Closes [CODAGT-317](https://linear.app/codercom/issue/CODAGT-317/pr-workspaces-sometimes-require-name-confirmation-to-delete). ## Problem The `/agents` archive-and-delete molly-guard (typing the workspace name) was firing for chats that had clearly created their own workspace. The heuristic in `resolveArchiveAndDeleteAction` decides whether confirmation is needed by comparing the workspace's `created_at` against the chat's `created_at`: ```ts return new Date(workspaceCreatedAt) >= new Date(chatCreatedAt); ``` That assumption breaks for **prebuilt workspaces**. `ClaimPrebuiltWorkspace` rewrites `owner_id`, `name`, `updated_at`, `last_used_at`, etc., but **never touches `created_at`**, which still reflects when the prebuild was provisioned by the reconciler, often hours before the chat exists. Result: every prebuild-claimed workspace looks pre-existing, so the molly-guard fires. Concrete example from a real chat: | Field | Value | |---|---| | `chat.created_at` | `2026-05-07T15:12:23Z` | | `workspace.created_at` (provision) | `2026-05-07T14:22:24Z` | | `latest_build.created_at` (claim) | `2026-05-07T15:19:09Z` | `14:22:24 < 15:12:23` so `isWorkspaceAutoCreated` returned false even though the chat issued the claim. ## Fix (frontend-only) Derive the moment a workspace was acquired from existing build history rather than relying on `workspace.created_at`: - Build #1 initiator = prebuilds system user → workspace was a prebuild → use `build_2.created_at` (the claim build) as the acquisition time. - Build #1 initiator = real user → workspace was created from scratch → use `workspace.created_at` (unchanged behavior). - Unclaimed prebuild or no build history → return `null` (force confirmation; safe degradation for a destructive flow). The resolver fetches the build list via the existing `getWorkspaceBuilds` endpoint when the dialog might fire. No new column, no migration, no schema change. Works retroactively for all existing claimed prebuilds; no backfill needed. The prebuilds system user UUID is exposed via `codersdk.PrebuildsSystemUserID` and typegen'd to `typesGenerated.ts`. `coderd/database.PrebuildsSystemUserID` parses that constant via `uuid.MustParse` so the two cannot drift; if the codersdk literal ever changes, package init fails fast. ## History The first draft of this PR added a `workspaces.claimed_at` column populated by `ClaimPrebuiltWorkspace`. After review feedback from @johnstcn pointing out that the same fact is already implicit in build history, I pivoted to the frontend-only approach. Subsequent review notes consolidated the prebuilds system user UUID into a single typegen'd constant. ## Why not the other open PRs - **#25055** (`chatKey` cache fallback) only fixes a different cache-miss path; it explicitly notes it does not address `created_at < chat.created_at`. - **#25053** (`chats.workspace_auto_created` boolean) puts the truth on the wrong side of the schema: "this workspace was claimed at time T" is a property of the workspace, not the chat. The MCP plumbing it adds is also unnecessary now that the same answer is available from build history. ## Test plan - `pnpm vitest run --project=unit src/pages/AgentsPage/utils/agentWorkspaceUtils.test.ts` — 40/40 pass; new cases cover prebuild claim before/after chat, unclaimed prebuild, missing-build-history fallback, and the fetch-skip when the chat is not in cache. - `pnpm lint:types`, `pnpm check`, `make pre-commit`. <details> <summary>Disclosure</summary> Opened on behalf of @kylecarbs by [Coder Agents](https://coder.com/coder-agents). </details>
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
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.
