Use when conducting a formal assessment of a project, facility, or operation's impacts on ecosystems, biodiversity, and natural resources.
Use when calculating personal or organizational ecological footprint in global hectares — applying the Global Footprint Network methodology to quantify land and sea area required to sustain resource consumption and absorb waste, and identify the highest-impact categories for reduction.
Use when planning a field biodiversity monitoring survey — designing sampling strategy, site selection, species identification methods, and data recording protocols to produce repeatable, statistically valid biodiversity assessments.
Use when assessing a building, facility, or organization's energy use to identify waste, prioritize efficiency improvements, and establish a baseline for reduction targets.
Use when developing a systematic plan to reduce energy consumption, improve energy performance, and achieve measurable efficiency targets for a facility, organization, or portfolio.

The world's knowledge is in your AI. The world's practice is not.
Most people don't know which best practice applies — and AI won't enforce one unless guided. Grimoire closes both gaps.
"We're launching our SaaS in 48 hours. I'm terrified something will break. What do we do?"

Not an engineer? See Skills in Action for law, finance, cooking, and health examples — same idea, different domain.
Your AI knows everything — Grimoire makes it practice it.
Books gave everyone knowledge. Google gave everyone access. AI gave everyone comprehension. None of them gave everyone practice. Grimoire does.
The model knows SOLID, DDD, Google SRE, and the ABA Model Rules. Without explicit guidance, it enforces none of them. Grimoire is the enforcement layer — skills: named, citable, executable units of expert practice, one concept, one source, one set of steps.
If you've spent 10,000 hours mastering something, your practice belongs here.
