clean-code

clean-code is a cursor rule for Cursor from btseee/clean-code-skills. It costs 965 tokens per session, scanned A, original, MIT.

A set of language-independent rules for writing, editing, reviewing, testing, and refactoring code. Clean code means code organised to be understandable, focused, and maintainable.

In plain words
What is it for?
Use it as project-wide guidance during coding tasks, reviews, tests, refactors, and new-project setup. It covers responsibilities, file placement, design decisions, and verification.
Why use it?
It gives coding agents a consistent process for reading project context, respecting existing architecture, keeping changes focused, and checking that work is complete.

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 21d ago.

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

Clean Code Rules (clean-code-skills)

Non-negotiable for all code work.

Read the skill before non-trivial work. First existing path wins: .claude/skills/clean-code/SKILL.md, .agents/skills/clean-code/SKILL.md, .github/skills/clean-code/SKILL.md, skills/clean-code/SKILL.md. Then your stack's packs, named by the skill's scripts/detect_stack.py or references/framework-map.md.

Load project context first. If present: .clean/context.json, .clean/architecture.md, .clean/decisions.md, .clean/ledger.md, .clean/structure.md rows for your area; then project instruction files. Recorded decisions are settled. Project instructions outrank this block.

Work Loop

  1. Frame: behavior change, design-relevant assumptions, smallest scope, success check.
  2. Read first: nearby code, naming, tests, error style, framework idioms; search for existing implementations.
  3. Place: owning unit; which side of which boundary.
  4. Edit surgically: smallest diff, targeted edits (no whole-file regeneration), nothing unrelated; remove what your change orphaned.
  5. Verify: narrowest meaningful check, broader as risk demands.
  6. Review the diff against these rules, missing tests included.

Layers

  • Undeclared layers (.clean/architecture.md): follow framework pack's idiomatic structure.
  • Declared: Dependency Rule strict; source dependencies point inward, to higher-level policy; nothing inner names anything outer (class, function, variable, annotation, data format).
  • Business rules highest; database, web, UI, framework are details behind policy-owned interfaces.
  • SQL stays in data access; rows, ORM types, framework request/response objects never travel inward. Never derive business objects from framework base classes or annotate them; dependency-injection wiring in main.
  • Component graph acyclic; no speculative boundary, layer, or service.

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.
