$28

Execute the maintenance cycle:

Step 1: Source freshness check

Compare each source in .manifest.json against its file's modification time. Classify as:

• Fresh — mtime ≤ ingested_at

• Stale — mtime > ingested_at (new content exists, not yet ingested)

• Missing — source file no longer exists

Step 2: Index refresh

Read $OBSIDIAN_VAULT_PATH/index.md. If any pages in the vault are missing from the index (or vice versa), update the index. Use find $OBSIDIAN_VAULT_PATH -name "*.md" -not -path "*/_*" to enumerate vault pages, then reconcile against the index.

Step 3: hot.md update

Read hot.md. If it's >48h old based on its updated: frontmatter, regenerate it: read the 10 most recently modified wiki pages and write a fresh ~500-word semantic snapshot of what the wiki covers. This keeps the next session's context warm without a full vault crawl.

Step 4: Write state

Write to the vault-scoped $STATE_DIR derived in "Before You Start":

date +%s > "$STATE_DIR/.last_update"

echo "<stale_count>" > "$STATE_DIR/.pending_delta"

echo "$OBSIDIAN_VAULT_PATH" > "$STATE_DIR/.vault_path"

Step 5: Spawn impl-validator

After the cycle, spawn impl-validator as a subagent:

impl-validator check:

  goal: "Daily wiki maintenance — index reconciled, hot.md refreshed, state file written"

  artifacts:

    - $OBSIDIAN_VAULT_PATH/index.md

    - $OBSIDIAN_VAULT_PATH/hot.md

    - $STATE_DIR/.last_update

    - $STATE_DIR/.pending_delta

  checks:

    - Does .last_update contain a recent Unix timestamp (within the last 60 seconds)?

    - Does .pending_delta contain a non-negative integer?

    - Does hot.md have an updated: frontmatter field set to today?

    - Does index.md list at least as many pages as exist in the vault?

Apply any FAILs before logging.

Step 6: Log

Append to $OBSIDIAN_VAULT_PATH/log.md:

- [TIMESTAMP] DAILY-UPDATE fresh=N stale=N missing=N index_added=N hot_refreshed=true|false

Step 7: Report to user

## Daily Wiki Update

- Sources: N fresh · N stale · N missing

- Index: N pages (N added, N removed)

- hot.md: refreshed / up to date

Stale sources (run to sync):

  /wiki-history-ingest claude   — N sessions since last ingest

  /wiki-history-ingest codex    — N sessions since last ingest

Setup Mode (triggered by "set up the daily cron" or "install terminal notification")

Walk the user through first-time setup:

Step 1: Verify script exists

Check that $OBSIDIAN_WIKI_REPO/scripts/daily-update.sh exists and is executable. If not, point the user to it.

Step 2: Install launchd plist

# Replace placeholder in plist

sed "s|OBSIDIAN_WIKI_REPO|$OBSIDIAN_WIKI_REPO|g" \

  "$OBSIDIAN_WIKI_REPO/scripts/com.obsidian-wiki.daily-update.plist" \

  > "$HOME/Library/LaunchAgents/com.obsidian-wiki.daily-update.plist"

# Load it

launchctl load "$HOME/Library/LaunchAgents/com.obsidian-wiki.daily-update.plist"

Step 3: Install terminal notification (optional)

Ask the user: "Do you want a terminal reminder when your wiki is stale? (y/n)" — skip this step if they say no, or if the environment is headless/VPS.

If yes, detect the user's shell and target the right rc file:

SHELL_NAME=$(basename "$SHELL")   # zsh, bash, fish, etc.

case "$SHELL_NAME" in

  zsh)  RC_FILE="$HOME/.zshrc" ;;

  bash) RC_FILE="$HOME/.bashrc" ;;

  *)    echo "Shell '$SHELL_NAME' not auto-detected. Add the source line manually to your shell rc file." ; return ;;

esac

Check if wiki-notify.sh is already sourced in that rc file. If not, append:

echo "" >> "$RC_FILE"

echo "# obsidian-wiki terminal notification" >> "$RC_FILE"

echo "source $OBSIDIAN_WIKI_REPO/scripts/wiki-notify.sh" >> "$RC_FILE"

For Fish shell, source syntax is different — provide the manual instruction:

# Add to ~/.config/fish/config.fish:

bass source $OBSIDIAN_WIKI_REPO/scripts/wiki-notify.sh

# (requires bass plugin, or copy the logic natively)

Step 4: Run the script once

bash "$OBSIDIAN_WIKI_REPO/scripts/daily-update.sh"

This initializes $STATE_DIR/.last_update so the terminal notification works immediately.

Step 5: Confirm

Tell the user:

• The cron runs daily at 9 AM (or on next login if missed)

• Terminal notifications appear when the wiki is >20 hours stale

• State is stored in ~/.obsidian-wiki/state/<vault-id>/ — supports multiple vaults independently

• They can run /daily-update anytime to force a sync

• Logs go to /tmp/obsidian-wiki-daily.log

QMD Refresh After Vault Writes

QMD is a search index, not the source of truth. If $QMD_WIKI_COLLECTION is empty or unset, skip this step. Run it only after this skill has written or rewritten vault markdown. If QMD refresh fails, do not roll back the vault changes; report the QMD status separately.

Use $QMD_CLI if set; otherwise use qmd.

${QMD_CLI:-qmd} update

If the output says vectors are needed or embeddings may be stale, run:

${QMD_CLI:-qmd} embed

Verify the collection with either:

${QMD_CLI:-qmd} ls "$QMD_WIKI_COLLECTION"

or, when a specific page path is known:

${QMD_CLI:-qmd} get "qmd://$QMD_WIKI_COLLECTION/<page>.md" -l 5

Record one of:

• QMD refreshed: update + embed + verified

• QMD refreshed: update only + verified

• QMD skipped: QMD_WIKI_COLLECTION unset

• QMD skipped: qmd CLI unavailable

• QMD failed: <short error summary>
