What's New

Newer tag v0.46.0 ships rtk 'find' grammar dispatch and output compression, unrelated to the mcp/v3.0.0 SDK release.

Breaking Changes

  • The version sequence moves backwards (mcp/v3.0.0 to v0.46.0), indicating a separate release track rather than an in-place upgrade of the same component.

New Features

  • The find command now dispatches on find's own grammar instead of a generic path.
  • Find output is compressed for predicates the model does not handle, reducing token usage.
  • A tee tail hint is emitted when rtk itself imposes the result cap, so truncation is visible.

Improvements

  • Long recovery-file slugs are hashed to avoid collisions and shorten hints.
  • A never-worse guard plus recovery hint was added to the find rewrite path.
  • CI/CD no longer deletes the tracked scripts/benchmark harness during benchmark runs.

Bug Fixes

  • Git no longer misreads a value-taking option's argument as a patch flag.
  • Patch output from git log commands is now preserved.
  • Process output is decoded using the Windows console code page, fixing garbled text.
  • Discovered paths now have drive letters sanitized correctly on Windows.
  • Rewrite tests accept both Ask and Allow verdicts, removing a flaky failure.

Upgrade Notes

These notes describe a different component (rtk CLI) than the older mcp/v3.0.0 SDK release, so treat this as a track switch rather than a normal bump and verify which artifact your pin actually resolves to. No migration or config changes are documented; the find-command behavior changes are additive and should be safe for existing invocations. If you depend on the eleven-language MCP SDKs, stay on the mcp/v3.0.0 line.
