What is cortex-engine CLAUDE.md?

Project instructions for Cortex Engine, a portable cognitive engine for AI agents distributed as an npm package. They describe its commands, source layout, release rules, and supported services.

Use them when working on the TypeScript source, cognitive processing, memory, providers, plugins, REST or MCP servers, and release-related files.

They give an agent the project context needed to build, test, serve, and change the code without breaking its workflow conventions.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00924	$0.00924
Opus 5.5	$0.00370	$0.00370
Sonnet 5.5	$0.00185	$0.00185
Haiku 4.5	$0.00092	$0.00092

Security

Grade A, and why

cortex-engine 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 1mo 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.

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

cortex-engine

Portable cognitive engine for AI agents. Published as @fozikio/cortex-engine on npm.

Workflow tier: Production

Conventional commits with scopes and explanatory bodies, PR-required (no direct pushes to master), the local-ci status (npm run ci:local -- <branch> on the PR's final head) as the merge gate required by the master ruleset, Keep-a-Changelog CHANGELOG.md with semver tags. New clones: run git config core.hooksPath .githooks once to activate the commit-msg lint hook.

Commands

npm run build        # tsc → dist/
npm run dev          # tsc --watch
npm run test         # vitest (requires --experimental-vm-modules)
npm run test:watch   # vitest watch mode
npm run serve        # Start MCP server (node dist/bin/serve.js)
npm run docs:tools   # Regenerate docs/tools-reference.md from dist/ (build first)
npm run ci:local -- <ref>  # Merge gate: CI checks in a clean worktree, posts `local-ci` status

Changes

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.
