implement

A command for carrying out a planned feature in several stages, with review and validation points along the way. It uses a feature plan stored under the project’s rpi folder and places implementation work in a matching output folder.

In plain words
What is it for?
Use it to start or validate an implementation phase, run a particular phase, or carry out the project’s full eight-phase implementation workflow.
Why use it?
It gives a large change a defined sequence and checks progress against project rules instead of treating implementation as one untracked step.

Made for: Claude Code.

Per session 10 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 4,278 The whole file, excluding the scripts and references it only reads on demand.

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

implement 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 3d 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.

用户输入

$ARGUMENTS

必须解析用户输入以提取功能 slug(rpi/ 中的文件夹名称)。

目的

此命令根据规划文档执行功能的分阶段实施。它编排专业 agent,强制执行验证关卡,并确保在整个实施过程中符合宪法。

前置条件

  • 功能文件夹存在于 rpi/{feature-slug}/
  • 规划完成(rpi/{feature-slug}/plan/PLAN.md 存在)

输出位置rpi/{feature-slug}/implement/

这是 RPI 工作流的步骤 4(最后一步 - 实际实施)。

标志

  • --phase N:执行特定阶段编号(1-8),如果省略则从阶段 1 开始
  • --validate-only:仅验证当前阶段,不实施
  • --skip-validation:跳过验证关卡并继续(谨慎使用)

可用 Agent

所有 Agent 使用 Opus 模型以获得最大质量。

实施 Agent

Agent 类型 何时使用

Agent 类型 目的

code-reviewer 自定义 代码评审和质量验证

所有实施任务由 senior-software-engineer agent 处理。


阶段 0:加载上下文和规则

前置条件:从用户输入解析功能 slug

流程

0.1 加载项目宪法

  1. 在代码库中检查宪法或原则文档
  2. 如果存在,提取:
    • 技术约束(类型安全、测试、组件隔离)
    • 业务原则(质量标准、工作流)
    • 架构边界
  3. 在实施期间存储约束以便强制执行

0.2 加载领域特定指南

根据要修改的文件,加载相关的项目指南:

  • 检查特定组件的 README 文件
  • 检查编码风格指南
  • 检查测试需求文档

0.3 分析实施范围

  1. 读取 rpi/{feature-slug}/plan/PLAN.md
  2. 识别所有要修改的文件
  3. 将文件映射到实施 agent

输出

  • 宪法上下文摘要
  • 领域规则已加载
  • 文件到 agent 的映射
  • 阶段执行计划

验证

  • 宪法已加载(如果存在)
  • 受影响文件的领域规则已加载
  • 所有文件已映射到 agent
  • 执行计划已理解

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.

implement is a command published in the GitHub repository BuaaJoseph/claude-code-best-practice-zh (2 stars, last pushed 4mo ago), licensed MIT. It adds 10 tokens to every session and 4,278 once invoked, about $0.0001 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.
