What it does
Et Async is an agent skill from FlameskyDexive/Legends-Of-Heroes. ET async and EntityRef safety workflow. Use when adding, modifying, or reviewing async/await, ETTask, generic ETTask results, ETCancellationToken, NewContext, concurrent waits, handler Run async safety, or any Entity access after await in WOW/ET code or tests.
Its SKILL.md is about 330 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/et-async-rules.md`).
It sits in Development, covering Async programming. The repository describes itself as: A battle of balls game, lol style, AI Agents base, support agent skills & unityMCP. 基于ET 10的双端C游戏框架(.net10 + Unity2022.3.62, EUI+Luban+YooAsset)，包含战斗系统（技能/buff/行为树），内置LOL风格球球大战demo. The licence is MIT.
When your agent uses it
- Reviewing async/await
- Generic ETTask results
- ETCancellationToken
- Concurrent waits
Example prompts
- “/et-async”
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- 先判断是否真的需要异步，并明确谁在等待返回值。
- 只有 RPC、IO、定时器、协程锁、跨 Fiber 结果或其它真实异步资源，才保留 async / ETTask。
- 调用方不依赖返回值时，优先改成同步方法、普通消息、Send 或独立协程。
- 只要存在 await 后继续访问 Entity 的路径，就在 await 前创建 EntityRef，并在 await 后重新获取。
- 函数参数可以传 Entity；字段、属性、集合中保存 EntityRef，不要长期持有 Entity。
- 在消费结果的协程里直接 await；不要设计“返回一个 ETTask 句柄，后面再 await”的桥接层。
- NewContext(...) 只承担独立协程与取消边界；需要携带实体时使用 EntityRef。
What it can do on your machine
Read from SKILL.md and the folder at commit 0bd8ac1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Et Async loads about 332 tokens when it runs, and up to ~1k if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 86 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

et-async - ET Async 入口
何时使用
- 新增、修改或 review
async/await/ETTask/ETTask<T> - 判断某段逻辑是否应该异步化，或是否应该改回同步
- 处理
await后Entity访问、EntityRef<T>、HandlerRun异步安全 - 设计并发等待、
ETTask.WaitAll(...)、ETCancellationToken、NewContext(...)
不要加载
- 代码完全同步，且不涉及异步边界、安全或取消控制
- 只是编译、导出、跑测试、操作 Unity / Excel
默认动作
- 先判断是否真的需要异步，并明确谁在等待返回值。
- 只有 RPC、IO、定时器、协程锁、跨 Fiber 结果或其它真实异步资源，才保留
async/ETTask。 - 调用方不依赖返回值时，优先改成同步方法、普通消息、
Send或独立协程。 - 只要存在
await后继续访问 Entity 的路径，就在await前创建EntityRef<T>，并在await后重新获取。 - 函数参数可以传 Entity；字段、属性、集合中保存
EntityRef<T>，不要长期持有 Entity。 - 在消费结果的协程里直接
await；不要设计“返回一个ETTask句柄，后面再 await”的桥接层。 NewContext(...)只承担独立协程与取消边界；需要携带实体时使用EntityRef<T>。
快速分流
EntityRef正误示例、并发等待、取消控制：补读references/et-async-rules.md- Handler
Run、组件契约、包结构：叠加et-code - 测试里的异步等待：叠加
et-test-write
输出要求
- 说明异步是否必要，以及谁在等待结果
- 说明
await后实体访问是否通过EntityRef<T>保护 - 说明并发组织方式是否避免延后消费
ETTask - 说明
ETCancellationToken/NewContext(...)是否只承担取消与协程边界职责
