How does the skill detect the correct package manager?

The skill scans the project root for specific lock files such as bun.lock, pnpm-lock.yaml, yarn.lock, or package-lock.json to determine the preferred package manager.

Does it support Python environments like Poetry or UV?

Yes, it recognizes various Python setups including Poetry, Pipenv, UV, and standard venv, with specialized support for Poe the Poet tasks.

Is the detection process run every time a command is executed?

No, the detection results are stored in a marathon state file after the first run. Subsequent commands use the cached results for better performance.

Which programming languages are currently supported?

The skill provides built-in detection logic for Node.js, Python, Go, Rust, and Java projects.

Can this skill handle complex monorepo structures?

Absolutely. It detects Turborepo, Nx, Lerna, and native pnpm/npm workspaces, providing the correct filtering syntax for workspace-specific commands.

Developer Tools

Identifies project stacks, package managers, and monorepo configurations to provide standardized development and build commands.

The Project Detection skill streamlines development workflows by automatically identifying a project's technical architecture, including its programming language, package manager, and monorepo structure. By scanning for specific configuration files like package.json, turbo.json, or pyproject.toml, it generates a normalized set of commands for installation, testing, and building tailored to the specific environment. This eliminates manual configuration errors and ensures that Claude Code interacts with the codebase using the correct tools every time, leveraging a persistent state cache for high-performance execution.
