notes-export — full local snapshot of Apple Notes

Self-Evolving skill — if export behavior drifts (AE size caps, chunk failures, encoding), fix this SKILL.md and scripts/notes.ts OSA_EXPORT (+ a test in notes-core.test.ts for any pure helper change); see the Post-Execution Reflection at the bottom.

One command captures everything Notes holds into a timestamped local snapshot:

NC="$HOME/.claude/plugins/marketplaces/cc-skills/plugins/notes-commander/scripts/notes.ts"
bun "$NC" export                     # → ~/.local/share/notes-commander/export/<stamp>/
bun "$NC" export --out /path/to/dir  # explicit destination

What a snapshot contains:

• One markdown file per note, under <account>/<folder>/… mirroring the Notes hierarchy. Each file has YAML frontmatter (account, folder, id, modified) and the note body as plain text (decoded via textutil, UTF-8-safe, CJK-safe).
• manifest.json — every folder (with counts) and every note (id, name, modified, relative file path, char count). This is the machine-readable index for audits and diffs.
• Filenames are sanitized (safeFilename) and suffixed with the note's core-data id (.p1234.md), so same-titled notes never collide.

Rules

• Run this before any notes-organize operation — it is the undo story. Notes has no API-level undo; a snapshot does.
• The default root (~/.local/share/notes-commander/export/) is deliberately OUTSIDE any git repo so note content can never be accidentally committed. Don't redirect --out into a repo.
• Snapshots are full (not incremental); each run creates a new timestamped dir. Old snapshots are plain dirs — delete them manually when no longer wanted.
• Recently Deleted is deliberately skipped (restore a note in the Notes UI first if you want it captured).

MemPalace bridge (if mempalace is on PATH)

After a successful export, re-mine the snapshot into the local MemPalace semantic index so the notes are searchable by meaning (multilingual — verified on 中文 content):

command -v mempalace >/dev/null && mempalace mine "<snapshot-dir>" --wing apple-notes --agent terry

Idempotent (unchanged notes are skipped). Recall then works via mempalace search "<query>" --wing apple-notes. Skip silently when mempalace isn't installed — the bridge is an enhancement, not a dependency.

• A large library takes a few minutes (verified live: 400 notes ≈ 2.5 min) — bodies are fetched in chunks of 20 because one giant Apple Event reply blows the AE size cap (-1741). A failed chunk degrades to per-note fetches; a still-failing note becomes a warning + exit code 3 (partial export is LOUD, never silent). Transient -600/-1712 launch races retry automatically.

Post-Execution Reflection

After an export, check: (1) exit code 0 and note count ≈ live inventory total? Exit 3 means some notes were skipped — read the ⚠ lines and investigate before trusting the snapshot as a backup. (2) Spot-check one CJK/emoji-titled file — mojibake means the <meta charset="utf-8"> textutil prefix or safeFilename drifted. (3) New -1741s despite chunking → shrink the chunk size in OSA_EXPORT. Update this SKILL.md only for real, reproducible drift.
