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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00022 | $0.00367 |
| Opus 5 | $0.00011 | $0.00183 |
| Sonnet 5 | $0.00004 | $0.00073 |
| Haiku 4.5 | $0.00002 | $0.00037 |
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 8d 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
iMessage Companion Skill
You have access to iMessage tools. Follow this workflow:
First-Time Setup
- Run
im_statusto verify database access and contacts resolution - If Full Disk Access is missing, guide the user to System Settings → Privacy & Security → Full Disk Access
Workflow
- List chats: Use
im_chatsto show recent conversations with contact names - Read messages: Use
im_messageswith a chat ID to read conversation history - Search: Use
im_searchto find messages containing specific text - Participants: Use
im_participantsto see who's in a group chat - Send: Use
im_sendto send a message — always confirm with the user first
Presentation
- Show contact names first, handles in parentheses
- Display messages chronologically
- When paginating, tell the user more messages are available and offer to load them
- For search results, mention how many messages were searched out of the total
Important
- Never send a message without explicit user confirmation
- Chat IDs are the numbers shown by
im_chats(ROWID) - If contacts aren't resolving, suggest checking Contacts permission for the terminal app
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 daveremy/imessage-mcp (2 stars, last pushed 1mo ago), licensed MIT. It adds 22 tokens to every session and 367 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
