Negotiate What a Tool Supports When You Connect
An agent and a tool can be joined while each supports a different set of features, and a caller that assumes a feature is present breaks in a way that looks like a crash rather than a mismatch. This skill covers capability negotiation for agent tools: state the features and limits each side supports at connect time, agree on the common set before work starts, fall back cleanly when a feature is missing, and re check the agreement when either side is updated. The agreement is a promise about what may be called, not a guess drawn from a version string.
