fix(office): tell the CEO which agent failed, not "Error: unknown" - #3485
Conversation
…prompts Both agent_error escalation paths rendered the fixed generic string "An agent session has failed. Error: unknown": queueRunPayload dropped OnAgentErrorPayload for the on_agent_error queue_run action, and buildAgentErrorPrompt read RecentErrors, which production never populates even though retry.go's queueCEOAgentError already carried the real error in its payload. Project failed_agent_id/failed_session_id/error onto the queued run payload for both paths, read them in buildPromptContext, and render them in buildAgentErrorPrompt with RecentErrors[0] and "unknown" as fallbacks.

| Filename | Overview |
|---|---|
| apps/backend/internal/workflow/engine/phase2_callbacks.go | Projects typed agent-error metadata into queue-run payloads while retaining workflow-authored override precedence. |
| apps/backend/internal/office/service/scheduler_integration.go | Extracts failed-agent, failed-session, and error fields from agent-error run payloads into prompt context. |
| apps/backend/internal/office/service/prompt_builder.go | Renders detailed CEO escalation prompts with fallback behavior for missing error metadata. |
| apps/backend/internal/office/service/retry.go | Correctly distinguishes the failed agent from the receiving CEO, but does not forward the available failed-session ID. |
| apps/backend/internal/office/service/scheduler_integration_agent_error_test.go | Covers both escalation payload shapes, but the retry-path case does not assert session propagation. |

Thanks for the contribution. I pushed 79f7d31 to preserve failed session IDs in retry escalations, align the payload docs, guard pointer payloads against CEO self-escalation, and sanitize provider error text before it reaches the CEO prompt. |

Tip
PR walkthrough: Open the visual walkthrough
Today: When an agent errors out mid-task, the CEO's escalation prompt always reads "An agent session has failed. Error: unknown" — no matter which agent failed or what actually went wrong.
After this: The prompt names the failed agent and session, and states the real error message, for both escalation paths (the workflow's
on_agent_erroraction and the pre-existing retry-exhaustion path).Who hits this: The CEO agent, every time it's woken to handle an agent failure during work, review, or approval steps — i.e. most agent_error escalations in practice.
Scope: standalone fix, no sibling PRs.
Not here: rendering a human-readable agent name instead of the raw id (the workflow payload doesn't carry one), and surfacing the run id in the prompt (pre-existing, unchanged).
The failed-agent id, session id, and error message were already being generated at the failure site, but got dropped before reaching the CEO: one escalation path never projected them into the queued run's payload, and the prompt builder only read a field (
RecentErrors) that nothing in production ever populates.Important Changes
queueRunPayloadnow projectsfailed_agent_id/failed_session_id/errorfrom the workflow'son_agent_errorpayload (previously silently dropped).buildPromptContext/buildAgentErrorPromptread those fields for both escalation paths, falling back to"unknown"only when nothing is available.agent_profile_idtofailed_agent_id, since the former is unconditionally overwritten with the receiving CEO's own id elsewhere in the pipeline.Validation
go build ./...CGO_ENABLED=1 go test -tags fts5 ./internal/office/service/... ./internal/workflow/engine/...— green, including 7 new tests covering both escalation paths (payload projection, workflow-authored-payload precedence, prompt rendering, and end-to-endbuildPromptContext).make typecheck— clean.make test— green, exceptinternal/worktree, which fails identically on this machine at the pre-rebase merge base (cd7823631) withunsafe worktree path ...: not a directory— a macOS temp-dir quirk unrelated to this change, reproduced in a scratch worktree before ruling it out.make lint— backendgolangci-lint: 0 issues; webeslint: clean; harness/spec/architecture linters: clean (run directly with a Python 3.10+ interpreter, since the machine's defaultpython3is 3.9 and can't parse this repo's type hints — unrelated to the diff).make lint-format— clean.cd apps/web && pnpm run i18n:ratchet— clean.apps/backend, touches noapps/webor Playwright-covered surface.Possible Improvements
Low risk: the agent's raw error text now reaches the CEO's prompt verbatim (previously always
"unknown"), which is a prompt-injection surface — but not a new one, since other fields (ReviewFeedback,CommentBody) are already embedded verbatim in the same prompt builder.Checklist
