Do not edit files or start subagents.`\n\nThe check is advisory: never wait for it. Start the rebase at once. Its result reaches you as a\nmessage. Start no other subagents.\n\nBefore each step, append `date -u +%T` and the step name to `/fixture/head-77/log.txt`.\nYour final message is one line.\n/fixture/head-77/repo\nerror: No such remote 'origin'\n", "run": 1 }, { "type": "command_execution", "startedAt": "2026-11-13T19:46:50.216Z", "completedAt": "2026-11-13T19:46:50.220Z", "input": "/bin/bash -lc \"date -u '+%T capabilities' >> /fixture/head-77/log.txt\"", "run": 1 }, { "type": "dynamic_tool", "startedAt": "2026-11-13T19:46:52.018Z", "completedAt": "2026-11-13T19:46:52.031Z", "toolName": "t3-code.orchestrator_capabilities", "input": { "search": "claude-haiku-5-5" }, "output": { "parentThreadId": "thread:delegated-task:command%3Amcp%3A77162775-8d82-4886-b3da-4ab3ce9adf11%3Adelegate-task%3A0f483ad4-f944-454e-a793-866193a870fb", "inheritedProviderInstanceId": "codex", "inheritedModel": "gpt-6.1-terra", "inheritedOptions": [ { "id": "reasoningEffort", "value": "xhigh" }, { "id": "serviceTier", "value": "priority" } ], "runtimeMode": "full-access", "interactionMode": "default", "providers": [ { "providerInstanceId": "codex", "driverKind": "codex", "displayName": "Codex", "models": [], "canRunChildTask": true, "canRunCrossProviderChildTask": true, "constraints": [] }, { "providerInstanceId": "claudeAgent", "driverKind": "claudeAgent", "displayName": "Claude", "models": [ { "id": "claude-haiku-5-5", "label": "Claude Haiku 5.5", "options": [ { "id": "effort", "values": [ "low", "medium", "high", "xhigh", "max", "ultrathink" ], "default": "medium" }, { "id": "ultracode", "values": [ false, true ] } ] } ], "canRunChildTask": true, "canRunCrossProviderChildTask": true, "constraints": [] }, { "providerInstanceId": "cursor", "driverKind": "cursor", "displayName": "Cursor", "models": [], "canRunChildTask": false, "canRunCrossProviderChildTask": false, "constraints": [ "Provider instance is disabled." ] }, { "providerInstanceId": "grok", "driverKind": "grok", "displayName": "Grok", "models": [], "runtimeModes": [ "approval-required", "auto", "full-access" ], "canRunChildTask": false, "canRunCrossProviderChildTask": false, "constraints": [ "Provider instance is disabled." ] }, { "providerInstanceId": "opencode", "driverKind": "opencode", "displayName": "OpenCode", "models": [], "canRunChildTask": false, "canRunCrossProviderChildTask": false, "constraints": [ "Provider instance is disabled." ] }, { "providerInstanceId": "antigravity", "driverKind": "antigravity", "displayName": "Antigravity", "models": [], "runtimeModes": [ "approval-required", "auto-accept-edits", "full-access" ], "canRunChildTask": false, "canRunCrossProviderChildTask": false, "constraints": [ "Provider instance is disabled." ] }, { "providerInstanceId": "fx", "driverKind": "fx", "displayName": "fx", "models": [], "runtimeModes": [ "approval-required", "auto" ], "canRunChildTask": false, "canRunCrossProviderChildTask": false, "constraints": [ "Provider instance is disabled." ] }, { "providerInstanceId": "kiro", "driverKind": "kiro", "displayName": "Kiro", "models": [], "runtimeModes": [ "approval-required", "full-access" ], "canRunChildTask": false, "canRunCrossProviderChildTask": false, "constraints": [ "Provider instance is disabled." ] }, { "providerInstanceId": "devReplay", "driverKind": "acpRegistry", "displayName": "Replay (dev)", "models": [], "canRunChildTask": true, "canRunCrossProviderChildTask": true, "constraints": [] }, { "providerInstanceId": "muse", "driverKind": "muse", "displayName": "Muse Code", "models": [], "runtimeModes": [ "approval-required", "full-access" ], "canRunChildTask": false, "canRunCrossProviderChildTask": false, "constraints": [ "Provider instance is disabled." ] }, { "providerInstanceId": "pi", "driverKind": "pi", "displayName": "Pi", "models": [], "runtimeModes": [ "approval-required", "auto-accept-edits", "full-access" ], "canRunChildTask": false, "canRunCrossProviderChildTask": false, "constraints": [ "Provider instance is disabled." ] } ], "features": { "appOwnedSubagents": true, "asyncPolling": true, "cancellation": true, "batchThreadCreation": true, "threadManagement": true, "incrementalThreadRead": true, "scheduledTasks": true, "maxBatchThreads": 20 } }, "run": 1 }, { "type": "command_execution", "startedAt": "2026-11-13T19:46:55.595Z", "completedAt": "2026-11-13T19:46:55.612Z", "input": "/bin/bash -lc \"date -u '+%T delegate check' >> /fixture/head-77/log.txt\"", "run": 1 }, { "type": "dynamic_tool", "startedAt": "2026-11-13T19:46:55.619Z", "completedAt": "2026-11-13T19:46:55.658Z", "toolName": "t3-code.delegate_task", "input": { "target": { "providerInstanceId": "claudeAgent", "model": "claude-haiku-5-5", "options": { "effort": "low" } }, "mode": "async", "task": "Run the shell command `sleep 120 && echo CHECK OK` and reply with its output only.
