Hyday Life Log Skill

First time in this conversation? Run Step 0 from hyday-vault-layout to find the vault root. This skill assumes you already know where the user's Hyday folder lives on disk. Resolve it from ~/Library/Application Support/Hyday/settings.json (macOS) or %APPDATA%\Hyday\settings.json (Windows) — journalPath field. Don't guess, and don't ask the user unless the config lookup fails.

Hyday's journal is a per-day Markdown file decorated with five Life Log marks — short inline annotations that turn a free-form daily log into something Hyday can parse for task ranges, thoughts, and highlights.

When this skill applies

A journal entry is a .md file whose filename is a date:

• 2026-05-17.md ← preferred form
• 2026.05.17.md ← also accepted (dot-separated)

Files matching this pattern are auto-typed as journal. Do not set type: "journal" in frontmatter — the filename does it.

Journal files normally live under journal/<year>/<date>.md. See hyday-vault-layout for placement details.
