What it does
Clean Code is an agent skill from xenitV1/Antigravity-Workflows. Pragmatic coding standards - concise, direct, no over-engineering, no unnecessary comments
Its SKILL.md is about 1.6k 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 Code simplification. The licence is MIT.
When your agent uses it
- Tasks that involve Code quality
- Tasks that involve Code simplification
Example prompts
- “/clean-code”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Write, Edit
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Run the script and capture ALL output
- Parse the output - identify errors, warnings, and passes
- Summarize to user in this format
- Wait for user confirmation before fixing
- After fixing → Re-run script to confirm
What it can do on your machine
Read from SKILL.md and the folder at commit f0a1fa7. 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:
ReadWriteEdit
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
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 Code loads about 1.6k tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 582 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.

Core Principles
| Principle | Rule |
|---|---|
| SRP | Single Responsibility - each function/class does ONE thing |
| DRY | Don't Repeat Yourself - extract duplicates, reuse |
| KISS | Keep It Simple - simplest solution that works |
| YAGNI | You Aren't Gonna Need It - don't build unused features |
| Boy Scout | Leave code cleaner than you found it |
Naming Rules
| Element | Convention |
|---|---|
| Variables | Reveal intent: userCount not n |
| Functions | Verb + noun: getUserById() not user() |
| Booleans | Question form: isActive, hasPermission, canEdit |
| Constants | SCREAMING_SNAKE: MAX_RETRY_COUNT |
Rule: If you need a comment to explain a name, rename it.
Function Rules
| Rule | Description |
|---|---|
| Small | Max 20 lines, ideally 5-10 |
| One Thing | Does one thing, does it well |
| One Level | One level of abstraction per function |
| Few Args | Max 3 arguments, prefer 0-2 |
| No Side Effects | Don't mutate inputs unexpectedly |
Code Structure
| Pattern | Apply |
|---|---|
| Guard Clauses | Early returns for edge cases |
| Flat > Nested | Avoid deep nesting (max 2 levels) |
| Composition | Small functions composed together |
| Colocation | Keep related code close |
AI Coding Style
| Situation | Action |
|---|---|
| User asks for feature | Write it directly |
| User reports bug | Fix it, don't explain |
| No clear requirement | Ask, don't assume |
Anti-Patterns (DON'T)
| ❌ Pattern | ✅ Fix |
|---|---|
| Comment every line | Delete obvious comments |
| Helper for one-liner | Inline the code |
| Factory for 2 objects | Direct instantiation |
| utils.ts with 1 function | Put code where used |
| "First we import..." | Just write code |
| Deep nesting | Guard clauses |
| Magic numbers | Named constants |
| God functions | Split by responsibility |
🔴 Before Editing ANY File (THINK FIRST!)
Before changing a file, ask yourself:
| Question | Why |
|---|---|
| What imports this file? | They might break |
| What does this file import? | Interface changes |
| What tests cover this? | Tests might fail |
| Is this a shared component? | Multiple places affected |
Quick Check:
File to edit: UserService.ts
└── Who imports this? → UserController.ts, AuthController.ts
└── Do they need changes too? → Check function signatures🔴 Rule: Edit the file + all dependent files in the SAME task. 🔴 Never leave broken imports or missing updates.
Summary
| Do | Don't |
|---|---|
| Write code directly | Write tutorials |
| Let code self-document | Add obvious comments |
| Fix bugs immediately | Explain the fix first |
| Inline small things | Create unnecessary files |
| Name things clearly | Use abbreviations |
| Keep functions small | Write 100+ line functions |
Remember: The user wants working code, not a programming lesson.

🔴 Self-Check Before Completing (MANDATORY)
Before saying "task complete", verify:
| Check | Question |
|---|---|
| ✅ Goal met? | Did I do exactly what user asked? |
| ✅ Files edited? | Did I modify all necessary files? |
| ✅ Code works? | Did I test/verify the change? |
| ✅ No errors? | Lint and TypeScript pass? |
| ✅ Nothing forgotten? | Any edge cases missed? |
🔴 Rule: If ANY check fails, fix it before completing.
Verification Scripts (MANDATORY)
🔴 CRITICAL: Each agent runs ONLY their own skill's scripts after completing work.

❌ WRONG:
test-engineerrunningux_audit.py✅ CORRECT:frontend-specialistrunningux_audit.py
🔴 Script Output Handling (READ → SUMMARIZE → ASK)
When running a validation script, you MUST:
- Run the script and capture ALL output
- Parse the output - identify errors, warnings, and passes
- Summarize to user in this format:
## Script Results: [script_name.py]
### ❌ Errors Found (X items)
- [File:Line] Error description 1
- [File:Line] Error description 2
### ⚠️ Warnings (Y items)
- [File:Line] Warning description
### ✅ Passed (Z items)
- Check 1 passed
- Check 2 passed
**Should I fix the X errors?**- Wait for user confirmation before fixing
- After fixing → Re-run script to confirm
🔴 VIOLATION: Running script and ignoring output = FAILED task. 🔴 VIOLATION: Auto-fixing without asking = Not allowed. 🔴 Rule: Always READ output → SUMMARIZE → ASK → then fix.

Questions about Clean Code
What does Clean Code do?
Pragmatic coding standards - concise, direct, no over-engineering, no unnecessary comments. Clean Code is an agent skill from xenitV1/Antigravity-Workflows.
When should I use Clean Code?
Clean Code fits situations like: tasks that involve Code quality; tasks that involve Code simplification.
How do I install Clean Code in Claude Code?
Run `npx skills add xenitV1/Antigravity-Workflows --skill clean-code -a claude-code`. Or copy the skill folder (skills/clean-code in xenitV1/Antigravity-Workflows) into .claude/skills/clean-code in your project. Claude Code loads it when a task matches its description.
How do I install Clean Code in Codex?
Run `npx skills add xenitV1/Antigravity-Workflows --skill clean-code -a codex`. Or copy the skill folder (skills/clean-code in xenitV1/Antigravity-Workflows) into .agents/skills/clean-code in your project. Codex loads it when a task matches its description.
Can I use Clean Code in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add xenitV1/Antigravity-Workflows --skill clean-code -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/clean-code, .gemini/skills/clean-code, .github/skills/clean-code and .opencode/skills/clean-code in your project.
What does Clean Code need to run?
Going by SKILL.md and its folder, Clean Code needs the command-line tools its instructions call (python). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Write, Edit.
Does Clean Code access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Clean Code safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Clean Code use?
Clean Code is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Clean Code use?
About 1.6k tokens (SKILL.md is roughly 6.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Clean Code?
Skills that share tags, products or a category with Clean Code: Codebase Health Refactoring (kucherenko/jscpd, 6.3k stars), DRY Refactoring With jscpd (kucherenko/jscpd, 6.3k stars), Code Simplifier (keep-starknet-strange/starkzap, 108 stars) and Code Simplifier (TwiTech-LAB/devchain, 101 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
