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 | $0.00143 | $0.01389 |
| Opus 5.5 | $0.00057 | $0.00556 |
| Sonnet 5.5 | $0.00029 | $0.00278 |
| Haiku 4.5 | $0.00014 | $0.00139 |
Grade A, and why
imessage 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
imessage
Read and send iMessages locally. No MCP server, no cloud API. Two modes with very different permission costs.
Requires a Mac with iMessage set up: Messages must be signed into your Apple ID and able to send from this Mac. macOS only, this does not work on Windows, Linux, or from a phone alone.
When to use
- "Text Alex that I'm running 10 min late"
- "Draft an iMessage to [person] saying..."
- "Send Sam a quick text about..."
- "What did [person] text me yesterday?"
- "Pull up my last thread with [person]"
Do NOT use for:
- Slack or other chat apps (use their own tools)
- Email (use an email tool)
- SMS to non-Apple recipients without confirming the contact has iMessage (AppleScript can still route as SMS via the iPhone bridge, but only if Continuity is on)
Modes
Send mode (default, low-permission)
- Confirm recipient and message. Match the tone to the recipient (casual with friends, more measured with colleagues).
- Show the draft. Wait for "send it" or equivalent.
- On approval, send via AppleScript:
osascript <<'APPLESCRIPT'
tell application "Messages"
set targetService to 1st service whose service type = iMessage
set targetBuddy to buddy "PHONE_OR_APPLE_ID" of targetService
send "MESSAGE_TEXT" to targetBuddy
end tell
APPLESCRIPT
Replace PHONE_OR_APPLE_ID with the recipient's phone (E.164, e.g. +19175551234) or Apple ID email. Replace MESSAGE_TEXT with the drafted body, escaping quotes and backslashes for AppleScript.
Permission required: System Settings, Privacy & Security, Automation, enable Messages under Terminal (or iTerm, or whatever shell host Claude Code runs in).
Permission NOT required: Full Disk Access. Send mode does not read chat.db.
Read mode (opt-in, high-permission)
Required for: pulling thread history, searching past messages, triaging recent texts.
Cost: Reading ~/Library/Messages/chat.db requires Full Disk Access for Terminal. FDA is a broad, system-level permission. Once granted, the terminal binary can read all protected user data (Photos, Health, banking caches, and more), not just iMessages. This is the OS design, not a skill choice.
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.

imessage is a skill published in the GitHub repository nataliacorrea03/claude-code-skills (4 stars, last pushed 3mo ago), licensed MIT. It adds 143 tokens to every session and 1,389 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings.
