summary: MCP resources/list, resources/read, prompts/list, prompts/get を explicit namespaced Yoi tool operationsとして exposeし、returned content/templatesを untrusted ordinary Tool result dataとして履歴に記録する。Hidden context injection を導入せず、result size/rich content/paginationを boundedに扱う。

role_plan: Orchestrator は acceptance records を commit 後、専用 implementation worktree `.worktree/00001KVHR3WSN-mcp-resources-prompts-tools` を作成し、Coder をその child worktree への narrow write scope で起動する。Coder 実装後、Reviewer が resources/prompts explicit tool operations、ordinary Tool result/history path、hidden context injection absence、untrusted/bounded content handling、pagination/bounds、no list_changed/sampling/elicitation scope creep を確認する。
