agent needs repository structure, document or OCR search, shared memory, web research, or historical information about code changes.

It reduces the need to search separate sources manually and helps agents use code, documents, web material, memory, and history as project context.

basemind — Plugin for Claude Code and Gemini CLI by Goldziher

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/Goldziher/basemind

Made for: Claude Code, Gemini CLI.

Security

Grade A, and why

basemind 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.
