What problem does it solve? After finishing a feature or merging a branch, project context and architecture documentation in .github/context/ often becomes stale. This Skill keeps those context files synchronized with the actual codebase so documentation never drifts from reality. ## Core Features & Use Cases - Context Synchronization: Updates the .github/context/ files to reflect recent code changes before opening a PR or after merging. - Shared Agent Workflow: Delegates to the single source of truth at .github/agents/update-context.agent.md, which is shared with GitHub Copilot, avoiding duplicated instructions. - Flexible Diff Scope: Accepts an optional branch name or specific files to diff against, defaulting to comparing HEAD against origin/main. - Use Case: You just finished implementing a new checkout service. Before opening your pull request, invoke this Skill to refresh the architecture and context docs so reviewers see accurate documentation. ## Quick Start Ask the assistant to update the context files and sync the docs after your latest code changes, optionally naming a branch to diff against.
