CLAUDE.md

cortex CLAUDE.md is an instructions file for Claude Code from moguls753/cortex. It costs 2,227 tokens per session, scanned A, original, AGPL-3.0.

A project instruction file for the moguls753/cortex codebase. It explains the project, records important technical decisions, describes the technology used, and says never to commit or push changes.

In plain words
What is it for?
Orienting work in the cortex project and enforcing its development and repository-handling rules.
Why use it?
It gives the coding agent project-specific context and prevents changes from being committed or sent to a remote repository.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is moguls753/cortex's own configuration. It tells Claude Code how to work on cortex itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cortex configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cortex CLAUDE.md 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 2mo 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.
