Summary

AI summary

Workflow block and TOON table are no longer emitted for flat single‑action tools, eliminating redundant duplication while preserving metadata.

Full changelog

Fixed

@mcpfusion/core — Redundant Workflow block / TOON table on flat single-action tools

  • The auto-generated Workflow: section (DescriptionGenerator) is no longer emitted for flat tools with a single action (e.g. defineTool({ actions: { default } }), YAML/Bundle server factories). It duplicated the tool summary with no dispatch value. Now emitted only for grouped tools or flat tools with 2+ actions.
  • ToonDescriptionGenerator brought to parity — the TOON action-metadata table follows the same rule.
  • No metadata lost: destructive/readOnly/idempotent hints remain on tool annotations; required params remain in the inputSchema field annotations.

Changed

  • All @mcpfusion/* cross-dependencies updated to ^4.4.1.

Full monorepo bumped 4.4.0 → 4.4.1.
