Ethan ef0151601e feat: report insufficient quota build failures in chat tools (#24956)
## Summary

When a workspace build fails because the user is over their group quota,
the chat tools currently surface the failure as a bare `"workspace build
failed: insufficient quota"` string with no machine-readable error code
and no visibility into the user's current usage. Agents and the UI
cannot distinguish quota failures from any other Terraform error, so
users see an opaque message and have no clear path to recovery.

This PR tags quota failures with a typed error code at the source and
propagates it through the chat tool layer so callers can react to it
explicitly.

Relates to CODAGT-20

## Changes

**Provisioner runner**

- Add `InsufficientQuotaErrorCode = "INSUFFICIENT_QUOTA"` and set it
explicitly at the `commitQuota` failure site via a new
`failedWorkspaceBuildfCode` helper, so `provisioner_jobs.error_code` is
populated only on the genuine quota path. The substring matcher used for
externally produced sentinels (e.g. `"missing parameter"`, `"required
template variables"`) is intentionally not extended; provider errors
that happen to mention "insufficient quota" stay classified as generic
build failures.

**SDK and API contract**

- Add `JobErrorCodeInsufficientQuota` and a
`JobIsInsufficientQuotaErrorCode` helper to `codersdk`.
- Extend the swagger `enums` tag on `ProvisionerJob.ErrorCode` to
include `INSUFFICIENT_QUOTA`.
- Regenerate `coderd/apidoc`, `docs/reference/api/*`, and
`site/src/api/typesGenerated.ts`.

**chattool create_workspace / start_workspace**

- `waitForBuild` now returns a typed `*workspaceBuildError` carrying
both the message and the `JobErrorCode`, instead of a bare error string.
- New `quotaerror.go` introduces a structured `quotaErrorResult` (with
`error_code`, `title`, `message`, `build_id`, and optional `quota`) and
a best-effort `workspaceQuotaDetails` lookup that wraps owner
authorization internally and fetches `credits_consumed` and `budget`
from the database. Quota lookup failures (including authorization
failures) never block the failure payload.
- On quota-coded build failures, both `create_workspace` and
`start_workspace` now return the structured response (with the recovery
guidance inlined into `message`) instead of the bare `"insufficient
quota"` string. This applies to all three failure paths: post-creation,
an in-progress existing build, and a freshly triggered start build.
Non-quota build failures continue to use the existing
`buildToolResponse` / `newBuildError` path.
- Owner authorization is wrapped only on the call sites that need it
(the `CreateFn` and `StartFn` invocations and the quota-detail lookup),
so idempotent fast paths (already running, already in progress,
existing-workspace early returns) do not pay for an extra RBAC
round-trip or fail when role lookup is transient.

## Out of scope

- No changes to quota math, allowances, or bypass behavior.
- No automatic retries.
- No new quota-inspection tools and no changes to MCP
`coder_create_workspace` (which returns immediately and never observed
the build outcome here).
- No frontend UI changes; those will land in a follow-up PR that
consumes the new `INSUFFICIENT_QUOTA` code.

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.
