Introduction

CortexFlow Architecture Overview

CortexFlow unites non-deterministic large language model reasoning with deterministic Abstract Syntax Tree (AST) compilation. Traditional code assistants produce hallucinations because they rely purely on next-token prediction without compiler feedback. CortexFlow introduces a dual-layer verification loop:

Repository AST ➔ MCP Server ➔ Claude Sonnet 5.5 (Hybrid Reasoning) ➔ TSC Formal Verifier ➔ Git PR

CLI Quickstart

Initialize CortexFlow inside any TypeScript, JavaScript, or Next.js repository using our global CLI:

# Install and initialize CortexFlow in your project root

npm install -g @cortexflow/cli

cortexflow init --api-key=sk-ant-api03-***

Claude 5.5 Generation Model Matrix

CortexFlow dynamically selects the optimal model from Anthropic's flagship 5.5 lineup based on task complexity:

Model Name	Model Identifier	Release Date	Role in CortexFlow
Claude Sonnet 5.5	claude-sonnet-5-5-20260928	September 28, 2026	Flagship AST Patch Synthesis (30% faster)
Claude Opus 5.5	claude-opus-5-5-20260922	September 22, 2026	Cross-Monorepo Dependency Architecture
Claude Fable 5.1	claude-fable-5-1-20260901	September 1, 2026	Long-Horizon Strategic Task Planning
Claude Haiku 5.5	claude-haiku-5-5-20261007	October 7, 2026	Sub-15ms AST Node Filtering & Lint Triage

Model Context Protocol (MCP) Server

CortexFlow implements Anthropic's Model Context Protocol (MCP), allowing Claude Desktop, Claude Code, and autonomous agents to query AST semantics directly:

{
  "mcpServers": {
    "cortexflow": {
      "command": "cortexflow-mcp",
      "args": ["--port", "4820", "--repo", "./"],
      "env": {
        "ANTHROPIC_API_KEY": "sk-ant-api03-***"
      }
    }
  }
}

Automated GitHub Actions CI/CD

Add automated AST refactoring and reasoning PRs on every Pull Request or cron audit:

name: CortexFlow Claude 5.5 Audit

    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
