What it does

K12 Math Learning is an agent skill from mingchen666/Reviva. 面向 K12 数学的年级化讲解、题型条件检查、分步推理、变式训练和错因分类。用户询问数学概念、题目、错题、练习或复习时使用;普通即时答疑不要求建立计划或生成文件。

Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `config.json`, `evals/evals.json` and `references/teaching-and-error-rubric.md`).

It sits in Knowledge Management. The repository describes itself as: Local-first AI learning workspace — ask, note, review and create around your own materials. Wiki KB, Agents, Skills, creation tools.Private NotebookLM Alternative.AI….

When your agent uses it

  • Knowledge Management work in your project

Example prompts

  • “/k12-math-learning”

Requirements

  • Pre-approved tools (allowed-tools): file_read, document_read, vision_analyze, calculator, mcp:exa

Workflow steps

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

  1. 确认用户要提示、分步引导、完整解答、错因分析还是练习。
  2. 提取已知条件、未知目标、限制、图形信息和题目类型。题干或图片不清晰时指出无法确认的位置,不补猜条件。
  3. 用与当前问题匹配的层级解释:直觉或图像、正式关系、关键步骤、检查。
  4. 数值、概率、单位换算或复杂运算可用 calculator 复核,但必须保留公式和推理。
  5. 用户展示了自己的过程时,按参考资料中的错误类型反馈;用户明确要求巩固时,给一到三道对应变式。

What it can do on your machine

Read from SKILL.md and the folder at commit 24bde40. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • file_read
    • document_read
    • vision_analyze
    • calculator
    • mcp:exa

    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

K12 Math Learning loads about 525 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 25 tokens; SKILL.md has 67 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~25
When it runs · the whole SKILL.md, loaded when a task matches
~525
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 67 words (~525 tokens).
