fix: stop rerunning AI prompt when task workspace is restarted #20225
Description
Description
Customers have identified that with a Task Workspace, when it is restarted or started up after being shut down, the original prompt will rerun. The prompt rerunning can cause unexpected behaviour in
- Increase in billing as you're unnecessarily calling AI tooling
- The agent ignoring previously made progress, potentially overwriting work
On restart, Tasks shouldn't rerun the prompt. See Slack for the original issue.

Discussed in yesterday's standup: as an interim workaround, we're going to add a warning message when restarting a task workspace or starting from a stopped state.
@david-fraley question regarding the desired behaviour:

Any thoughts on what the warning message should be?
BrunoQuaresma commentedon Oct 14, 2025
@cian since we do not save chat history or context, how would that work? A continuation prompt would be interpreted by the agent as a brand-new prompt 🤔.
johnstcn commentedon Oct 15, 2025
That's exactly my point -- we would need the agent to support resuming the previous session in order for a 'continuation prompt' to work. We currently leave it up to the workspace to store the chat history and context.

The Claude Code and Copilot module supports resuming... it is just not well documented or enabled in our template...

The scope of this issue isn’t very clear, so I’m moving it to Blocked until we figure this out.
BrunoQuaresma commentedon Oct 15, 2025
As decided on Slack, this will be fixed once modules are enabled to resume the task.

This has been resolved for the claude code module in v3.2.2 only but the other modules will soon follow
coder/registry#496

@DevelopmentCats can you also ensure this is fixed in our dogfood template (i think its version controlled in this repo) and our triage template?
DevelopmentCats commentedon Oct 22, 2025
@bpmct I have a PR open to bump this #20422
Ill make sure its updated in the triage template as well
