Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00106 | $0.01353 |
| Opus 5.5 | $0.00042 | $0.00541 |
| Sonnet 5.5 | $0.00021 | $0.00271 |
| Haiku 4.5 | $0.00011 | $0.00135 |
Grade A, and why
macos-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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
macOS Notes
Manage Apple Notes via $SKILL_DIR/scripts/notes.sh. Notes content is stored as HTML internally; the script accepts plain text or HTML body and returns plaintext when reading.
Quick start
List folders
Always list folders first to discover accounts and folder names:
"$SKILL_DIR/scripts/notes.sh" list-folders
Output format: account → folder (one per line).
Create a note
echo '<json>' | "$SKILL_DIR/scripts/notes.sh" create-note
JSON fields:
| Field | Required | Default | Description |
|---|---|---|---|
title |
yes | - | Note title (becomes the first line / heading) |
body |
no | "" | Note content (plain text — converted to HTML automatically) |
html |
no | "" | Raw HTML body (overrides body if both provided) |
folder |
no | default folder | Folder name (from list-folders) |
account |
no | default account | Account name (from list-folders) |
Read a note
echo '<json>' | "$SKILL_DIR/scripts/notes.sh" read-note
JSON fields:
| Field | Required | Default | Description |
|---|---|---|---|
name |
yes | - | Note title (exact match) |
folder |
no | all folders | Folder to search in |
account |
no | default account | Account to search in |
List notes
echo '<json>' | "$SKILL_DIR/scripts/notes.sh" list-notes
JSON fields:
| Field | Required | Default | Description |
|---|---|---|---|
folder |
no | default folder | Folder name |
account |
no | default account | Account name |
limit |
no | 20 | Max notes to return |
Search notes
echo '<json>' | "$SKILL_DIR/scripts/notes.sh" search-notes
JSON fields:
| Field | Required | Default | Description |
|---|---|---|---|
query |
yes | - | Text to search for in note titles |
account |
no | default account | Account to search in |
limit |
no | 10 | Max results to return |
Interpreting natural language
Map user requests to commands:
| User says | Command | Key fields |
|---|---|---|
| "Note this down: ..." | create-note |
title, body |
| "Save meeting notes" | create-note |
title: "Meeting notes — <date>", body |
| "What did I write about X?" | search-notes |
query: "X" |
| "Show my notes" | list-notes |
(defaults) |
| "Read my note about X" | read-note |
name: "X" |
| "Save this in my work notes" | create-note |
Match closest account/folder from list-folders |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

macos-notes is a skill published in the GitHub repository lucaperret/agent-skills (7 stars, last pushed 7mo ago), licensed MIT.
