Manage Obsidian vault operations. Handles markdown formatting, YAML frontmatter, folder organization, internal linking, and vault-specific conventions. Use when creating, updating, or organizing Obsidian notes.
Draft, organize, or update development journal entries. Use when user requests daily journal generation, work review, standup preparation, or asks "what did I work on today/this week?"
Nudge the user with time-based reminders (stopping times, meetings, break suggestions). Surfaces via hook on prompt submission -- requires human interaction to fire. NOT for process monitoring or job polling -- use `sleep` in Bash instead.
(TDD) Use when implementing any feature or bugfix. Apply the Logic Gate to identify what needs tests, then use the Iron Rule for strict test-first development on logic.
