devlens

A codebase information tool for AI agents that provides a prepared graph of source-code parts and their relationships. It supports TypeScript, JavaScript, Python, Go, Rust, and Java projects.

In plain words
What is it for?
Use it to inspect how files, components, and other code elements relate in a supported repository. It is intended for agents working on an existing codebase.
Why use it?
It helps an agent understand connected code without searching through every file manually. The graph can include technical, business, and security summaries.

Security

Grade A, and why

devlens 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 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.
