tuyaopen/onchip-i2c

tuyaopen/onchip-i2c is a skill for Claude Code from tuya/tuyaopen-ide-manifests. It costs 88 tokens per session (1,175 once invoked), scanned A, original, no licence file.

A guide for using a TuyaOpen device's built-in I2C controller to communicate with sensors and other chips. I2C is a two-wire bus using SCL for the clock and SDA for data, with each device identified by a 7-bit address.

In plain words
What is it for?
Use it to configure SCL and SDA, initialize the bus, and send or receive data from a 7-bit I2C device through the tkli2c API.
Why use it?
It explains the required bus setup and communication steps without requiring manual handling of the low-level API details.

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.

Security

Grade A, and why

tuyaopen/onchip-i2c 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 10d 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
