The navigation star for coding agents

A north star for your coding agents.

Rigel charts every service, API and event across your repos — tens to hundreds of them — briefs any coding agent over MCP, and scores every pull request, so a change in one repo doesn't break another.

Built for microservice estates

It doesn't have to break downstream.

Microservice architectures span tens to hundreds of repositories — no single coding session can hold that whole system in context, and each repo's agent sees only its own repo. An agent renames a field in a shared package; the reviewer sees one repo, not the two services in other repos that read it. Rigel holds the whole chart and briefs the agent first.

Blind spot · today
The agent and reviewer only see orders-api.

Nobody sees who consumes @acme/orders-client. The rename ships.

fulfillment ✗ TypeError: customerId is undefined
billing ✗ invoices failing · 500s
With Rigel · ask first
The agent calls find_consumers over MCP.

Two services in two other repos depend on the package. The agent keeps customerId @deprecated and names both in the PR.

One source of truth

Every agent builds to the same chart.

Rigel centralizes what a distributed system knows about itself — service topology, API and event contracts, and the patterns your teams actually follow — and serves it to any coding agent over MCP. An agent working on one service builds consistently with the other hundred, instead of guessing from a single repo.

Architecture & patterns

Build in-house style.

Agents inherit the design and architecture patterns already in your code, so new work matches what's there — not a generic default.

Contracts & workflows

Respect the seams.

APIs, events and queues across repos are mapped, so a change honors the contracts other services and workflows depend on.

Infrastructure style

Fit the platform.

How your services are configured, built and deployed travels with the chart, so agents follow your conventions by default.

How it works

1
SeeOne living map

Rigel reads all your repos and draws one branch-aware map of how your services connect — refreshed on every merge.

2
BriefAgents ask first

Before an AI coding agent changes code, it asks Rigel what else depends on it, over MCP.

3
ScoreImpact on every PR

In repos where you turn Impact on, every pull request gets an explainable risk score and blast radius.

4
GovernGated auto-merge

The PRs Rigel's own agents open are tested, reviewed and checked against your rules, then merged inside your branch protection — or held for a person, with a reason.

The platform

Three products, one chart.

Rigel Map

Chart your estate.

A live, branch-aware map of services, APIs and events, built from code and queryable by any agent over MCP.

Rigel Impact

See the blast radius.

Every pull request scored for cross-service risk before it merges — the consumers a change will break, named.

Rigel Autopilot

Govern every merge.

The PRs Rigel's own agents open merge only when your CI, review and policy gates pass. Everything else waits.

Fit & proof

We're early. Here's what's real.

Rigel is in Beta with design partners: engineering orgs running 20+ services across many repos. These are mechanisms you can check, not benchmarks we're asking you to take on faith.
