Michael Suchacz ba5717dc67 fix(site/src/pages/AgentsPage): disallow queued message edits (#28265)
Closes CODAGT-230.

Selecting "Edit queued message" in Agent Chat did not stop the queued
message from sending: edit mode was purely client-side state, so at turn
end the backend promoted the queued message and sent it anyway, leaving
the UI stuck in a stale "Editing queued message" state with the send
button showing "Save".

This removes queued-message editing entirely instead of adding backend
locking. Queued messages can still be promoted ("Send now") and deleted
("Remove from queue"); editing already-sent history messages is
unchanged.

## Changes

- Remove the Edit pencil from queued message rows
(`QueuedMessagesList`), the "Editing queued message" banner and "Save"
button label (`AgentChatInput`), and the queue-edit state, handlers, and
prop plumbing (`AgentChatPage`, `AgentChatPageView`, `ChatPageContent`).
- Remove the queued-edit save flow that deleted the original queued row
and re-queued a new message, plus the now-unused `rawText`/`fileBlocks`
fields of `getQueuedMessageInfo`.
- Drop the redundant `isEditingHistoryMessage` prop on `ChatPageInput`,
which had become identical to `isEditing`, and stop discarding the
delete/promote promises so `QueuedMessagesList` busy state works again.
- Replace the queued-edit stories and tests with an `ActionsExcludeEdit`
regression story asserting queued rows expose "Send now" and "Remove
from queue" but no "Edit" button.

## Testing

- `pnpm -C site check`, `pnpm -C site lint:types`.
- Unit: `AgentChatPage.test.ts`, `QueuedMessagesList.test.ts` (92
tests). Storybook: all four touched story files (102 tests). A
pre-existing unhandled xterm error in `AgentChatPageView.stories.tsx`
reproduces identically at the merge base.
- Remote dogfood UAT passed on a dev.coder.com workspace with a real
model: no edit affordance on queued rows, queued delete and turn-end
promotion still work, history-message editing and Escape behavior
unaffected.

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.
