What it does
Clean General is an agent skill from ertugrul-dmr/clean-code-skills. Use when writing, fixing, editing, or reviewing Python code quality. Enforces Clean Code's core principles—DRY, single responsibility, clear intent, no magic numbers, proper abstractions.
Its SKILL.md is about 670 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. It works with Python. The licence is MIT.
When your agent uses it
- Reviewing Python code quality
- Tasks that involve Code quality
Example prompts
- “/clean-general”
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 General loads about 666 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 106 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). 106 words, ~666 tokens.

General Clean Code Principles
Critical Rules
G5: DRY (Don't Repeat Yourself)
Every piece of knowledge has one authoritative representation.
# Bad - duplication
tax_rate = 0.0825
ca_total = subtotal * 1.0825
ny_total = subtotal * 1.07
# Good - single source of truth
TAX_RATES = {"CA": 0.0825, "NY": 0.07}
def calculate_total(subtotal: float, state: str) -> float:
return subtotal * (1 + TAX_RATES[state])G16: No Obscured Intent
Don't be clever. Be clear.
# Bad - what does this do?
return (x & 0x0F) << 4 | (y & 0x0F)
# Good - obvious intent
return pack_coordinates(x, y)G23: Prefer Polymorphism to If/Else
# Bad - will grow forever
def calculate_pay(employee):
if employee.type == "SALARIED":
return employee.salary
elif employee.type == "HOURLY":
return employee.hours * employee.rate
elif employee.type == "COMMISSIONED":
return employee.base + employee.commission
# Good - open/closed principle
class SalariedEmployee:
def calculate_pay(self): return self.salary
class HourlyEmployee:
def calculate_pay(self): return self.hours * self.rate
class CommissionedEmployee:
def calculate_pay(self): return self.base + self.commissionG25: Replace Magic Numbers with Named Constants
# Bad
if elapsed_time > 86400:
...
# Good
SECONDS_PER_DAY = 86400
if elapsed_time > SECONDS_PER_DAY:
...G30: Functions Should Do One Thing
If you can extract another function, your function does more than one thing.
G36: Law of Demeter (Avoid Train Wrecks)
# Bad - reaching through multiple objects
output_dir = context.options.scratch_dir.absolute_path
# Good - one dot
output_dir = context.get_scratch_dir()Enforcement Checklist
When reviewing AI-generated code, verify:
- No duplication (G5)
- Clear intent, no magic numbers (G16, G25)
- Polymorphism over conditionals (G23)
- Functions do one thing (G30)
- No Law of Demeter violations (G36)
- Boundary conditions handled (G3)
- Dead code removed (G9)
