     Yes, in this session:

     - ponytail: active automatically at full level.
     - i-have-adhd: active automatically and marked always-on.
     - humanizer: active automatically.

     They are not being invoked as tool calls each session. Their instructions were injected into the session
     context by the OpenCode configuration or session setup.

     The separate skill tool is only needed when loading a skill listed under available_skills; these three are
     already active before any tool call.
