      "summary": "\n\nPlanning is complete. Here's the summary:\n\nThe spec calls for a tree-sitter layer that provides zero-config code intelligence as a fallback when no LSP server is running. The plan covers:\n\n**New files (5):**\n- `src/tree-sitter/parser-manager.ts` — WASM parser loading/caching per language\n- `src/tree-sitter/symbol-extractor.ts` — AST walking to extract symbols, find definitions, get node info at positions\n- `src/tree-sitter/workspace-index.ts` — project-wide symbol index (capped at 5k files, incremental updates)\n- `src/resolve-provider.ts` — routing helper: LSP → tree-sitter → \"no intelligence available\"\n- `src/tools/code-overview.ts` — new tool for project structure summaries\n\n**Modified files (6):**\n- `src/tools/symbols.ts`, `definition.ts`, `hover.ts`, `diagnostics.ts` — each gets a tree-sitter fallback path\n- `src/index.ts` — wire up TreeSitterManager, WorkspaceIndex, register code_overview\n- `src/file-sync.ts` — invalidate tree-sitter cache on file changes\n\n**Dependencies:** `web-tree-sitter` + `tree-sitter-wasms` (pre-built grammar WASMs, loaded lazily per language)\n\n**Key design decisions:**\n- Grammars come from `tree-sitter-wasms` npm package (lazy-loaded, no download script)\n- LSP always takes priority; tree-sitter is fallback only\n- Workspace index caps at 5000 files initially, indexes remaining on demand\n- Same output formats as existing LSP tools so the LLM sees consistent results\n\nThe scratchpad has the full step-by-step breakdown. Ready for the Builder hat.",

      "summary": "Implementation complete. Here's what I built:\n\n5 new files and 6 modified files implementing the tree-sitter integration spec. The core layer (`parser-manager.ts`, `symbol-extractor.ts`, `workspace-index.ts`) provides WASM-based parsing with per-language symbol extraction for TS/JS, Python, Rust, Go, Java, C/C++, and Ruby. The `resolve-provider.ts` routes each tool call to LSP (if running) or tree-sitter (fallback). All four existing tools (`symbols`, `definition`, `hover`, `diagnostics`) now gracefully degrade to tree-sitter when no LSP server is available. A new `code_overview` tool summarizes project structure using tree-sitter symbol extraction.\n\nKey discovery during implementation: `web-tree-sitter@0.26.x` has ABI incompatibility with `tree-sitter-wasms` pre-built grammars — pinned to `0.24.7` which works correctly. All grammars load and parse successfully, and the project compiles cleanly with zero TypeScript errors.",

      "summary": "## Review Summary: ✅ Pass (2 fixes applied)\n\n### Bugs Fixed\n\n1. **`export_statement` dead code** (high severity) — `TS_JS_SYMBOLS` included an `export_statement` mapping that shadowed the intended unwrapping logic in `extractFromNode`. All exported TS/JS declarations were either incorrectly named or silently dropped. **Fixed** by removing the conflicting mapping entry. Verified all export patterns now extract correctly.\n\n2. **Unused `prefix` parameter** (low) — `WorkspaceIndex.addSymbols()` had a dead `prefix?` parameter. Removed.\n\n### Spec Compliance: Complete\nAll requirements met — zero-config fallback for 19 languages, graceful LSP→tree-sitter routing, `code_overview` tool, workspace indexing with 5000-file cap, FileSync integration, `[tree-sitter]` annotations, and syntax-only diagnostic disclaimer.\n\n### Compilation: Clean\n`tsc --noEmit` passes. WASM ABI compatibility verified at runtime.",
