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 | $0.00022 | $0.00849 |
| Opus 5 | $0.00011 | $0.00425 |
| Sonnet 5 | $0.00004 | $0.00170 |
| Haiku 4.5 | $0.00002 | $0.00085 |
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 6d 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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
iMessage
Use imsg to read and send iMessage/SMS via macOS Messages.app.
Prerequisites
- macOS with Messages.app signed in
- Install:
brew install steipete/tap/imsg - Grant Full Disk Access for terminal (System Settings → Privacy → Full Disk Access)
- Grant Automation permission for Messages.app when prompted
When to Use
- User asks to send an iMessage or text message
- Reading iMessage conversation history
- Checking recent Messages.app chats
- Sending to phone numbers or Apple IDs
- Evaluating iMessage bridge/privacy options for Hermes; see before recommending Photon/Spectrum Cloud
When NOT to Use
- Telegram/Discord/Slack/WhatsApp messages → use the appropriate gateway channel
- Hermes iMessage gateway integration (live bidirectional channel) → that's the BlueBubbles platform adapter in the Hermes gateway. The
imsgCLI here is for one-off scripting, not persistent gateway connections. - Group chat management (adding/removing members) → not supported
- Bulk/mass messaging → always confirm with user first
- Sensitive/private conversations over third-party iMessage cloud bridges unless retention, logging, employee-access, attachment-cache, and training-use guarantees are verified first
Privacy Notes
- Prefer local Mac-backed Messages.app/
imsgworkflows for maximum privacy: content stays on the Mac and uses the user's own Messages account. - Photon/Spectrum iMessage Cloud is a portability bridge, not an end-to-end-private-from-Photon path. Treat it as a trusted third-party message processor unless Photon provides zero-retention/self-hosted guarantees.
- For platform privacy details and due-diligence questions,

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 AtlasOmnia/donna-starter (103 stars, last pushed 6d ago), licensed MIT. It adds 22 tokens to every session and 849 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 2026-08-30.
