What it does
Precheck is an agent skill from ayutaz/piper-plus. PR 作成前の lint + format + test 一括実行。引数で scope (python/rust/cs/go/js/cpp/all) を指定可能。未指定なら git diff から自動判定。
Its SKILL.md is about 650 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Linting and formatting. It works with Python, C++, Rust and Git. The repository describes itself as: Multilingual neural TTS (6 languages: JA/EN/ZH/ES/FR/PT, code supports SV) — C++, C, Rust, Go, Python, npm (WASM). VITS + Prosody, streaming, CUDA/CoreML/DirectML. pip install…. The licence is MIT.
When your agent uses it
- Tasks that involve Linting and formatting
Example prompts
- “/precheck”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Bash(uv run *), Bash(cargo *), Bash(dotnet *), Bash(go test *), Bash(go vet *), Bash(node *), Bash(npm *), Bash(cmake *), Bash(ctest *), Bash(git diff *), Bash(git status *)
What it can do on your machine
Read from SKILL.md and the folder at commit 9c6946e. 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:
Bash(uv run *)Bash(cargo *)Bash(dotnet *)Bash(go test *)Bash(go vet *)Bash(node *)Bash(npm *)Bash(cmake *)Bash(ctest *)Bash(git diff *)
…and 1 more on the same allowed-tools line.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
uvdotnetcargogogitnpmcmake
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, git and npm, which can reach the network depending on how they are called.
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
Precheck loads about 647 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 110 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.
