Define 9 new commands under `temporal activity` for standalone (top-level) Activity Executions: start, execute, describe, list, count, cancel, terminate, delete, result. Each mirrors the corresponding `temporal workflow` command pattern. Modify `complete` and `fail` to make --workflow-id optional so they work for both workflow-scoped and standalone Activities. Add two new reusable option sets: `activity-execution-reference` (activity-id + run-id) and `activity-start` (full set of start options including timeouts, retry policy, ID policies, search attributes, headers, metadata, and priority). All new commands are marked Experimental. Existing workflow-only commands (pause, unpause, reset, update-options) are unchanged. Co-authored-by: Cursor <cursoragent@cursor.com>
- cancel: Rewrite description following Python SDK style, explaining that cancellation is a request delivered via heartbeat response - complete/fail: Use activity-reference option set instead of inlining activity-id/run-id, fixing missing short flag and missing "latest run" description - fail: Clarify detail vs reason option descriptions (detail is the failure details payload; reason is the failure message) - count/list: Add example queries, improve query option descriptions, add visibility docs links - delete: Add note about async deletion and running activity termination (from proto docs) - execute: Use "output" instead of "printed" - update-options/pause/unpause/reset: Add "Not supported for standalone Activities" sentence - Remove resolved TODO comments Co-authored-by: Cursor <cursoragent@cursor.com>
Phase 2: Run code generation producing command structs for all 9 new commands and 2 new option sets (ActivityReferenceOptions, ActivityStartOptions). Phase 3: Implement run() methods for all new commands: - start: calls StartActivityExecution, outputs activity ID and run ID - execute: calls StartActivityExecution + PollActivityExecution, outputs the activity result - describe: calls DescribeActivityExecution with include_input and include_outcome - list: calls ListActivityExecutions with pagination, table output - count: calls CountActivityExecutions with group support - cancel: calls RequestCancelActivityExecution - terminate: calls TerminateActivityExecution with default reason - delete: calls DeleteActivityExecution - result: calls PollActivityExecution, outputs the activity result Shared helper buildStartActivityRequest() constructs the gRPC request from ActivityStartOptions, handling retry policy, ID policies, search attributes, headers, user metadata, and priority. Shared helper printActivityOutcome() formats activity results for both text and JSON output modes. Also adds description-header to temporal activity docs (required by code generator) and fixes import aliasing (common/v1 -> commonpb). Co-authored-by: Cursor <cursoragent@cursor.com>
Verify all 11 activity subcommands appear in help output (cancel, complete, count, delete, describe, execute, fail, list, result, start, terminate). Verify start command exposes expected flags (activity-id, type, task-queue, timeouts, input). Verify complete and fail commands expose both activity-reference options (activity-id, run-id) and the optional workflow-id flag. Integration tests for the new RPCs are deferred until a standalone-activity-enabled test server is available. Co-authored-by: Cursor <cursoragent@cursor.com>

🤖 The update-options command is implemented and functional. It uses WorkflowService().UpdateActivityOptions() from the gRPC API. You can see the implementation at commands.activity.go:101-236 and the passing tests TestActivityOptionsUpdate_Accept and TestActivityOptionsUpdate_Partial in commands.activity_test.go.
Just ran the tests to confirm:

🤖 Overall Review
This PR adds 8 new temporal activity subcommands (start, execute, describe, list, count, cancel, terminate, result) for standalone activities, and modifies complete/fail to make --workflow-id optional. The structure follows existing workflow command patterns well, and the code is clean and well-organized.
What it's trying to do is right. The mapping of gRPC RPCs to CLI commands mirrors the temporal workflow pattern closely, which is the correct approach.
Issues to address:
-
deletecommand is missing. The plan calls for 9 new commands; only 8 are implemented. The API hasDeleteActivityExecution. Intentional deferral, or oversight? -
Zero-duration timeouts sent for unset flags — see inline comment on
buildStartActivityRequest. -
No tests for modified
complete/fail— These commands changed their option structure. There should be tests for both the standalone path (omitting--workflow-id) and regression tests for the workflow-scoped path. -
Result formatting uses
%v— see inline comment onprintActivityOutcome. -
Unrelated workflow command doc edits — The PR modifies descriptions for
workflow cancel,count,delete,describe,execute,result,start, andterminate. These should be in a separate commit to keep the diff focused. -

🤖 Fixed in 15c1f96. The issue: printActivityOutcome used %v which produces Go's internal format for complex types. Any activity execute or activity result where the activity returns a map will show map[foo:bar] instead of {"foo":"bar"}.
Repro (assuming a running activity that returns a map):
temporal activity execute --activity-id test --type MapReturner --task-queue q --start-to-close-timeout 30s
# Was: Result: map[foo:bar]
# Now: Result: {"foo":"bar"}
The test TestStandaloneActivity_Execute_Success was asserting map[foo:bar]. Fixed in 67942e7 to assert {"foo":"bar"}, then fixed the implementation in 15c1f96 to JSON-marshal the value.

🤖 If the per-RPC rpcCtx deadline fires (e.g. network hiccup causing the 70s timeout), the code falls through to return the error permanently. The parent context (cctx) won't have an error, so the check on line 663 won't save it. Consider retrying on context.DeadlineExceeded when cctx.Err() == nil.

Please compare the sdk-go long-poll loop implementation for update and activity handle.Get(). Does it have the problem your describing?

🤖 sdk-go PollActivityResult (internal_activity_client.go:642) uses the same pattern:
for resp.GetOutcome() == nil {
grpcCtx, cancel := newGRPCContext(ctx, grpcLongPoll(true), grpcTimeout(pollActivityTimeout), ...)
resp, err = w.client.WorkflowService().PollActivityExecution(grpcCtx, request)
cancel()
if err != nil {
return nil, err
}
}And PollWorkflowUpdate (internal_workflow_client.go:2546) does the same with an additional ctx.Err() check after errors.
The CLI's loop is structurally identical. One difference: the CLI checks cctx.Err() (parent context) before returning errors, which correctly distinguishes user cancellation from RPC errors. sdk-go's activity poller returns the raw error without this check. So the CLI's error handling is actually slightly more careful than sdk-go's activity polling.
Neither has the problem I described in my review comment — the per-RPC context timeout is independent of the parent context, and cancel() is called promptly.

…ityExecution) Neither the Go nor Python SDK exposes this RPC, and the server does not support it yet.
The examples were missing the required timeout, which is confusing since either schedule-to-close-timeout or start-to-close-timeout must be provided. Use different timeouts in each example to illustrate both options.
The server returns an empty non-error PollActivityExecution response when the long-poll timeout (default 20s) expires before the activity completes. This is the server's signal to re-issue the poll. Both execute and result were making a single call and treating the nil outcome as a terminal error. Extract shared pollActivityOutcome that loops until an outcome arrives.
Verifies that pollActivityOutcome retries when the server returns an empty PollActivityExecution response (nil outcome), rather than treating it as a terminal error. Uses a gRPC interceptor to simulate the long-poll timeout on the first poll, then return a result on the second. Without the fix in 384741e, this test fails with "activity outcome not available".
- pollActivityOutcome: use `for resp.GetOutcome() == nil` loop matching the SDK-Go's PollActivityResult pattern - printActivityOutcome: use type switch on GetValue() matching SDK-Go style, with informative default case - Enable standalone activities in dev server (history.enableChasm, activity.enableStandalone) with short long-poll timeout (2s) - Rewrite long-poll retry test as proper integration test: activity sleeps 3s, exceeding the 2s long-poll timeout, forcing a retry
…mands Workflow command tests are 100% integration tests (SharedServerSuite), with no TestHelp_* unit tests. Conform to that precedent: - Remove TestHelp_ActivitySubcommands, TestHelp_ActivityStartFlags, TestHelp_ActivityCompleteFlags, TestHelp_ActivityFailFlags - Add integration tests: Start, Execute (success, failure, poll retry), Result, Describe, List, Count, Cancel, Terminate - Add startStandaloneActivity helper for tests that need a running standalone activity

The test was asserting map[foo:bar] which is Go's internal format.
The expected output is JSON: {"foo":"bar"}.
printActivityOutcome now JSON-marshals values so complex types (maps, slices) render as JSON rather than Go's fmt representation.
Tests verify that `activity complete` and `activity fail` work for standalone activities (without --workflow-id, using --run-id).
Replace hand-rolled PollActivityExecution long poll loop with the SDK's client.GetActivityHandle().Get(), which provides proper gRPC long-poll handling and retry semantics. This is analogous to how workflow update uses UpdateWorkflow() + updateHandle.Get().

🤖 Review: Standalone Activity Commands vs Workflow Counterparts
I compared every new standalone activity function and test against its most similar workflow counterpart. The overarching finding is that the workflow implementation uses the Go SDK's high-level client API (cl.ExecuteWorkflow, cl.CancelWorkflow, cl.TerminateWorkflow, cl.ListWorkflow, etc.), while the standalone activity implementation bypasses the SDK almost entirely, going directly to cl.WorkflowService() proto calls for start, describe, list, count, cancel, and terminate. Only getActivityResult (via cl.GetActivityHandle().Get()) uses the SDK.
The Go SDK at this version provides a comprehensive standalone activity API:
cl.ExecuteActivity(ctx, client.StartActivityOptions{...}, activityType, args...)→ActivityHandleActivityHandle.Get(),.Describe(),.Cancel(),.Terminate()cl.ListActivities(ctx, options),cl.CountActivities(ctx, options)
Using the SDK would bring search attribute/header/payload serialization consistency, interceptor support, and reduced maintenance surface — mirroring how workflows are implemented in this CLI.

🤖 Major: hand-rolling proto request instead of using Go SDK
The workflow counterpart uses the SDK: buildStartOptions() builds client.StartWorkflowOptions, then cl.ExecuteWorkflow() handles the proto construction, including search attributes, headers, user metadata, priority, and retry policy serialization.
Here, the entire StartActivityExecutionRequest proto is hand-built (~110 lines). The Go SDK provides client.StartActivityOptions with fields for all of these (ID, TaskQueue, timeouts, policies, RetryPolicy, TypedSearchAttributes, Summary, Details, Priority), and cl.ExecuteActivity(ctx, opts, activityType, args...) returns an ActivityHandle.
Specific issues with the hand-rolled approach:
-
Search attributes (line 157): uses
encodeMapToPayloadsto build rawcommon.SearchAttributes. The workflow version passesmap[string]anyto the SDK'sStartWorkflowOptions.SearchAttributes, letting the SDK serialize. Different code path, potential for subtle differences. -
UserMetadata (line 181): manually creates payloads with
json/plainencoding and%qformatting. The workflow version just setsStaticSummary/StaticDetailsas strings onStartWorkflowOptions, letting the SDK handle serialization. -
Headers (line 169): builds
common.Header{Fields: ...}directly on the proto. The workflow version usescontextWithHeaders()+ SDK interceptor pipeline. Since this call bypasses the SDK, headers won't flow through SDK interceptors.
One consideration: the SDK's ActivityHandle exposes GetID()/GetRunID() but not Started from the proto response. If Started is essential, you could call cl.ExecuteActivity() and always report started=true (since a non-error return implies start), or access it via the raw response if the SDK supports it.
See buildStartOptions in commands.workflow_exec.go:568 and startWorkflow at line 518 for the workflow pattern.

Missing: Type, TaskQueue, and Namespace. The Started field is unique to activities, which is good. But consider also printing the type, task queue, and namespace for parity with the workflow experience.

🤖 Execute: appropriate simplification vs workflow counterpart
The workflow execute (commands.workflow_exec.go:42) is much more elaborate: it shows progress (streaming history events), handles continue-as-new, prints colored status, and has separate JSON/text result formatting.
The activity execute is simpler: start + get result. This is appropriate since standalone activities don't have event history in the same way. The simplicity is good.
However, if the activity fails, the error message "activity failed: " doesn't give the structured output that the workflow version does (e.g. status, failure message, etc.). Consider whether a failed activity should still produce structured output before returning an error, as the workflow version does.

🤖 Result output less informative than workflow counterpart
Compare with the workflow's printTextResult (commands.workflow_exec.go:470) and workflowJSONResult (commands.workflow_exec.go:390):
-
Workflow text output: colored Status (COMPLETED/FAILED/TIMEOUT/CANCELED), RunTime, Result with encoding, and Failure details — all via
cctx.Printer.PrintStructured. -
Activity text output: just
Result: %swith raw JSON bytes. -
Workflow JSON output: rich struct with workflowId, runId, type, namespace, status, closeEvent, result, and optional history.
-
Activity JSON output:
{"result": ...}— minimal.
For consistency with the workflow experience, consider printing a status and using PrintStructured for text output.
Also note: the workflow result commands handle non-completion by returning fmt.Errorf("workflow failed"), reporting both the print error and the status. The activity version returns the error from handle.Get(), which is fine semantically, but the user experience is different.

🤖 Use SDK ActivityHandle.Describe() instead of raw proto
The SDK provides ActivityHandle.Describe(ctx, client.DescribeActivityOptions{}) which returns *client.ActivityExecutionDescription. This is consistent with how workflow describe uses the SDK's typed responses.
The raw proto approach here works, but it bypasses the SDK's response transformation layer (the SDK wraps the proto into ClientActivityExecutionDescription which includes typed search attributes, etc.).

🤖 No JSON output test — compare with TestWorkflow_Execute_SimpleSuccess (commands.workflow_exec_test.go:134)
The workflow execute test checks both text and JSON output:
// JSON
res = s.Execute("workflow", "execute", "-o", "json", ...)
var jsonOut map[string]any
s.NoError(json.Unmarshal(res.Stdout.Bytes(), &jsonOut))
s.Equal("my-id2", jsonOut["workflowId"])
s.Equal("COMPLETED", jsonOut["status"])
s.NotNil(jsonOut["closeEvent"])
s.Equal(map[string]any{"foo": "bar"}, jsonOut["result"])This test only checks text output. Consider adding a JSON variant.
Also, the workflow test verifies the input was received (s.Equal([]any{"val1", "val2"}, s.Worker().DevWorkflowLastInput())). Consider passing input and verifying the activity received it.

🤖 Minimal describe test — compare with workflow describe tests
The workflow describe has extensive test coverage: TestWorkflow_Describe_ActivityFailing, TestWorkflow_Describe_Completed, TestWorkflow_Describe_Versioned, TestWorkflow_Describe_NotDecodable, TestWorkflow_Describe_ResetPoints, etc. (commands.workflow_view_test.go:28+).
This test only checks that ActivityId and type name appear in the output. Consider:
- Testing
--rawflag (the describe command has ac.Rawcode path) - Testing JSON output (
-o json) - Verifying more fields (status, task queue, timeouts)

🤖 No JSON output test — compare with TestWorkflow_Count (commands.workflow_view_test.go:465)
The workflow count test verifies both text and JSON output, including checking the response structure with group values. This test only checks that "Total:" appears in the text output.
Consider adding a JSON variant and potentially testing GROUP BY behavior to match the workflow count test's coverage.

🤖 Cancel/terminate tests don't verify actual state change
Both TestStandaloneActivity_Cancel and TestStandaloneActivity_Terminate check that the command succeeds and prints the expected message, but don't verify the activity's state actually changed.
Compare with how the pre-existing TestActivityPauseUnpause (line 204) uses s.Eventually to confirm the activity is actually paused/unpaused by calling DescribeWorkflowExecution and checking PendingActivities[0].Paused.
For standalone activities, consider verifying via DescribeActivityExecution or handle.Get() that cancel/terminate took effect (e.g. handle.Get() returns a cancellation/termination error).

🤖 Config additions look correct
The three dynamic config settings (frontend.activityAPIsEnabled, history.enableChasm, activity.enableStandalone) are required for standalone activity support. The activity.longPollTimeout of 2s is used by the TestStandaloneActivity_Execute_RetriesOnEmptyPollResponse test which sleeps 3s to force an empty poll.
Minor: the comment // Disable DescribeTaskQueue cache. from the previous line appears to have been displaced — it was likely for the DescribeTaskQueue TTL line below, not for these new config lines.
