Daily Update

Runs a full maintenance pass over your Obsidian wiki: checks which sources are stale, reconciles the index with actual vault pages, regenerates hot.md if it's older than 48 hours, and writes state files that power a terminal notification when your wiki falls behind. Comes with launchd setup to run at 9 AM daily. The vault-scoped state directory is smart, supports multiple vaults independently using an MD5 hash of the vault path. Spawns impl-validator as a subagent after each run to verify artifacts before logging. Use it when you say "/daily-update" or "morning sync", or let the cron handle it. The terminal notification piece is optional but ties the whole thing together if you want a gentle nudge when sources drift.

Daily Update — Wiki Maintenance Cycle

You run a lightweight maintenance pass over the wiki: check source freshness, refresh the index, update hot.md, and write the state file that the terminal notification reads.

Before You Start

Resolve config — follow the Config Resolution Protocol in llm-wiki/SKILL.md (inline @name override → walk up CWD for .env → global config → prompt setup). This gives OBSIDIAN_VAULT_PATH and OBSIDIAN_WIKI_REPO.

Derive vault-scoped state dir — all runtime state is scoped to the resolved vault, not global:

VAULT_ID=$(echo "$OBSIDIAN_VAULT_PATH" | md5sum 2>/dev/null | cut -c1-8 || md5 -q - <<< "$OBSIDIAN_VAULT_PATH" | cut -c1-8)
STATE_DIR="$(obsidian_wiki_config_dir)/state/$VAULT_ID"
mkdir -p "$STATE_DIR"
