Picks the model for the built-in Explore agent: when false it uses haiku; when true it uses inherit (the parent's model), except on the first-party API when the parent model name contains none of haiku, sonnet or opus, where it uses opus.v2.1.152 → v2.1.197 ○gone never read tengu_quartz_pipit ◇ Default true. When a main-thread turn under an active /goal ends in a way Claude Code classifies as unrecoverable (a context limit such as prompt_too_long or blocking_limit), the goal is cleared, its Stop hook removed, and the warning Goal cleared after an unrecoverable error (...) is shown.

Supplies the background daemon cold-start mode when neither CLAUDE_CODE_DAEMON_COLD_START (transient or ask) nor the daemonColdStart setting is set: true gives ask, false gives transient. With ask, when no background daemon is running and the install prompt has not been dismissed, Claude Code (under further conditions) returns an install request telling you to run claude daemon install instead of spawning a transient daemon.v2.1.138 or earlier → v2.1.308 ◆in the build AND v2.1.120 tengu_quiet_heron ◇ Continuing a server-side conversation thread can now skip resending the system prompt and tools list, with a fallback if the server disagreesv2.1.269 → v2.1.308 ◆in the build AND v2.1.269 tengu_quiet_hollow ◇ No description from anybody.never mined ·never mined never read tengu_quiet_hopcroft ◇ When a hook cannot check a call, Claude Code now blocks the call instead of letting it throughnever mined ·never mined AND v2.1.288 tengu_quiet_lantern ◇ A new gate, tengu_quiet_lantern, controls whether the server classifier falls back to local when unsupportedv2.1.278 → v2.1.308 ◆in the build AND v2.1.278 tengu_quiet_larkspur ◇ Some allowed shell commands followed by a NAME=value argument no longer fail the permission check as an unsafe variable settingv2.1.285 → v2.1.308 ◆in the build AND v2.1.307 tengu_quiet_locket ◇ Behind a server-side switch, cloud sessions take your deny and ask rules from your own settings and keep allow rules only if both sides have themnever mined ·never mined AND v2.1.288 tengu_quiet_slate_wren ◇ Default false.

Read only when CLAUDE_CODE_REMOTE is set, and latched for the rest of the process on first read. In remote sessions with the flag off, reactive compaction after a context-limit error and precomputed compaction are disabled, and proactive auto-compaction is no longer held back for reactive handling or routed through it. Outside remote sessions the flag is not consulted and these paths behave as if it were on.v2.1.172 → v2.1.308 ◆in the build AND v2.1.308 tengu_reactive_compact_succeeded ◇ Compaction telemetry now records the split kind and head truncations, and flags when the whole conversation was summarized.never mined ·never mined never read tengu_reactive_quilt ◇ Cloud sessions gain a way to hand answered file writes to the next worker and place them in the home folder, off unless switched on remotelyv2.1.288 → v2.1.308 ◆in the build AND v2.1.288 tengu_reactive_zephyr ◇ In served sessions, Claude can no longer edit settings files, and permission prompts for network paths are never approved automaticallynever mined ·never mined AND v2.1.288 tengu_read_dedup_killswitch ◇ The Read tool accepts allow_large, letting Claude read an oversized text file in one go when there is still room in the conversationv2.1.138 or earlier → v2.1.308 ◆in the build AND v2.1.296 tengu_record_created_pr_to_ccr ◇ Pull requests you create could be reported to a cloud endpoint, but nothing is sent here.v2.1.234 → v2.1.308 ◆in the build AND v2.1.234 tengu_recursive_lobster ◇ Claude Code registers a new remote switch whose purpose is not yet visiblev2.1.307 → v2.1.308 ◆in the build AND v2.1.307 tengu_reduce_motion_setting_changed ◇ An analytics event, not a feature flag. Claude Code logs it when the Reduce motion toggle in the settings list is changed, with the field enabled; the change also writes the prefersReducedMotion setting.never mined ·never mined never read tengu_reflective_bee ◇ A new dialog can offer to connect GitHub to claude.ai after a git push, not yet confirmed livev2.1.267 → v2.1.308 ◆in the build AND v2.1.308 tengu_reflective_wolf ◇ A new gated mechanism lets Claude Code tell the model when an 'advisor tool' becomes available or unavailablev2.1.268 → v2.1.308 ◆in the build AND v2.1.265 tengu_refusal_fallback_preference_prompt ◇ Switching to a fallback model after a refusal can now ask you first, and remembers your answernever mined ·never mined never read tengu_refusal_fallback_resume_latch ◇ Safeguard and refusal notices now end with a Details line naming the refusal category.never mined ·never mined never read tengu_refusal_fallback_route_declined ◇ A new bypass lets Claude Code re-offer a fallback model for bio-related refusals even after the user already declined that routenever mined ·never mined never read tengu_refusal_fallback_setting_changed ◇ The setting that switches models on a flagged refusal now records when you change it.never mined ·never mined never read tengu_refusal_fallback_suppressed ◇ A new bypass lets Claude Code re-offer a fallback model for bio-related refusals even after the user already declined that routenever mined ·never mined never read tengu_refusal_fallback_triggered ◇ If compaction's model is refused, it retries on an allowed fallback instead of failing outright.never mined ·never mined never read tengu_refusal_same_model_retry ◇ Claude Code now recovers gracefully when a safety filter cuts off a response mid-tool-callnever mined ·never mined never read tengu_reinit_pending_redelivery ◇ SDK hook swaps no longer leave tool calls hanging; stuck ones now ask you to retry.never mined ·never mined never read tengu_relay_chain_v1 ◇ Default false. When true, the Bash tool prompt drops its "When issuing multiple commands:" section (run independent commands as parallel tool calls, chain dependent ones with &&, use ; only when failures don't matter, no newlines between commands).v2.1.138 or earlier → v2.1.197 ○gone never read tengu_relpath_gh7k ◇ No description from anybody.never mined ·never mined never read tengu_remote_agent_permission_fallback ◇ Cloud agents now ask for tool permission in your terminal, marked as remote, with no "always allow" option.never mined ·never mined never read tengu_remote_agent_permission_forwarded ◇ Cloud agents now ask for tool permission in your terminal, marked as remote, with no "always allow" option.never mined ·never mined never read tengu_remote_attach_session ◇ Analytics ids are now filtered to safe characters before being sent, with no change you'll see.never mined ·never mined never read tengu_remote_attach_session_rejected ◇ Attaching to a cloud session with an unknown or malformed id is refused immediately with a message.never mined ·never mined never read tengu_remote_auto_mode_include_destructive_mcp ◇ Destructive MCP tools could stop skipping permission prompts in remote auto mode, but that is off.v2.1.222 → v2.1.308 ◆in the build AND v2.1.259 tengu_remote_autocompact_state_adopted ◇ Remote sessions now use the host's auto-compact settings for context and token display.never mined ·never mined never read tengu_remote_backend ◇ Joining an existing cloud session, trusted-device enrollment and the folder sync offer can now be turned on by two new remote switches, off by defaultv2.1.138 or earlier → v2.1.308 ◆in the build AND v2.1.305 tengu_remote_create_permission_mode_push ◇ A cloud session's starting permission mode is retried, and falls back to default with a warning.never mined ·never mined never read tengu_remote_create_session ◇ Create a cloud session straight from the command line with --environment and a prompt, optionally as JSON.never mined ·never mined never read tengu_remote_create_session_error ◇ Create a cloud session straight from the command line with --environment and a prompt, optionally as JSON.never mined ·never mined never read tengu_remote_create_session_success ◇ Create a cloud session straight from the command line with --environment and a prompt, optionally as JSON.never mined ·never mined never read tengu_remote_headless_client_ ◇ A full headless client for driving cloud sessions over stream-json is in the bundle.never mined ·never mined never read tengu_remote_headless_client_host_dialog ◇ Dialogs shown by your editor now fall back to a safe default when anything goes wrong.never mined ·never mined never read tengu_remote_headless_client_host_request ◇ Fixed a bug where the remote headless client's request logger recorded the wrong outcome valuenever mined ·never mined never read tengu_remote_headless_laptop_linked ◇ Cloud file-sync status now states why sync is off instead of just showing off.never mined ·never mined never read tengu_remote_model_gate_hint ◇ Starting an interactive cloud session now picks a model and permission mode for you, announcing changes.never mined ·never mined never read tengu_remote_notification_routed ◇ Notifications sent from a remote session now actually reach you instead of being silently discarded.never mined ·never mined never read tengu_remote_passthrough_published ◇ New pipeline decides whether MCP tools are 'adopted' as passthrough toolsnever mined ·never mined never read tengu_remote_permission_mode_adopted ◇ If your command-line prompt never reached a cloud session, you now get told to send it again.never mined ·never mined never read tengu_remote_settings_fetch ◇ Remote managed-settings fetches now log detailed telemetry and a clear outcome for every attemptnever mined ·never mined never read tengu_remote_setup_result ◇ An outdated GitHub CLI no longer looks like a missing or signed-out one.never mined ·never mined never read
