At a glance

  • SKILL.md covers Overview, Available Puzzle Types, Get a Puzzle and Render Puzzle, plus 2 more sections
  • Runs JavaScript and Python scripts from its folder

What it does

Sudoku is an agent skill from sundial-org/awesome-openclaw-skills. Fetch Sudoku puzzles and store them as JSON in the workspace; render images on demand; reveal solutions later.

Its SKILL.md is about 650 tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including scripts and reference files (for example `README.md`, `references/DATA_FORMAT.md` and `scripts/encode_lz.js`).

The repository describes itself as: Top OpenClaw skills, with the most popular and useful ones.

Example prompts

  • “/sudoku”

Requirements

  • Python 3
  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit b80cde2. 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 7 files in scripts/ (JavaScript and Python), which the agent can run.

    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

Sudoku loads about 646 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 29 tokens; SKILL.md has 246 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~29
When it runs · the whole SKILL.md, loaded when a task matches
~646
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.1k

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 246 words (~646 tokens).

“Fetch, render, and reveal Sudoku puzzles. Use sudoku.py to get new puzzles from sudokuonline.io, generate printable PDFs or images, and reveal solutions.”
