Feature flags, all 2,081.

tengu_1p_event_batch_config ◇ Default {}. Batch settings for Claude Code's first-party event logger: scheduledDelayMillis (falls back to OTEL_LOGS_EXPORT_INTERVAL, then 10000), maxExportBatchSize (default 200) and maxQueueSize (default 8192), plus skipAuth, maxAttempts, path and baseUrl passed to the exporter. When the value changes during a session, the logger is flushed and rebuilt with the new settings.never mined ·never mined AND v2.0.37 tengu_account_skills_sync_enabled ◇ Account skills-sync eligibility logic generalized into a reusable descriptorv2.1.234 ○gone AND v2.1.235 tengu_agentview_inherit_mode_demote ◇ A hidden --inherit-permission-mode flag lets a spawned session take its permission mode from whatever launched it.v2.1.257 → v2.1.308 ◆in the build AND v2.1.257 tengu_agile_glade ◇ Usage reports about individual features can now be thinned out or dropped per feature by a server setting, without a new releasev2.1.293 → v2.1.308 ◆in the build AND v2.1.293 tengu_amber_creek ◇ Accepting fullscreen now runs as a trial, and two crashed launches disable it on that machine.v2.1.138 or earlier → v2.1.308 ◆in the build AND v2.1.239 tengu_amber_kestrel ◇ Subagent launching gets a nesting-depth cap, a bypassable concurrency cap, and new teammate/model-inherit rulesv2.1.217 → v2.1.308 ◆in the build AND v2.1.284 tengu_amber_packet ◇ Claude Code can reuse a precomputed conversation summary instead of compacting fresh, gated offv2.1.198 → v2.1.308 ◆in the build AND v2.1.265 tengu_amber_redwood2 ◇ You can now set when auto-compaction kicks in with a new --autocompact flag, and /autocompact works for everyone.v2.1.138 or earlier → v2.1.308 ◆in the build AND v2.1.221 tengu_amber_redwood3 ◇ You can now set when auto-compaction kicks in with a new --autocompact flag, and /autocompact works for everyone.v2.1.154 → v2.1.308 ◆in the build AND v2.1.221 tengu_amber_wren ◇ Default {}. Object of default file reading limits used by the Read tool and other file reads: maxSizeBytes (default 262144), maxTokens (default 25000; CLAUDE_CODE_FILE_READ_MAX_OUTPUT_TOKENS above 0 takes precedence), includeMaxSizeInPrompt (when true, the Read prompt says files larger than the size limit return an error) and targetedRangeNudge (when true, the Read prompt tells the model to read only the part of a file it needs instead of recommending reading the whole file). Numbers that are not positive and finite fall back to the defaults, and the result is cached for the session.v2.1.138 or earlier → v2.1.267 ○gone AND v2.1.75 tengu_artifact_hljs_highlight ◇ Artifact syntax highlighting and mermaid diagrams are now always on; three other gates were renamed and stay off.v2.1.212 → v2.1.238 ○gone AND v2.1.239 tengu_artifact_mermaid_diagrams ◇ Artifact syntax highlighting and mermaid diagrams are now always on; three other gates were renamed and stay off.v2.1.202 → v2.1.238 ○gone AND v2.1.239 tengu_async_goblet ◇ SDK-hosted sessions can now upload attachments, with a clearer message when files stay local.v2.1.234 → v2.1.308 ◆in the build AND v2.1.234 tengu_attempt_decision_shadow ◇ Claude Code now carries new rules for retrying failed API calls, which run alongside the current ones only to compare decisionsv2.1.284 → v2.1.308 ◆in the build AND v2.1.284 tengu_auto_mode_config ◇ Auto-mode permission checks can score risk 0-100 instead of yes/no, but only for configured models.v2.1.138 or earlier → v2.1.308 ◆in the build AND v2.1.307 tengu_auto_mode_worktree_fast_path ◇ Auto mode could stop asking about sibling git worktrees of the same repo, but it is off.v2.1.227 → v2.1.308 ◆in the build AND v2.1.227 tengu_basalt_loom ◇ Plan artifacts now have their own switch instead of riding along with an unrelated experiment.v2.1.223 → v2.1.237 ○gone AND v2.1.223 tengu_bg_binary_takeover ◇ The background daemon can now retire a same-version instance; build is 2.1.248.v2.1.152 → v2.1.308 ◆in the build AND v2.1.248 tengu_bg_leftarrow_inprocess ◇ Backgrounding no longer claims artifact comment monitors will stop; it says they keep auto-replying here.v2.1.138 or earlier → v2.1.308 ◆in the build AND v2.1.296 tengu_bg_low_mem_mb ◇ Low-memory threshold in MiB for background sessions, code default 1024; 0 or less turns the check off. Outside macOS the machine counts as low on memory when the system memory reading is below the threshold; on macOS the value only switches the check on and macOS's critical memory-pressure level decides. While memory is low, the background-session supervisor retires settled workers sooner and before spawning a new session, stops prewarming, keeps no pre-started spare, and a worker that crashes before starting reports possibly low memory.v2.1.138 or earlier → v2.1.308 ◆in the build AND v2.1.232 tengu_bg_prewarm_burst_concurrency ◇ Background session prewarm now checks the concurrency limit instead of the delay value.v2.1.206 → v2.1.308 ◆in the build AND v2.1.248 tengu_bg_prewarm_burst_delay_ms ◇ Default 15000 (milliseconds). How long the background-session supervisor waits, once it is ready, before its prewarm burst: restarting idle background sessions on a stale Claude Code version onto the running one, tengu_bg_prewarm_burst_concurrency (default 3) at a time. The burst is skipped if the supervisor is shutting down, the concurrency is 0 or less, or tengu_bg_attach_upgrade is off.v2.1.206 → v2.1.308 ◆in the build AND v2.1.248 tengu_bg_prewarm_per_sweep ◇ The kite network transport is on by default everywhere, and CLAUDE_CODE_HARBOR_KITE=0 now really turns it off.v2.1.163 → v2.1.308 ◆in the build AND v2.1.248 tengu_bg_worker_ctty ◇ Daemon-mode background workers now try to claim a controlling terminal at startup.v2.1.251 → v2.1.308 ◆in the build AND v2.1.251 tengu_binary_music ◇ Users with a one-million-token context can be offered a choice of when auto-compact kicks in, from 300k to 900k tokensv2.1.300 → v2.1.308 ◆in the build AND v2.1.301 tengu_birch_lantern ◇ Default "off". Picks how /powerup is advertised in a session where the first-run onboarding was shown: "banner" shows an info notice ("New here? Type /powerup for a 5-minute tour..."), "step" adds a "Learn the moves" step after onboarding that can launch the tour, and any other value shows neither. CLAUDE_CODE_POWERUP_ONBOARDING set to banner or step overrides the flag.v2.1.181 → v2.1.308 ◆in the build AND v2.1.181 tengu_bracken_sluice ◇ A read-only subagent that analyses one artifact comment thread exists but stays off.v2.1.227 → v2.1.308 ◆in the build AND v2.1.227 tengu_bramble_lintel ◇ When a pass that saves memories from your conversation stops early, the next pass looks at the same turns againv2.1.138 or earlier → v2.1.308 ◆in the build AND v2.1.305 tengu_brass_condor_loupe ◇ A remote-config gate decides whether an internal UI element shows a summary view or stays hidden.v2.1.257 → v2.1.267 ○gone AND v2.1.257 tengu_breezy_diffie ◇ Handling of repeated 404s while polling a cloud /code-review session is now controlled by a gate, with clearer error messagesv2.1.280 → v2.1.308 ◆in the build AND v2.1.280 tengu_breezy_haven ◇ Claude Code keeps reading input during slow input hooks, and withdraws pending permission requests when you press Stop or the session endsv2.1.295 → v2.1.308 ◆in the build AND v2.1.295 tengu_breezy_pelican ◇ A token limit set to a fraction of the context window, by default one sixth, is built in and stays off unless switched on remotelyv2.1.292 → v2.1.308 ◆in the build AND v2.1.292 tengu_bridge_apply_server_session_config ◇ Remote Control sessions now run in a git worktree whenever the server asks for one, and run in place if the folder is not a git reponever mined ·never mined AND v2.1.281 tengu_bridge_attestation_enforce_config ◇ The switch that turns on device attestation enforcement for the bridge is read through a safer path, and its settings now come from several sourcesv2.1.141 → v2.1.296 ○gone AND v2.1.288 tengu_bridge_child_auto_mode ◇ New unreleased scaffolding tags some spawned bridge sessions as 'rc-child' behind a feature gate, but the other triggers are hardcoded offv2.1.269 → v2.1.308 ◆in the build AND v2.1.281 tengu_bridge_child_auto_over_settings ◇ Bridge-spawned child sessions may be defaulted to auto permission mode, gated offv2.1.271 → v2.1.308 ◆in the build AND v2.1.281 tengu_bridge_child_file_upload ◇ SendUserFile can now deliver files into a project's shared Library folder for bridge child sessionsv2.1.274 → v2.1.308 ◆in the build AND v2.1.274 tengu_bridge_child_machine_settings ◇ Remote Control child sessions gain two new optional capabilities: artifact behavior and inherited machine settingsv2.1.273 → v2.1.308 ◆in the build AND v2.1.281 tengu_bridge_child_tool_diff ◇ New tengu_bridge_child_tool_diff setting controls whether child-session file edits are shown as diffs to a parent sessionv2.1.269 → v2.1.308 ◆in the build AND v2.1.273 tengu_bridge_host_declined_end ◇ Three new remote-bridge switches appear, covering a retry after a rejected token refresh and two unread ones.v2.1.238 → v2.1.308 ◆in the build AND v2.1.238 tengu_bridge_host_profile ◇ A new setting controls how much machine info Remote Control shares when it registers a

tengu_bridge_subagent_frames ◇ A subagent bridge forwards frames by default but raw text forwarding is off.v2.1.251 → v2.1.308 ◆in the build AND v2.1.251 tengu_bridge_subagent_text ◇ Default false. Controls which subagent messages are forwarded to a Remote Control session.
