mmk-threads

The stated purpose and capabilities are broadly aligned: a Threads skill using a Threads-oriented CLI is plausible. The main risk is trust and transparency: this skill depends on an external `mmk` executable with unverifiable provenance from the provided evidence, broad shell permission for any `mmk` subcommand, and hidden auth/data-flow details delegated to another skill. That makes the skill suspicious from a supply-chain and execution-trust perspective even without direct evidence of malicious behavior in this file.
