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 | $0.00245 | $0.01045 |
| Opus 5.5 | $0.00098 | $0.00418 |
| Sonnet 5.5 | $0.00049 | $0.00209 |
| Haiku 4.5 | $0.00024 | $0.00104 |
Grade A, and why
whatsapp-send scanned grade A with 1 finding 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

WhatsApp Send — Messages & Media
ROUTING RULE: NEVER open WhatsApp in Chrome or any browser to send messages. ALWAYS use the MCP tools below. Chrome is a fallback ONLY if MCP tools explicitly error out.
Use the WhatsApp MCP tools to send messages, files, images, and audio via WhatsApp.
Available Tools
send_message(recipient, message)— send a text messagesend_file(recipient, media_path)— send an image, video, or documentsend_audio_message(recipient, media_path)— send audio as a voice message (requires FFmpeg)search_contacts(query)— find a contact's phone number or JID
Pre-Send Checklist
CRITICAL: Always confirm with the user before sending any message. Present:
- The recipient (name and number)
- The exact message text or file to send
- Ask for explicit approval
Workflow
Sending a Text Message
- Identify the recipient — search contacts if needed using
search_contacts. - Compose the message — draft the message based on the user's request.
- Confirm with user — show the recipient and message, ask for approval.
- Send — use
send_messagewith the recipient's phone number (no + prefix, with country code) or JID.
Sending a File
- Identify the recipient and locate the file — ensure the file path is absolute.
- Confirm with user — show recipient and file name.
- Send — use
send_filewith the recipient and absolute file path.
Sending Audio/Voice Message
- Identify the recipient and locate the audio file.
- Confirm with user.
- Send — use
send_audio_message. If it fails due to FFmpeg, fall back tosend_file.
Recipient Format
- Phone number with country code, no + or symbols:
972501234567 - Individual JID:
[email protected] - Group JID:
[email protected]
If the user says "send to Yossi" — first use search_contacts("Yossi") to find the number.
Group Messages
For group chats, the recipient must be the group JID (ending in @g.us). Use list_chats to find group JIDs by name.
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.
