parallel-feature

parallel-feature is a skill for Claude Code from grasscaograss/AwesomeWeldoneSkills. It costs 94 tokens per session (1,067 once invoked), scanned A, original, Apache-2.0.

A staged workflow for building features across several parts of a codebase with multiple agents. It defines shared interfaces first, assigns files to agents, then combines and checks the work.

In plain words
What is it for?
Use it to plan and coordinate parallel feature development, generate agent instructions, keep each agent within an assigned file area, and check the build, tests, and acceptance conditions.
Why use it?
It reduces conflicting edits and unclear handoffs when a feature spans the domain logic, application code, user interface, and tests.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

parallel-feature scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

并行 Feature 开发

三阶段工作流:契约 → 并行施工 → 集成验收

阶段 1:生成接口契约

收到用户功能描述后,先读取相关现有代码,生成接口契约文档,等用户确认后再进入阶段 2

契约必须包含以下内容:

## Feature: <功能名称>

### 共享契约

#### 新增类型/接口
- 列出所有新增的 DTO、接口、枚举,包含完整字段签名

#### 已有类型(只读引用,禁止修改)
- 列出将被引用但不应改动的现有类型

#### 调用链
- 用箭头表达完整调用链路:UI → AppService → Domain → Storage

### 文件归属

| Agent | 职责 | 可编辑文件 | 禁止触碰 |
|-------|------|-----------|---------|
| A 领域层 | 实体/DTO/接口定义 | `src/...Domain/.../*.cs`, `src/...Contracts/.../*.cs` | 应用层、前端 |
| B 应用层 | AppService 实现 | `src/...Application/.../*.cs` | 领域层定义、前端 |
| C 前端 | Blazor 组件 | `src/...Blazor/**/*.razor`, `*.razor.cs` | 后端全部 |
| D 测试 | 单元测试 | `test/**/*Test*.cs` | 源码文件 |

### 验收标准
- `dotnet build` 0 error
- 指定的测试全部通过
- 明确的功能验收条件

文件归属自动推断规则

路径模式 归属 Agent
src/**/Domain/**/*.cs A 领域层
src/**/Contracts/**/*.cs A 领域层
src/**/Application/**/*.cs B 应用层
src/**/Blazor/**/*.razor* C 前端
src/**/HttpApi/**/*.cs B 应用层
test/**/*Test*.cs D 测试

如果功能较简单(只涉及 2 个切面),合并为 2 个 agent 即可,不必强行凑 4 个。

阶段 2:并行施工

用户确认契约后,为每个 Agent 生成独立 prompt,在同一条消息中用多个 Agent tool 调用并行启动

每个 Agent prompt 必须包含:

  1. 完整的共享契约(类型签名、调用链)
  2. 该 Agent 的文件归属范围
  3. 明确的禁止触碰文件列表
  4. 具体的实现要求

Agent prompt 模板:

你是 <角色> Agent。功能:<功能描述>

## 共享契约
<完整契约内容>

## 你的职责
- 可编辑:<文件列表>
- 禁止触碰:<文件列表>

## 实现要求
<该切面的具体实现指引>

## 约束
- 不得修改共享契约中定义为"只读引用"的类型
- 不得编辑归属范围外的文件
- 方法签名必须严格匹配契约定义
- 完成后列出所有新增/修改的文件

阶段 3:集成验收

所有 Agent 返回后,执行:

  1. 冲突检查:读取每个 Agent 修改的文件,检查是否有交叉修改
  2. 签名一致性:验证接口方法签名在各层之间一致
  3. 构建验证:运行 dotnet build --no-restore
  4. 结果报告:汇总每个 Agent 的变更,报告构建结果

如果构建失败:

  • 分析错误,定位到具体 Agent 的输出
  • 启动修复 Agent 修复冲突/签名不一致问题
  • 最多重试 2 次,仍失败则报告给用户

阶段 4(可选):补测试

如果契约中有测试 Agent(D),它会并行运行。如果没有,集成验收通过后询问用户是否需要补写测试。

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

parallel-feature is a skill published in the GitHub repository grasscaograss/AwesomeWeldoneSkills (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 94 tokens to every session and 1,067 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
