# Estelle documentation

> Estelle is an AI software factory. You give it work; it builds in its own cloud machines (Silos), reviews pull requests, tests your app, scans for security problems, runs CI and watches production. Every page below is also available as Markdown.

## Get started

- [Introduction](https://docs.fatelabs.ca/introduction.md): Learn how Estelle helps your team understand its code, delegate changes, review pull requests, test apps, and watch production.
- [Quickstart](https://docs.fatelabs.ca/quickstart.md): Create an account, choose solo or team setup, index your first repository, and ask Estelle a question with file and line citations.
- [Your first task](https://docs.fatelabs.ca/first-task.md): Give Agent mode a small code change, approve the proposal, follow the work in Orchestra, and review the resulting pull request.
- [Example repository](https://docs.fatelabs.ca/example-repo.md): Inspect a public example pull request and Twice run to learn how Estelle presents code review findings and running-app test results.
- [Install Estelle](https://docs.fatelabs.ca/install.md): Install the native plugin for Claude Code, Codex, Kimi Code, Grok Build or Cursor, or connect a tools-only MCP client.

## Build

- [Agent mode](https://docs.fatelabs.ca/agent-mode.md): Delegate coding and operational work to Estelle, review each proposed action, and follow the resulting plan and evidence.
- [Silos](https://docs.fatelabs.ca/silos.md): Start and supervise cloud computers for coding and desktop agents, inspect their work, and handle machine access and files safely.
- [Automations](https://docs.fatelabs.ca/automations.md): Run reports or reviewable changes on a schedule or in response to an event, with explicit connectors, permissions, limits, and run history.
- [Orchestra](https://docs.fatelabs.ca/orchestra.md): Review agent plans, follow builds and specialist runs through their evidence, and control work without confusing observed sessions with controlled runs.
- [Rooms](https://docs.fatelabs.ca/rooms.md): Coordinate local sessions, cloud agents, and people around one task with shared ownership, messages, handoffs, and human decisions.
- [Sessions](https://docs.fatelabs.ca/sessions.md): Inspect coding-agent conversations, plans, commands, changes, pull requests, reviews, and cloud desktops, and propose edits safely.

## Review and test

- [Prism](https://docs.fatelabs.ca/prism.md): Use Prism to review pull requests, investigate findings, understand coverage and scores, and understand advisory GitHub checks.
- [Twice](https://docs.fatelabs.ca/twice.md): Use Twice to approve browser-test plans, run user journeys, read reproduction evidence, export reports, and gate pull requests on confirmed defects.
- [Security](https://docs.fatelabs.ca/security.md): Use Estelle Security to scan a repository, control scope and fix options, evaluate findings and reproduction evidence, and record human triage decisions.
- [Estelle CI](https://docs.fatelabs.ca/ci.md): Use Estelle CI to configure workflows, run builds and tests in Silos, read step evidence and logs, and require meaningful GitHub checks.

## Run in production

- [Monitoring](https://docs.fatelabs.ca/monitoring.md): Use Monitoring to send telemetry, investigate issues and service health, configure alerts and uptime checks, and read production evidence from your agent.
- [On-call](https://docs.fatelabs.ca/awake.md): Use On-call to turn production signals into incidents, verify alert delivery, assess investigation evidence, request fix pull requests, and resolve incidents safely.

## Know your code

- [Atlas](https://docs.fatelabs.ca/atlas.md): Generate a cited guide to an indexed repository, ask questions inside it, and rebuild it when the code changes.
- [Intake](https://docs.fatelabs.ca/intake.md): Upload company documents, ask questions with line-level citations, and review the facts and entities Intake extracts.
- [Memory](https://docs.fatelabs.ca/memory.md): Resume past coding sessions, recall team decisions, and review or correct what Estelle remembers across supported agents.
- [Code graph](https://docs.fatelabs.ca/code-graph.md): Index a repository's files, symbols, and imports so you and your agents can locate code, assess change impact, and understand indexing refusals.

## Connect

- [GitHub](https://docs.fatelabs.ca/github.md): Connect the Estelle GitHub App, choose which repositories Estelle indexes, and use Prism, Estelle CI, and Twice on pull requests.
- [Slack, Linear, iMessage and SMS](https://docs.fatelabs.ca/channels.md): Ask Estelle from Slack, Linear, or iMessage, route automation summaries to Slack, and link Slack or SMS identities for automation setup.
- [MCP server](https://docs.fatelabs.ca/mcp.md): Connect an MCP client to Estelle for repository navigation, memory, monitoring, research, reviews, and agent jobs.
- [CLI](https://docs.fatelabs.ca/cli.md): Install the estelle CLI to index local repositories, configure MCP clients, capture sessions, and check code from a terminal.
- [API](https://docs.fatelabs.ca/api.md): Use Estelle's OpenAI-compatible chat completions endpoint from scripts and services, with bearer authentication, repository scoping, and explicit errors.

## Account

- [Plans and credits](https://docs.fatelabs.ca/plans.md): Choose a plan from the current catalogue, understand included usage and its limits, add usage, and manage your subscription.

- [Keys and models](https://docs.fatelabs.ca/keys-and-models.md): Create and revoke Estelle API keys, choose the model provider keys each product surface uses, and connect coding agents in Silos.
- [Autonomy](https://docs.fatelabs.ca/autonomy.md): Choose what Estelle may do without a review click, from read-only help to pull requests, branch writes and explicitly granted actions.
- [Settings](https://docs.fatelabs.ca/settings.md): Find every Settings section, personalize Estelle, choose notifications, manage automatic work, configure Intake, and export your data.
- [Export your data](https://docs.fatelabs.ca/data-export.md): Download everything Estelle holds for your workspace as JSONL files, including training files for a local or custom model.
- [Troubleshooting](https://docs.fatelabs.ca/troubleshooting.md): Fix sign-in, MCP, session, repository indexing, usage, provider-key, team-invite, review and notification problems.
