Cloudflare Introduces a Faster TypeScript Compiler Written in Rust
Cloudflare introduces tsrs, a Rust port of TypeScript’s compiler promising faster checks and lower memory use, with the TypeScript team’s help.
LEEWAY™ — Logically Enhanced Engineering Web Architecture Yield. A lightweight autonomous code governance SDK that embeds identity, safety, readability, and repair assistance directly into the developer workflow.
LEEWAY™ (Logically Enhanced Engineering Web Architecture Yield) is a software development standard that transforms codebases into self-describing, auditable, AI-readable systems.
The LEEWAY SDK is a lightweight agent platform that embeds governance, safety, readability, and repair assistance directly into the developer workflow — without requiring a heavy LLM runtime.
npm install leeway-sdk
npx leeway doctor
npm install github:4citeB4U/LeeWay-Standards#main
npx leeway doctor
npx leeway audit
Traditional codebases become chaotic over time.
Files lose context. Developers leave. Documentation becomes outdated.
LEEWAY solves this by embedding identity and intent directly into the code itself.
Every file must answer five fundamental questions:
This concept is known as the 5WH Identity Model.
Every file must clearly identify itself via a LEEWAY header at the top that defines:
LEEWAY enforces a structured architecture. Files must be placed in directories that match their function.
| Directory | Region | Purpose |
|---|---|---|
src/components/ | UI | User interface components |
src/core/ | CORE | Core system logic |
src/data/ | DATA | Storage and database access |
src/ai/ | AI | AI orchestration and models |
src/seo/ | SEO | Search and discovery logic |
src/utils/ | UTIL | Utilities and helpers |
src/mcp/ | MCP | Multi-Component Processing |
src/security/ | SECURITY | Security and policies |
A LEEWAY system constantly validates itself:
Every file must begin with a LEEWAY identity header:
/*
LEEWAY HEADER — DO NOT REMOVE
REGION: UI.APP.SURFACE
TAG: UI.COMPONENT.NEXUS.BUTTON
COLOR_ONION_HEX:
NEON=#39FF14
FLUO=#0DFF94
PASTEL=#C7FFD8
ICON_ASCII:
family=lucide
glyph=layout-dashboard
5WH:
WHAT = Nexus voice control button
WHY = Primary interface for voice commands
WHO = Rapid Web Development
WHERE = src/components/NexusButton.tsx
WHEN = 2026
HOW = React + Tailwind component
AGENTS:
AZR
PHI3
GEMINI
QWEN
LLAMA

*/
Every file must include a TAG that describes its role.
Tag format: DOMAIN.SUBDOMAIN.ASSET.PURPOSE
UI.COMPONENT.NEXUS.BUTTON
AI.ORCHESTRATION.MODEL.LOADER
DATA.LOCAL.STORE.MAIN
SEO.SCHEMA.GENERATOR.JSONLD
UTIL.FORMAT.DATE.HELPER
| Context | Convention | Example |
|---|---|---|
| Folders | kebab-case | voice-engine/ |
| React Components | PascalCase | VoiceControlPanel.tsx |
| Functions/Variables | camelCase | generateSchemaMarkup() |
| Agent | Purpose |
|---|---|
assess-agent | Surveys what already exists before anything is created |
align-agent | Normalizes files, settings, and structure |
audit-agent | Scores compliance and generates reports |
| Agent | Purpose |
|---|---|
header-agent | Inserts and repairs LEEWAY headers |
tag-agent | Infers TAG values from file path and role |
region-agent | Assigns REGION correctly |
discovery-pipeline-agent | Ensures every artifact has discovery metadata |
authority-agent | Declares allowed actions and execution scope |
placement-agent | Checks file placement against structure rules |
registry-agent | Updates tag registry and system map |
| Agent | Purpose |
|---|---|
endpoint-agent | Detects existing health and HTTP endpoints |
transport-agent | Verifies approved MCP transport usage |
port-agent | Assigns and validates ports from a registry |
process-agent | Handles process ownership and zombie cleanup |
env-agent | Validates required vs optional env vars |
runtime-agent | Checks module/runtime compatibility |
manifest-agent | Validates manifest completeness and tool definitions |
health-agent-lite | Runs lightweight startup and readiness checks |
| Agent | Purpose |
|---|---|
syntax-agent | Guards against malformed code |
import-agent | Normalizes import style and local import rules |
module-policy-agent | Prevents CommonJS/ESM drift |
duplicate-logic-agent | Detects repeated logic and duplicate blocks |
dependency-graph-agent | Builds lightweight dependency maps |
circular-dependency-agent | Detects circular imports |
refactor-scan-agent | Suggests safe structural improvements |
| Agent | Purpose |
|---|---|
secret-scan-agent | Looks for secrets and unsafe credential handling |
permission-agent | Checks action permissions and runtime boundaries |
prompt-security-agent | Scans prompts for unsafe patterns |
tool-access-agent | Ensures tools are called through approved paths |
policy-agent | Enforces LEEWAY policy bundles |
privacy-agent | Checks privacy and data handling declarations |
| Agent | Purpose |
|---|---|
schema-agent | Generates machine-readable schemas |
sitemap-agent | Builds site/discovery maps |
intent-registry-agent | Tracks supported intents and routes |
docs-agent | Generates structured docs from headers |
explain-agent | Explains a file or module in plain English |
architecture-map-agent | Produces a JSON/ASCII architecture map |
| Agent | Purpose |
|---|---|
router-agent | Chooses which agents to invoke for a task |
memory-agent-lite | Stores SDK-local state and audit receipts |
doctor-agent | Runs full system health and compliance diagnosis |
import { AssessAgent, AuditAgent, DoctorAgent } from 'leeway-sdk';
// Assess the codebase
const assess = new AssessAgent({ rootDir: process.cwd() });
const inventory = await assess.run();
console.log(inventory.summary);
// Run a compliance audit
const audit = new AuditAgent({ rootDir: process.cwd() });
const report = await audit.runAndSave();
console.log(`Average compliance: ${report.summary.averageScore}/100`);
// Full system diagnosis
const doctor = new DoctorAgent({ rootDir: process.cwd() });
const diagnosis = await doctor.run();
console.log(doctor.formatReport(diagnosis));
The following rules must always be followed:
leeway scan to detect any accidental secrets before committing| Level | Score | Description |
|---|---|---|
| 🥇 Platinum | 95–100 | Fully LEEWAY-compliant |
| 🥈 Gold | 80–94 | Mostly compliant, minor gaps |
| 🥉 Silver | 60–79 | Partially compliant |
| 🔶 Bronze | 40–59 | Minimal compliance |
| ❌ None | 0–39 | Not LEEWAY-compliant |
If these rules are followed, the system will remain stable, understandable, and scalable.
