Changelog

1.0.0 - 2026-06-15

Initial release. Implements the full Claude Code IDE-integration protocol for Visual Studio 2026.

Features

  • Native diff with single-gate accept/reject - Claude's proposed edits open in Visual Studio's diff viewer (not a terminal y/n). A PreToolUse hook intercepts every Edit/Write/MultiEdit and routes it through the diff; the CLI writes the file only after you accept. No duplicate terminal prompt.
  • Reject with feedback - an InfoBar action in the diff that prompts for a reason; the reason is returned to the CLI as permissionDecisionReason so Claude reconsiders.
  • Run wild (auto-accept) - a panel checkbox that allows edits without opening the diff, for unattended sessions. Resets each VS session.
  • Diagnostics sharing - getDiagnostics reads the VS Error List (Roslyn for C#, MSVC toolchain for C++) and returns LSP-shaped diagnostics so Claude can see and fix your build errors.
  • Selection context - a selection_changed notification (150 ms debounce) keeps Claude aware of the active file and highlighted lines in real time.
  • One-click Launch - Tools -> Launch Claude Code opens a terminal pre-wired with ENABLE_IDE_INTEGRATION and the bridge port, working directory set to the solution root. Auto-installs the permission and usage hooks on first launch.
  • Dockable Claude Code panel - connection status pill, accept/reject edit counts, token usage (input / output / cached) and estimated cost (latest call + cumulative session), pending-diff strip, and a curated activity feed. VS-theme-aware (dark/light).
  • Full 12-tool parity - all tools advertised in tools/list: openFile, openDiff, getCurrentSelection, getLatestSelection, getDiagnostics, getOpenEditors, getWorkspaceFolders, checkDocumentDirty, saveDocument, close_tab, closeAllDiffTabs. executeCode returns an honest MCP error (no VS equivalent).
  • RDT-aware write-back - accepting an edit updates an open editor buffer in place (no reload prompt) via IVsRunningDocumentTable.
  • Lockfile lifecycle - stale (dead-PID) lockfiles are reaped on startup; the lockfile is deleted on clean shutdown and on an unexpected server fault.
  • WorkspaceWatcher - keeps the lockfile's workspaceFolders in sync as solutions open/close so /ide always matches the current working directory.

Known limitations

  • Visual Studio 2026 only (VS 2022 backfill planned - see ROADMAP.md).
  • Diagnostic ranges are point ranges (Error List only exposes line/column); Roslyn-precise spans are a future enhancement.
  • The IDE-integration protocol is undocumented and version-fragile. Tested against claude 2.1.173.
  • Token stats refresh on edits (the reliable hook trigger); a chat-only turn may not update them immediately.
  • Cost figures are estimates (hardcoded per-tier list prices), not billing.
