&lt;p&gt;Adopting a new LLM provider for a coding-agent role looks easy from the docs. Read the model card, copy the partner adapter&amp;rsquo;s defaults, ship. A week later you find out the provider rejects &lt;code&gt;tool_choice=required&lt;/code&gt; in thinking mode, the docs lied about &lt;code&gt;reasoning_content&lt;/code&gt; echoing, and your retry loop multiplies the per-turn timeout by 3x because the rate-limit response isn&amp;rsquo;t JSON.&lt;/p&gt;
&lt;p&gt;The docs miss what was patched after release. The community catches what the docs miss. Partner adapters encode lived defaults nobody published. Your own adapter has bugs you can&amp;rsquo;t see from inside it. Reading any one of these in isolation gets you to &amp;ldquo;I think I understand this provider.&amp;rdquo; Reading all five in parallel gets you a knob list, an open-contradictions list, and a list of bugs to fix before the matrix runs. The pattern: spawn 5 parallel research sub-agents, one per angle, then synthesize.&lt;/p&gt;</description></item></channel></rss>
