Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

c-notes scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

This skill manages Apple Notes via memo and Apple Reminders via remindctl.

Apple Notes — memo

memo list                          # List all notes
memo list --folder "Work"          # List notes in a folder
memo search "query"                # Search notes by content or title
memo read "Note Title"             # Read a specific note
memo create "Title" "Body text"    # Create a new note
memo create --folder "Work" "Title" "Body"
memo delete "Note Title"           # Delete a note
memo folders                       # List all folders

Apple Reminders — remindctl

remindctl list                     # List all reminders
remindctl list "List Name"         # List reminders in a specific list
remindctl add "Task" --due "tomorrow 9am"
remindctl add "Task" --list "Work" --due "2026-03-01"
remindctl complete "Task name"     # Mark reminder as complete
remindctl delete "Task name"       # Delete a reminder
remindctl lists                    # Show all reminder lists

Usage Guidelines

  • Use memo search before creating to avoid duplicates.
  • Dates for remindctl --due accept natural language ("tomorrow", "next Monday") and ISO format.
  • If memo or remindctl is not found, inform the user and suggest installing the OpenPaw c-notes skill.
  • Notes are stored locally in Apple Notes app — no external API needed.

Notes

  • memo requires macOS and Apple Notes app.
  • remindctl requires macOS and Apple Reminders app.
  • Both tools operate on the local user account.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
