What is maestro CLAUDE.md?

A set of development instructions for Maestro, a command-line tool that manages Git worktrees—separate working folders for different branches. It documents the project, required commands, testing, building, and code-quality checks.

Use it when working on Maestro to build, develop, test, type-check, lint, format, or run end-to-end tests with pnpm.

It gives coding agents the project’s expected workflow and prevents them from using the wrong package manager or skipping required checks. It also explains how to run individual tests.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03926	$0.03926
Opus 5.5	$0.01570	$0.01570
Sonnet 5.5	$0.00785	$0.00785
Haiku 4.5	$0.00393	$0.00393

Security

Grade A, and why

maestro CLAUDE.md 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 1mo 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.

Project Overview

Maestro is a CLI tool for managing Git worktrees with a conductor/orchestra theme. It helps developers work on multiple branches in parallel by creating "orchestra members" (worktrees) with integration for Claude Code, tmux, GitHub, and more.

Development Commands

IMPORTANT: This project uses pnpm exclusively. All commands must use pnpm instead of npm.

Build & Test

pnpm build - Build the TypeScript project using tsup
pnpm dev - Watch mode development using tsx
pnpm test - Run tests with vitest
pnpm test:e2e - Run end-to-end tests
pnpm test:coverage - Run tests with coverage report (80% minimum threshold)
pnpm typecheck - Type checking without emitting files

Code Quality

pnpm lint - ESLint checking on TypeScript files
pnpm lint:ci - CI-specific linting with max 26 warnings threshold
pnpm format - Format code with Prettier
pnpm prettier:check - Check code formatting

Single Test Execution

pnpm test -- path/to/test.test.ts - Run a specific test file
pnpm test -- --reporter=verbose - Run tests with detailed output

Publishing

pnpm changeset - Create a changeset for releases
pnpm version - Version bump using changesets
pnpm release - Build and publish to npm
pnpm prepublishOnly - Pre-publish hook (auto-build and generate completions)

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.
