What it does

Sdd Riper One Light is an agent skill from openyida/openyida. 面向 GPT-5.5 等强模型和熟练用户的轻量 AI Agent Harness / checkpoint-driven coding skill。默认用户已经把任务切到基本可执行的最小混沌单元;模型自行分解、探索与推进,人类通过最终目标、最小 spec、复述、checkpoint、证据验证与回写来低干扰控盘。

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 24 other files, including scripts and reference files (for example `README.md`, `agents/openai.yaml` and `examples/README.md`).

It sits in Agent Workflows. It works with OpenAI. The repository describes itself as: Your own personal YiDA AI assistant! The licence is MIT.

When your agent uses it

  • Agent Workflows work in your project

Example prompts

  • “/sdd-riper-one-light”

What it can do on your machine

Read from SKILL.md and the folder at commit b52e65e. 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

    Ships 1 file in scripts/, which the agent can run.

    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

Sdd Riper One Light loads about 1.5k tokens when it runs, and up to ~7.8k if it reads all its reference files. Until then it costs about 44 tokens; SKILL.md has 385 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.8k

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); the scripts in this folder are not scanned.

SDD-RIPER-ONE Light

核心定位

  • 这是面向强模型的轻量 AI Agent Harness,不是 phase-heavy 版本。
  • 默认承认模型已经从“助手”变成事件推进的主体:模型负责分解、探索、试错和推进;人类负责方向、边界、节奏、风险与验收。
  • 默认面向熟练用户、强模型和已经被用户拆得还不错的任务;它是无感安全带,不是 Harness 教练。
  • 默认假设强模型已经能自行分解任务、补足局部计划、按需追溯上下文。
  • 默认不主动做重度任务拆分,不频繁讲解理论,不把每一步都变成审批点。
  • 主协议只保留少数高杠杆锚点,其余规范按需查看 reference。
  • 目标不是减少控制力,而是减少低价值常驻 token。
  • 不节约有效 token,但节约上下文:常驻只保留运行内核,模板、教学、诊断与长规则按需加载。
  • New Chat Startup Check:进入 new chat 或新项目会话时,先检查可见的项目/系统提示词入口是否存在、是否包含本 skill 路由;缺失时询问用户是否需要新建或补充默认 prompt 文件。若用户拒绝或任务很急,继续当前任务但不静默写配置。
  • 控制方式不是预设每一步,而是在关键节点设闸:Restate、Recap Checkpoint、Approval、Validation、Reverse Sync。
  • Recap Checkpoint 是比 spec 更轻的持久化上下文:用 1-6 行记录“当前目标 / 已完成 / 关键决策 / 当前边界 / 下一步 / 验证风险”,防止长对话和暂停后的上下文腐烂;它不替代 spec,只负责让当前 loop 不断知道“我在哪”。
  • Spec 受众分层与上下文保护:Spec 的第一受众是人类(持久化的任务上下文与组织记忆),第二受众才是模型。协议对模型的核心价值是四件事:注意力聚焦(让模型只关注当前该关注的)、信息索引(需要时按路径回读,而非全量常驻)、防止上下文腐烂(用落盘的 Spec 对抗长对话中的遗忘与漂移)、辅助 Review(提供 Spec vs 代码的交叉验证基准)。协议绝不应导致上下文被塞满挤爆——RIPER 管流程,Spec 管记录,模型按需取用。
  • Project Sync Boundary:项目级规则和知识入口由项目 AGENTS.md 或用户定义。SDD 只在 Reverse Sync / Review / handoff / new chat / debug 收尾时识别 Project Sync Candidate,按已定义落点同步;未定义时先提出候选和建议,等待用户确认。详细边界按需读取 references/project-sync-boundary.md。
  • 隐私提交边界:系统级知识、Feature Spec、handoff、Project Spec / Project Memory 和用户偏好可能包含隐私或内部信息。可以主动识别、总结、提出候选,但默认不得暂存或提交到仓库;只有用户明确要求提交,且内容已按目标仓库脱敏确认后,才允许纳入 git。

硬约束

  • Spec is Truth:spec 是持久化上下文、压缩记忆与协作真相源。
  • No Spec, No Code:未形成或更新最小 spec 前,不进入代码实现。
  • Spec Boundary:普通任务默认落 Feature Spec;项目级长期事实只作为已确认的 Project Sync Candidate,按项目 AGENTS.md 或用户定义的落点同步。
  • No Approval, No Execute:未得到明确执行许可,不进入实现或高影响变更。
  • Restate First:用户输入任务后,先用模型自己的话复述理解,再进入 spec 或计划。
  • Core Goal as Loop Anchor:阶段性核心目标是当前 loop 的唯一锚点;进入执行前、发生偏差后、完成验证时,都必须重新对齐该锚点。
  • Recap Checkpoint:长任务、暂停返回、执行前、阶段收尾或用户问“现在到哪了”时,输出并按需落盘一段短 recap;它应比 spec 短得多,但必须包含下一步和验证/风险。
  • Minimal Chaos Sanity Check:只做轻量 sanity check。若任务明显太大、边界明显不清或风险明显升高,提醒用户并建议升级 deep 或切到 sdd-riper-one;否则默认相信用户拆分。
  • Checkpoint Before Execute:实现前必须给一次短 checkpoint,确认理解、目标、下一步、风险与验证方式。
  • Done by Evidence:完成应由验证结果与外部反馈证明,而不是由模型自行宣布。
  • Reverse Sync:执行后必须把结果、偏差、验证结论回写 spec。
  • Project Sync Scan:任务收尾、new chat、handoff、用户反复纠正或发现稳定项目事实时,主动扫描是否有 Project Sync Candidate;没有也要说明无可同步长期知识。
  • Resume Ready:长任务或暂停前,应在 spec 中留下最小恢复锚点,支持重启与交接;用户触发 new chat / handoff / resume pack 时,调用 $new-chat-ready 生成落盘交接包和可直接粘贴的续接 prompt。

默认假设

  • 强模型默认自行分解任务,不强制展开冗长 Research / Innovate / Plan / Execute / Review 文本。
  • 用户默认已经完成主要任务拆分;light 只辅助检查,不替用户重新拆任务。
  • 默认 prompt 文档只放最小路由和边界,不复制完整 skill,避免污染长期上下文。
  • 小任务不为了协议而拆;大任务也不为了仪式感写长计划。
  • 真正必须保留的,是最小 spec、先复述理解、recap checkpoint、执行前 checkpoint、明确批准、执行后回写。
  • 默认不反复喂 spec;checkpoint 时先让模型自总结当前目标、进度、风险和验证状态,再按需回读当前相关 spec 区块。
  • 如果任务还没重到需要完整 spec,recap checkpoint 可以作为临时上下文锚点;一旦进入多文件实现、跨轮恢复或需要验收证据,应把 recap 回写到 micro-spec / spec / handoff。
  • 如果长对话后行为漂移、忘记 spec/checkpoint/validation、新 chat 继续旧任务、或用户质疑 skill 是否生效,按需回读 references/anti-context-decay-lite.md 和 references/skill-injection-check.md。

任务深度

zero(零 Spec 通道)
  • 适用于纯机械性改动(typo 修复、日志添加、配置值变更等无决策性的单点修改)
  • 跳过 micro-spec,直接执行并在完成后用一句话 summary 回写
  • 一旦发现复杂度超出预期,立即升级到 fast 或 standard
fast
  • 先写 micro-spec,不裸改。
  • 用 1-3 句写清目标、涉及文件、主要风险、验证方式。
  • 用户明确批准后再执行。
  • 复杂度上升时升级到 standard 或 deep。
Show full SKILL.md (153 more words)Show less
standard
  • 默认模式,适用于大多数 2+ 文件改动、一般功能开发、普通缺陷修复。
  • 补齐必要上下文,维护一份轻量 spec 并落盘。
  • 执行前给一次短 checkpoint,获批后实施并回写结论。
deep
  • 适用于需求模糊、架构改动、未知根因、跨模块/跨项目、长链路迭代。
  • 允许显式分析、方案比较、风险说明,但仍保持短。
  • 先把深思考结果写回 spec,再给用户审阅;获批后再进入实现。
  • 按需加载 references/modules.md,而不是把深流程常驻。
  • 如果 deep 中需要主动拆分最小混沌单元、生成完整 codemap/context、频繁阻塞和训练用户,建议切到 sdd-riper-one。

最小工作流

  • 用户给出任务后,先复述模型自己的理解,确保核心目标强一致。
  • 轻量确认任务是否明显不是最小混沌单元;若没有明显问题,直接进入最小 spec 和 checkpoint。
  • 用最小 spec 固化目标、边界、事实、计划与结论,并尽快落盘。
  • 在 spec 中用 1-3 行写清 Done Contract:什么算完成、由什么证明、哪些情况算仍未完成。
  • 实现前给一次短 checkpoint:当前理解、核心目标、recap、下一步 1-3 个动作、风险、验证方式。
  • 若测试、日志、人工反馈暴露出偏差,先基于外部证据重述“当前核心目标是否变化、还差什么”,再决定继续执行还是调整方案。
  • 用户明确批准后执行;若范围或方案变化,先更新 spec 再重新请求批准。
  • 执行后回写 Change Log / Validation / Resume or Handoff,并说明“当前核心目标是否已由证据证明完成;若未完成,下一轮核心目标是什么”。
  • 收尾时做一次 Project Sync Boundary 检查:本次过程留在 Feature Spec;稳定、可复用、跨任务会再次影响判断的事实列为 Project Sync Candidate,并按项目已定义落点或用户确认同步。

何时暂停

遇到以下情况,先暂停并说明原因:

  • 需求存在会改变实现方向的关键歧义。
  • 需要破坏性、高风险、不可逆操作。
  • 任务明显不是最小混沌单元,且继续执行会导致大范围漂移。
  • 模型提出的路径明显越过用户给定边界。
  • 连续验证失败后仍沿同一路径推进,缺少回炉判断。
  • 涉及架构级改动、公共接口变更、数据模型变更、迁移策略变更。
  • 涉及跨项目修改,而用户未明确允许或范围未清楚。
  • 发现现有 spec 明显错误、过期或与代码现实冲突。
  • 尚未形成最小 spec 或尚未得到明确执行许可。

按需模块

  • references/spec-lite-template.md:最小 spec 模板。
  • references/routing-map.md:场景到 reference/script 的文档地图;不确定读什么时先看它。
  • references/mode-selection-lite.md:light/one 选择、升级/降级条件。
  • references/anti-context-decay-lite.md:长对话、新 chat、skill 遗忘时的回读和恢复规则。
  • references/project-sync-boundary.md:项目知识沉淀、Project Sync Candidate、AGENTS / PROJECT_KNOWLEDGE / PROJECT_MEMORY / PROJECT_SPEC / Feature Spec 分流不清时读取。
  • references/skill-injection-check.md:检查 agent / 项目规则 / 默认 prompt 是否实际注入本 skill。
  • references/default-prompt-setup-lite.md:建立项目级/系统级默认 prompt 文档的最小写法。
  • references/script-map.md:可直接调用的脚本入口,包含默认 prompt 检查/写入脚本。
  • references/modules.md:Deep Planning / Debug / Review / Multi-project。
  • references/conventions.md:落盘目录、命名规则、micro-spec 与正式 spec 的分流规则。
  • $new-chat-ready:跨对话交接能力;触发 new chat / 换对话 / handoff / resume pack / 上下文压缩时使用,light 只维护 spec 锚点,不内嵌交接模板。

输出风格

  • 默认中文,但不强制;用户、项目或目标文档明确使用其他语言时,跟随更具体的语言要求。
  • 默认短输出,不复述完整协议。
  • 优先给“当前理解 + 核心目标 + recap checkpoint + 下一步 + 必要风险”;只有不确定或需要证据时才补相关 spec 锚点。
  • 不强制打印阶段状态机。
  • 核心目标采用“事件触发式复述”:阶段开始、执行前 checkpoint、偏差暴露后、阶段收尾时必须重对齐;其他轮次不机械复读。
  • 需要长链路推进时,优先给最小 Done Contract 与 Resume/Handoff,而不是扩写长计划。
  • 小任务用 micro-spec + micro-summary;复杂任务再按需展开。
