| Listing | Kind | What it does |
| --- | --- | --- |
| [TypeScript Type Safety](/app/wrdn-typescript-type-safety) | Skill | Someone silenced type checking for a whole file to get past something, and it stayed silenced. This takes those bypasses out. Reach for it… |
| [Package Boundaries](/app/wrdn-package-boundaries) | Skill | In a workspace with several packages, it is easy to reach into a neighbour with a relative path, and the packages quietly stop being separa… |
| [Effect Atom Reactivity Keys](/app/wrdn-effect-atom-reactivity-keys) | Skill | Sometimes you save a change and the screen keeps showing the old data, because nothing told it to refresh. When the linter points at a writ… |
| [Effect Vitest Tests](/app/wrdn-effect-vitest-tests) | Skill | A test that passes sometimes and fails other times is worse than no test, and assertions hidden behind an if are a common cause. This tidie… |
| [Effect Value Inferred Types](/app/wrdn-effect-value-inferred-types) | Skill | You build an object and hand it back, then write a separate type spelling out the same thing, and now edits have to land in both. This take… |

| [Effect Client Wrapper Pattern](/app/effect-client-wrapper) | Skill | You are writing with Effect and need to call a library that was not built for it, like a payments or email SDK. This is a repeatable patter… |
| [Effect Typed Errors](/app/wrdn-effect-typed-errors) | Skill | Errors that are just thrown and caught tell you very little, and by the time you handle one you often do not know what it is. This converts… |
| [Graphite CLI Command Reference](/app/graphite) | Skill | If your team keeps branches stacked on top of each other, the plain git commands get awkward fast. This handles the everyday moves - commit… |
