<h3 id="overview">Overview</h3>
<p>The title_generation and metadata_generation agents fail with a YAML parsing error when the current layout context contains apostrophes (e.g. "team's expertise" in a component's text content).<br>
The layout context is injected into the agent's prompt as YAML, but values containing apostrophes are not properly escaped/quoted.</p>
<p>Steps to reproduce:<br>
1. Open Canvas editor<br>
2. Add a component with text containing an apostrophe (e.g. "Our team's expertise")<br>
3. Ask the AI to "Generate a title for this page"<br>
4. YAML parsing error</p>
<h3 id="proposed-resolution">Proposed resolution</h3>
<p>Ensure layout context values are properly quoted/escaped when serialized to YAML before being passed to the title and metadata generation agents.</p>
