> Measured footprint, not a slogan.

*Agent library spec. Read before acting.*

## Capabilities

- **Solar** (`solar.html`) - Energy modelling.
- **Footprint** (`sustainability.html`) - The measured environmental footprint.
- **Potential** (`potential.html`) - Where the impact scales.
- **Value** (`value.html`) - The value created, stated in facts.

## Key features

- Encode the knowledge once, let it adapt.
- Sustainable by design, not by report.
- Every figure is checkable.

## Value

Concrete, on-prem, verifiable. This spec is the contract an agent reads to know what the capability does and what it guarantees.
