clean-code

A set of practical rules for writing readable, maintainable code. It covers naming, function size and responsibilities, arguments, side effects, and basic structure.

In plain words
What is it for?
Use it during coding or review to choose clearer names, split responsibilities, reduce duplication, simplify functions, and avoid building unused features.
Why use it?
Inconsistent names, oversized functions, repeated logic, and unnecessary complexity make code harder to understand and change. These rules provide shared standards for improving it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

clean-code scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Clean Code - Pragmatic AI Coding Standards

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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

clean-code is a skill published in the GitHub repository CBEPX/talos-mcp-server (0 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 923 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
