What is cortex-plugins?

A collection of tools for giving Claude Code persistent memory and a profile of how a project or user works. It includes memory retrieval with heat and decay, codebase intelligence, and cognitive profiling; some details depend on the available integrations.

Use it when you want ongoing project memory, intent-aware retrieval, codebase understanding, or cognitive profiles in Claude Code.

It helps an agent retain useful context across work and retrieve relevant information instead of treating every session as new.

Security

Grade A, and why

cortex-plugins 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.
