Check bridge/editor health: engine version, project name, loaded bridge API list. Call this first to confirm the editor is reachable before any write operation. Returns {engine_version, project, bridge_apis[]}. | 健康检查：引擎版本、项目名、bridge API 清单；任何写操作前先调用。

Full bridge diagnostics: complete C++ API method matrix and any missing critical APIs. Use when a tool fails with an API-missing error, or after upgrading/replacing the bridge DLL. | Bridge 诊断：全部 C++ API 方法矩阵 + 关键 API 缺失项。

List asset paths under a content folder (default /Game/). Use to discover what exists before reading or editing. recursive=true walks subfolders. | 列出 /Game 资产路径（recursive 控制是否递归）。

Read a Blueprint asset: level L1 = class info + variables + CDO, L2 = node graph + connections, full = both. Read-only and safe to call any time. Returns structured JSON (Markdown/Mermaid reports available via the CLI reader). | 读取蓝图（L1 类信息+变量+CDO / L2 节点+连线 / full）。

Read Blueprint nodes: titles, positions, GUIDs and pin defaults. Omit graph_name to search all graphs. Use before connecting pins so you have the GUIDs. | 读取蓝图节点（不传 graph_name = 全图搜索）。

Read the Blueprint's connection topology (which pin connects to which node/pin). Use to verify wiring before and after edits. | 读取蓝图连线拓扑。

Create a Blueprint from scratch in one atomic call: asset + variables + components + interfaces + events + function nodes + connections + optional compile. If any step fails, assets created by this call are rolled back. spec fields: blueprint_name (or name), package_path, parent_class, variables[{name,type,default_value,category}], components[{name,component_class,properties}], interfaces[str], events[{event_name|name,pos}], functions[{function_name|name, target_class, function_path, defaults:{pin:val}, pos}], connections[{src_node,src_pin,dst_node,dst_pin}], compile_after. Node references accept 32-hex GUIDs (recommended) or titles. | 创建蓝图（原子化：失败回滚已建资产）。

Create multiple Blueprints in one atomic batch: if any blueprint fails, all assets created by this batch are rolled back. Prefer ue5_build_blueprint unless multi-asset atomicity is actually needed. | 批量创建蓝图（原子化：任一失败回滚本批已建资产）。

Compile a Blueprint, read back the compile status and scan the log for error patterns. The real compile result is reported: a failed compile returns failure with log evidence, never a fake success. | 编译蓝图 + 回读编译状态 + 日志错误模式扫描。

Connect pins with triple topology verification (existence, type compatibility, read-back). Node references accept titles or 32-hex GUIDs; ambiguous titles are rejected (fail-loud) — use GUIDs when titles repeat. | 引脚连线（三重拓扑验证；标题歧义 fail-loud 拒绝）。

Disconnect every connection attached to one pin of a node, verified against the live topology. | 断开节点某引脚的全部连线（按实时拓扑验证）。

Delete a Blueprint node. dry_run=true only checks references without deleting — use it first for nodes that may be referenced elsewhere. | 删除节点（dry_run 仅检查引用，不删除）。

Save an asset to disk; only_if_is_dirty=true skips clean packages. Saves are scoped to the asset's own package — this tool never triggers a whole-project save. | 保存资产落盘（only_if_is_dirty=true 仅脏包写盘；作用域=该资产包，绝不全工程保存）。

Delete an asset with reference checks and read-back verification. Save scope = referencing packages only. | 级联删除资产（删后回读验证；保存作用域=引用者包）。

Start PIE (play/simulate) asynchronously. Poll with ue5_read_pie_state until is_playing=true. Use to verify that logic actually RUNS, not just that it compiles. | 启动 PIE/Simulate（异步；用 ue5_read_pie_state 轮询确认）。

Stop the running PIE/Simulate session. | 结束 PIE/Simulate 会话。

Read PIE state: is_playing, world name, paused, game time. Poll this after ue5_start_pie before reading runtime actors/properties. | PIE 状态：is_playing / 世界名 / 暂停 / 游戏时间。

Enumerate live Actors in the PIE world (runtime objects; their paths contain UEDPIE_0_). Filter by actor_class and/or name_filter substring; limit caps the result count. | 枚举 PIE 世界 Actor（运行时对象）。

Read a runtime Actor property in PIE; omit property_name to list candidate property names first. Use this to prove game logic ran (e.g. health changed after a pickup). | 读 PIE 中 Actor 属性（property_name 空 = 列候选属性名）。

Teleport a PIE Actor at runtime (location and/or rotation, at least one), with read-back verification of the new transform. | 运行时传送 PIE Actor（location/rotation 至少一个；带回读验证）。

Read the UE log: cursor=0 returns the tail (last lines); cursor>0 returns only new lines after that cursor (incremental polling). Filter by category/pattern. Use for self-service cross-checks of any operation. | 读 UE 日志（cursor=0 取尾部；cursor>0 增量取新增；category/pattern 过滤）。

Execute a whitelisted-command batch in one request (multi-step task in a single round trip); stops on the first failing step by default. For a single operation prefer the dedicated tool — this is for sequences. | 白名单命令批量执行（单次请求多步；任一步失败默认中止）。

Escape hatch: run any whitelisted bridge command by name — the full 72-command surface, including capabilities without a dedicated tool (materials, UMG widgets, and other advanced operations). Prefer the dedicated tool whenever one exists for the operation; this generic entry point is the last resort and its arguments are less validated. command ∈ add_actor_bound_event_node, add_async_action_node, add_cast_node, add_class_cast_node, add_comment_node, add_component, add_component_bound_event_node, add_composite_node, add_create_delegate_node, add_custom_event_node, add_enum_literal_node, add_event_dispatcher, add_function_node, add_function_pin, add_implemented_interface, add_input_action_event_node, add_input_axis_event_node, add_input_key_event_node, add_local_variable, add_macro_node, add_math_expression_node, add_pin_to_node, add_struct_node, add_switch_node, add_timeline_node, add_variable, add_variable_node, build_blueprint, compile_blueprint, connect_pins, create_node_by_class, delete_asset, editor_batch, find_actors, get_actor_properties, get_node_by_guid, get_pin_default_value, health, list_assets, logs_read, material_add_expression, material_compile, material_connect_expressions, material_connect_property, material_create, material_instance_create, material_instance_set_parameter, material_read, material_set_expression_property, pie_start, pie_state, pie_stop, read_blueprint, read_cdo, read_connections, read_nodes, read_variables, remove_component, remove_pin_from_node, save_asset, set_actor_transform, set_class_default, set_node_position, set_node_property, set_pin_default_value, spawn_actor, try_node_add_input_pin, unpin_console_refs, widget_add_child, widget_create, widget_read_tree, widget_set_property；params 为该命令入参对象。未登记命令 fail-loud 拒绝。| 白名单命令透传（专用工具未覆盖时使用）。
