What it does
Milestone Check is an agent skill from KATO-Hiro/AtCoderClans. Detect users who newly crossed a rating threshold (2000/2400/2800/3200) in a given AtCoder contest, validate whether they are listed on the site's blog pages, and report candidates for addition. Does not modify any files.
Its SKILL.md is about 170 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `crossers.py` and `instructions.md`).
It sits in Product & Project Management, covering Project management. It works with C++, Python and Rust. The repository describes itself as: 【非公式】AtCoderがもっと楽しくなるリンク集です。有志による非公式サービス・ツール・ライブラリ・記事などをまとめています。 The licence is MIT.
When your agent uses it
- Tasks that involve Project management
Example prompts
- “/milestone-check”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 485953d. 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 script files (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
Milestone Check loads about 166 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 40 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.
