The Morning Brief skill (/morning) exists in the codebase but is currently only enabled in cowork/remote-trigger entrypoints. Regular interactive sessions will see the skill once tengu_morning_brief_skill is enabled more broadly.
- The
eSb()enablement guard evaluates four conditions in sequence: (1) sessions that are neitherCLAUDE_CODE_IS_COWORKnor aremote_cowork/remote_triggerCLAUDE_CODE_ENTRYPOINTare unconditionally disabled; (2)CLAUDE_CODE_ENABLE_MORNING_BRIEF(any truthy value) overrides all other conditions and forces the skill on; (3) remote-cowork and remote-trigger entrypoints returnfalseunless the env-var override fires first — they do not consult the feature flag at all; (4) only non-remote cowork sessions (CLAUDE_CODE_IS_COWORK=1with a non-remote entrypoint) reach thetengu_morning_brief_skillflag check, which defaults tofalse. - Custom skill prompt resolution follows its own three-step chain in
nSb():CLAUDE_CODE_MORNING_BRIEF_PROMPTenv var is checked first (clamped to 500–50 000 characters); for non-remote sessions only,tengu_morning_brief_configfeature flag (a JSON object with askillPromptstring field) is checked second; the built-in prompt is the final fallback. Remote entrypoints always skip the feature-flag config and jump straight to the fallback. - When not enabled, the
/morningcommand is simply absent from the skill registry — no help text or invocation trigger is registered, so users see no trace of it. - The skill's
menuDescriptionis "Your morning brief — run it now, or set it up as a recurring weekday task", and its invocation trigger list includes "morning brief", "daily brief", "set up my morning brief", "what's my day look like", and "run my brief".
Feature-flagged — tengu_morning_brief_skill defaults to false. Can be forced on with CLAUDE_CODE_ENABLE_MORNING_BRIEF=1.
Enablement guard eSb() (lines 839865–839871) — four-path conditional ending with Qe("tengu_morning_brief_skill", !1); prompt resolver nSb() (lines 839878–839887) reads tengu_morning_brief_config.skillPrompt only on non-remote sessions; prompt length bounds tSb = 500 / rSb = 50000 (lines 839971–839972) (search for "tengu_morning_brief_skill")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
