  • Works in 2 steps: Analyze: Detect errors, identify causes,… → Tutorial: Generate step-by-step…

What it does

Screenshot Analyzer is an agent skill from minicoohei/ai-agent-camp. スクリーンショットからエラー診断や操作チュートリアルを自動生成するスキル。 「スクショを分析して」「画面のエラーを調べて」「操作手順を作って」等のリクエストで発動。

Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts (for example `SKILL.en.md`, `SKILL.es.md` and `agents/openai.yaml`).

The repository describes itself as: AI Agent Camp — non-engineer-friendly AI agent training curriculum. Lessons, skills, commands, and hooks for Claude Code, Cursor, and Codex.

Example prompts

  • “/screenshot-analyzer”

Requirements

  • Python 3
  • A credential in GEMINI_API_KEY
  • A credential in GOOGLE_API_KEY

Workflow steps

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

  1. Analyze: Detect errors, identify causes, suggest solutions
  2. Tutorial: Generate step-by-step operation guides with annotations

What it can do on your machine

Read from SKILL.md and the folder at commit 048ba4c. 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

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    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 these keys or tokens, usually read from environment variables:

    • GEMINI_API_KEY
    • GOOGLE_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Screenshot Analyzer loads about 555 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 129 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~26
When it runs · the whole SKILL.md, loaded when a task matches
~555

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); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 129 words (~555 tokens).

“Analyze screenshots for error diagnosis or operation tutorial generation.”
