What it does
Mistake Analyzer is an agent skill from mingchen666/Reviva. Analyze incorrect answers from text, documents, or images; identify root causes of mistakes; classify error types; explain correct reasoning; and generate targeted improvement suggestions, wrong-question notebook entries, or similar practice questions. Use when the user provides a wrong answer, asks why they were wrong, uploads a marked question, or wants help reviewing mistakes.
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `config.json`).
It sits in Education, covering Root cause analysis. 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 provides a wrong answer
- Asks why they were wrong
- Uploads a marked question
- Wants help reviewing mistakes
Example prompts
- “/mistake-analyzer”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Inspect the image before analyzing.
- Extract visible information
- Clearly separate
- Do not guess unreadable handwriting, symbols, formulas, or diagrams.
- Ask for a clearer image or typed text if critical information is unclear.
- Pay special attention to
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 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 (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
Mistake Analyzer loads about 2.7k tokens when it runs. Until then it costs about 100 tokens; SKILL.md has 1,027 words of instructions outside code blocks.
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 1,027 words (~2,665 tokens).
“This skill helps the agent analyze mistakes in learning and assessment contexts.”
