Inline comments:
In `@examples/workflows/bounded-repair.js`:
- Line 17: Update the result handling around agent() so a null verification
result is checked before accessing result.passed. Preserve the successful return
for passed results, while routing null results through the existing bounded
retry or { passed: false, feedback } fallback behavior.
In `@src/local-agent-acp.ts`:
- Around line 203-205: Update the prompt lifecycle around the updates loop and
session/prompt handling so queued ACP notifications are forwarded to onProgress
while the turn is still active, rather than only after session/prompt completes.
Serialize progress callbacks to preserve notification order and ensure callback
ownership and completion state remain explicit.
In `@src/local-agent-client.ts`:
- Line 331: Update the protocol mismatch error message in the branch guarded by
status.value.activeTurns or status.value.activeWorkflows to tell users to wait
for active turns or workflows, matching the condition that triggers it.
- Around line 407-408: Update the observation classification in request() so
workflow.request operations pause, stop, and stop_agent may use
ensureReadyForObservation(), while resume and restart_agent require the current
executionConfigRevision and current-daemon path. Preserve existing
isObservationRequest handling for other observation requests.
In `@src/local-agent-opencode.ts`:
- Around line 167-169: Update the timeout handling around session.abort and the
cancellation promise so timeout processing awaits cancellation before returning
a retryable error. If cancellation fails, mark execution as uncertain or discard
the runtime instead of allowing a retry while the provider operation remains
active; preserve the existing non-timeout cancellation behavior.
In `@src/local-agent-profiles.ts`:
- Around line 165-168: Update the writeMode parsing logic in the profile
frontmatter parser to inspect the raw writeMode value before readString can
discard non-string types, and throw the existing validation error for booleans,
numbers, objects, and arrays instead of treating them as absent. Preserve
undefined as the absent-field case and retain the current accepted string
values. Add regression tests covering each non-string value.
In `@src/local-agent-runtime.ts`:
- Around line 156-161: Update the environment construction around the provenance
propagation logic to remove all reserved DEVSPACE_WORKFLOW_RUN_ID,
DEVSPACE_WORKFLOW_STEP_ID, and DEVSPACE_WORKFLOW_ATTEMPT_ID keys from the copied
environment before adding current provenance values. Ensure non-workflow
contexts do not inherit stale reserved variables, and add only identifiers
present in provenance while preserving unrelated environment entries.
- Line 122: Enforce cancellation before provider submission while preserving
post-start interruption handling: update the ACP flow around openSession and
session/prompt to recheck after setup; check the signal immediately before
inputQueue.push in the Claude flow; check in Codex runTurn before
request("turn/start") while retaining the existing interrupt check; and throw
before promptOpencodeSession when its external signal is already aborted.
In `@src/server.ts`:
- Around line 492-494: Update the open_workspace text-result formatting to
include each agent profile’s write_mode alongside the fields rendered by
formatVisibleAgent, reusing the existing writeMode-to-write_mode mapping used
when building cardAgents. Ensure text-only MCP clients can distinguish
read_only, allowed, and full_access without changing structuredContent.agents.
In `@src/skills.ts`:
- Around line 101-111: Update the managed skill filtering around managedNames so
"workflows" is included only when config.workflows.enabled is true; preserve the
existing "subagents" filtering and managed workflow insertion behavior, ensuring
disabled workflows retain the user-defined skill and collision diagnostic.
In `@src/workflow-manager.ts`:
- Around line 1049-1052: Update snapshot’s terminal-state artifact handling to
call exportRunArtifacts only when run.resultArtifactId is absent, then reuse the
persisted artifact paths on subsequent observations. Preserve the existing
ARTIFACT_EXPORT_FAILED warning behavior and ensure the result artifact ID
remains persisted through setResultArtifactId.
In `@src/workflow-script.ts`:
- Around line 103-109: Update renameWorkflowMeta to unwrap
ParenthesizedExpression around the metadata initializer before accessing
object-literal properties, matching parseWorkflowScript/decodeLiteral behavior.
Validate the unwrapped initializer as an ObjectLiteralExpression and throw
WorkflowScriptError with WORKFLOW_META_INVALID for invalid metadata instead of
allowing a TypeError.
In `@test/workflow-cli-smoke.test.ts`:
- Line 13: Update the temporary-directory setup in the workflow smoke test to
use the platform-aware tmpdir() value from node:os when constructing the mkdtemp
prefix, while preserving the existing unique devspace-workflow-package- suffix
and realpath handling.

Bound pending progress callbacks.
session/update notifications limit only queue.values. Each progress update still appends a continuation to progressCallbacks. Because onProgress may return a pending promise, faster arrivals can retain an unbounded chain and degrade daemon availability.
Use a bounded queue, or define and apply a safe coalescing policy before scheduling callbacks.

Isolate the registry from user workflow definitions.
WorkflowRegistry.discover() always includes userRoot, which defaults to ~/.devspace/workflows. Host files can add definitions or conflicts to the test's discovery result. They do not change CountingWorkflowRegistry.discoveries, which counts calls, so they cannot by themselves fail the discovery-count delta assertion.
Use a temporary userRoot under root:
-const workflowRegistry = new CountingWorkflowRegistry();
+const workflowRegistry = new CountingWorkflowRegistry({
+ userRoot: join(root, "user-workflows"),

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

There was a problem hiding this comment.
If a completed run’s journal.jsonl is deleted after its artifact ID is stored, terminal get and wait requests only attempt to reuse the old exports. The missing journal produces ARTIFACT_EXPORT_FAILED instead of regenerating artifacts from the durable run records, and the response omits resultArtifact. Large results are returned only as a preview, so callers can no longer retrieve the complete result through the workflow response even though the durable result remains available.
Artifacts
- The authored TypeScript runtime harness creates a terminal large-result workflow, optionally deletes its journal export, and invokes the get and wait service paths; it is the exact executed source.
- Captured output of the intact-export run shows a completed workflow get response with HTTP status not applicable for the direct service call, a resultArtifact reference, a transcript journal, and no warnings; intact exports are returned.
- Captured output of the faulted run deletes journal.jsonl and invokes get plus wait; both successful service responses report ARTIFACT_EXPORT_FAILED and omit the large-result artifact reference, proving no fallback regeneration occurred.
