What it does

Error Analysis is an agent skill from mingchen666/Reviva. This skill should be used when the user asks to "分析错题", "错因分析", "整理错题本", "我这道题做错了", "帮我分析错因", "归类薄弱知识点", "错误模式", "巩固练习", "这道题怎么错了", "为什么做错了", "帮我看看这道题", "我的答案和标准答案不一样", "老师说我这题错了", "这几道题都错了帮我看看", "我总是这类题错", or when the user submits wrong answers, homework corrections, marked papers, screenshots of mistakes, or wants error pattern analysis and targeted consolidation exercises.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including reference files (for example `config.json`, `examples/batch-error-case.md` and `examples/pattern-detected-case.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

  • The user submits wrong answers
  • Homework corrections
  • Screenshots of mistakes
  • Wants error pattern analysis and targeted consolidation exercises

Example prompts

  • “我这道题做错了”
  • “帮我分析错因”
  • “归类薄弱知识点”
  • “/error-analysis”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Glob, Grep, Bash

Workflow steps

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

  1. 先用 Read 读取所有相关文件
  2. 以用户提供的材料为主要参考
  3. 使用材料中的术语、公式、定义和评分标准
  4. 不编造答案、评分规则、老师批注或材料内容
  5. 材料不完整或有歧义时明确说明
  6. 用户的答案在另一种解释下可能成立时,说明这种可能性

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:

    • Read
    • Write
    • Glob
    • Grep
    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    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

Error Analysis loads about 1.6k tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 98 tokens; SKILL.md has 328 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~98
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.5k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Write, Glob, Grep, Bash

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 328 words (~1,630 tokens).
