* feat(core): task_stop, send_message, and live transcripts for background agents Add two new tools (task_stop, send_message) and a plain-text transcript writer so the parent model can control and observe long-running background subagents. The agent lifecycle is also tightened so every background launch is paired with exactly one terminal task_notification — including under cancellation races and pathological tools that swallow AbortSignal. * feat(core): switch background-agent transcript to ChatRecord JSONL Replaces the plain-text per-agent transcript writer with one that emits the same ChatRecord schema as the main session log. Each background subagent now writes to <projectDir>/subagents/<sessionId>/agent-<id>.jsonl with a .meta.json sidecar; records carry agentId/agentName/agentColor and isSidechain so a single parser can reconstruct the parent session and its subagents as one tree. A new EXTERNAL_MESSAGE event is emitted when send_message injections are drained inside agent-core, so each follow-up message is persisted as a user-role record and the transcript remains a complete view of the run. read_file's auto-allow set is extended to <projectDir>/subagents/ so the model can keep polling the transcript path advertised in the launch response and the completion notification XML. * feat(core): emit full background agent result in task-notification Drop the 2000-char truncation on <result> in emitNotification. The agent output is already a model-generated summary; truncating it strips content the parent agent specifically asked for. The <output-file> path is still included for anyone who wants the structured transcript. * test(cli): add hasUnfinalizedAgents/abortAll to registry mock The nonInteractiveCli test stub was missing two methods that the runtime now calls when draining background agents on shutdown, causing every runNonInteractive test to fail with TypeError. * test(core): use path.join in agent-transcript path helper assertions Hard-coded forward slashes in expected paths failed on Windows where path.join produces backslashes. * fix(core): thread nested agent identity into sidecar metadata * feat(agent): improve background agent launch tool result - Add internal-ID qualifier, anti-duplication clause, and large-file reading strategy to the launch tool-result template, ported from claw-code. - Rename transcript_file to output_file for consistency. - Reference read_file and run_shell_command via ToolNames constants instead of raw strings. * fix(core): rename send_message target field * fix(core): exclude task_stop and send_message from subagents These are parent-side control-plane tools for managing background subagents. Subagents themselves cannot launch background agents (AGENT is already excluded), so they have no agent IDs to manage natively, and exposing the tools only widens the surface for cross-agent interference if an ID leaks via prompt or transcript. * refactor(core): generalize task_stop and send_message framing to "task" Today every BackgroundTaskRegistry entry is a subagent, but the control-plane tools were named and described as agent-only. Generalize so future task kinds (e.g. backgrounded shells, monitors) can share the same registry without a model-facing rename. - task_stop / send_message: descriptions, error messages, and ToolError enum values drop the "agent" framing in favor of "task". - send_message: parameter to -> task_id, matching task_stop for a uniform control-plane contract. - BackgroundTaskRegistry.hasUnfinalizedAgents -> hasUnfinalizedTasks. - agent-transcript: add a TODO at getSubagentSessionDir flagging that <projectDir>/subagents/ is part of the model-facing contract via <output-file>; future kinds should migrate to <projectDir>/tasks/. - Add a test for complete()-after-finalizeCancelled no-op to pin the one-notification-per-task SDK contract through the post-notified re-entry path. |
