grasp

grasp is a skill for Claude Code, Codex from renky1025/agent-skills. It costs 92 tokens per session (4,479 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 9d 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

基于认知科学验证的7阶段交互协议,以十维认知框架为内容骨架,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。

用户调用:/grasp <topic> [--phase=N]

协议设计理念

十维认知框架(内容骨架)     ×     学习科学技术(方法引擎)
─────────────────────           ─────────────────────
维度 1-4  → Phase 1 Identity      Feynman Technique + Teach-back
维度 5-6  → Phase 2 Anatomy       第一性原理拆解
维度 7-8  → Phase 3 Ecosystem     时间线 + 条件分析
维度 9-10 → Phase 4 Horizon       情景推演 + 批判审视
全 10 维  → Phase 5 Recall        主动回忆 + 维度诊断
全 10 维  → Phase 6 Map           知识地图 + 间隔重复
全 10 维  → Phase 7 Path          进阶路线 + 行动清单

10个维度依次为:

  1. 名称和概念 2. 类别和种属 3. 含义和定义 4. 特征和属性
  2. 组成和结构 6. 作用和功能 7. 条件和环境 8. 历程与演变
  3. 前景与趋势 10. 风险与挑战

Phase 1 — Identity · 身份层(维度 1-4)

目标:建立对知识对象的基本身份认知——它叫什么、属于什么类、如何定义、有哪些区分性特征。

方法:Feynman Technique + Teach-back loop

1.1 讲解(Feynman 方式)

用通俗语言依次覆盖 4 个维度,避免术语,使用类比:

维度 引导问题 输出
名称和概念 它叫什么?如果只能用一句话解释给外行,怎么说? 一句话解释 + 常见别名/误称
类别和种属 它在知识树上属于哪个分支?上位/同位/下位概念是什么? 概念层级关系
含义和定义 标准定义是什么?不同流派/场景下含义有差异吗? 权威定义 + 语境差异
特征和属性 最关键的 3-5 个特征是什么?如何识别/衡量? 核心特征清单

1.2 Teach-back

讲解结束后,要求用户用自己的话复述:

"现在用你自己的话给我讲一遍:它是什么、属于哪一类、如何定义、有什么特征。我会指出遗漏。"

1.3 诊断

根据用户复述,标出:

  • 表达准确的部分(强化)
  • 遗漏或模糊的部分(补讲)
  • 概念混淆的部分(澄清,特别关注"类别和种属"中的易混淆概念)

签退:"Phase 1 complete. 对 [topic] 的身份特征已建立。进入解剖层? (y/n)"


Phase 2 — Anatomy · 解剖层(维度 5-6)

目标:理解知识的内部构造和外部功能——由什么构成、各部分如何协作、整体发挥什么作用。

方法:第一性原理拆解 + 功能分析

2.1 结构拆解(维度 5:组成和结构)

  1. 列出组成部分——将其拆解为不可再分的子单元
  2. 绘制关系——各组件之间的依赖、层次、时序或数据流关系
  3. 区分核心与辅助——哪些组件不可替代?哪些是可替换的?
  4. 展示一条因果链——从最基础组件出发,逐步组合,推导出完整的结构

2.2 功能分析(维度 6:作用和功能)

  1. 核心功能——它解决什么痛点 / 满足什么需求?
  2. 作用机制——输入端 → 内部过程 → 输出端,完整走通
  3. 典型场景——在哪些实际情境中发挥作用?
  4. 替代方案对比——为什么选它而不是别的?它在什么场景下是更好的选择?

2.3 第一性原理验证

"基于你看到的这些组件和它们的关系,如果把[某个核心组件]去掉或改变,会发生什么?"

引导用户从结构推导功能,而非死记硬背。

签退:"Phase 2 complete. 对 [topic] 的内部结构和工作原理已拆解。进入生态层? (y/n)"


Phase 3 — Ecosystem · 生态层(维度 7-8)

目标:理解知识存在的条件和历史脉络——它需要什��环境才能成立、从何而来、经历了哪些关键演变。

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 (10 stars, last pushed 10d ago), licensed MIT. It adds 92 tokens to every session and 4,479 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.
