MCP: tighten ui.* descriptions, document ## name semantics#5970
Merged
Conversation
…ntics Shared `kPathSemantics` preamble carries the path / `##` / type / status vocabulary; per-tool `desc`s shrink to what each tool itself does. Tool `name` fields become verb-first (`Click UI button`, `List UI entries (full subtree)`, etc.). No behaviour change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Tool descriptions were long per-tool and didn't document the

Test plan
tools/listvia MCP — all 11ui.*tools updated: each desc starts with the shared preamble (##, type set, status values) and carries a short tool-specific sentence; names are verb-first.🤖 Generated with Claude Code
