8b970e7ff3 docs: clarify Agents vs Chats API reference pages (#26021)
## Problem

The REST API reference page at
[`/docs/reference/api/agents`](https://coder.com/docs/reference/api/agents)
is confusing: by the name alone, a reader looking for the *AI Coder
Agents* programmatic API would assume this is the right page. In fact,
those endpoints are for the *workspace agent daemon* (the `coder_agent`
Terraform resource / `workspaceagent` daemon). The actual AI Coder
Agents API is documented at
[`/docs/reference/api/chats`](https://coder.com/docs/reference/api/chats).

Both pages compound the confusion by being rendered with a bare `#
Agents` / `# Chats` heading and no descriptive intro. The sidebar
entries are similarly ambiguous (`Agents` and `Chats` with no
descriptions).

## Root cause

The reference pages are generated by `scripts/apidocgen/generate.sh`
(swag → widdershins → postprocess). The widdershins template
(`scripts/apidocgen/markdown-template/main.dot`) already renders
`data.resource.description` directly under each section heading:

```
<!-- APIDOCGEN: BEGIN SECTION -->
{{= data.tags.section }}# {{= r}}

{{? data.resource.description }}{{= data.resource.description}}{{?}}
```

…but the swag annotations in `coderd/coderd.go` never declared
`@tag.name` / `@tag.description` for any tag, so the descriptions were
always empty.

## Changes

- `coderd/coderd.go`: add `@tag.name Agents` / `@tag.description …` and
`@tag.name Chats` / `@tag.description …` annotations next to the
existing `@title` / `@version` block.
- `docs/manifest.json`: rename the sidebar entry `Agents` → `Workspace
Agents` and add `description` fields to both API sidebar entries (every
other top-level section in the manifest has descriptions; the API
children did not).
- Regenerate `coderd/apidoc/swagger.json`, `coderd/apidoc/docs.go`,
`docs/reference/api/agents.md`, and `docs/reference/api/chats.md` via
`scripts/apidocgen/generate.sh` + `pnpm exec markdownlint-cli2 --fix` +
`pnpm exec markdown-table-formatter` + `scripts/biome_format.sh`
(matching the Makefile's `coderd/apidoc/.gen` pipeline).

Resulting diff is intentionally minimal — 6 files, 35 insertions / 3
deletions.

## After this PR

The Agents page will render:

> # Agents
>
> Workspace agent endpoints. These power the workspace agent daemon
defined by the `coder_agent` Terraform resource (sometimes called the
workspace daemon). This API is NOT the AI Coder Agents API. For
programmatic access to AI Coder Agents (formerly Tasks), see the Chats
API.

The Chats page will render:

> # Chats
>
> Programmatic API for Coder AI Agents (the user-facing "Coder Agents" /
"Chats" product). Experimental. Use these endpoints to create, list, and
manage AI coding agent sessions. For background and migration from the
Tasks API, see the AI Coder docs.

And the sidebar entry for the workspace-agent endpoints becomes
`Workspace Agents` instead of `Agents`.

## Out of scope (potential follow-ups)

- `docs/reference/api/chat.md` is a 7-byte stub — likely dead. Could be
deleted in a follow-up.
- Larger rename of the `Agents` Swagger tag (and/or the `coder_agent`
Terraform resource) to something like `Workspace Agents` /
`workspace_daemon` would more thoroughly fix the naming collision, but
that's a much bigger change.

Coder is a self-hosted platform for cloud development environments and AI coding agents. Workspaces are defined with Terraform, connected through a secure Wireguard® tunnel, and automatically shut down when not used. Coder Agents runs a native AI coding agent whose loop executes in the control plane on your infrastructure, with no API keys in workspaces.

  • Define cloud development environments in Terraform
    • EC2 VMs, Kubernetes Pods, Docker Containers, etc.
  • Automatically shutdown idle resources to save on costs
  • Onboard developers in seconds instead of days
  • Delegate coding work to AI agents on your infrastructure
    • Bring any model (Anthropic, OpenAI, Google, Bedrock, self-hosted)
    • No LLM credentials in workspaces, user identity on every action
    • Centralized model governance, cost tracking, and audit logging

Coder platform showing templates and a running workspace

Quickstart

The most convenient way to try Coder is to install it on your local machine and experiment with provisioning cloud development environments using Docker (works on Linux, macOS, and Windows).

# First, install Coder
curl -L https://coder.com/install.sh | sh

# Start the Coder server (caches data in ~/.cache/coder)
coder server

# Navigate to http://localhost:3000 to create your initial user,
# create a Docker template and provision a workspace

Install

The easiest way to install Coder is to use the install script for Linux and macOS. For Windows, use the latest ..._installer.exe file from GitHub Releases.

curl -L https://coder.com/install.sh | sh

You can run the install script with --dry-run to see the commands that will be used to install without executing them. Run the install script with --help for additional flags.

See install for additional methods.

Once installed, you can start a production deployment with a single command:

# Automatically sets up an external access URL on *.try.coder.app
coder server

# Requires a PostgreSQL instance (version 13 or higher) and external access URL
coder server --postgres-url <url> --access-url <url>

Use coder --help to get a list of flags and environment variables. See the install guides for a complete tutorial.
