fritzprix Skill

Audit React Context usage, detect prop drilling, verify compound component patterns. Use when reviewing frontend code for proper Context consumption, checking AgentChatContext/AgentSessionContext usage, or enforcing compound component patterns.

fritzprix Bundle

Guide for implementing smooth, native-feeling animations using React's View Transition API (`<ViewTransition>` component, `addTransitionType`, and CSS view transition pseudo-elements). Use this skill whenever the user wants to add page transitions, animate route changes, create shared element animations, animate enter/exit of components, animate list reorder, implement directional (forward/back) navigation animations, or integrate view transitions in Next.js. Also use when the user mentions view transitions, `startViewTransition`, `ViewTransition`, transition types, or asks about animating between UI states in React without third-party animation libraries.

fritzprix Bundle

Code recipes and explanation for synchronizing Rust backend pending tool approvals (YOLO mode/manual approval) to the frontend React UI when a user resumes or opens an existing agent session. Use this skill when modifying the AgentSession state to maintain approval channels or when fixing UI bugs related to missing pending tool executions upon page reload/session switch.

fritzprix Bundle

Refactor oversized source files into smaller, coherent modules while reducing complexity and preserving behavior. Use when Claude needs to split a large component, hook, service, command handler, or Rust module; untangle mixed responsibilities; extract helpers or submodules; or reorganize code into a clearer modular design without changing the public contract.

ninjasln-labs Skill

Run the quality verification chain—5 abstract verification layers (domain logic / contract / component interaction / E2E user journeys / visual regression) mapped onto the project's own test stack (unit runner, type checker, contract tests, e2e suite, visual regression), each with a gate, plus a run-all delivery gate and a DoD quality gate (deterministic assertions + probabilistic sample/threshold for model-driven behavior). Use when delivering or verifying a feature, before claiming work complete, or when asked to run full self-tests / quality checks. NOT for: stage-level DoD aggregation (use stage-gate) or single-shot verification (use verification-before-completion).

ninjasln-labs Skill
