Cortex

Project knowledge base for Claude Code.

Cortex analyzes your repository and writes .claude/docs/ — structured context files Claude Code reads before touching any file. It knows which parts of the codebase break most often, why certain decisions were made, and where the security risks are.

Not documentation you write. Knowledge extracted from your actual project history.

Install

curl -fsSL https://raw.githubusercontent.com/kovalenko-tech/cortex/main/install.sh | bash

Or with npx — no install required:

npx @kovalenko-tech/cortex-ai analyze

Requires Python 3.11+.

Related MCP server: ctx-gen-mcp

Quick start

cd your-project
cortex setup    # interactive wizard

Or directly:

cortex analyze
git add .claude/
git commit -m "add cortex context"

What Claude Code sees

Before writing a single line of code, Claude Code gets this for every file:

> ⚡ Fresh — analyzed 2026-03-22 UTC
> 🔴 HIGH RISK (score: 65/100) — 12 bug fixes · no test coverage

## Historical Insights
- [Bug Fix] 2024-03-15: Session fails on UTC+0 timezone
  Fix: Always use datetime.timezone.utc

## Decisions & Context
- ✅ Chose JWT over sessions for stateless auth — PR #234 @john
- 🚫 Don't call authenticate() before db.init() — PR #156 @maria

## Edit Checklist
- Run: pytest tests/test_auth.py -v
- Check: SESSION_TIMEOUT in config/settings.py

## Related Files
- tests/test_auth.py [co-change: 92%]

## Security Notes

Claude Code integration

Add to .claude/settings.json for automatic context injection:

{
  "mcpServers": {
    "cortex": {
      "command": "cortex",
      "args": ["mcp"]
    }
  }
}

GitHub PR knowledge

Mine implicit decisions from PR discussions:

export GITHUB_TOKEN=ghp_...
cortex mine-prs
cortex analyze

AI summaries

export ANTHROPIC_API_KEY=sk-ant-...
cortex analyze

Uses Claude Haiku to generate a 2–3 sentence technical overview per file. Optional — all other features work without an API key.
