Greptile Summary
This PR implements comprehensive improvements to brace validation and script editing functionality across the Unity MCP Bridge system. The changes focus on enhancing the reliability of C# code parsing, validation, and modification operations within Unity projects.
The core improvements center around the ManageScript.cs tool, which now features enhanced null parameter validation, improved scoped balance checking with better tolerance for context outside editing regions, and refined refresh/compile behavior with both immediate and debounced modes. The validation logic has been strengthened with relaxed brace tolerance (-3 instead of -1) to handle legitimate edits within larger code contexts while maintaining final structural validation.
A new ComponentResolver system has been introduced in ManageGameObject.cs that provides robust component type resolution with assembly prioritization, caching, and AI-powered property suggestions using Levenshtein distance calculations. This system handles Unity's complex assembly loading patterns and provides helpful error messages with suggestions when property names don't match exactly.
The script editing infrastructure has been enhanced with improved anchor matching heuristics in manage_script_edits.py. New functions like _find_best_anchor_match() and _find_best_closing_brace_match() use scoring algorithms to intelligently select the best insertion points for code modifications, particularly for class-level changes where multiple closing braces exist.
Logging has been standardized throughout the codebase by replacing direct Debug.Log calls with McpLog helper methods, providing consistent formatting and better control over debug output. The system now distinguishes between benign network errors and actual problems requiring developer attention.
The testing infrastructure has been significantly expanded with comprehensive test suites for component resolution, property matching, script validation, and GameObject management. New test assemblies and components have been added to validate the improved functionality across various scenarios.
Version numbers have been coordinated across the system, bumping from 3.1.0/3.1.1 to 3.2.0/3.3.0 to reflect these substantial improvements. The changes also include architectural improvements like moving reload sentinel functionality from external Python scripts to Unity menu items, and switching from immediate to debounced refresh patterns for better editor performance.

tests/test_improved_anchor_matching.py (4)
10-14: Avoid leaking sys.path mutations across the test sessionModifying sys.path at module import time can affect other tests. Prefer a pytest fixture that inserts SRC and restores sys.path after the module completes.
Example fixture (place in tests/conftest.py or at top of this file and import/use):
import sys, pathlib, pytest @pytest.fixture(scope="module", autouse=True) def _patch_sys_path(): root = pathlib.Path(__file__).resolve().parents[1] src = root / "UnityMcpBridge" / "UnityMcpServer~" / "src" old = list(sys.path) sys.path.insert(0, str(src)) try: yield finally: sys.path[:] = old
31-35: Guard against None spec/loader in load_moduleimportlib.util.spec_from_file_location can return None (or a spec with loader=None). Add a defensive check to fail fast with a clear error.
def load_module(path, name): - spec = importlib.util.spec_from_file_location(name, path) - module = importlib.util.module_from_spec(spec) - spec.loader.exec_module(module) + spec = importlib.util.spec_from_file_location(name, path) + if spec is None or spec.loader is None: + raise ImportError(f"cannot load {name} from {path}") + module = importlib.util.module_from_spec(spec) + spec.loader.exec_module(module) return module
144-150: Replace assert False and make line-splitting platform-safe
- Avoid assert False (ruff B011) and use a None default with next().
- Use splitlines() for CRLF/CR handling.
- lines = result.split('\n') - try: - idx = next(i for i, line in enumerate(lines) if "NewMethod" in line) - except StopIteration: - assert False, "NewMethod not found in result" - total_lines = len(lines) + lines = result.splitlines() + idx = next((i for i, line in enumerate(lines) if "NewMethod" in line), None) + assert idx is not None, "NewMethod not found in result" + total_lines = len(lines) assert idx >= total_lines - 5, f"method inserted too early (idx={idx}, total_lines={total_lines})"
152-170: Remove the main runner or delegate to pytestThe test functions don’t return booleans; this block always prints failure when run directly and is redundant under pytest.

118-118: Pattern detection logic is acceptable for its intended use.The pattern
'}' in patterncheck provides a reasonable heuristic for identifying closing brace patterns. While it could theoretically match unrelated patterns, it's appropriately scoped for Unity C# script editing where this pattern is meaningful.
180-180: Method signature detection is appropriately scoped.The regex pattern
r'\b(void|public|private|protected)\s+\w+\s*\('is designed for C# method signatures in Unity scripts. While it could match properties or events, the penalty application is conservative and appropriate for the heuristic scoring context.

5-5: LGTM!The import addition is appropriate for the file operations used later in the code.
43-51: Improved anchor matching with robust heuristics.The implementation correctly replaces direct regex usage with the new
_find_best_anchor_matchfunction that provides better heuristics for finding appropriate matches, especially for class-ending braces.
86-125: Well-designed anchor matching with semantic awareness.The
_find_best_anchor_matchfunction provides intelligent heuristics for choosing the best match when multiple candidates exist. The special handling for closing brace patterns and theprefer_lastparameter make the anchor resolution more reliable for Unity C# scripts.
128-193: Sophisticated scoring algorithm for C# structure awareness.The
_find_best_closing_brace_matchfunction implements comprehensive heuristics that consider indentation levels, proximity to EOF, and method signatures. This should significantly improve the accuracy of class-ending brace detection.
207-207: LGTM! Validation delegation to Unity compiler services.Removing the internal structural balance validation and delegating this responsibility to Unity's compiler services is a sound architectural decision that leverages Unity's built-in capabilities.
537-551: Improved refresh strategy for structured edits.The preference for immediate refresh on structured edits makes sense to avoid missed reloads when the Unity Editor is unfocused. The removal of optional sentinel reload logic simplifies the flow.
596-597: Consistent use of improved anchor matching.Good application of the new
_find_best_anchor_matchfunction in the mixed batch processing path, maintaining consistency across different code paths.
666-666: Smart default for mixed edit operations.The debounced refresh default for mixed operations balances performance with reliability, while allowing explicit override when needed.
671-671: LGTM! Sentinel reload cleanup.The removal of optional sentinel reload logic simplifies the codebase while maintaining the core functionality. The deprecated behavior is properly cleaned up.
Also applies to: 689-691
677-678: Appropriate refresh strategy for subsequent structured edits.Using debounced refresh for structured edits in mixed batches is sensible to avoid overwhelming Unity with rapid refresh requests.
720-724: Enhanced anchor matching with improved error handling.The consistent application of
_find_best_anchor_matchwith proper flag handling and clear error messages improves the reliability of anchor-based operations.
765-766: Consistent anchor matching across all paths.Good use of the unified
_find_best_anchor_matchfunction in the regex_replace path, ensuring consistent behavior across different operation types.
773-773: LGTM! Proper delegation to Unity's validation.The comment correctly indicates that validation is now handled by Unity's built-in compiler services, which is more reliable than custom validation logic.
787-788: Clear error handling for empty edit operations.The
no_spanscheck provides a helpful error message when no applicable edits are computed, improving the user experience when anchors aren't found.
802-802: Consistent debounced refresh strategy.The default to debounced refresh across different text edit paths provides a good balance between responsiveness and performance, while still allowing explicit override when needed.
Also applies to: 808-810, 861-861, 886-886, 890-892

39-41: Align default anchor_insert position: currently inconsistent and likely wrong for class-end inserts.
_apply_edits_locallydefaults to "before", but the mixed/text conversion paths default to "after". For class-closing-brace anchors, "after" places text outside the class.

uses ComponentResolver which only resolves Component/MonoBehaviour types so
ScriptableObject types never resolve; add a new helper
TryResolveScriptableObjectType (place it near the other helper methods in the
file) that attempts direct Type.GetType, uses UnityEditor.TypeCache for editor
builds, and falls back to scanning loaded assemblies while handling
ReflectionTypeLoadException, and then replace the ComponentResolver.TryResolve
call with TryResolveScriptableObjectType to set scriptType/out error and keep
the existing validation and error-return logic.

596-603: Respect per-edit prefer_last consistently.Hard-coding
prefer_last=Trueignores caller intent. Usee.get("prefer_last", True)as shown in the earlier diff.Also applies to: 721-724
711-789: De-dup shared utilities to reduce drift.
line_col_from_indexappears in multiple branches. Consider a single helper (module-level) to avoid subtle off-by-one inconsistencies.
70-80: Narrow exception handling around regex operations.Catching
Exceptionmasks unrelated issues. Preferre.errorfor compile failures; use explicit guards elsewhere. Optional given structured error shaping.Also applies to: 620-629, 757-765

5-5: No action — benign import.Leaving
import osis harmless if you plan to use it soon. If not, consider removing in a later cleanup.
207-207: Confirm structural validation handoff.With
_is_structurally_balancedremoved, ensure Unity’smanage_scriptvalidators run for both structured and text paths (including atomic text batches) underoptions.validate='standard'.
537-539: Good default: immediate refresh for structured edits.This reduces missed reloads when the Editor is unfocused.
666-667: Routing/options hygiene looks solid.Atomic apply for multi-span text edits, debounced refresh on text paths, and precondition SHA usage are all appropriate.
Also applies to: 802-805, 861-862, 886-887
549-551: Replace deprecated sentinel with direct compilation trigger – verify reload reliability
Structured/text edits now invokeUnityEditor.Compilation.CompilationPipeline.RequestScriptCompilation()instead of flipping the sentinel. Confirm that this consistently forces Unity to recompile/reload in the Editor, and consider preserving theexecute_menu_item("MCP/Flip Reload Sentinel")path behind a feature flag as a fallback if needed.
38-52: Ignore incorrect default-position inconsistency suggestion.
Allanchor_insertcalls use the same code path inmanage_script_edits.py, where the defaultpositionis"before". There is no alternate “after” default in any server or resource‐tools implementation.Likely an incorrect or invalid review comment.
