• Model picker and SYSTEM skills support

GitHub MCP Server v0.26.0+ features (docs/src/content/docs/reference/tools.md):

<issue_title>[plan] Update documentation for CLI version changes</issue_title>
<issue_description>## Objective

Update documentation to reflect new features and changes in the updated CLI versions.

Context

Four CLI tools have been updated with new features. Documentation should be updated to help users understand and use these new capabilities.

Approach

1. Review existing documentation for references to CLI versions
2. Add documentation for Copilot CLI 0.0.370 tool permission changes
3. Add documentation for Copilot CLI --plain-diff and --no-auto-update flags
4. Add documentation for Codex 0.74.0 /experimental command
5. Add documentation for GitHub MCP Server feature flags
6. Update any version-specific troubleshooting guides

Files to Update

• docs/ directory - check for CLI references
• README.md - update if it mentions CLI features
• Any workflow examples that demonstrate CLI usage

Acceptance Criteria

• Tool permission flags are documented
• Experimental features are explained
• Feature flag usage is documented
• Examples are updated if needed
• Version numbers are current where mentioned

@copilot do not document engines cli flags

Removed all Copilot CLI flags documentation (--allow-tool, --deny-tool, --available-tools, --excluded-tools, --no-auto-update, --plain-diff) from engines.md. Kept only the Codex features documentation. (fe72c9b)

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: /opt/hostedtoolcache/node/24.12.0/x64/bin/node node /home/REDACTED/work/gh-aw/gh-aw/docs/node_modules/.bin/astro build (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)
