Release notes: 2026-05-25 — studio-mcp-tool-contracts

Status: Ready for review
Repo: li-langverse/lic
Branch: feat/studio-gap-close-wave1
PH / REQ: PH-AGENT, AGENT-0
Author: agent

Summary (one sentence)

PH-AGENT scaffold: five Studio MCP tool IDs/names, StudioAgentToolRequest on agent chrome, li_rt name table, and smoke round-trip — contracts only, no lis MCP server.

Agent continuation (required)

  1. Read: docs/game-dev/studio-mcp-tools.md, docs/game-dev/world-studio-vision.md §18, packages/li-studio/src/lib.li (PH-AGENT block).
  2. Run: lic check packages/li-studio/src/lib.li; lic check packages/li-studio/li-tests/smoke/studio_mcp_tools.li.
  3. Then: AGENT-1 — register tools in lis mcp li-engine and wire @cursor/sdk per specs/studio-cursor-sdk-rfc.md.
  4. Blocked on: MCP HTTP transport — none for contract merge.

Changed (specific)

Area What Evidence
packages/li-studio studio_mcp_* IDs, studio_mcp_tool_name / from_name, StudioAgentToolRequest, studio_compose_agent_chrome_with_tool; li_std_studio_version → 5 li-tests/smoke/studio_mcp_tools.li
runtime/li_rt.c li_rt_studio_mcp_tool_name, li_rt_studio_mcp_tool_from_name name round-trip in smoke
compiler/codegen/emit.cpp Declare new li_rt symbols link with studio package
docs/game-dev/studio-mcp-tools.md Tool table + proof gate note agent-readable contract

Not changed (scope fence)

  • lis MCP HTTP server — not implemented.
  • @cursor/sdk session wiring — not in this PR.
  • Extra vision tools (am_export_print, chem_dft_run, studio_adaptive_layout) — not in wave-1 ID table.
  • LLVM / httpd / tier5 — not touched.

Breaking / Security / Performance / Downstream

  • Breaking: li_std_studio_version bumped to 5; smokes requiring version 4 must update.
  • Security: N/A — stub IDs only, no network surface.
  • Performance: N/A — O(1) lookup table.
  • Downstream: MCP server agents should use documented tool names before AGENT-1 registration.
