What

One side agent, a second helper that runs alongside the main one, is given example notes to learn from for its learn, tag and explain notes. Those examples now say "The main agent" where they used to say "I", so the side agent describes the main agent's decisions in the third person. For example, "I chose to add prompt caching" became "The main agent chose to add prompt caching".

Why

In practice, notes from this side agent should read as commentary on what the main agent did rather than as the main agent speaking. It appears to tie in with the You should know side-agent plugin.
