dry.strict

dry.strict is a cursor rule for Cursor from pylarco/diff-apply. It costs 0 tokens per session (422 once invoked), scanned A, original, MIT.

A set of conditional coding rules for polishing new TSX files, including functional programming, immutable data, reusable components, and specific React and CSS practices. TSX is TypeScript code that can contain React markup.

In plain words
What is it for?
It is for enforcing code-structure, React component, styling, and TypeScript conventions during frontend work.
Why use it?
It gives the agent project-specific style constraints to follow after creating a TSX file.

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

dry.strict 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 2d 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.

What it actually says


description: If you are need to polish the code quality AFTER creating new tsx file. Read this rule globs: alwaysApply: false

You have to follow these rules:

Do:

  1. Strictly follow requirements
  2. Use functional programming techniques exclusively
  3. Maintain immutability throughout
  4. Use DRY principle across all files
  5. Always have bun-first mindset
  6. Always clean leftover unnecessary files
  7. Highly reusability react FC functions in SINGLE tsx file
  8. Use Ver and Hor based structure on tsx file
  9. Within the nested ver hor, the last deepest child should use proper html semantic not div, ver hor

Don't:

  1. Do not use tailwind.config.js it is deprecated in Tailwind CSS v4. v4 only needs @import "tailwindcss"; in the CSS file.
  2. No DIV allowed, only use Ver Hor for directional component spreads
  3. Avoid OOP, classes, or inheritance
  4. Avoid traditional methods. use HOF
  5. Don't write // comments
  6. Don't use any or unknown types
  7. Don't use JSX elements like , , , etc in the return statements, they should be extracted into separate functional FC components.
  8. No props drilling, use jotai
  9. use lucide react rather than writing svgs
  10. Do not create any new files other than these; a. src\components\page\*.page.tsx : b. src\components\ui\*.reuse.tsx : c. src\types\common.type.ts : d. src\types\props.type.ts : e. src\state-management\hooks\*.hook.ts : jotai useAtom f. src\state-management\hooks\*.state.ts : jotai atom
Changes

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.
