Thank you for your contribution @XiaofuHuang! We will review the pull request and get back to you soon. |
Adds a `--inspector` flag to `azd ai agent invoke` that launches the Agent Inspector SPA in the browser and proxies localhost HTTP/SSE/RPC to the agent running via `azd ai agent run --local`. The SPA is the same one shipped by the VS Code extension built in `--mode azd`; its assets are checked in under `internal/inspector/assets/` and embedded via `go:embed`. Includes table-driven tests for `assertLocalhost` and a server smoke test that binds an ephemeral port and verifies SPA fallback. Co-Authored-By: Claude Opus 4 <noreply@anthropic.com>

- Drop assertLocalhost and its test; remove dead compile-time check. - Extract validateInspectorFlags; add DefaultInspectorPort constant. - Server.Start signals readiness so browser launches after bind. - sendError uses err.Error() and JSON-RPC -32603; log unhandled methods. - SSE loop uses bufio.Reader.ReadString to avoid per-iteration alloc. - Tests use strconv.Itoa and the ready channel. - Simplify comments throughout.

- rpc.go: handle the new "inspector/fixRequested" SPA notification by logging "there is an error and user want AI to fix (source=...): ..." to the inspector logger. The standalone host has no Copilot UI, so this turns the SPA's Fix buttons into a usable signal during preview. - Re-embed the rebuilt SPA bundle (azd flavor) carrying the matching frontend changes: Fix buttons now route through this notification, and Events/Tools/Output empty states say "Run the agent" instead of "Run the workflow" under VITE_HOST=azd.
handleFixRequested now writes the "user wants AI to fix" line directly to os.Stderr in addition to the regular logger. The root command redirects log.Default() to io.Discard (no --debug) or a daily file (with --debug), so the existing s.logger.Printf was invisible at the terminal. Other inspector logs stay on the existing path — only this specific user-facing signal is teed to stderr.
- rpc.go handleFixRequested: prefix output with "[inspector] [fix-with-ai] ", drop the "(source=...)" tag, and indent continuation lines so multi-line summaries align under the prefix. Empty summaries fall back to "(no error details provided)". - Re-embed the rebuilt SPA bundle (azd flavor) carrying the matching generateFixPrompt change: the "Fix this failed workflow step: <executorId>." prefix line is gone, leaving only the fields that actually carry data (Failed step / Error Code / Error Message / Traceback).
…Default) Drop the URL-based "/responses" gate in proxyInvoke and the hardcoded logRaw=false in proxyFetchSSE. Both now log unconditionally through s.logger; --debug controls visibility through the existing log.Default() routing (file with --debug, io.Discard without). - proxyInvoke: always log POST body and response (full body for /responses, byte count for others to keep diagnostics readable). - proxyInvoke streaming: pass logRaw=true so SSE chunks are logged for every streaming response, not just /responses. - proxyFetchSSE: pass logRaw=true so SPA-driven SSE channels (e.g. /agentdev/v1/diagnostics that powers the Events tab) are also captured. Previously these were silently dropped even with --debug.
proxyInvoke now logs the full buffered response body for every URL, not just /responses. Symmetry with the streaming SSE path which already logs every chunk regardless of endpoint. --debug still controls visibility through log.Default().

This pull request introduces the Agent Inspector UI to the Azure AI Agents extension, allowing users to launch a browser-based inspector for local agents without any Python or Node.js runtime dependencies. The main changes add a new
--inspectormode to theazd ai agent invokecommand, which serves a standalone Single Page Application (SPA) built from the VS Code extension and hosts it with an embedded Go HTTP/WebSocket server. This enables local agent inspection and debugging in a user-friendly way.The most important changes are:
Agent Inspector UI integration:
--inspectorflag (with--inspector-port) to theazd ai agent invokecommand. When enabled (and combined with--local), this launches a browser-based inspector UI connected to the local agent, instead of streaming responses to the terminal. Input validation ensures this flag is only used in supported scenarios. (invoke.go,invoke_inspector.go) [1] [2] [3] [4] [5] [6]rpc_handler.pylogic, supporting the required WebSocket JSON-RPC protocol for the UI. (internal/inspector/assets.go,internal/inspector/proxy_fetch.go) [1] [2]internal/inspector/assets/assets/*,internal/inspector/assets/index.html,build-frontend.ps1) [1] [2] [3] [4]Dependency and build system updates:

internal/inspector/localhost_test.go)Overall, these changes provide a seamless, cross-platform way to inspect and debug local agents via a modern browser UI, improving developer experience and removing the need for extra runtime dependencies.
