Every field's professional best practices — your expert consultant in engineering, medicine, law, finance, and more. Anywhere, anytime.
Use when the user wants to apply a practice but has specific constraints that differ from the canonical case — team size, industry regulation, budget, maturity level, technology stack, or organizational culture. Produces an adapted version that preserves the practice's core while fitting the user's reality.
Use when the user presents a problem that isn't well-defined — goal is unclear, scope is unstated, or what's described looks like a symptom rather than a root cause. Asks clarifying questions one at a time until the problem boundary is clear, then produces a problem statement, problem space map, and possible solution routes before handing off to solution skills.
Use when the user wants to systematically align any project or artifact to their stated best practice preferences — e.g., "apply BPDD", "align this project to our settings", "close the gap between our practices and reality", "enforce our best practices like TDD".
Use when the user wants to activate a named set of best practices for a paradigm or methodology — e.g., "use OOP", "set profile to clean-architecture", "apply TDD practices", "switch to functional style".
Use when a problem is too complex for a single skill but stays within one domain — match the best-fitting skill, let it decompose the problem, then recursively match sub-problems until each is covered by a best practice or resolved directly.

The official skill library for grimoire — 1000+ best practices across 27 domains, ready to load into any AI assistant.
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. This library is the enforcement layer — skills: named, citable, executable units of expert practice. One concept. One source. One set of steps.
