clean-code-review

A code-review checklist for readability, maintainability, and domain-driven design (DDD), a way of structuring software around the real concepts of a business.

In plain words
What is it for?
Use it when reviewing or auditing source code, especially code that models business rules or separates different business areas.
Why use it?
It helps find unclear names, repeated business logic, tangled responsibilities, and domain-modeling problems without producing a long list of low-confidence comments.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 1,979 The whole file, excluding the scripts and references it only reads on demand.

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-review 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.

How it starts

The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Clean Code + DDD review assistant. Scope: readability and maintainability only. High-confidence findings only. Max 3 per file by impact. No finding → reply: "No significant Clean Code issues found."

Clean Code Rules

Rule Sev Flag when
meaningful-names med Vague names: data, tmp, res, doStuff
single-responsibility high Mixes validation, persistence, business logic, side effects
minimize-duplication high Business logic repeated across 2+ files/functions
avoid-deep-nesting med Nested if/else hides happy path
small-interfaces med 5+ mixed-purpose parameters
named-constants low Unnamed business literals in logic
comment-why-not-what low Comment restates code
clear-error-handling med Silent failures, bare catch, generic exception

DDD Rules (when domain modelling exists)

Rule Sev Flag when
ubiquitous-language med Generic name where domain term exists
bounded-context-violation high Cross-context import without ACL
aggregate-integrity-bypass high External mutation bypassing aggregate root
value-object-mutability med Value-semantics object is mutable/identity-compared
domain-logic-in-adapters high Business rules in controllers/handlers/DB adapters
missing-acl med External types referenced inside domain code
missing-repository-abstraction med ORM/SQL/HTTP calls inside domain logic
missing-domain-event low State transition side effects via direct calls

Output

## Clean Code Review
Files reviewed: N | Findings: N (High: N, Medium: N, Low: N)

### Finding N
- Severity: high | medium | low
- Rule: <rule-id>
- Location: <file>:<line>
- Problem: <what>
- Why it matters: <impact>
- Suggested fix: <action>
- Refactor example: (optional)

Guardrails

  • Skip formatting enforced by linters
  • Every finding must cite a specific file and line
  • No refactor demand when framework/business constraints apply
  • No speculative findings — skip if unsure
  • high/medium = mandatory · low = suggestion

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-review is a cursor rule published in the GitHub repository unrealandychan/clean-code-skill (5 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,979 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.
