# Sprint 9 Progress — Agent-First Tooling

## Phase 9a: Standalone MCP Server

### Step 245: HeadlessEditorState (no ImGui dependency)
**Status:** PASS (20/20 tests)

Created the headless agent API surface — same method interface as EditorState
but with zero GUI dependencies (no ImGui, no SDL, no WebSocket).

**Files created:**
- `editor/src/ASTUtils.h` — Pure AST utility functions extracted from EditorUtils.h
  (cloneModule, isAnnotationNode, countAnnotationNodes, findNodeById, findNodeAtPosition)
- `editor/src/HeadlessEditorState.h` — Lightweight state: HeadlessAgentState,
  HeadlessLibraryState, HeadlessBufferState, buffer management, orchestrator sync
- `editor/src/HeadlessAgentRPCHandler.h` — Full RPC dispatch mirroring
  AgentRPCHandler.h (20+ methods: getAST, parseSource, runPipeline, applyMutation,
  applyBatch, projectLanguage, generateCode, workflow recording, etc.)
- `editor/tests/step245_test.cpp` — 20 test cases covering construction, buffer
  management, RPC dispatch, permission enforcement, pipeline execution

**Key design decisions:**
- JSON roundtrip cloning (matching EditorUtils.h) instead of manual deep copy
- Separate HeadlessAgentState (no AgentMarketplace/WebSocket dependency chain)
- All files under 600-line architecture limit
