A tool for semantic analysis of Go code using gopls, the official Go language server. It understands code types and relationships rather than treating files as plain text.

Use it to find definitions and references, locate implementations, and inspect which functions call one another. It is useful when navigating or understanding a Go codebase.

It makes it easier to trace code accurately when names are repeated, types are involved, or a function’s callers are spread across a project.

Security

Grade A, and why

plugin 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.
