/build-contract-first-integrations
Build contract-first integrations
Treat system boundaries as contracts so product code does not guess what another layer accepts or returns.
Reusable AI skills for product engineering.
These are language-neutral skills distilled from real product-engineering work. Three are free to use in full; the paid skills and complete collection are available through Forcir.
Free skills
The three open skills cover the foundations: design tokens, contract-first integrations, and URL-addressable UI state.
Interface systems/Free
/standardize-ui-with-design-tokens
Standardize UI with design tokens
Use shared visual foundations without letting components borrow meaning from each other.
Frontend architecture/Free
/sync-ui-state-with-urls
Sync UI state with URLs
Give important UI states durable URLs so navigation, sharing, refresh, and mobile layouts stay coherent.

/sync-search-filters-with-urls
Represent search state so people can share, restore, and understand it without depending on hidden UI memory.
Quality systems/Paid/$39
/test-role-based-user-workflows
Test the paths people actually rely on, not only whether the build can compile.
