mgriot Skill

Design robust, scalable, production-ready database schemas for SQL and NoSQL databases. Use this skill whenever the user mentions designing a schema, creating tables, modeling data, database architecture, normalization, indexing, migrations, or anything about structuring a database — even if they don't use the word "schema". Trigger on phrases like "I need a database for...", "how should I store...", "what tables do I need...", "help me model...", "design my data model", or any request to think through how to persist data. Covers normalization (1NF–3NF), indexing strategies, constraint design, foreign key patterns, soft deletes, audit trails, multi-tenancy, migration patterns, and performance optimization.

Trigger on requests for `.d2` files, mentions of `d2`/`d2lang`, or open-ended diagramming tasks ("draw me a system diagram", "make a flowchart of X", "diagram the request flow", "give me an ER diagram for these tables"). Covers the full DSL — shapes, connections, containers, classes, vars, globs/filters, imports, layers/scenarios/steps, styling, themes, sketch mode, icons, markdown/LaTeX/code blocks, layout engines, CLI flags, and the specialized diagram shapes.

When the user wants to plan, design, or implement an A/B test or experiment. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," or "hypothesis." For tracking implementation, see analytics-tracking.

packmindhub Bundle

Review an implemented GitHub issue the way a senior Packmind engineer would — the human-judgment checks that ESLint, the TypeScript compiler, and e2e tests cannot catch (authorization scoping, hexagonal-architecture conformance, analytics-event wiring, UX copy, UI reactivity, CLI behavior, multi-tenancy safety, and more). Use this skill once an issue has been implemented and you have a diff to inspect — before opening or merging the PR. Trigger on 'review this implementation', 'engineer review', 'packmind review', 'QC this issue', 'is this issue done well', 'review issue #NNN', or any post-implementation quality gate. Reach for it even when the user just says the work is done and asks 'anything I missed?' — automated checks already ran; this is the layer they don't cover.
