Use when defining domain model is required during architecture work, especially when the result must be traceable, independently reviewable, and safe to hand to another agent.

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.
# Defining Domain Model ## Overview This skill owns one bounded responsibility: **defining domain model**. Its focus is defining domain model within architecture lifecycle boundaries. It converts declared inputs into typed artifacts and reproducible evidence without silently changing product scope. ## Trigger Activate only when the project is in one of these stages: `architecture`, all contract preconditions pass, and the router identifies a missing output this skill can produce. Do not activate merely because the skill name resembles the user request. ## Required Inputs - `product-definition` - `ux-contract` - Optional: `domain-blueprint` - Optional: `product-thesis` - Optional: `capability-map` - Current gate result, open findings, artifact hashes, and invalidation state - Required tools: none - Optional tools: none - Confirmed human decisions relevant to this scope ## Method-Specific Protocol 1. Define the exact decision, actors, objects, states, invariants, side effects, and non-goals owned by defining domain model. 2. Build a decision table for normal, boundary, invalid, permission, failure, retry, recovery, concurrency, migration, and abuse conditions relevant to defining dom

What does the defining-domain-model skill do?
Use when defining domain model is required during architecture work, especially when the result must be traceable, independently reviewable, and safe to hand to another agent.
How do I install it?
Run `npx skills add casioreview20-glitch/forge-os --skill defining-domain-model --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 casioreview20-glitch/forge-os, a repository with 11 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.
