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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.02579 |
| Opus 5 | $0.00000 | $0.01290 |
| Sonnet 5 | $0.00000 | $0.00516 |
| Haiku 4.5 | $0.00000 | $0.00258 |
Grade A, and why
code-style 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 — 376 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Import Patterns
Always Use Relative Paths for Internal Imports
- CRITICAL: Never use
src/aliases for internal imports - Always use relative paths like
../../stores/blog/blog.store.js - Use package imports only for external dependencies
- Store files follow pattern:
store-name.store.ts
// ✅ CORRECT - Relative paths for internal imports
import { BlogStore } from '../../stores/blog/blog.store.js'
import { getBlogByIdUsecase } from './usecase.js'
// ✅ CORRECT - Package imports for external dependencies
import { BlogPost, BlogPostId } from '@t6c/blog-domain'
import { Effect as E } from 'effect'
// ❌ WRONG - Never use src/ aliases
import { BlogStore } from 'src/stores/blog/blog.store.js'
Comments and Documentation
Avoid Obvious Comments
- NEVER add comments that just repeat what the code is doing
- Only add comments for complex business logic that needs explanation
- Use JSDoc for public APIs, not inline comments for obvious operations
// ✅ CORRECT - No obvious comments, code is self-explanatory
const generatedData = yield* generateBlogPostData(patches)
const updates = createBlogPostPatches(patches, generatedData)
const uniqueSlug = yield* findUniqueSlug(generatedData.slug)
// ❌ WRONG - Obvious comments that add no value
// Generate comprehensive blog post data using AI
const generatedData = yield* generateBlogPostData(patches)
// Create complete patches with generated data
const updates = createBlogPostPatches(patches, generatedData)
// Ensure slug uniqueness
const uniqueSlug = yield* findUniqueSlug(generatedData.slug)
When to Use Comments
- Complex business logic that isn't obvious from function names
- Non-obvious workarounds or edge cases
- Important context that affects future changes
- Never for operations that are clear from function/variable names
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.

code-style is a cursor rule published in the GitHub repository CharLEE-X/effect-cursor-rules (6 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,579 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.
