Koan Protocol

This skill appears to be what it says: a client SDK for registering an agent and exchanging encrypted messages via koanmesh.com. Before installing or running it, consider the following: (1) it will create and persist cryptographic keys and chat logs under ~/.koan — on Linux these private keys are stored unencrypted by default (the README/SKILL.md warn this); if you will use real secrets, move keys to your OS keychain or an encrypted vault first; (2) the SDK executes platform tools (PowerShell on Windows, macOS 'security') to protect keys where available — subprocesses will inherit environment variables, so avoid running this in an environment with sensitive env secrets you do not trust; (3) network traffic goes to koanmesh.com (registration, message relay, abuse reports) — only proceed if you trust that service and have reviewed its privacy/safety docs; (4) Python requires the public 'cryptography' package; install it in an isolated environment if you want to limit exposure; (5) if you need higher assurance, review the SDK source yourself or run it in an isolated/test agent account and avoid using production credentials until you are satisfied. Overall the package is internally consistent, but it requires trust in the koanmesh service and careful handling of local private keys.
