ryan-brosas Bundle

Use when porting or reimplementing a push-mark/pull-verify signals runtime, a batched effect scheduler (microtask flush with synchronous escape), lazy derived caching with version counters, concurrent "time-travelling" async batches, a linked-list effect tree with pause/resume branch semantics, or the consumption planes over them — prop accessor factories with spread/rest proxies, store-to-signal subscription bridges, await-block flatten/context-save suspension, derived-owned effect freeze/unfreeze, and keyed-each single-pass reconciliation — as proven by svelte's client runtime (`packages/svelte/src/internal/client/{reactivity,runtime.js,dom/blocks}`). Source code and direct tests are ground truth; references carry decisive excerpts and graph retrieval.

ryan-brosas Bundle

ryan-brosas Bundle

Use when porting smolagents' code-action agent loop, AST Python sandbox, remote execution sandboxes, or minimal-agent ReAct patterns.

ryan-brosas Bundle

Use when porting daisyUI's Tailwind-plugin machinery — plugin entry registries with include/exclude algebra, theme injection ladder over CSS-variable tokens, cascade-layer specificity ladders, hand-rolled CSS selector prefix scanning, responsive breakpoint-variant generation, and the wrapper-sandwich Tailwind compile-and-extract API.

ryan-brosas Bundle

Use when porting Tailwind CSS v4 compiler mechanics — the `compile()`/`compileAst()` incremental build kernel, `@theme` design-system ingestion and resolution, candidate parsing/compilation and its deterministic sort ladder, or the variant application protocol — into another utility-CSS engine or a host integration (Vite/PostCSS/CLI driver). Source code and direct tests are ground truth; references carry decisive excerpts and graph retrieval.

ryan-brosas Skill

Use when authoring or reviewing Android apps, ribot/xmartlabs resource naming, component factories, Java/Kotlin conventions, MVP/Jetpack layering, and lint/detekt/tests in CI.
