lamina-product-behavior
Define authoritative runtime product truth across actors and views. Use when modeling domain behavior, setting product density, specifying side effects, protecting invariants, choosing consistency guarantees, handling retries or concurrent actions, defining time semantics and prerequisites, drawing ownership boundaries, or keeping views coherent. Use lamina-systems for causal loops and change over time, and lamina-ux for interaction expression.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Lamina Product Behavior ## Reference-loading protocol 1. Match the request's primary runtime-truth decision to one row below. 2. Open that linked reference before answering. Add another only when a second decision materially changes the answer; do not preload the directory. 3. Start the response with `Using lamina-product-behavior: <topic path(s)>` so the selected behavior lens is auditable. ##
What does the lamina-product-behavior skill do?
Define authoritative runtime product truth across actors and views. Use when modeling domain behavior, setting product density, specifying side effects, protecting invariants, choosing consistency guarantees, handling retries or concurrent actions, defining time semantics and prerequisites, drawing ownership boundaries, or keeping views coherent. Use lamina-systems for causal loops and change over time, and lamina-ux for interaction expression.
How do I install it?
Run `npx skills add aryaniyaps/lamina --skill lamina-product-behavior --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From aryaniyaps/lamina, a repository with 111 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
