Audit React components for unnecessary re-renders, inline object/array/function creation in JSX props, Context.Provider with unstable values, useEffect anti-patterns (async callbacks, setState loops, missing deps), expensive unmemoized render operations, and component complexity issues. Use when reviewing React performance, debugging slow components, auditing a codebase for re-render issues, or when a user asks to check their React code for performance problems, find unnecessary re-renders, optimize components, or audit hook usage. Triggers on tasks involving .jsx/.tsx/.js/.ts files with React components.
agent-builder
by YPYT1
Build high-performing OpenClaw agents end-to-end. Use when you want to design a new agent (persona + operating rules) and generate the required OpenClaw workspace files (SOUL.md, IDENTITY.md, AGENTS.md, USER.md, HEARTBEAT.md, optional MEMORY.md + memory/YYYY-MM-DD.md). Also use to iterate on an existing agent’s behavior, guardrails, autonomy model, heartbeat plan, and skill roster.
upsell-sequence-assembler
by tonyflo79
Assemble all upsell sequence pieces (order bump + upsell + downsell) into a cohesive sequence document with cross-page narrative validation. Use after U1-U3 have produced their individual pieces. This is an ASSEMBLY + VALIDATION skill, not a writing skill — it combines existing pieces, validates threading between them, verifies pricing cascade compliance, and catches inconsistencies that individual skill validations miss. Produces assembled sequence document plus E0 handoff for email integration. Trigger when users mention assembling the upsell funnel, compiling upsell pages, sequence validation, or building the complete post-purchase flow. Requires U0-U3 outputs.
