# Getting Started

This guide walks platform teams and administrators through enabling Coder
Agents, preparing your deployment, and running your first Coder Agent.

> [!NOTE]
> Coder Agents is in [Early Access](./early-access.md). Deploy to a
> **test or development environment** — not production — while evaluating
> the feature.

## Prerequisites

Before you begin, confirm the following:

- **Coder deployment** running the latest release with the `agents`
  experiment flag available.
- **LLM provider credentials** — an API key for at least one
  [supported provider](./models.md) (Anthropic, OpenAI, Google, Azure OpenAI,
  AWS Bedrock, OpenAI Compatible, OpenRouter, or Vercel AI Gateway).
- **Network access** from the control plane to your LLM provider. Workspaces
  do not need LLM access — only the control plane does.
- **At least one template** with a
  [descriptive name and description](./platform-controls/template-optimization.md)
  for the agent to select when provisioning workspaces.
- **Admin access** to the Coder deployment for enabling the experiment and
  configuring providers.
- **Coder Agents User role** assigned to each user who needs to interact with Coder Agents.
  Owners can assign this from **Admin** > **Users**. See
  [Grant Coder Agents User](#step-3-grant-coder-agents-user) below.

## Step 1: Enable the experiment

Coder Agents is gated behind the `agents` experiment flag. Pass it when
starting the Coder server:

```sh
CODER_EXPERIMENTS="agents" coder server
# or
coder server --experiments=agents
```

If you already use other experiments, add `agents` to the comma-separated list:

```sh
CODER_EXPERIMENTS="agents,oauth2,mcp-server-http" coder server
```

See [Enable Coder Agents](./early-access.md#enable-coder-agents) for full
details.

## Step 2: Configure an LLM provider and model

> [!IMPORTANT]
> Configuring providers, models, and system prompts requires the
> **Owner** role (Coder administrator). Non-admin users cannot access the
> Admin panel or modify deployment-level Agents configuration.

Once the server restarts with the experiment enabled:

1. Navigate to the **Agents** page in the Coder dashboard.
1. Click **Admin** to open the configuration dialog.
1. Under the **Providers** tab, select a provider, enter your API key, and
   save.
1. Switch to the **Models** tab, click **Add**, and configure at least one
   model with its identifier, display name, and context limit.
1. Click the **star icon** next to a model to set it as the default.

Detailed instructions for each provider and model option are in the
[Models](./models.md) documentation.

> [!TIP]
> Start with a single frontier model to validate your setup before adding
> additional providers.

## Step 3: Grant Coder Agents User

The **Coder Agents User** role controls which users can interact with Coder Agents.
Members do not have Coder Agents User by default.

Owners always have full access and do not need the role. Repeat the following steps for each user who needs access.

> [!NOTE]
> Users who created conversations before this role was introduced are
> automatically granted the role during upgrade.

**Dashboard (individual):**

1. Go to **Admin** > **Users** in the Coder dashboard.
1. Click the roles icon next to the user you want to grant access to.
1. Enable the **Coder Agents User** role and save.

**CLI (bulk):**

You can also grant the role via CLI. For example, to grant the role to
all active users at once:

```sh
coder users list -o json \
  | jq -r '.[].username' \
  | while read u; do
      coder users edit-roles "$u" \
        --roles "$(coder users show "$u" -o json \
          | jq -r '[.roles[].name, "agents-access"] | unique | join(",")')" \
        --yes
    done
```

## Step 4: Start your first Coder Agent

1. Go to the **Agents** page in the Coder dashboard.
1. Select a model from the dropdown (your default will be pre-selected).
1. Type a prompt and send it.

The agent processes the prompt in the control plane. If the task requires
a workspace — reading files, running commands, editing code — the agent
selects a template and provisions one automatically. Conversations that
don't require compute (planning, Q&A, architecture discussions) start
immediately with no provisioning delay.

## Optimize your templates

The agent selects templates based on their **name and description** — it does
not read Terraform. Clear, specific descriptions are the most important factor
in whether the agent picks the right template.

Update your template descriptions to include:

- The language, framework, or stack the template targets.
- Which repository or service it is for, if applicable.
- What type of work it supports (backend, frontend, data pipeline, etc.).

**Good examples:**

| Description                                                                                 | Why it works                                 |
|---------------------------------------------------------------------------------------------|----------------------------------------------|
| Python backend services for the payments repo. Includes Poetry, Python 3.12, and PostgreSQL | Specific language, repo, and toolchain       |
| React frontend development for the customer portal. Node 20, pnpm, Storybook pre-installed  | Clear stack, named project, key tools listed |
| General-purpose Go development environment with Go 1.23, Docker, and common CLI tools       | Broad but descriptive                        |

**Descriptions to avoid:**

| Description        | Problem                                         |
|--------------------|-------------------------------------------------|
| Team A template v2 | No information about what the template is for   |
| Dev environment    | Too generic to distinguish from other templates |
| Default            | Tells the agent nothing                         |

See [Template Optimization](./platform-controls/template-optimization.md) for
the full guide, including dedicated agent templates, network boundaries,
credential scoping, and pre-installing dependencies.

## Things to know before you start

### Deploy to a non-production environment

Coder Agents is under active development. APIs, behavior, and configuration
may change between releases without notice. Run your evaluation on a
dedicated test or staging deployment to avoid disruption to production
developer workflows. See [Early Access](./early-access.md) for the full
set of expectations and limitations.

### Use HTTPS for push notifications

Coder Agents use browser push notifications to alert you when a task
completes or needs attention. Most browsers require a secure (HTTPS)
origin for the [Push API](https://developer.mozilla.org/en-US/docs/Web/API/Push_API)
to work. If your access URL uses plain HTTP,
push notifications may not function.

This does not affect agents themselves — only the browser notification
delivery. If you terminate TLS at a reverse proxy, ensure the
[access URL](../../admin/setup/index.md) is configured with an `https://` scheme.

### Set a deployment-wide system prompt

Administrators can set a system prompt that applies to all Coder Agents across the
deployment. Use this to encode organizational conventions:

- Coding standards and style guidelines.
- Commit message formats.
- Branch naming conventions.
- Required review processes before merging.
- Any guardrails specific to your environment.

Configure the system prompt from the **Admin** dialog on the Agents page
or via the API at `PUT /api/experimental/chats/config/system-prompt`.
See [Platform Controls](./platform-controls/index.md) for details.

### Understand the security model

The agent runs in the control plane, not inside workspaces. This means:

- **No LLM API keys in workspaces.** Credentials stay in the control plane.
- **No agent software in workspaces.** No supply chain risk from
  third-party agent tools.
- **User identity is always attached.** Every action is tied to the user
  who submitted the prompt — no shared bot accounts.
- **No privilege escalation.** The agent has exactly the same permissions
  as the prompting user.

Agent workspaces inherit the same network access as any manually created
workspace. If your templates don't restrict egress, the agent has full
internet access from the workspace. Consider
[creating dedicated agent templates](./platform-controls/template-optimization.md#create-dedicated-agent-templates)
with tighter network policies.

### Plan for LLM costs

Every conversation turn sends tokens to your LLM provider. Long-running tasks,
sub-agent delegation, and complex multi-step work can consume significant
token volume. Consider:

- Starting with a single model to establish a cost baseline.
- Setting per-model token pricing in the admin panel (Input Price, Output
  Price) to track spend.
- Monitoring provider dashboards for usage trends during the evaluation.

### Pilot with a small group

Identify 3–5 developers and a few concrete use cases for the initial rollout.
Good starting points:

- **Low-risk, high-visibility tasks** — generating unit tests, writing inline
  documentation, small refactors.
- **Investigation and triage** — exploring unfamiliar code, triaging bugs,
  understanding legacy systems.
- **Prototyping** — building proof-of-concept implementations, simple
  dashboards, internal tools.

Set expectations that this is an evaluation period. Developers should still
review all agent-produced code before merging. The agent is a force
multiplier, not a replacement for developer judgment.

### Use the API for programmatic automation

The [Chats API](./chats-api.md) enables programmatic access to Coder Agents.
This is useful for building automations such as:

- Triggering Coder Agents from CI/CD pipelines when builds fail.
- Creating Coder Agents from GitHub webhooks on new issues or PRs.
- Building internal tools or dashboards on top of the API.
- Scripting batch operations across repositories.

**Quick example — create a Coder Agent via the API:**

```sh
curl -X POST https://coder.example.com/api/experimental/chats \
  -H "Coder-Session-Token: $CODER_SESSION_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "content": [
      {"type": "text", "text": "Fix the failing tests in the auth service"}
    ]
  }'
```

Stream updates in real time by connecting to the WebSocket endpoint:

```text
GET /api/experimental/chats/{chat}/stream
```

For service-to-service automation, use
[API keys](../../admin/users/sessions-tokens.md)
rather than developer session tokens. Keep automation credentials
narrowly scoped.

> [!NOTE]
> The Chats API is experimental and may change without notice.
> See [Chats API](./chats-api.md) for the full endpoint reference.

### Add workspace context with AGENTS.md

Create an `AGENTS.md` file in the home directory (`~/.coder/AGENTS.md`) or
the workspace agent's working directory to provide persistent context to the
agent. This file is automatically read and included in the system prompt
for every conversation with a Coder Agent that uses that workspace.

Use it for:

- Repository-specific build and test instructions.
- Important architectural decisions or constraints.
- Links to relevant documentation or runbooks.
- Any context that helps the agent work effectively in that codebase.

### Consider prebuilt workspaces for faster startup

Workspace provisioning is the main source of latency when the agent starts a
task. If your templates take more than a minute to provision, consider
configuring
[prebuilt workspaces](../../admin/templates/extending-templates/prebuilt-workspaces.md)
to maintain a pool of ready-to-use workspaces. The agent gets assigned an
already-running workspace instead of provisioning from scratch.

## Providing feedback

Coder Agents is a collaborative evaluation between your team and Coder.
Share feedback — workflow observations, feature requests, bugs, performance
issues, or operational challenges — through your **customer-specific Slack
channel** with the Coder team.

Good feedback includes:

- **What you tried** — the prompt, the template, and the model.
- **What happened** — the agent's behavior, any errors, unexpected results.
- **What you expected** — the outcome you were looking for.
- **Context** — screenshots, `chat_id` values, or links to the Agents page help
  the team investigate quickly.

Your input directly influences product direction during Early Access.
