cortex

cortex is a skill for Claude Code, Codex, Cursor from synpulse8-opensource/pulse8-ai-cortex-knowledge-vault. It costs 44 tokens per session (622 once invoked), scanned A, original, Apache-2.0.

A routing guide for PULSE8.ai Cortex, a knowledge-vault system with searchable documents, a graph, REST and MCP interfaces, and Docker deployment. An MCP interface lets tools such as Cursor or Claude Desktop connect to it.

In plain words
What is it for?
Use it when working in the Cortex repository on vault files, document ingestion, search, graph or compiler behavior, MCP connections, REST APIs, authentication, feedback, or Docker and EC2 deployment.
Why use it?
It directs work to the correct instructions for the vault, search, authentication, APIs, MCP setup, or deployment instead of editing the wrong part of the system.

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 scanned grade A with 1 finding 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 4d 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.

Audience

  • Operators: cortex-deploy, cortex-vault, cortex-mcp, cortex-compiler (run/ingest/debug).
  • Contributors: cortex-contributing plus the domain skill you are changing.

Rules

  • Do not implement across modules without reading the relevant sub-skill.
  • MCP handlers live in cortex/mcp/tools.py; REST in cortex/api/routes.py — keep parity when adding features.
  • Configuration: cortex/config.py (CORTEX_* env prefix).

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.
