Pull request overview

This PR adds comprehensive documentation to CLAUDE.md based on implementation learnings from PR #868, which added SDK version tracking to workflow runs for observability purposes.

Changes:

  • Document the fixed versioning strategy for workflow and @workflow/core packages
  • Add guidance for common patterns: genversion for build-time version injection and turbo caching for generated files
  • Document architecture notes about the executionContext field flexibility and observability data hydration behavior

Reviewed changes

Pull request overview
This PR adds comprehensive documentation to CLAUDE.md based on implementation learnings from PR #868, which added SDK version tracking to workflow runs for observability purposes.
Changes:
  • Document the fixed versioning strategy for workflow and @workflow/core packages
  • Add guidance for common patterns: genversion for build-time version injection and turbo caching for generated files
  • Document architecture notes about the executionContext field flexibility and observability data hydration behavior

Pull request overview
This PR adds comprehensive documentation to CLAUDE.md based on implementation learnings from PR #868, which added SDK version tracking to workflow runs for observability purposes.
Changes:
  • Document the fixed versioning strategy for workflow and @workflow/core packages
  • Add guidance for common patterns: genversion for build-time version injection and turbo caching for generated files
  • Document architecture notes about the executionContext field flexibility and observability data hydration behavior

Pull request overview
This PR adds comprehensive documentation to CLAUDE.md based on implementation learnings from PR #868, which added SDK version tracking to workflow runs for observability purposes.
Changes:
  • Document the fixed versioning strategy for workflow and @workflow/core packages
  • Add guidance for common patterns: genversion for build-time version injection and turbo caching for generated files
  • Document architecture notes about the executionContext field flexibility and observability data hydration behavior

Pull request overview
This PR adds comprehensive documentation to CLAUDE.md based on implementation learnings from PR #868, which added SDK version tracking to workflow runs for observability purposes.
Changes:
  • Document the fixed versioning strategy for workflow and @workflow/core packages
  • Add guidance for common patterns: genversion for build-time version injection and turbo caching for generated files
  • Document architecture notes about the executionContext field flexibility and observability data hydration behavior

Pull request overview
This PR adds comprehensive documentation to CLAUDE.md based on implementation learnings from PR #868, which added SDK version tracking to workflow runs for observability purposes.
Changes:
  • Document the fixed versioning strategy for workflow and @workflow/core packages
  • Add guidance for common patterns: genversion for build-time version injection and turbo caching for generated files
  • Document architecture notes about the executionContext field flexibility and observability data hydration behavior
Reviewed changes

FileDescription
CLAUDE.mdAdds documentation for fixed versioning strategy, common patterns (genversion, turbo caching), and architecture notes (executionContext, observability hydration)
.changeset/config.jsonImplements fixed versioning configuration to ensure workflow and @workflow/core packages maintain the same version

Pull request overview
This PR adds comprehensive documentation to CLAUDE.md based on implementation learnings from PR #868, which added SDK version tracking to workflow runs for observability purposes.
Changes:
  • Document the fixed versioning strategy for workflow and @workflow/core packages
  • Add guidance for common patterns: genversion for build-time version injection and turbo caching for generated files
  • Document architecture notes about the executionContext field flexibility and observability data hydration behavior
Reviewed changes

Pull request overview
This PR adds comprehensive documentation to CLAUDE.md based on implementation learnings from PR #868, which added SDK version tracking to workflow runs for observability purposes.
Changes:
  • Document the fixed versioning strategy for workflow and @workflow/core packages
  • Add guidance for common patterns: genversion for build-time version injection and turbo caching for generated files
  • Document architecture notes about the executionContext field flexibility and observability data hydration behavior
