Jordan Ritter fbdaa75d65 docs(vscode-extension): correct RELEASING.md to reflect metadata-sync automation
The aimock-parity paragraph and the Rollback section still described
contributors hand-editing both package.json and CHANGELOG.md. That was
stale — the vscode-extension-changelog-sync.yml workflow auto-syncs
package.json.version (and optionally package.json.description) from
the CHANGELOG entry (and README first paragraph) when the PR is opened
and commits 'chore: release vX.Y.Z' on the PR branch.

Rewrite both passages so the documented flow matches reality: contributor
edits CHANGELOG.md only (optionally README.md), sync workflow handles the
package.json bump automatically, publish workflow self-gates via vsce show
and ships on merge to main.

CopilotKit for VS Code

Preview generative-UI components, explore CopilotKit hooks, and inspect AG-UI agent runs — all without leaving your editor.

Features

The extension adds a CopilotKit container to the activity bar with three panels:

A2UI Catalog Preview

Live-preview A2UI catalog components from your workspace. Pick a component and a fixture, and see it rendered with hot-reload on edits. Fixture files (*.fixture.*) are validated in-editor against the component's registered schema, with diagnostics reported inline.

Hook Explorer (Generative UI)

Scans your workspace for useCopilotAction, useCoAgent, and related CopilotKit hooks, then renders each hook's generative UI — including in-progress and completed states — so you can iterate on agent UIs without running the full agent loop. Jump-to-source and copy-identity actions are available from the sidebar.

AG-UI Inspector

Attach to any AG-UI-compliant agent stream (e.g. a local CopilotKit runtime) and inspect the event timeline in real time: tool calls, message deltas, state patches, and lifecycle events — with payload drill-down for each event.

Requirements

  • VS Code 1.85.0 or newer
  • A workspace containing CopilotKit components, hooks, or an AG-UI runtime to inspect

Install

Install from the Visual Studio Marketplace, or search for "CopilotKit" from the Extensions view inside VS Code.
