codeweaver

A code-search server that helps an AI agent find relevant parts of a codebase by meaning as well as matching words. It understands code structure and can split code into useful search sections across more than 166 languages.

In plain words
What is it for?
Use it to locate related functions, classes, and files; explore an unfamiliar codebase; and provide more relevant code context to an AI agent.
Why use it?
It reduces the time an AI agent spends searching through unrelated files or missing code that uses different wording. An optional Voyage AI key provides the embedding service used for meaning-based search.

Grade A, and why

codeweaver 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.
