This change introduces a refactor of the devcontainers recreation logic
which is now handled asynchronously rather than being request scoped.
The response was consequently changed from "No Content" to "Accepted" to
reflect this.
A new `Status` field was introduced to the devcontainer struct which
replaces `Running` (bool). This reflects that the devcontainer can now
be in various states (starting, running, stopped or errored).
The status field also protects against multiple concurrent recrations,
as long as they are initiated via the API.
Updates #16424
User name, avatar URL, and last seen at, are not required fields so they
can be empty. Instead of returning the 0 values from Go, we want to make
it more agnostic, and omit them when they are empty. This make the docs
and usage way clearer for consumers.

### Part 1:
Notes:
- `GetPresetsAtFailureLimit` SQL query is added, which is similar to
`GetPresetsBackoff`, they use same CTEs: `filtered_builds`,
`time_sorted_builds`, but they are still different.
- Query is executed on every loop iteration. We can consider marking
specific preset as permanently failed as an optimization to avoid
executing query on every loop iteration. But I decided don't do it for
now.
- By default `FailureHardLimit` is set to 3.
- `FailureHardLimit` is configurable. Setting it to zero - means that
hard limit is disabled.
### Part 2
Notes:
- `PrebuildFailureLimitReached` notification is added.
- Notification is sent to template admins.
- Notification is sent only the first time, when hard limit is reached.
But it will `log.Warn` on every loop iteration.
- I introduced this enum:
```sql
CREATE TYPE prebuild_status AS ENUM (
'normal', -- Prebuilds are working as expected; this is the default, healthy state.
'hard_limited', -- Prebuilds have failed repeatedly and hit the configured hard failure limit; won't be retried anymore.
'validation_failed' -- Prebuilds failed due to a non-retryable validation error (e.g. template misconfiguration); won't be retried.
);
```
`validation_failed` not used in this PR, but I think it will be used in
next one, so I wanted to save us an extra migration.
- Notification looks like this:

Dynamic params skip parameter validation in coder/coder.
This is because conditional parameters cannot be validated
with the static parameters in the database.

This change introduces a new `ParentId` field to the agent's manifest.
This will allow an agent to know if it is a child or not, as well as
knowing who the owner is.
This is part of the Dev Container Agents work
# Description
This PR adds the `worker_name` field to the provisioner jobs endpoint.
To achieve this, the following SQL query was updated:
-
`GetProvisionerJobsByOrganizationAndStatusWithQueuePositionAndProvisioner`
As a result, the `codersdk.ProvisionerJob` type, which represents the
provisioner job API response, was modified to include the new field.
**Notes:**
* As mentioned in
[comment](https://github.com/coder/coder/pull/17877#discussion_r2093218206),
the `GetProvisionerJobsByIDsWithQueuePosition` query was not changed due
to load concerns. This means that for template and template version
endpoints, `worker_id` will still be returned, but `worker_name` will
not.
* Similar to `worker_id`, the `worker_name` is only present once a job
is assigned to a provisioner daemon. For jobs in a pending state (not
yet assigned), neither `worker_id` nor `worker_name` will be returned.
---
# Affected Endpoints
- `/organizations/{organization}/provisionerjobs`
- `/organizations/{organization}/provisionerjobs/{job}`
---
# Testing
- Added new tests verifying that both `worker_id` and `worker_name` are
returned once a provisioner job reaches the **succeeded** state.
- Existing tests covering state transitions and other logic remain
unchanged, as they test different scenarios.

# Front-end Changes

Existing template versions do not have the metadata (modules + plan) in
the db. So revert to using static parameter information from the
original template import.
This data will still be served over the websocket.
This pull request allows coder workspace agents to be reinitialized when
a prebuilt workspace is claimed by a user. This facilitates the transfer
of ownership between the anonymous prebuilds system user and the new
owner of the workspace.
Only a single agent per prebuilt workspace is supported for now, but
plumbing has already been done to facilitate the seamless transition to
multi-agent support.

# Allow MCP server to run without authentication
This PR enhances the MCP server to operate without requiring authentication, making it more flexible for environments where authentication isn't available or necessary. Key changes:
- Replaced `InitClient` with `TryInitClient` to allow the MCP server to start without credentials
- Added graceful handling when URL or authentication is missing
- Made authentication status visible in server logs
- Added logic to skip user-dependent tools when no authenticated user is present
- Made the `coder_report_task` tool available with just an agent token (no user token required)
- Added comprehensive tests to verify operation without authentication
These changes allow the MCP server to function in more environments while still using authentication when available, improving flexibility for CI/CD and other automated environments.
PR contains:
- fix for claiming & deleting prebuilds with immutable params
- unit test for claiming scenario
- unit test for deletion scenario
The parameter resolver was failing when deleting/claiming prebuilds
because a value for a previously-used parameter was provided to the
resolver, but since the value was unchanged (it's coming from the
preset) it failed in the resolver. The resolver was missing a check to
see if the old value != new value; if the values match then there's no
mutation of an immutable parameter.

This PR adds Coder Connect support to `coder ssh --stdio`.
When connecting to a workspace, if `--force-new-tunnel` is not passed, the CLI will first do a DNS lookup for `<agent>.<workspace>.<owner>.<hostname-suffix>`. If an IP address is returned, and it's within the Coder service prefix, the CLI will not create a new tailnet connection to the workspace, and instead dial the SSH server running on port 22 on the workspace directly over TCP.
This allows IDE extensions to use the Coder Connect tunnel, without requiring any modifications to the extensions themselves.
Additionally, `using_coder_connect` is added to the `sshNetworkStats` file, which the VS Code extension (and maybe Jetbrains?) will be able to read, and indicate to the user that they are using Coder Connect.
One advantage of this approach is that running `coder ssh --stdio` on an offline workspace with Coder Connect enabled will have the CLI wait for the workspace to build, the agent to connect (and optionally, for the startup scripts to finish), before finally connecting using the Coder Connect tunnel.
As a result, `coder ssh --stdio` has the overhead of looking up the workspace and agent, and checking if they are running. On my device, this meant `coder ssh --stdio <workspace>` was approximately a second slower than just connecting to the workspace directly using `ssh <workspace>.coder` (I would assume anyone serious about their Coder Connect usage would know to just do the latter anyway).
To ensure this doesn't come at a significant performance cost, I've also benchmarked this PR.
<details>
<summary>Benchmark</summary>
## Methodology
All tests were completed on `dev.coder.com`, where a Linux workspace running in AWS `us-west1` was created.
The machine running Coder Desktop (the 'client') was a Windows VM running in the same AWS region and VPC as the workspace.
To test the performance of specifically the SSH connection, a port was forwarded between the client and workspace using:
```
ssh -p 22 -L7001:localhost:7001 <host>
```
where `host` was either an alias for an SSH ProxyCommand that called `coder ssh`, or a Coder Connect hostname.
For latency, [`tcping`](https://www.elifulkerson.com/projects/tcping.php) was used against the forwarded port:
```
tcping -n 100 localhost 7001
```
For throughput, [`iperf3`](https://iperf.fr/iperf-download.php) was used:
```
iperf3 -c localhost -p 7001
```
where an `iperf3` server was running on the workspace on port 7001.
## Test Cases
### Testcase 1: `coder ssh` `ProxyCommand` that bicopies from Coder Connect
This case tests the implementation in this PR, such that we can write a config like:
```
Host codercliconnect
ProxyCommand /path/to/coder ssh --stdio workspace
```
With Coder Connect enabled, `ssh -p 22 -L7001:localhost:7001 codercliconnect` will use the Coder Connect tunnel. The results were as follows:
**Throughput, 10 tests, back to back:**
- Average throughput across all tests: 788.20 Mbits/sec
- Minimum average throughput: 731 Mbits/sec
- Maximum average throughput: 871 Mbits/sec
- Standard Deviation: 38.88 Mbits/sec
**Latency, 100 RTTs:**
- Average: 0.369ms
- Minimum: 0.290ms
- Maximum: 0.473ms
### Testcase 2: `ssh` dialing Coder Connect directly without a `ProxyCommand`
This is what we assume to be the 'best' way to use Coder Connect
**Throughput, 10 tests, back to back:**
- Average throughput across all tests: 789.50 Mbits/sec
- Minimum average throughput: 708 Mbits/sec
- Maximum average throughput: 839 Mbits/sec
- Standard Deviation: 39.98 Mbits/sec
**Latency, 100 RTTs:**
- Average: 0.369ms
- Minimum: 0.267ms
- Maximum: 0.440ms
### Testcase 3: `coder ssh` `ProxyCommand` that creates its own Tailnet connection in-process
This is what normally happens when you run `coder ssh`:
**Throughput, 10 tests, back to back:**
- Average throughput across all tests: 610.20 Mbits/sec
- Minimum average throughput: 569 Mbits/sec
- Maximum average throughput: 664 Mbits/sec
- Standard Deviation: 27.29 Mbits/sec
**Latency, 100 RTTs:**
- Average: 0.335ms
- Minimum: 0.262ms
- Maximum: 0.452ms
## Analysis
Performing a two-tailed, unpaired t-test against the throughput of testcases 1 and 2, we find a P value of `0.9450`. This suggests the difference between the data sets is not statistically significant. In other words, there is a 94.5% chance that the difference between the data sets is due to chance.
## Conclusion
From the t-test, and by comparison to the status quo (regular `coder ssh`, which uses gvisor, and is noticeably slower), I think it's safe to say any impact on throughput or latency by the `ProxyCommand` performing a bicopy against Coder Connect is negligible. Users are very much unlikely to run into performance issues as a result of using Coder Connect via `coder ssh`, as implemented in this PR.
Less scientifically, I ran these same tests on my home network with my Sydney workspace, and both throughput and latency were consistent across testcases 1 and 2.

<summary> Refactoring Summary </summary>
### 1) `CalculateActions` Function
#### Issues Before Refactoring:
- Large function (~150 lines), making it difficult to read and maintain.
- The control flow is hard to follow due to complex conditional logic.
- The `ReconciliationActions` struct was partially initialized early,
then mutated in multiple places, making the flow error-prone.
Original source:
fe60b569ad/coderd/prebuilds/state.go (L13-L167)
#### Improvements After Refactoring:
- Simplified and broken down into smaller, focused helper methods.
- The flow of the function is now more linear and easier to understand.
- Struct initialization is cleaner, avoiding partial and incremental
mutations.
Refactored function:
eeb0407d78/coderd/prebuilds/state.go (L67-L84)
---
### 2) `ReconciliationActions` Struct
#### Issues Before Refactoring:
- The struct mixed both actionable decisions and diagnostic state, which
blurred its purpose.
- It was unclear which fields were necessary for reconciliation logic,
and which were purely for logging/observability.
#### Improvements After Refactoring:
- Split into two clear, purpose-specific structs:
- **`ReconciliationActions`** — defines the intended reconciliation
action.
- **`ReconciliationState`** — captures runtime state and metadata,
primarily for logging and diagnostics.
Original struct:
fe60b569ad/coderd/prebuilds/reconcile.go (L29-L41)

Adds a new hidden subcommand `coder connect exists <hostname>` that checks if the name exists via Coder Connect. This will be used in SSH config to match only if Coder Connect is unavailable for the hostname in question, so that the SSH client will directly dial the workspace over an existing Coder Connect tunnel.
Also refactors the way we inject a test DNS resolver into the lookup functions so that we can test from outside the `workspacesdk` package.
This change allows listing both predefined and runtime-detected
devcontainers, as well as showing whether or not the devcontainer is
running and which container represents it.
Fixescoder/internal#478
https://github.com/coder/coder/pull/17163 introduced the
`workspace_app_statuses` table. Two of these fields
(`needs_user_attention`, `icon`) turned out to be surplus to
requirements.
- Removes columns `needs_user_attention` and `icon` from
`workspace_app_statuses`
- Marks the corresponding fields of `codersdk.WorkspaceAppStatus` as
deprecated.
- Removes displaying XRay scan results in the dashboard. I'm not sure
anyone was even using this integration so it's just debt for us to
maintain. We can open up a separate issue to get rid of the db tables
once we know for sure that we haven't broken anyone.
Fixes two issues with the MCP server:
- Ensures we have a non-null schema, as the following schema was making
claude-code unhappy:
```
"inputSchema": { "type": "object", "properties": null },
```
- Skip adding the coder_report_task tool if an agent client is not
available. Otherwise the agent may try to report tasks and get confused.
- Refactors existing `mcp` package to use `kylecarbs/aisdk-go` and moves
to `codersdk/toolsdk` package.
- Updates existing MCP server implementation to use `codersdk/toolsdk`
