[WIP] Fix documentation bloat in tools reference

[Copilot]

• Analyze comment requesting validation of snippets and environment variables
• Fix incorrect environment variable name (GITHUB_MCP_TOKEN → GH_AW_GITHUB_TOKEN)
• Fix invalid YAML syntax in GitHub tools example
• Validate all code snippets are syntactically correct
• Test build documentation to ensure no errors

💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers. Learn more Copilot coding agent tips in the docs.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• telemetry.astro.build
  • Triggering command: node /home/REDACTED/work/gh-aw/gh-aw/docs/node_modules/.bin/astro build (dns block)
  • Triggering command: node /home/REDACTED/work/gh-aw/gh-aw/docs/node_modules/.bin/astro preview (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
