Claude Orchestrator: A System for Efficiently Decomposing and Executing Complex Tasks

tl;dr

• Created a Claude Code version of Roo Orchestrator
• Unlike Roo which doesn't support parallel tasks, Claude Code's Task can execute in parallel

Introduction

I've been a regular user of Roo Orchestrator and wanted a Claude version of it.

Orchestrator

Split complex tasks into sequential steps, where each step can contain multiple parallel subtasks.

Process

1. Initial Analysis
   • First, analyze the entire task to understand scope and requirements
   • Identify dependencies and execution order

• Plan sequential steps based on dependencies

For @alex__bit and ast-grep developpers.

I am aware that I have not yet done enough research and learning about ast-grep. But I will summarize what I have been thinking.

I am prototyping a tool called typescript-mcp that provides IDE refactoring functions using MCP. I am also developing an LSP version that is TypeScript-independent.

 * Inspired by fast-check
 * Example
 * ```ts
 * import { generate, integer, string } from "@mizchi/pbt";
 *
 * const g = generate(integer({ min: 1, max: 10 }));
 * for (const n of g(10000)) {

Playwright Test を GitHub Actions で Sharding する

https://playwright.dev/docs/test-sharding

ローカルで試す。

npx playwright test --shard=1/2 のようにすると、テスト上から(おそらくFS依存のls列挙順で) shard 数で割って分配してくれる。

$ npx playwright test --shard=1/2
