code-style

A set of TypeScript code-style rules for the T6C project, which uses Effect-TS, a TypeScript library for structuring programs. It covers internal imports, file naming, comments, and documentation.

In plain words
What is it for?
Use it when writing or reviewing T6C TypeScript files, especially when choosing import paths, naming store files, or documenting public code.
Why use it?
It keeps code consistent and avoids confusing import paths or comments that merely restate the code.

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.

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

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.

T6C Effect-TS Code Style Guide

Guidelines for code style in the T6C project using Effect-TS architecture.

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.
