Domain Modeling
Model the business language before modeling storage, APIs, or implementation.
Context
Domain modeling turns reviewed requirements into a stable business-language contract. Its job is to reduce ambiguity before later phases lock in schema, API, or implementation decisions.
In Prodcraft, this skill is most valuable when:
- the same noun may mean different things to product, operations, and engineering
- brownfield work must preserve legacy terms without letting them silently define the new model
- downstream skills need to know which concepts are authoritative, derived, transitional, or still unresolved
This is not database design, API design, or task planning. Stay at the domain layer.
Inputs
- requirements-doc -- produced by the preceding skill in the lifecycle

system-design
Use when reviewed requirements or specifications are ready and the team must decide high-level architecture, component boundaries, integration seams, or brownfield coexistence strategy before API design, technology selection, or task planning.
6ci-cd
Use when a reviewed implementation slice needs an automated build, test, and deployment pipeline, especially when brownfield rollback, release-boundary checks, contract/integration gates, and staged delivery must be explicit before shipping.
6intake
The mandatory gateway for all new engineering work. Triage and route new products, apps, features, migrations, tech-debt, or any 'not sure where to start' request to the correct lifecycle path. Use before starting design or implementation. Do not use for ongoing tasks, specific debugging, or PR reviews.
6feature-development
Use when a reviewed task slice has tests or acceptance targets and the team must turn it into a small, mergeable implementation increment without expanding scope, breaking contracts, or hiding release-boundary risk.
6monitoring-observability
Use when a live service or newly delivered release needs actionable telemetry, dashboards, and alerts that expose real user-impactful boundaries, especially when brownfield coexistence rules, unsupported-flow safety, rollback health, or queue/backfill behavior must be visible before incidents escalate.
6incident-response
Use when a live production issue needs coordinated containment, severity triage, stakeholder communication, and evidence capture, especially when a recent release, brownfield coexistence rules, rollback decisions, or unresolved contract boundaries must be handled before root-cause work.
