What

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.

Details

The eSb() enablement guard evaluates four conditions in sequence: (1) sessions that are neither CLAUDE_CODE_IS_COWORK nor a remote_cowork/remote_trigger CLAUDE_CODE_ENTRYPOINT are 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 return false unless 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=1 with a non-remote entrypoint) reach the tengu_morning_brief_skill flag check, which defaults to false.
Custom skill prompt resolution follows its own three-step chain in nSb(): CLAUDE_CODE_MORNING_BRIEF_PROMPT env var is checked first (clamped to 500–50 000 characters); for non-remote sessions only, tengu_morning_brief_config feature flag (a JSON object with a skillPrompt string 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 /morning command 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 menuDescription is "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".

Status

Feature-flagged — tengu_morning_brief_skill defaults to false. Can be forced on with CLAUDE_CODE_ENABLE_MORNING_BRIEF=1.

Evidence

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")
