What is arduino-code-generator?

Project instructions for WhatsApp MCP, a Go server that connects AI assistants to WhatsApp and stores chats and messages in SQLite. They explain how to build, run, format, and clean the project.

Use them when building, running, formatting, or cleaning WhatsApp MCP. They also describe its entry point, shutdown behavior, database storage, and available message-related tools.

They make the required SQLite build settings and startup process clear, including the QR-code pairing step and the need for CGO support.

Token cost

What it costs to keep this loaded

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	$0.00103	$0.01511
Opus 5.5	$0.00041	$0.00604
Sonnet 5.5	$0.00021	$0.00302
Haiku 4.5	$0.00010	$0.00151

Security

Grade B, and why

arduino-code-generator scanned grade B 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/generate_snippet.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

What ships with it

22 files 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.

Changes

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.
