Release notes: 2026-05-25 — vertical-gap-mcp-chem

Status: Ready for review
Repo: li-langverse/lic
Branch: feat/vertical-gap-mcp-chem
PH / REQ: PH-AGENT (gap #6/#7 partial), PH-QM stub
Author: agent

Summary (one sentence)

Studio MCP contracts extend to eight tool IDs (am_export_print, chem_dft_run, studio_adaptive_layout), studio_mcp_tool_dispatch stub, li-chem chem_dft_run_smoke, and smokes — no lis HTTP server.

Agent continuation (required)

  1. Read: docs/game-dev/studio-mcp-tools.md, packages/li-studio/src/lib.li (PH-AGENT block), packages/li-chem/src/lib.li.
  2. Run: lic check packages/li-studio/li-tests/smoke/studio_mcp_extended.li; lic check li-tests/composable/import_lig_chem_backend.li.
  3. Then: AGENT-1 — register eight tools in lis mcp li-engine; wire chem_dft_run to real li-chem queue and am_export_print to additive export pipeline.
  4. Blocked on: MCP HTTP transport and ORCA/Psi4 backends — none for this contract merge.

Changed (specific)

Area What Evidence
docs/game-dev/studio-mcp-tools.md Tool table + dispatch API; gap #6/#7 rows agent-readable contract
runtime/li_rt.c Names am_export_print, chem_dft_run, studio_adaptive_layout (IDs 6–8) studio_mcp_tool_name round-trip
packages/li-studio studio_mcp_am_export_print, studio_mcp_chem_dft_run, studio_mcp_studio_adaptive_layout, studio_mcp_tool_count → 8, studio_mcp_tool_dispatch li-tests/smoke/studio_mcp_extended.li, updated studio_mcp_tools.li
packages/li-chem chem_dft_run_smoke(), chem_dft_energy_stub_hartree() (−76.0); chem_lig_backend_auto unchanged li-tests/composable/import_lig_chem_backend.li

Not changed (scope fence)

  • lis MCP HTTP server — not implemented.
  • @cursor/sdk session wiring — not in this PR.
  • Real printer export, DFT queue execution, or adaptive panel content — stubs/contracts only.
  • li_std_studio_version — remains 6 (no bump).
  • LLVM / httpd / tier5 / proof-db — not touched.

Breaking / Security / Performance / Downstream

  • Breaking: studio_mcp_tool_count() is 8 (was 5); consumers hard-coding count 5 must update.
  • Security: N/A — stub IDs and dispatch only, no network surface.
  • Performance: N/A — O(1) name table lookup.
  • Downstream: MCP server agents should use documented tool names for gap #6/#7 before AGENT-1 registration.
