Changes Made

copilot-configuration-basics.md

• Monorepo support — Added a new "Monorepo Support" section explaining that customizations (agents, instructions, skills, MCP servers) are now discovered at every directory level from the working directory up to the git root. Includes a concrete tree diagram showing layered configuration in a monorepo.
• Personal skills directory — Added a "Personal Skills Directory" section documenting ~/.agents/skills/ as a cross-project personal skill store, and noting it aligns with the VS Code GHCP4A extension default.
• /clear vs /new distinction — Added a "CLI Session Commands" table explaining that /new backgrounds the current session while /clear abandons it. Both commands accept an optional prompt to seed the new session.
• /undo command — Documented the new /undo command that reverts the last turn including file changes.

understanding-mcp-servers.md

• Organization policy enforcement — Added a new subsection under Best Practices explaining that GitHub organization admins can now enforce a policy on third-party MCP servers for all members, and that Copilot CLI shows a warning when a configured server is blocked by policy.

automating-with-hooks.md

• sessionStart additionalContext — Added a new section documenting that sessionStart hook scripts can write JSON to stdout with an additionalContext field, which is injected into the conversation at session start. Includes an example script.
• Extension hooks merging — Added a new section explaining that hooks from multiple extensions now merge instead of overwriting, enabling layered hook configurations from different sources.

[Copilot]

The example sessionStart hook prints JSON that interpolates git branch names and issue titles directly into a JSON string. Since these values can contain quotes, backslashes, or newlines, the output can become invalid JSON and fail to parse. Consider generating the JSON with a proper JSON encoder (e.g., jq -n --arg ...), or otherwise escaping the interpolated values so the example always produces valid JSON.

	"additionalContext": "Current branch: $(git rev-parse --abbrev-ref HEAD). Open tickets: $(gh issue list --limit 3 --json number,title | jq -r '.[] | \"#\(.number) \(.title)\"' | tr '\n' '; ')"
	}
	EOF
	branch="$(git rev-parse --abbrev-ref HEAD)"
	issues="$(gh issue list --limit 3 --json number,title \
	| jq -r '.[] | "#\(.number) \(.title)"' \
	| tr '\n' '; ')"
	jq -n --arg branch "$branch" --arg issues "$issues" \
	'{additionalContext: ("Current branch: " + $branch + ". Open tickets: " + $issues)}'

Spelling is inconsistent with the rest of this article (which uses American English "behavior"). Consider changing "behaviours" to "behaviors" for consistency.
