What it does

Classroom Activity Skill is an agent skill from mingchen666/Reviva. Design purposeful classroom activities, inquiry tasks, discussion prompts, questioning chains, group work, experiments, demos, warm-ups, exit tickets, peer instruction, and interactive learning checkpoints. Use this skill whenever the user asks for 课堂活动, 互动环节, 小组讨论, 探究任务, 提问链, 导入活动, 实验活动, 课堂游戏, 公开课活动, 出门条, or ways to make a lesson more engaging while staying aligned to teaching goals.

Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `config.json`, `references/activity-library.md` and `references/questioning.md`).

It sits in Education, covering Lesson planning. 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

  • The user asks for 课堂活动
  • Ways to make a lesson more engaging while staying aligned to teaching goals

Example prompts

  • “/classroom-activity-skill”

Requirements

  • Pre-approved tools (allowed-tools): file_read, file_write

Workflow steps

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

  1. Identify the learning point.
  2. Choose the activity type.
  3. Script the teacher and student moves.
  4. Add the thinking path.
  5. Add evidence and management.

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
    • file_write

    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

Classroom Activity Skill loads about 839 tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 103 tokens; SKILL.md has 372 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~103
When it runs · the whole SKILL.md, loaded when a task matches
~839
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.9k

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 372 words (~839 tokens).

“Design activities that make student thinking visible and help the teacher collect evidence during class. Do not create entertaining activities that are disconnected from the lesson objective.”
