# Lobby Docs

> Work with AI agents and teammates on shared GitHub repositories.

# Overview
Source: https://docs.joinlobby.dev/

Lobby brings your repository, agent conversations, and code review into one
shared workspace. Connect GitHub, give an agent a task, inspect its work, and
publish the changes when they are ready.

[Open Lobby](https://joinlobby.dev/app) or follow the
[getting started guide](/quickstart).

## From task to reviewed change

1. **Connect a repository.** Install the Lobby GitHub App for the repositories you want to work on.
2. **Start a conversation.** Describe the outcome and choose an available agent and model.
3. **Work together.** Continue the conversation, inspect files, and coordinate with teammates.
4. **Review and publish.** Read the diff, run checks, then commit and push to GitHub.

## Explore Cloud Agents

- [Conversations and workspaces](/conversations): give agents context and continue shared work.
- [Capabilities](/capabilities): understand what agents can do and where authority stops.
- [Best practices](/best-practices): structure tasks, review evidence, and coordinate safely.
- [Projects and tasks](/projects-tasks): organize durable work across conversations and teammates.
- [Development environments](/development-environments): configure write-only values and renewable AWS access.
- [Review and publish changes](/source-control): select the right worktree, inspect diffs, and publish.
- [Demo videos and CLI](/demos): record a changed interaction and share a private watch link.
- [Teams and enterprise](/teams-enterprise): roll out a team and evaluate administration and security boundaries.
- [For agents](/agents): read the docs as Markdown and attach evidence to completed work.

# For agents
Source: https://docs.joinlobby.dev/agents

## Read without browser automation

- [llms.txt](/llms.txt): documentation index.
- [llms-full.txt](/llms-full.txt): complete Markdown reference.
- [llm.txt](/llm.txt): alias for the index.
- Append `.md` to a guide route, such as [quickstart.md](/quickstart.md), for its raw Markdown.

Start with [Conversations and workspaces](/conversations) and
[Review and publish changes](/source-control). Read the repository's own
instructions before editing; they define its local workflow and checks.

## Return reviewable results

Inspect the current branch and working tree, understand the affected code and
callers, and preserve unrelated edits. Make the smallest complete change and
run checks that exercise the behavior. Report what passed and what remains
unverified, along with where the changes live and whether they are published.

For visible UI changes, record the interaction with the real updated app.
Inspect the recording before uploading through [Lobby's demo CLI](/demos),
then return the permanent watch URL. Label mock data honestly. A local file
path or an expiring storage URL is not a hosted demo link.

# Overview
Source: https://docs.joinlobby.dev/api

Lobby's Cloud Agents API is available through the `lobby` CLI and its
local Model Context Protocol server. Both use the same account, repository, and
conversation authorization as the product.

## Quickstart

The CLI is currently installed from a Lobby checkout. With Node 24.18 or newer
in the Node 24 line and npm 11:

```sh
npm ci
npm run build --workspace @coding/cli
npm link --workspace @coding/cli
lobby login --email you@company.com
lobby conversations list
```

Enter the emailed code when prompted. The final command returns the conversations
the signed-in person can currently access, including the IDs used to scope later
reads:

```json
{
  "conversations": [
    {
      "id": "00000000-0000-4000-8000-000000000001",
      "title": "Document the API",
      "visibility": "shared",
      "repositoryId": 123456789,
      "state": "completed",
      "createdAt": "2026-09-14T08:00:00.000Z"
    }
  ]
}
```

Continue with [Authentication](/api/authentication),
[List Conversations](/api/list-conversations), [Get Project](/api/get-project),
[Upload A Demo](/api/upload-demo), or [MCP Setup](/api/mcp).

## Supported surfaces

| Surface | Use it for | Availability |
| --- | --- | --- |
| CLI | Conversation discovery, authorized project reads, agent coordination, approvals, and demo videos | Source install |
| Local MCP | Project/task tools and demo uploads in MCP-capable clients | Source install, stdio |
| In-agent API | Project writes, file claims, scoped approvals, and uploads from an active Lobby conversation | Supplied to eligible Lobby agents |

## Current boundary

Lobby does not yet offer customer API keys, service accounts, a published CLI
package, or a stable public REST/OpenAPI contract. Browser-session and short-lived
agent-capability endpoints are internal transport for the supported CLI and MCP
interfaces; do not call or depend on them directly.

# Acquire A Claim
Source: https://docs.joinlobby.dev/api/acquire-claim

<Columns cols={2}>
  <Column>

<Badge>CLI</Badge> `lobby claims acquire PATH`

## Parameters

| Name | Type | Description |
| --- | --- | --- |
| `PATH` | string | Exact repository-relative path; no `.git`, `..`, or absolute path. |
| `task` | string | Purpose from 1 to 200 characters. |
| `ttl` | integer | 30–1,800 seconds; default 300. |

Acquire again to renew and retain the newest lease ID. A conflicting live claim
returns an error; inspect claims before retrying.

  </Column>
  <Column>

### Request

```sh
lobby claims acquire src/api.ts --task 'Update API' --ttl 300
```

### Response

```json
{"path":"src/api.ts","leaseId":"LEASE_ID","task":"Update API","expiresAt":1789373100000,"advisory":true}
```

  </Column>
</Columns>

# Authentication
Source: https://docs.joinlobby.dev/api/authentication

## Local CLI and MCP

Run an interactive email-code login once for each Lobby origin:

```sh
lobby login --email you@company.com
```

The CLI verifies the identity with Lobby and saves an owner-readable session in
the local user's configuration directory. Browser sign-in is separate. Never copy
the saved session into a repository, command argument, MCP configuration, prompt,
or another user's account.

Run `lobby logout` to remove the local session. Sign in again after the session
expires. For a non-production deployment, pass the same `--site HTTPS_ORIGIN` to
login and later commands; login also accepts `--auth-url HTTPS_ORIGIN` when that
deployment uses another Auth origin.

Account membership and each person's GitHub repository permission are checked by
the server. A conversation ID selects scope; it does not grant access. Discover
authorized IDs with:

```sh
lobby conversations list
```

## Inside a Lobby agent

Lobby supplies short-lived, conversation-scoped authority to eligible agents.
Commands inherit the account, repository, conversation, run, and actor; omit
`--site`, `--conversation`, and `--repository` when the command says scope is
inherited. The agent cannot turn that capability into broader or durable access.

## API keys

Lobby does not currently issue customer API keys or service-account credentials.
The product's browser cookies and internal bearer capabilities are not substitutes
for an API key and are not a stable public integration contract.

---

# CLI reference
Source: https://docs.joinlobby.dev/api/cli

Run `lobby --help` for the reference shipped with your checkout.

## Account commands

| Command | Result |
| --- | --- |
| `lobby login --email EMAIL` | Start email-code sign-in and save a local CLI session. |
| `lobby logout` | Remove the local session. |
| `lobby conversations list` | List conversations currently visible to the signed-in account and GitHub identity. |

## Read conversation and project state

Outside Lobby, add `--conversation ID` to select an authorized repository and
conversation scope:

```sh
lobby agents list --conversation 00000000-0000-4000-8000-000000000001
lobby chats read CHAT_ID --conversation 00000000-0000-4000-8000-000000000001
lobby project get --conversation 00000000-0000-4000-8000-000000000001
lobby tasks list --conversation 00000000-0000-4000-8000-000000000001
lobby comments list --task-id TASK_ID --conversation 00000000-0000-4000-8000-000000000001
```

Paged commands return `nextCursor`. Pass it back with `--cursor` and keep the same
filters until it is absent or null. Chat reads return bounded text and omit tool
payloads, attachments, and private runtime traces.

Project and task writes, file claims, and access approvals require an active
writable Lobby agent. Their account, repository, conversation, run, and author
are inherited rather than selected by command-line flags. Run `lobby --help`
inside that session for the available write commands and required revisions.

## Demo videos

```sh
lobby demos upload /absolute/path/demo.webm --repository 123456789
lobby demos open https://joinlobby.dev/demos/DEMO_ID
lobby demos delete https://joinlobby.dev/demos/DEMO_ID
```

Uploads accept MP4 or WebM up to 20 MiB and print a private permanent viewer URL.
Add `--chapters FILE.json` for an ordered array of `{ "time", "title" }` entries.
Upload needs repository write access; playback needs account membership and
repository read access. Delete only when removal is intended.

# Delete A Demo
Source: https://docs.joinlobby.dev/api/delete-demo

<Columns cols={2}>
  <Column>

<Badge>CLI</Badge> `lobby demos delete VIEWER_URL`

The uploader or a team owner/admin needs repository write access. Successful
removal returns no payload. Storage is versioned, so recovery remains an operator
action; do not delete cited evidence casually.

  </Column>
  <Column>

### Request

```sh
lobby demos delete \
  https://joinlobby.dev/demos/DEMO_ID
```

### Response

```text
Demo removed.
```

  </Column>
</Columns>

# Get Project
Source: https://docs.joinlobby.dev/api/get-project

<Columns cols={2}>
  <Column>

<Badge>CLI + MCP</Badge> `get_project`

Read this before resuming project work. The project and repository are selected by
the conversation, never by caller-supplied identity fields.

## Parameters

The MCP tool accepts an empty object. Outside Lobby, the CLI requires an authorized
`--conversation UUID`.

Use returned revisions for later writes. On conflict, read again and reconcile.

  </Column>
  <Column>

### Request

```sh
lobby project get \
  --conversation 00000000-0000-4000-8000-000000000001
```

### Response

```json
{"project":{"id":"PROJECT_ID","brief":"# Project brief","revision":4},"conversationTask":{"taskId":"TASK_ID","revision":1}}
```

  </Column>
</Columns>

# Get A Task
Source: https://docs.joinlobby.dev/api/get-task

<Columns cols={2}>
  <Column>

<Badge>CLI + MCP</Badge> `get_task`

## Parameters

| Name | Type | Description |
| --- | --- | --- |
| `id` | UUID | Task returned by List Tasks or Save A Task. |
| `conversation` | UUID | Authorized scope outside Lobby. |

Comments are separate; use List Comments. The returned revision is required for
safe updates.

  </Column>
  <Column>

### Request

```sh
lobby tasks get --id TASK_ID --conversation CONVERSATION_ID
```

### Response

```json

# Guard A File
Source: https://docs.joinlobby.dev/api/guard-file

<Columns cols={2}>
  <Column>

<Badge>CLI</Badge> `lobby claims guard PATH`

Normally invoked by `coding-file`. The operation retains an owned claim or creates
a temporary five-minute claim. A conflicting live claim stops the write.

Claims are advisory for arbitrary shell programs; use the guarded writer when
enforcement is required.

  </Column>
  <Column>

### Request

```sh
lobby claims guard src/api.ts
```

### Response

```json
{"path":"src/api.ts","leaseId":"LEASE_ID","expiresAt":1789373100000,"advisory":true,"release":true}
```

  <Column>

<Badge>MCP</Badge> `link_task`

## Parameters

| Name | Type | Description |
| --- | --- | --- |
| `taskId` | UUID | Task in the inherited project. |
| `revision` | integer | `conversationTask.revision`, or 0 with no link. |

Conversation and project identity are inherited. Linking does not change task
status.

  </Column>
  <Column>

### Request

```sh
lobby tasks link --task-id TASK_ID --revision 0
```

### Response

```json
{"conversationTask":{"taskId":"TASK_ID","revision":1}}

# List Task Statuses
Source: https://docs.joinlobby.dev/api/list-task-statuses

<Columns cols={2}>
  <Column>

<Badge>CLI + MCP</Badge> `list_task_statuses`

The tool takes no fields. Outside Lobby, the CLI requires an authorized
conversation scope. Task status is separate from agent execution state.

  </Column>
  <Column>

### Request

```sh
lobby tasks statuses --conversation CONVERSATION_ID
```

### Response

```json
{"statuses":["todo","in_progress","in_review","done"]}

  <Column>

<Badge>CLI + MCP</Badge> `list_tasks`

## Parameters

| Name | Type | Description |
| --- | --- | --- |
| `query` | string | Case-insensitive title or description text. |
| `state` | enum | `todo`, `in_progress`, `in_review`, or `done`. |
| `parentId` | UUID | Direct subtasks of one task. |
| `limit` | integer | Page size from 1 to 20; default 5. |
| `cursor` | string | Opaque cursor from the previous page. |

An empty filtered page can still have a cursor; follow it until null.

  </Column>
  <Column>

### Request

```sh
lobby tasks list --conversation CONVERSATION_ID --query docs --limit 5
```

### Response

```json
{"tasks":[{"id":"TASK_ID","title":"Document Cloud Agents","state":"in_progress","revision":3}],"nextCursor":null}
```

  </Column>
</Columns>

# MCP Setup
Source: https://docs.joinlobby.dev/api/mcp

After [installing and signing in](/api), configure a local stdio server:

```json
{
  "mcpServers": {
    "coding": {
      "command": "lobby",
      "args": [
        "mcp",
        "--conversation",
        "00000000-0000-4000-8000-000000000001",
        "--repository",
        "123456789"
      ]
    }
  }
}
```

Use the executable's absolute path if the client cannot find `lobby`. The MCP
process must run as the same local user that completed `lobby login`.

With `--conversation`, the server exposes read-only project, task, and comment
tools. `--repository` enables `upload_demo`. Inside an eligible Lobby agent,
scope is inherited and write tools are also available.

| Tool | Purpose |
| --- | --- |
| `get_project` | Read the project brief and current task link. |
| `list_tasks`, `get_task`, `list_comments`, `list_task_statuses` | Read paged project work. |
| `save_project`, `save_task`, `save_comment`, `link_task` | Mutate project work inside an authorized writable agent. |
| `upload_demo` | Upload an existing reviewed MP4/WebM and return a private viewer URL. |

Tool discovery returns the current schemas, field limits, and read/write hints;
use those definitions instead of copying internal HTTP request bodies. A hosted
MCP server cannot read local files or reuse the local CLI session, so Lobby does
not currently advertise one.

# Best Practices
Source: https://docs.joinlobby.dev/best-practices

## Describe the outcome

Ask for observable behavior, not just an implementation technique. Include the
relevant feature, constraints, and the checks that define completion. Attach files
only when they are needed for the task.

For unfamiliar repositories, begin with orientation: ask the agent for entry points,
key modules, and project instructions before requesting a broad change.

## Keep related work together

Continue corrections in the same conversation so the agent retains context. Use a
project and durable tasks when work spans conversations or people. Split overlapping
or incompatible changes into separate worktrees, and claim exact shared files before
editing them concurrently.

## Review evidence, not confidence

An agent response is not proof that a change works. Review the diff and ask for the
project's real tests, type checks, lint, or build. For visible UI changes, require a
recording of the actual interaction and verify the hosted playback link.

## Publish deliberately

Confirm the selected repository, worktree, and branch before committing. Commit only
the intended files. Treat commit, push, and pull-request creation as separate steps,
and verify the remote result after publication.

Use the narrowest credential and network access that completes the task. Never paste
secrets into prompts, repository files, terminal history, or demo recordings.

# Capabilities
Source: https://docs.joinlobby.dev/capabilities

## Work in the repository

Cloud agents can inspect files, search the codebase, edit source, run the project's
installed tools, and use Git inside their assigned workspace. They receive the
repository instructions and conversation context needed for the task.

Repository access comes from the signed-in person's GitHub installation. Read-only
access stays read-only. The agent cannot select another account or repository by
changing a request body or command flag.

## Use the development workspace

An agent can run shell commands and localhost services in its cloud workspace.
Repository-defined setup and services live in `.coding/workspace.json`. Managed
service credentials are released only to the named service process, not to the
agent terminal or every process in the workspace.

## Coordinate project work

Agents in a shared project can read the durable brief, take tasks, append progress
comments, inspect peer activity, and claim exact files before editing. Task and file
authority is revision-checked and scoped to the active conversation and run.

## Review and publish

Agents can run checks and prepare Git commits. Publishing changes, opening pull
requests, uploading demo evidence, and sensitive operations remain subject to the
repository permission and approval boundary shown by Lobby.

Available models and adapters depend on the deployment and configured model access.
Use the options shown in the conversation composer rather than assuming a provider
or model is available.

---

# Conversations and workspaces
Source: https://docs.joinlobby.dev/conversations

## Keep the task and its context together

A conversation holds your instructions, agent responses, and tool activity.
Describe the desired behavior, the relevant files or constraints, and what
should count as a successful check. Send corrections in the same conversation
so the agent can use the existing context.

Available agents and models appear in Lobby's selector. Availability depends
on the deployment and your configured access; use the options shown there.

## Understand what is shared

Members of the same Lobby account can open and continue shared conversations.
Repository access still controls which GitHub repositories you can use.

Conversations can share a live branch or use different Git worktrees. A
conversation is not automatically an isolated copy of every file. Check its
workspace and branch before assigning overlapping edits. Use separate worktrees
when tasks need incompatible changes, and bring reviewed work back together.

## Continue later

Opening conversation history does not itself start a new cloud workspace.
Sending another message resumes retained compute or restores the workspace
when a suitable checkpoint is available.

If Lobby reports that a workspace cannot be recovered, preserve the error
and resolve it before assuming your files are available. Commit and push
reviewed work to GitHub rather than relying on a live workspace as your only copy.

## Ask for evidence

An agent finishing its response does not prove the task passed. Ask for the
checks it ran, their results, and any remaining limitations. Review diffs for
code changes and [demo videos](/demos) for visible interactions.

---

# Demo Evidence
Source: https://docs.joinlobby.dev/demos

Record the actual UI interaction and pause on its result. Label sample data or
mocked services, and keep credentials and unrelated private content out of the
recording. Lobby accepts WebM and MP4; uploads must fit within 20 MiB and two
minutes. The CLI uploads existing recordings; it does not record your screen.

## Install the CLI from source

The CLI is currently private and installed from a Lobby checkout, rather than
a public npm release. With Node 24.18 or newer in the Node 24 line and npm 11:

```sh
npm ci
npm run build --workspace @coding/cli
npm link --workspace @coding/cli
lobby login --email you@company.com
```

Enter the emailed code in the terminal. The CLI saves its own private session;
browser sign-in does not sign the CLI in. Use `lobby logout` to remove that
local session, and run login again when it expires.

## Upload and open

Use the numeric GitHub repository ID:

```sh
lobby demos upload /absolute/path/demo.webm --repository 123456789
```

The command prints a permanent **Demo:** watch URL. Open that returned URL with
`lobby demos open URL`, inspect playback, and share it with your team. Use
`lobby demos open` to browse the library.

For several steps, save an ordered `chapters.json` with times in seconds:

```json
[
  {"time": 0, "title": "Open the project list"},
  {"time": 5, "title": "Create a project"}
]
```

```sh
lobby demos upload /absolute/path/demo.webm --repository 123456789 --chapters chapters.json
```

## Access and retention

The uploader needs Lobby organization membership and repository write access.
Viewers must sign in with membership in the same organization and repository
read access. A watch URL does not grant access by itself. A browser organization
switch does not change the CLI session's organization.

Ordinary uploads are retained evidence. Use `--retention disposable` only for
throwaway tests; those recordings expire and must not be used as commit evidence.
Delete an authorized recording with `lobby demos delete URL` when its removal
is intended. Deletion makes existing watch links unavailable.

## Inside a Lobby agent

The running conversation supplies identity and repository authority:

```sh
lobby demos upload /absolute/path/demo.webm --chapters chapters.json
```

Omit `--repository` and do not copy a personal CLI session into the workspace.
See [For agents](/agents) for the documentation entry points.

# Builds And Services
Source: https://docs.joinlobby.dev/development-environments

Development environments let an application run with the values it needs without
putting credentials in Git, `.env`, setup commands, or an agent's terminal. Lobby
stores values above the workspace and releases them only when a signed-in user
starts the declared service.

## Declare the service

Add version 2 of `.coding/workspace.json` to the repository. A service accepts one
credential binding by name:

```json
{
  "version": 2,
  "cwd": ".",
  "setup": [],
  "services": {
    "app": {
      "command": "npm",
      "args": ["run", "dev"],
      "port": 3000,
      "readinessPath": "/",
      "credentials": ["app-development"]
    }
  }
}
```

The binding is repository-scoped. Setup commands, other services, agents, and
interactive terminals do not inherit it.

## Environment secrets

Open **Settings → Development environments → Environment secrets**. Select the
repository, enter a binding name and one or more variables, then choose
**Save without reveal**.

Values are encrypted in transit and at rest. After saving, Lobby returns only
the variable names and binding metadata; there is no reveal action. Use
**Replace values** to submit a complete new set. Do not use this store for public
configuration that can safely live in the repository.

The selected service receives the values as ordinary environment variables.
Lobby redacts exact issued values from captured service output, but application
code can still transform or transmit them. Give the service only the network and
upstream permissions it needs.

## AWS cloud roles

Use an AWS role instead of uploading access keys or a developer's AWS SSO cache.
Open **Settings → Development environments → AWS cloud roles**, select the
repository, enter the role ARN and AWS region, then create the binding.

Lobby shows a trust statement containing its exact AWS principal and a unique
external ID. Add that statement to the customer role, choose **Verify**, then
**Enable**. Keep the role policy narrow—for example, allow only the development
Secrets Manager and KMS resources needed by this repository.

When the service starts, Lobby assumes the role for one hour and exposes AWS's
standard container credential provider variables:

```text
AWS_CONTAINER_CREDENTIALS_FULL_URI
AWS_CONTAINER_AUTHORIZATION_TOKEN_FILE
AWS_REGION
AWS_DEFAULT_REGION
```

AWS SDKs and the AWS CLI refresh through that endpoint automatically. Static AWS
keys and SSO sessions never enter the workspace.

## Trust boundary

A Lobby project is the collaboration boundary: its agents and teammates share
the checkout, Docker daemon, and localhost services. Credential release is
narrower. Only the named managed-service process receives the binding; sibling
services and terminals receive neither its environment values nor its AWS
credential endpoint.

This is intentionally different from tools that inject a secret into an entire
agent VM. Treat the selected service and every dependency it loads as trusted with
that binding.

## Disable, replace, and remove

- **Disable** blocks new starts and refreshes. Stop and restart an already-running
  service for the change to take effect.
- **Replace values** rotates environment secrets without revealing the previous
  values.
- Rotating an AWS external ID requires installing the new trust statement,
  verifying it, and enabling the binding again.
- **Remove** deletes the binding from Lobby. An AWS STS session already issued to
  a running service can remain valid for up to one hour; change the customer role
  itself when AWS-side denial must be immediate.

## Network and private services

Credential bindings do not grant general network access. An AWS role service gets
the regional Secrets Manager endpoint required for its SDK credential flow.
PrivateLink, VPN, and private package-registry connectivity are separate network
features and are not configured by adding a credential binding.

## Verify the setup

Start the declared service from the workspace and check its normal health endpoint.
For AWS, call `aws sts get-caller-identity` or read one explicitly allowed test
secret without printing its value. Then confirm the same command fails from a
sibling service or interactive terminal. Disable the binding, stop the service,
and confirm a new start fails closed before using production-adjacent permissions.

# Identity and access
Source: https://docs.joinlobby.dev/identity-access

Access to repository work requires two independent checks: membership in the
selected Lobby account and the person's own permission to the GitHub repository.
Installing the Lobby GitHub App does not give every account member repository
access.

## Add and manage members

Open **Members** from Lobby to manage team membership and invitations.

- **Owners** can invite members and change joined members between member and admin.
- **Admins** can invite members.
- **Members** can collaborate within the repositories their own GitHub account permits.

Invitations are sent for the member role. The recipient must sign in with the
invited email address and accept before they join. If a person belongs to several
accounts, use the account switcher before opening team work.

## Connect repository access

An owner or administrator selects repositories when installing the Lobby GitHub
App. Each teammate then authorizes their own GitHub account. Lobby checks that
person's current repository permission when they open a conversation, send work,
use source control, access attachments, or publish.

Repository readers can inspect shared work and ask read-only questions. Repository
writers can edit and publish. A shared run cannot borrow broader rights from the
person who started it or from another contributor.

## Choose conversation visibility

Shared conversations are visible to members who also pass the repository check.
Private conversations are visible only to the person who created them and use an
isolated workspace. Shared project workspaces do not support private conversations.

## Remove access

Remove a person from the Lobby account and remove or reduce their GitHub
repository permission when both boundaries should close. Lobby rechecks GitHub
rights on protected operations and publication.

Some browser grants and live connections refresh on bounded intervals rather than
instantaneously. Removing active account membership during an already running
agent turn is not currently documented as immediate revocation. For urgent
containment, also revoke the underlying GitHub or customer-cloud permission and
stop the affected work.

Lobby does not currently provide customer SSO, SCIM, verified-domain enrollment,
or device policy. See [Teams and enterprise](/teams-enterprise) for the supported
rollout path.

# Projects And Tasks
Source: https://docs.joinlobby.dev/projects-tasks

## Use projects for shared outcomes

A project owns a durable Markdown brief and a task hierarchy. The brief holds goals,
constraints, and decisions that should survive individual conversations. Tasks hold
one concrete outcome, acceptance checks, status, assignment, and progress history.

## Work through task states

Tasks move through `Todo`, `In Progress`, `In Review`, and `Done`. Taking a task
records the active agent as owner; another agent cannot silently steal it. Mark work
done only after its acceptance checks and review are satisfied.

Each update uses the latest revision. If another person or agent changed the task,
Lobby rejects a stale update so the caller can reread and reconcile instead of
overwriting newer work.

## Keep progress in activity

Append verification, blockers, decisions, and handoffs as task comments. Comments
and status changes appear together in the activity stream. Project members see
member attribution; agent activity is linked to its conversation.

## Link conversations

Link a conversation to its primary task so the UI and other agents can recover the
work context. The link does not automatically change task status. Conversation,
project, repository, and author identity are supplied by Lobby rather than accepted
from agent input.

---

# Setup
Source: https://docs.joinlobby.dev/quickstart

## Sign in and select your organization

Open [Lobby](https://joinlobby.dev) and sign in with Google or an email code.
Complete your profile if prompted.

For team work, accept an invitation to your team's organization. Open **Members**
to check the current organization and manage invitations. A matching email
domain does not automatically join you to a team.

## Connect GitHub

Connect GitHub and install the Lobby GitHub App on the repositories you want
Lobby to access. GitHub access is separate from signing into Lobby. You do
not need to paste a personal access token.

Choose a repository from the repository list. If it is missing, check that the
GitHub App installation includes it and that you are using the intended account.

## Give the agent a task

Start a conversation in your repository and choose an available agent and model.
Give it a concrete outcome and a way to verify success. For example:

> Add a useful empty state to the project list. Follow the existing components,
> check it with an empty list, and record the interaction for review.

The cloud workspace starts when work is needed. Read the agent's progress and
send follow-up instructions in the same conversation.

## Review the result

Open source control and confirm the repository, worktree, and branch. Read the
changed files and diffs, then ask for any missing checks or corrections.
For a visible UI change, review a recording of the actual interaction.

Use **Commit** to save reviewed work in Git. Publishing is a separate step:
**Push** sends commits to GitHub, while **Create Pull Request** opens a review
for an already published branch. See [Review and publish changes](/source-control).

---

# Security and connectivity
Source: https://docs.joinlobby.dev/security-connectivity

Lobby runs agents in cloud workspaces. The account, repository, conversation,
and run determine what the control plane permits; the workspace receives scoped,
short-lived capabilities instead of control-plane or provider master credentials.

## Workspace boundaries

Private and disposable conversations use isolated MicroVMs. Shared project
conversations use a project host: members attached to the same project share its
branch checkout, Docker daemon, localhost network, and persistent volume. Treat
those members as trusted peers. File claims coordinate edits but do not prevent
every shell or background process from overwriting a peer's work.

Cloud workspaces allow the public development endpoints needed by the managed
sandbox. A customer-configurable VPN, private-network connector, IP allowlist, or
proxy/TLS-inspection setup is not currently exposed. Do not assume a cloud agent
can reach an internal source host, package registry, database, or API because a
member's own computer can reach it.

## Credentials and approvals

The GitHub clone credential is short-lived and restricted to the selected
repository. Model-provider credentials remain in the model gateway.

For a repository-managed development service, an owner or admin can configure a
supported AWS cloud role. Lobby assumes the customer role for up to one hour and
gives credentials only to that managed service through the standard AWS container
credential provider. The agent and interactive terminal do not receive the STS
keys. Disabling or rotating the binding blocks refresh; revoke the customer role
itself when an already-issued AWS session must stop immediately.

Keep application secrets out of repository files and prompts. Lobby can redact
credentials it issued, but it cannot reliably identify a secret fetched and
printed by application code.

## Storage and transport

Conversation attachments, demo videos, and workspace checkpoints are private,
account-scoped storage. Their storage buckets block public access and require TLS;
stored objects use AWS KMS encryption. Downloads and playback recheck account and
repository access. A shared demo URL does not grant access by itself.

## Regions and data location

Shared projects select a home region when created. The host, project disk,
snapshot, gateway, and runner logs stay in that region. The primary web service,
database, authentication, model providers, and source host may remain elsewhere.
Region selection is therefore compute locality, not complete data residency, and
changing a project's region is not currently supported.

## Enterprise capability status

Lobby does not currently document customer SSO or SCIM, audit-log or SIEM export,
customer-managed encryption keys, compliance attestations, customer private
networking, or endpoint-management policy. Treat those as unavailable unless a
new product guide explicitly describes setup and verification.

---

# Review And Publish
Source: https://docs.joinlobby.dev/source-control

## Select the work you are reviewing

Open source control and use the repository/worktree selector to choose the
conversation's working copy. Confirm the displayed branch before taking a Git
action. Repository history and a conversation's live worktree are different
views; choose the live worktree when reviewing uncommitted edits.

Inspect changed files and their diffs. Check the staged and unstaged changes,
and make sure the proposed commit contains only the intended work.

## Commit and push

Enter a commit message and choose **Commit** to save changes in the workspace's
Git history. A local commit is not yet published to GitHub.

**Commit options** also offers **Commit & Push**. Confirm the remote branch
in its dialog. If the commit succeeds but publishing fails, retry **Push**
after resolving the error; the commit already exists.

## More Git actions

| Action | What it does |
| --- | --- |
| Fetch | Updates remote history without changing your files. |
| Pull | Pulls updates into the current branch; diverged history stops without merging. |
| Push | Publishes commits to the remote branch you confirm. |
| Create Pull Request | Creates or opens a pull request for an already published branch. |
| Refresh | Reloads the source-control view. |

Resolve conflicts deliberately and preserve other people's changes. Check the
result after publishing, including the branch and any pull request checks.

---

# Teams and enterprise
Source: https://docs.joinlobby.dev/teams-enterprise

Lobby organizes work around an account and the GitHub repositories each person
is allowed to use. Start with a small team and one repository, verify the access
boundaries below, then expand the rollout.

## Roll out a team

1. **Choose an account owner.** The owner manages roles; owners and admins can invite members.
2. **Invite a pilot group.** Each person accepts the invitation using the invited email address and selects the team account.
3. **Connect one GitHub repository.** Install the Lobby GitHub App on selected repositories. Each person also needs their own GitHub authorization.
4. **Run a shared task.** Confirm the intended members can open the conversation, and that read-only and no-access users cannot edit or open it.
5. **Review the operating boundaries.** Decide whether Lobby's current workspace, network, credential, regional, and revocation behavior fits your requirements before adding more repositories.

Continue with [Identity and access](/identity-access) and
[Security and connectivity](/security-connectivity).

## Current administration model

| Concern | Current owner |
| --- | --- |
| Membership, invitations, roles, account switching | Lobby |
| Repository selection | Lobby GitHub App installation |
| Each person's repository permission | Their GitHub authorization |
| Conversation visibility | Shared by default; private conversations stay with their creator |
| Source publication | GitHub, after Lobby rechecks write access |
| Cloud workspace region | Selected when a shared project is created |

Lobby currently uses invitations and the owner, admin, and member roles described
in [Identity and access](/identity-access). It does not currently expose customer
SSO, SCIM, domain-based enrollment, audit-log export, or device-management policy.
Do not plan a deployment around those controls until they are documented here.

## Evaluate before a wider rollout

- Confirm which repositories the GitHub App may access and which people have personal access.
- Use private conversations for work that must not be visible to other account members.
- Treat people sharing a project workspace as trusted peers on its checkout, Docker daemon, localhost network, and persistent volume.
- Keep secrets out of repositories and agent prompts. Use supported managed-service credentials where available.
- Review [Security and connectivity](/security-connectivity) before relying on private services, data residency, or immediate revocation.
