Ysra is an autonomous software engineer. It works in an isolated copy of your
repository, runs your own checks against every change, has the result reviewed
independently, and delivers only what your policy allows.

- [**Quickstart**](getting-started/quickstart.md)

    Connect a repository and run your first session in minutes.

- [**How Ysra works**](concepts/how-ysra-works.md)

    Outcome, boundary, work, evidence, decision — and the loop inside.

- [**Walkthrough**](guides/walkthrough.md)

    One real session: a storefront and back office built from one brief.

- [**Boundaries & safety**](concepts/safety.md)

    What Ysra can touch, what needs your approval, and where the limits are.

## The same shape around every job

| Stage | What you do | What Ysra does |
|---|---|---|
| **Outcome** | Describe what should be true when it's done. | Turns it into explicit acceptance criteria. |
| **Boundary** | Set the budget, quality and what needs approval. | Holds to it for the whole job. |
| **Work** | Watch, steer or answer questions — or don't. | Plans, edits in isolation, runs your checks, repairs. |
| **Evidence** | Read the diff, the checks and the review. | Ties every result to the exact change, and names what's unproven. |
| **Decision** | Deliver, ask for changes, rewind or stop. | Publishes only what your policy or your click allows. |

## Three products, one workspace

<div class="cards" markdown>

- [**Developer**](developer/index.md)

    A repository-native engineer: sessions, the workroom, review, previews,
    delivery and multi-milestone projects.

- [**Knowledge**](knowledge/index.md)

    Answers from your files, Slack, Jira, Gmail and the web — with a citation
    for every claim.

- [**Workers**](workers/index.md)

    Scheduled and on-demand automations that ask before anything leaves your
    account.

- [**Integrations**](integrations/index.md)

    GitHub, Slack, Jira and Gmail — what each is used for, and what's planned.

- [**Workspace & account**](workspace/index.md)

    Files, wallet and usage, autonomy policy and settings.

- [**Mobile app**](mobile/index.md)

    Start, follow, approve and ship from your phone.

</div>

All of it shares one workspace, and the web portal and the iOS and Android apps
show the same live state.
