A is the one account this site reads, N the anonymous baseline, D what the release compiled in. 1,158 of 2,095 gates have been read at all: a run only records the gates its own release wrote about. Claude Code evaluates its gates on Anthropic's servers, so a reading of off can be a rollout this account sits outside of, and none of it says anything about your install. How to read these.

Feature flagWhat it doesSpan v2.1.138 → v2.1.309 Status Reading
tengu_amber_flint ◇ Default true. A kill switch for agent teams: teams are enabled only when CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS is set or --agent-teams is passed, and this flag is on. Turning it off disables teams even when they were requested.v2.1.138 or earlier → v2.1.309 ◆in the build AND v2.1.33 tengu_amber_sentinel ◇ Default false. Gates the Monitor tool, which streams each output line of a background command to Claude as a notification; the tool is enabled only when this flag and a second runtime check both pass. When on, monitors declared by plugins are also started, the Bash and scheduled-task tool instructions point Claude at Monitor for waiting on a condition, and a Bash command with a long leading sleep is blocked.v2.1.138 or earlier → v2.1.309 ◆in the build AND v2.1.98 tengu_ashen_kelp ◇ No description from anybody.v2.1.138 or earlier → v2.1.140 ○gone AND v2.1.132 tengu_bridge_repl_v2 ◇ No description from anybody.never mined ·never mined AND v2.1.77 tengu_cobalt_compass ◇ No description from anybody.never mined ·never mined AND v2.1.75 tengu_cobalt_plinth ◇ PR review artifact pages can show a pinned button that approves the pull request from your GitHub account.v2.1.172 → v2.1.309 ◆in the build AND v2.1.260 tengu_cobalt_raccoon ◇ No description from anybody.v2.1.138 or earlier → v2.1.152 ○gone AND v2.1.105 tengu_code_diff_cli ◇ No description from anybody.never mined ·never mined AND v2.1.50 tengu_collage_kaleidoscope ◇ No description from anybody.never mined ·never mined AND v2.1.73 tengu_harbor_permissions ◇ Default false. Turns on relaying permission prompts to channels: the interactive session registers a channel permission handler, and a tool permission prompt is sent as a notifications/claude/channel/permission_request (tool name, description, input preview) to each connected channel server from the session's --channels list that has registered for it. Tools that require user interaction are not relayed.v2.1.138 or earlier → v2.1.309 ◆in the build AND v2.1.81 tengu_jazzy_bird ◇ A gate that would skip commit and PR attribution text and suppress bridge conflict recovery defaults to off.v2.1.257 → v2.1.258 ○gone AND v2.1.257 tengu_kairos_input_needed_push ◇ Default false. Shows the Push when actions required toggle (the inputNeededNotifEnabled setting) in the settings list and the matching row in the Notifications panel; both places also need a further condition to hold.v2.1.138 or earlier → v2.1.309 ◆in the build AND v2.1.110 tengu_log_datadog_events ◇ Default false. When on, each analytics event that passes sampling is also sent to Datadog, in addition to the first-party event logger; Datadog only accepts it with the first-party API provider and for event names on a built-in list. A datadog: true entry in the remote sink-disable config turns it off regardless.v2.1.138 or earlier → v2.1.309 ◆in the build AND v2.0.36 tengu_marble_whisper ◇ No description from anybody.never mined ·never mined AND v2.1.70 tengu_penguins_enabled ◇ No description from anybody.never mined ·never mined AND v2.1.36 tengu_print_engine_loop ◇ The env var controlling print and engine loop behavior was renamed to CLAUDE_CODE_HUMBLE_HAMMOCK and still defaults to off.v2.1.247 → v2.1.252 ○gone AND v2.1.257 tengu_slate_ribbon ◇ No description from anybody.never mined ·never mined AND v2.1.110 tengu_sotto_voce ◇ No description from anybody.never mined ·never mined AND v2.1.66 tengu_sub_nomdrep_q7k ◇ No description from anybody.never mined ·never mined AND v2.1.91 tengu_worktree_mode ◇ No description from anybody.never mined ·never mined AND v2.1.51
