What it does
Clean Functions is an agent skill from ertugrul-dmr/clean-code-skills. Use when writing, fixing, editing, or refactoring Python functions. Enforces Clean Code principles—maximum 3 arguments, single responsibility, no flag parameters.
Its SKILL.md is about 450 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 Code quality and Refactoring. It works with Python. The licence is MIT.
When your agent uses it
- Refactoring Python functions
- Tasks that involve Code quality
- Tasks that involve Refactoring
Example prompts
- “/clean-functions”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 1b6b3cc. 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 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 no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Clean Functions loads about 450 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 69 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
The full file from ertugrul-dmr/clean-code-skills at commit 1b6b3cc, republished under its MIT licence (© ertugrul-dmr). 69 words, ~450 tokens.

Clean Functions
F1: Too Many Arguments (Maximum 3)
# Bad - too many parameters
def create_user(name, email, age, country, timezone, language, newsletter):
...
# Good - use a dataclass or dict
@dataclass
class UserData:
name: str
email: str
age: int
country: str
timezone: str
language: str
newsletter: bool
def create_user(data: UserData):
...More than 3 arguments means your function is doing too much or needs a data structure.
F2: No Output Arguments
Don't modify arguments as side effects. Return values instead.
# Bad - modifies argument
def append_footer(report: Report) -> None:
report.append("\n---\nGenerated by System")
# Good - returns new value
def with_footer(report: Report) -> Report:
return report + "\n---\nGenerated by System"F3: No Flag Arguments
Boolean flags mean your function does at least two things.
# Bad - function does two different things
def render(is_test: bool):
if is_test:
render_test_page()
else:
render_production_page()
# Good - split into two functions
def render_test_page(): ...
def render_production_page(): ...F4: Delete Dead Functions
If it's not called, delete it. No "just in case" code. Git preserves history.
