[github-actions]

Slide Deck Updates

This PR updates the slide deck at docs/slides/index.md to align with current documentation standards and fix outdated configuration syntax.

Changes Made

1. Fixed cache-memory configuration (line 299)

   • Changed from: cache-memory: true at root level
   • Changed to: tools: { cache-memory: } in tools section
   • Reason: Configuration syntax has changed; cache-memory is now part of the tools section per [tools.md]((redacted)

2. Updated MCP Servers Configuration slide (lines 241-254)

   • Added GitHub MCP toolsets example: tools: { github: { toolsets: [default] } }
   • Reorganized to show recommended toolsets approach first
   • Removed outdated managed endpoint reference
   • Reason: Toolsets are the recommended approach per [tools.md]((redacted)

Layout Issues Fixed

None detected (unable to verify with Playwright due to build permission issues, but changes are minimal and maintain existing structure).
