5.0.0-beta.6

Patch Changes

• #1799 503a929 Thanks @TooTallNate! - Use inline sourcemaps for all workspace packages; published packages no longer ship external .js.map files.

• Updated dependencies [1e6b1fd, 2050656, 62ec537, 503a929]:

  • workflow@5.0.0-beta.8

5.0.0-beta.1

Patch Changes

• #1663 4d31619 Thanks @gr2m! - fix(ai): preserve provider tool identity across step boundaries

  Provider tools (e.g. anthropic.tools.webSearch) were being converted to plain function tools in toolsToModelTools, stripping type: 'provider', id, and args. This caused providers like Anthropic Gateway to not recognize them as provider-executed tools.

• Updated dependencies [c6b630f, 71d39d2, 0a86de3]:
