pip install zerodep # install the CLI
zerodep add yaml retry # copy modules into your project

from yaml import load, dump
data = load("name: Alice\nage: 30")
print(data) # {'name': 'Alice', 'age': 30}

Each module is a self-contained single .py file — copy it into your project and import. No pip install needed at runtime.

Modules span Agent Protocols, Web & Networking, Data Formats, Data Validation, Text & Markup, Search & Retrieval, Configuration, CLI & Terminal, Security, and Infrastructure & Tools.

See the full module list for details, versions, and benchmarks.

• Project: CalVer YYYY.M.D (e.g., 2026年4月15日)
• Modules: independent SemVer per module (e.g., 0.4.1)

Releases are automated via the Release workflow — lint, test, bump module versions, tag, and create a GitHub Release in one step.
