Why Contribute Open Skills?

Reusable calculation logic

You contribute a Python script that takes JSON in and returns JSON out. Reviewers run the tests. The desk and agents call the same module later — you do not have to learn the rest of the runtime.

Public methods, not trade secrets

Skills encode public methodologies: NREL's LCOE formula, EPA emission factors, GHG Protocol calculations. This is procedural knowledge, not trade secrets.

Tests and examples ship with it

A merged skill includes fixtures a reviewer can replay. The same calculation runs every time the module is invoked — not a one-off notebook.

“Stop building bespoke agents for every task. Build reusable Skills that any agent can invoke. Code is the universal interface.”

— Skills-First Architecture Philosophy

How to Contribute

Choose a Skill Gap

Review the skills inventory below and pick one marked as 'needed' that matches your expertise.

Follow the Template

Use the lcoe-calculator as your reference implementation. Copy the folder structure and adapt it.

Write Python Scripts

Implement your calculation using only Python standard library. Accept JSON input, output JSON.

Add Tests & Examples

Include test cases and example inputs so others can validate and learn from your work.

Submit a Pull Request

Open a PR to the greencio repository. Maintainers review and integrate accepted skills.
