The "Task app is not ready to accept input" error occurs when the
agent responds successfully but its status is not "stable" (e.g.
"running"). This is a state conflict, not a gateway error. 502 was
semantically wrong because the gateway communication succeeded.
409 Conflict is correct because the request conflicts with the
agent's current state. This is consistent with how
authAndDoWithTaskAppClient already returns 409 for pending,
initializing, and paused agent states.
Since Go 1.22, the loop variable capture issue is resolved. Variables
declared by for loops are now per-iteration rather than per-loop, making
the 'v := v' pattern unnecessary.
Closes https://github.com/coder/internal/issues/1261.
This pull request adds an endpoint to pause coder tasks by stopping the
underlying workspace.
* Instead of `POST /api/v2/tasks/{user}/{task}/pause`, the endpoint is
currently experimental.
* We do not currently set the build reason to `task_manual_pause`,
because build reasons are currently only used on stop transitions.
Previously we returned 400 Bad Request for all non-active states. This
was semantically incorrect for transitional and paused states where the
request is valid but conflicts with current state.
We now return 409 Conflict for pending/initializing/paused (resolvable
by waiting or resuming) and 400 for error/unknown (actual problems).
This enables client-side auto-resume orchestration per the task
lifecycle RFC.
Closescoder/internal#1265
Task snapshots were orphaned when tasks were soft-deleted. The
`task_snapshots` table has an `ON DELETE CASCADE` foreign key, but
that only fires on hard deletes.
Modified DeleteTask to use a CTE that atomically soft-deletes the
task and removes its snapshot in a single transaction. The query now
returns just the task UUID instead of the full row.
Closescoder/internal#1283
Previously the task logs endpoint only worked when the workspace was
running, leaving users unable to view task history after pausing.
This change adds snapshot retrieval with state-based branching: active
tasks fetch live logs from AgentAPI, paused/initializing/pending tasks
return stored snapshots (providing continuity during pause/resume), and
error/unknown states return HTTP 409 Conflict.
The response includes snapshot metadata (snapshot, snapshot_at) to
indicate whether logs are live or historical.
Closescoder/internal#1254
This change adds a POST /workspaceagents/me/tasks/{task}/log-snapshot
endpoint for agents to upload task conversation history during
workspace shutdown. This allows users to view task logs even when the
workspace is stopped.
The endpoint accepts agentapi format payloads (typically last 10
messages, max 64KB), wraps them in a format envelope, and upserts to the
task_snapshots table. Uses agent token auth and validates the task
belongs to the agent's workspace.
Closescoder/internal#1253
This removes the deprecated AITaskPromptParameterName constant and all
backward compatibility code that was added for v2.28.
- Remove AITaskPromptParameterName constant from codersdk/aitasks.go
- Remove backward compatibility code in coderd/aitasks.go that populated
the "AI Prompt" parameter for templates that defined it
- Remove the backward compatibility test (OK AIPromptBackCompat)
- Update dbfake to no longer set the AI Prompt parameter
- Remove AITaskPromptParameterName from frontend TypeScript types
- Remove preset prompt read-only feature from TaskPrompt component
- Update docs to reflect that pre-2.28 definition is no longer supported
Task prompts are now exclusively stored in the tasks.prompt database
column, as introduced in the migration that added the tasks table.
Provisioner steps broken into smaller granular actions.
Changes:
- `ExtractArchive` moved to `init` request (was in `configure`)
- Writing `tfstate` moved to `plan` (was in `configure`)
- Moved most plan/apply outputs to `GraphComplete`
Closes https://github.com/coder/internal/issues/1178
I verified the fix works by adding a `time.Sleep(100 *time.Millisecond)`
between the `CreateWorkspaceBuild` and`CancelWorkspaceBuild`
calls. Adding this reliably triggered the flake, and when I added the fix
the flake stopped happening.
## Problem
Tasks currently only expose a machine-friendly name field (e.g.
`task-python-debug-a1b2`), but this value is primarily an identifier
rather than a clean, descriptive label. We need a separate
display-friendly name for use in the UI.
This PR introduces a new `display_name` field and updates the task-name
generation flow. The Claude system prompt was updated to return valid
JSON with both `name` and `display_name`. The name generation logic
follows a fallback chain (Anthropic > prompt sanitization > random
fallback). To make task names more closely resemble their display names,
the legacy `task-` prefix has been removed. For context, PR
https://github.com/coder/coder/pull/20834 introduced a small Task icon
to the workspace list to help identify workspaces associated to tasks.
## Changes
- Database migration: Added `display_name` column to tasks table
- Updated system prompt to generate both task name and display name as
valid JSON
- Task name generation now follows a fallback chain: Anthropic > prompt
sanitization > random fallback
- Removed `task-` prefix from task names to allow more descriptive names
- Note: PR https://github.com/coder/coder/pull/20834 adds a Task icon to
workspaces in the workspace list to distinguish task-created workspaces
**Note:** UI changes will be addressed in a follow-up PR

## Problem
With the new tasks data model, a task starts with an `initializing`
status. However, the API returns `current_state: null` to represent the
agent state, causing the frontend to display "No message available".
This PR updates `codersdk.Task` to return a `current_state` when the
task is initializing with meaningful messages about what's happening
during task initialization.

## Changes
- Populate `current_state` with descriptive initialization messages when
task status is `initializing` and no valid app status exists for the
current build
- **dbfake**: Fix `WorkspaceBuild` builder to properly handle
pending/running jobs by linking tasks without requiring agent/app
resources
**Note:** UI Storybook changes to reflect these new messages will be
addressed in a follow-up PR.

Currently AgentAPI waits for only 2 seconds worth of identical terminal
screen snapshots before deciding a task has entered a "stable" state. We
interpret this as becoming "idle", resulting in a notification being
triggered. This behavior is not ideal and is ultimately the root cause
of our spammy notifications.
Unfortunately, until we move AgentAPI to either use the Claude Code SDK
(or ACP wrapper around it), we are unable to easily fix the root cause.
This PR instead waits until the agent is ready before it will send state
change notifications. This will at least resolve _some_ of the
complaints about task state notifications being too spammy.

* Adds a `GetTaskByOwnerIDAndName` query
* Updates `httpmw.TaskParam` to fall back to task name if no task by
UUID found.
* Updates the `TaskByIdentifier` used in `cli/` to use direct lookup instead of searching.
* Instead of prompting the user to start a deleted workspace (which is
silly), prompt them to create a new task instead.
* Adds a warning dialog when deleting a workspace
* Updates provisionerdserver to delete the related task if a workspace
is related to a task
Updates the UI to use the new API endpoints for tasks and use its new
data model.
Disclaimer: Since the base data model for tasks changed, we had to do a
quite large refactor and I'm sorry for that 🙏, but you'll notice most of
the changes are to adjust the types.

I find the "task is working" notification straight after creation to be
unnecessary.
Added logic to skip the notification if the first app status is
"working".
Reverts coder/coder#20181
I realized we don’t need this in the task response. When loading a task,
we already need much more workspace information, so it makes more sense
to fetch the workspace data separately instead of trying to embed all
its details into the response.
I think we can keep the task response clean and focused on the essential
information needed to list tasks. For more specific details, we can
fetch the related resources as needed. So, I’m reverting this PR.
## Description
Send a notification to the workspace owner when an AI task’s app state
becomes `Working` or `Idle`.
An AI task is identified by a workspace build with `HasAITask = true`
and `AITaskSidebarAppID` matching the agent app’s ID.
## Changes
* Add `TemplateTaskWorking` notification template.
* Add `TemplateTaskIdle` notification template.
* Add `GetLatestWorkspaceAppStatusesByAppID` SQL query to get the
workspace app statuses ordered by latest first.
* Update `PATCH /workspaceagents/me/app-status` to enqueue:
* `TemplateTaskWorking` when state transitions to `working`
* `TemplateTaskIdle` when state transitions to `idle`
* Notification labels include:
* `task`: task initial prompt
* `workspace`: workspace name
* Notification dedupe: include a minute-bucketed timestamp (UTC
truncated to the minute) in the enqueue data to allow identical content
to resend within the same day (but not more than once per minute).
Closes: https://github.com/coder/coder/issues/19776
This changes the task get endpoint to omit app statuses for previous
'lifetimes' of a workspace.
It also introduces a [breaking
change](https://github.com/coder/coder/blob/release/2.26/codersdk/aitasks.go#L83)
to bring `TaskStateComplete` in line with
`WorkspaceAppStatusStateComplete`. I can alternatively revert this
change and add a conversion function between the two SDK types.
Due to how we currently label a workspace as a task, there is a delay
between when a task workspace is created and when it is labelled as a
task.
This PR introduces fallback check for when a workspace does _not_ have
`HasAITask` set. This fallback check tests to see if the special "AI
Prompt" parameter is present in the workspace's build parameters.
