lintel CLAUDE.md

Repository guidance for Claude Code, covering the project layout, development commands, and rules for working in Lintel, an open-source platform that coordinates AI agents. It describes a Python workspace monorepo, meaning one repository containing many related packages.

In plain words
What is it for?
Understanding Lintel’s packages, dependencies, architecture, and common commands, while enforcing lint and type-check runs before commits.
Why use it?
It gives the coding agent the project context it needs and sets checks that must pass before code is committed. This helps prevent changes that fail linting or type checking.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

lintel CLAUDE.md 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 2d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Pre-Commit Rule

Before every commit, run make lint and make typecheck and fix any errors. Do not commit code that fails linting or type checking.

Project Overview

Lintel is an open-source AI collaboration infrastructure platform. It orchestrates multi-agent workflows triggered from Slack threads, using event sourcing and CQRS patterns. Built with Python 3.12+, FastAPI, LangGraph, and PostgreSQL.

Workspace Structure

This is a uv workspace monorepo with 45+ packages under packages/:

Core packages:

Package Name Dependencies Description
packages/contracts/ lintel-contracts (none) Pure domain contracts: types, commands, events, Protocol interfaces
packages/agents/ lintel-agents contracts AI agent runtime (roles: planner, coder, reviewer, pm, designer, summarizer)
packages/workflows/ lintel-workflows contracts, agents LangGraph workflow orchestration and graph nodes
packages/app/ lintel all below Thin composition root: lifespan wiring, middleware, router mounting

Reusable library packages (each independently installable):

Package Name Dependencies Description
packages/event-store/ lintel-event-store contracts Append-only event persistence (Postgres + in-memory)
packages/event-bus/ lintel-event-bus contracts In-memory pub/sub event bus
packages/projections/ lintel-projections contracts, event-bus Read-model projection engine and concrete projections
packages/persistence/ lintel-persistence contracts Generic CRUD/dict stores, vault
packages/sandbox/ lintel-sandbox contracts Docker-based code execution sandboxes
packages/pii/ lintel-pii contracts PII detection/anonymization (presidio)
packages/observability/ lintel-observability contracts OpenTelemetry tracing/metrics/logging
packages/models/ lintel-models contracts LLM provider routing (litellm)
packages/slack/ lintel-slack contracts Slack channel adapter
packages/repos/ lintel-repos contracts GitHub repository provider
packages/coordination/ lintel-coordination (asyncpg only) Database advisory locks
packages/infrastructure/ lintel-infrastructure (residual) MCP tool client only — will be dissolved

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.

lintel CLAUDE.md is an instructions file published in the GitHub repository bamdadd/lintel (10 stars, last pushed 4mo ago), licensed MIT. It adds 5,377 tokens to every session, about $0.0269 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
