lex-align 2.2.2

Enterprise governance platform for AI-generated code: legal, security, and architectural alignment

lex-align

Docs · Getting started · Agent support · For agents

lex-align enforces your dependency policy before AI agents or developers can commit it. Every package gets checked against your approved registry, OSV CVE scores, and license rules — returning one of three deterministic verdicts so agents can act without ambiguity. Full docs at dlfelps.github.io/lex-align.

Why

Your AI coding agent adds packages to pyproject.toml faster than anyone can review them. By the time legal notices the AGPL dep, or security spots the critical CVE, it's already in main. You need the check to happen before the bytes are written, not after the PR is open.

---

How it works

A FastAPI server is the source of truth. The client is thin: a CLI plus hooks.

• Three gates per check: internal registry → OSV CVE → PyPI license.
• Three-verdict vocabulary: ALLOWED, PROVISIONALLY_ALLOWED, DENIED — small, deterministic, easy for an agent to branch on.
• Two enforcement points: a git pre-commit hook (universal backstop, fires for every agent and every human committing to a governed repo) and a Claude Code PreToolUse hook that intercepts pyproject.toml edits before the file is written.
• Use first, approve in parallel: an unknown package that passes CVE and license checks comes back PROVISIONALLY_ALLOWED. The agent uses it, calls request-approval, and keeps moving — formal review runs async.

Python and pyproject.toml only. Self-hosted via Docker Compose. Single-user mode is the default.

Quickstart

# Server (host you control)
pip install "lex-align[server]"
lex-align-server init && cd lexalign
lex-align-server registry compile registry.yml registry.json
docker compose up -d

# Client (per-project)
pip install lex-align
cd /path/to/your/project
lex-align-client init
lex-align-client check --package httpx

Agent support

Primary target is Claude Code — pre-commit hook, PreToolUse edit-time intercept, and an auto-written CLAUDE.md so every session knows how to use check and request-approval. Cursor, Aider, and anything else committing to a governed repo are backstopped by the pre-commit hook. Full matrix: agent support.

Project status

Phase	Status
1. Server core (registry, license, CVE, audit, evaluate)	✅ shipped
2. Thin client (init, check, request-approval, pre-commit, Claude hooks)	✅ shipped
3. Approval workflow UI + reporting endpoints	🟡 stubbed
4. Dashboards, PR-creation workflow, org-mode auth	⏸ deferred

request-approval persists each submission today, but the reviewer UI and the PR-creation workflow against the registry repo are not here yet. If you need a polished triage dashboard, this isn't that tool — yet.
