grasp

grasp is a skill for Claude Code, Codex from renky1025/agent-skills. It costs 149 tokens per session (2,121 once invoked), scanned A, original, MIT.

A guided learning workflow for understanding a topic deeply. It explains the topic in plain language, breaks it into ten kinds of questions, and uses recall and review exercises to reinforce learning.

In plain words
What is it for?
Use it for requests such as learning a topic quickly, building a study guide, or creating a learning roadmap. It can cover definitions, structure, uses, conditions, history, future trends, risks, recall, and next steps.
Why use it?
It gives structure to unfamiliar subjects instead of stopping at a short explanation. It also checks what you can explain yourself and identifies areas that need more study.

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

grasp 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 1mo 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.

Grasp — 十维认知框架 × 加速学习协议

Purpose

把任意主题压缩成可复述、可复习、可继续深入的认知资产。以十维认知框架(名称/类别/定义/特征/组成/作用/条件/历程/前景/风险)为内容骨架,嵌入 Feynman 讲解、第一性原理拆解、主动回忆和间隔重复四种学习技术,产出知识地图 + 维度诊断矩阵 + 分阶段路线图。

When to Use

  • 用户要系统吃透一个陌生主题或领域,而不是要一个孤立事实。
  • 用户已有基础,想检测盲区或规划进阶路线。
  • 用户要一份可复习的知识地图或学习路线图。
  • 触发词:/grasp <topic>、grasp、速通、拆解、吃透、掌握、学习路线图、study guide、learn fast、master [topic]、Feynman technique、active recall。
  • 需要路由时:--phase=N 表示运行到第 N 阶段后停止。

When NOT to Use

  • 用户只需要一个快速事实 -> 直接回答,不启动协议。
  • 纯操作技能 / 肌肉记忆(需要练习而非认知框架)-> 交给练习设计,本技能不适用。
  • 用户明确只要某一维度的信息 -> 直接回答该维度,不跑全协议。
  • 用户要"把一件事给外行讲明白"的图文教学页 -> 交给 teach-eli5。
  • 用户要设计正式课程、教学大纲或教案 -> 交给 curriculum-design。

Workflow

七阶段顺序执行。每阶段结束时输出签退问题,用户确认后进入下一阶段;每阶段的完整引导问题与产出格式见 references/ten-dimensions.md。

  1. Identity(维度 1-4) — 用 Feynman 方式讲解名称、类别、定义、特征(避免术语、使用类比),随后要求用户 teach-back,标出准确 / 遗漏 / 混淆点。
  2. Anatomy(维度 5-6) — 拆解组成与结构(列组件、绘关系、分核心与辅助、展示因果链),分析核心功能与作用机制,用第一性原理验证(去掉某核心组件会怎样)。
  3. Ecosystem(维度 7-8) — 用"生存条件"框架分析必要条件 / 理想条件 / 失效条件 / 互操作条件;构建含至少 3 个转折点的时间线,做驱动力与遗产分析。
  4. Horizon(维度 9-10) — 研判当前阶段(萌芽/增长/成熟/衰退)与 2-3 条发展方向,按内在局限 / 实践瓶颈 / 社会伦理 / 失败模式四类审查风险,做一次批判性反问(做空论证)。
  5. Recall(全 10 维) — 脱离资料,逐维提问(难度递增),生成维度诊断矩阵并路由补救。
  6. Map(全 10 维) — 将十维成果压缩为一页知识地图,并制定间隔重复计划。
  7. Path(全 10 维) — 评估当前水平,输出分阶段路线图 + 资源推荐 + 一条可立即执行的下一步。

Decision Rules

  • 用户给 --phase=N -> 只运行到第 N 阶段并停止(--phase=5 直接跳到全维度诊断,--phase=6 只出知识地图,--phase=7 只出路线图)。
  • 用户未指定 -> 从 Phase 1 完整走完 1-7。
  • 用户目标含糊或无明显基础 -> 先跑 Phase 1,不要跳过身份层。
  • Phase 5 诊断出问题 -> 按类型路由:
问题类型 路由
概念混淆、关系缺失 回到对应 Phase 重新讲解
信息不足 记入 Phase 7 学习路线图
记忆消退 纳入 Phase 6 间隔重复
推理错误 回到 Phase 2 用第一性原理重新推导
  • 需要某阶段的引导问题或提问模板 -> 读 references/ten-dimensions.md。
  • 需要知识地图 / 路线图的逐字模板 -> 读 references/deliverable-templates.md。
  • 用户追问为什么这样学、或需要复习排期 -> 读 references/learning-techniques.md。

Constraints

  • 十维覆盖是底线:每个 Phase 明确标注覆盖维度,不得遗漏。
  • 方法服务于维度:Feynman、第一性原理是手段,不是独立阶段。
  • Phase 1-4 必须按认知深度递进,不得平铺。
  • 不得编造事实、来源或数字;信息不足时标注"信息不足"并记入路线图,而不是填充内容。
  • 讲授语言跟随用户;术语首次出现必须就地解释。

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

grasp is a skill published in the GitHub repository renky1025/agent-skills (11 stars, last pushed 15d ago), licensed MIT. It adds 149 tokens to every session and 2,121 once invoked, about $0.0006 per session on Opus 5.5. 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.
