added tool/functions for manage_prefab and refactored manage_gameobje…

[chennan820]

tested create prefab, modify prefab, delete prefab using Claude CLI client.

Summary by CodeRabbit

• New Features

  • Introduced a comprehensive prefab management tool supporting create, instantiate, open/close, save, modify, find, get info, variant, and unpack. Available in the MCP tool list.

• Refactor

  • Prefab operations are redirected from game object management to the new prefab tool. Game object management now targets scene objects only, with updated instantiation flow and clearer success messages. get_components can include non-public serialized components.

• Documentation

  • Updated tool descriptions and error messages to guide users to the new prefab tool for prefab-related tasks.

Walkthrough

Adds a dedicated prefab management tool across editor and server layers. Introduces ManagePrefab.cs with a new “manage_prefab” command and routes/registry entries. Updates manage_gameobject and manage_asset to defer prefab work to the new tool. Extends Python MCP tooling to register and expose manage_prefab; adjusts docs/strings accordingly.

Changes

Cohort / File(s)	Summary of Changes
Command routing (Editor) UnityMcpBridge/Editor/MCPForUnityBridge.cs, UnityMcpBridge/Editor/Tools/CommandRegistry.cs	Add dispatch/registry entries mapping "manage_prefab" to ManagePrefab.HandleCommand; existing routing unchanged.
Prefab tool implementation (Editor) UnityMcpBridge/Editor/Tools/ManagePrefab.cs, UnityMcpBridge/Editor/Tools/ManagePrefab.cs.meta	New public static class ManagePrefab with HandleCommand and action handlers (create, instantiate, open, close, save, modify, find, get_info, variant, unpack). Adds meta file with GUID.
GameObject/Asset tools adjustments (Editor) UnityMcpBridge/Editor/Tools/ManageGameObject.cs, UnityMcpBridge/Editor/Tools/ManageAsset.cs	ManageGameObject blocks prefab operations and redirects users to manage_prefab; removes save-as-prefab flow and updates get_components call. ManageAsset prefab branch now errors with instruction to use manage_prefab; removes old prefab comments.
Server tool registration and descriptions UnityMcpBridge/UnityMcpServer~/src/server.py, UnityMcpBridge/UnityMcpServer~/src/tools/__init__.py	Updates asset_creation_strategy text; adds register_manage_prefab_tools import and invocation to include the new tool in MCP registration.
Python tools: API separation UnityMcpBridge/UnityMcpServer~/src/tools/manage_gameobject.py, UnityMcpBridge/UnityMcpServer~/src/tools/manage_prefab.py	manage_gameobject: removes prefab-related params/logic; clarifies scope to scene objects. manage_prefab: new tool supporting create/instantiate/open/close/save/modify/find/get_info/variant/unpack; builds params and dispatches to Unity via "manage_prefab".

Poem

A prefab hop, a sculpted scene,
I nibbled code where assets preen.
New trails to build, instantiate—
Carrots queued, I automate.
From gameobject to prefab’s art,
I twitch, I merge—a hopping start. 🥕✨

Tip

👮 Agentic pre-merge checks are now available in preview!

Pro plan users can now enable pre-merge checks in their settings to enforce checklists before merging PRs.

• Built-in checks – Quickly apply ready-made checks to enforce title conventions, require pull request descriptions that follow templates, validate linked issues for compliance, and more.
• Custom agentic checks – Define your own rules using CodeRabbit’s advanced agentic capabilities to enforce organization-specific policies and workflows. For example, you can instruct CodeRabbit’s agent to verify that API documentation is updated whenever API schema files are modified in a PR. Note: Upto 5 custom checks are currently allowed during the preview period. Pricing for this feature will be announced in a few weeks.

Example:

reviews:
  pre_merge_checks:
    custom_checks:
		  - name: "Undocumented Breaking Changes"
			  mode: "warning"
			  instructions: |
				  Flag potential breaking changes that are not documented:
				  1. Identify changes to public APIs/exports, CLI flags, environment variables, configuration keys, database schemas, or HTTP/GraphQL endpoints (including removed/renamed items and changes to types, required params, return values, defaults, or behavior).
				  2. Ignore purely internal/private changes (e.g., code not exported from package entry points or marked internal).
				  3. Verify documentation exists: a "Breaking Change" section in the PR description and updates to CHANGELOG.md.
