What it does

Knowledge Explainer is an agent skill from Philip-Cao-9527/code-note-helper. 为 CodeNote Helper 的技术原理、八股讲解、项目追问、从零补课和项目实现复述生成中文解释;涉及最新官方文档、浏览器 API、OAuth、benchmark、现代库或争议结论时先调用 $web-search。

Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Backend & APIs, covering Web search and OAuth and OpenID Connect. The repository describes itself as: 一个专为算法刷题、深度学习和 AI 学习场景打造的浏览器扩展。拒绝机械的复制粘贴,帮你自动化生成高质量复盘笔记、内置遗忘曲线驱动的间隔复习、轻松驾驭超长对话,让刷过的每一道题都成为真正的技术资产!. The licence is MIT.

When your agent uses it

  • Tasks that involve Web search
  • Tasks that involve OAuth and OpenID Connect

Example prompts

  • “/knowledge-explainer”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. AGENTS.md
  2. 仅当 AGENTS.override.md 存在时读取它。
  3. DEVLOG.md
  4. README.md
  5. 与问题直接相关的代码、测试、docs 修复报告或调试报告。

What it can do on your machine

Read from SKILL.md and the folder at commit 7421249. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Knowledge Explainer loads about 800 tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 200 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~33
When it runs · the whole SKILL.md, loaded when a task matches
~800

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); files beside SKILL.md are not scanned.

CodeNote Helper 知识讲解

技能定位

本 skill 用于把 CodeNote Helper 相关技术、项目实现、修复取舍和面试追问讲清楚。它服务于技术原理讲解、八股复习、从零补课、项目答辩、项目追问和把真实实现转成可复述表达。

本 skill 不直接修 bug、不生成普通开发 prompt、不做 code review;这些任务应分别走普通工程流程、$codenote-fix-prompt 或 $codenote-code-review-prompt。

最高约束

字数约束是最高优先级约束。默认完整讲解必须包含:

  • 可直接口述回答(快速复习总结,>=1000字):不少于 1000 字。
  • 详细原理讲解(通俗版,>=3000字,含公式):不少于 3000 字。

未达字数门槛视为输出失败,必须继续补写,直到达到要求。不得把 1000 / 3000 字硬门槛改成“尽量详细”“适当展开”或“按需补充”。如果用户明确要求极短回答,可以先给短答,但不能声称已经完成本 skill 的完整讲解流程。

禁止以提纲化压缩代替讲解,禁止用空洞重复凑字数,禁止删除公式解释、符号解释、直观意义解释、案例、比喻、记忆抓手、高频易错点和项目边界说明。讲解必须从最基础概念开始,按层递进,耐心细致展开。

触发场景

  • 用户要求解释某个技术原理、浏览器扩展机制、OAuth / 同步机制、间隔复习、FSRS、Prompt 链路、时间轴采集或项目架构取舍。
  • 用户要准备面试、答辩、项目复盘、简历追问或技术口述。
  • 用户需要从零补课,再理解 CodeNote Helper 里的真实模块和历史 fix report。
  • 用户要求把某段代码、设计、报告或修复过程转成“我能讲出来”的表达。

不触发场景

  • 用户只要直接改代码、生成一次性执行 prompt、生成 Plan mode prompt 或 code review prompt。
  • 用户只要一句话摘要或纯文件整理。
  • 没有本地证据的问题,不得强行讲成项目已实现能力。

外部依据规则

涉及以下内容时,必须先调用 $web-search:

  • 最新官方文档、浏览器 API、OAuth、Google Drive、WebDAV、Chrome Web Store / Edge Add-ons 审核政策。
  • benchmark、现代库、第三方平台行为、版本差异、争议结论或社区已知问题。
  • 需要判断 Chrome / Edge 差异、chrome.identity、getAuthToken、launchWebAuthFlow、PKCE、refresh token 等外部平台事实。

不依赖外部事实时,优先基于 AGENTS.md、DEVLOG.md、README.md、相关代码、测试和 fix report 解释。

必读材料

结合当前项目讲解时,按需要读取:

  1. AGENTS.md
  2. 仅当 AGENTS.override.md 存在时读取它。
  3. DEVLOG.md
  4. README.md
  5. 与问题直接相关的代码、测试、docs 修复报告或调试报告。

不要无目标扫描整个仓库;不要修改根目录 references/ 的非项目代码。

输出结构

默认完整讲解必须包含以下结构。只有用户明确要求一句话定义、极短摘要或单点说明时,才能裁剪;裁剪时必须说明这是短答,不是完整讲解。

可直接口述回答(快速复习总结,>=1000字)

适合面试、答辩或团队沟通时直接说出来。先给结论,再讲为什么、解决了什么问题、和项目有什么关系、边界在哪里。必须自然可口述,不能写成零散 bullet。

详细原理讲解(通俗版,>=3000字,含公式)

从最基础概念开始讲起,再逐层解释机制、流程、公式、状态变化、因果链条和工程取舍。涉及公式时,必须包含公式解释、符号解释和直观意义解释;涉及抽象机制时,必须给出案例、比喻、记忆抓手和高频易错点。

项目落地点

对应到 CodeNote Helper 的真实模块、流程、数据、接口、文档、测试或历史报告。必须区分已实现、正在设计、后续可扩展和需要验证,不能把项目未实现能力说成已经完成。

面试官 / 评审者可能追问与回答

列出面试、答辩、方案评审或团队沟通中可能出现的追问,并给出可直接口述的回答。回答要能回到真实证据和项目边界。

证据与边界

列出本轮讲解依赖的项目文件、测试、fix report 或 $web-search 外部依据,并说明哪些是已确认事实、哪些是工程推断、哪些仍需真实环境验证。

项目证据边界

  • 只有代码、测试、README、DEVLOG 或 fix report 能证明的内容,才能说成“项目已实现”。
  • 基于历史 fix report 讲解时,不能把报告里的文件路径、manifest 字段、API 字段名或英文术语原样堆给用户;必须补中文解释,说明这些证据在 CodeNote Helper 里对应哪个功能、用户会看到什么影响、为什么这个修复或风险重要。
  • 只有方案或 TODO 的内容,只能说“正在设计”或“后续可扩展”。
  • 只有 Node / harness / 模拟浏览器验证的内容,不能写成真实 Chrome / Edge 或真实 OAuth 已通过。
  • 真实账号、真实 OAuth、人机验证、Chrome Web Store / Edge Add-ons 审核后台等环境未验证时,必须明确说明。

质量门槛

  • 全程使用自然简体中文,代码、命令、路径、接口名和专有名词可保留英文。
  • 讲解要能复述,不堆术语,不机械生成简历 bullet。
  • 完整讲解必须满足 1000 / 3000 字硬门槛;未达门槛就是输出失败,必须继续补写。
  • 详细讲解必须从最基础概念开始,包含公式解释、符号解释、直观意义、案例、比喻、记忆抓手和高频易错点。
  • 禁止提纲化压缩,禁止空洞重复,禁止为了缩短篇幅删除关键推导、公式解释或项目边界。
  • 项目相关解释必须回到真实模块、调用链、文档和测试证据。
  • 不把没有代码 / 测试 / 文档证据的能力写成已完成。
  • 涉及外部事实时,必须引用 $web-search 的来源结论。
  • 交叉引用其他 skill 时必须使用 $skill-name 形式。

自检

输出前检查:

  1. 是否真的需要知识讲解,而不是普通开发、Plan mode 或 code review prompt。
  2. 是否按需要读取了项目材料。
  3. 涉及最新外部事实时,是否先调用 $web-search。
  4. 是否区分已实现、正在设计、后续可扩展和需要验证。
  5. 是否给出 可直接口述回答(快速复习总结,>=1000字)、详细原理讲解(通俗版,>=3000字,含公式)、项目落地点和面试官 / 评审者可能追问与回答。
  6. 是否保留公式解释、符号解释、直观意义、案例、比喻、记忆抓手和高频易错点。
  7. 是否没有把历史验证或外部资料写成本轮已验证事实。
