react-rerender-auditor
by handxr
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.

"Systematic improvement of existing agents through performance analysis, prompt engineering, and continuous iteration."
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.
wandb-experiment-memory
by wilfred-dore
Query Weights & Biases experiment history to retrieve past optimization runs, compare configurations, and inform the next optimization decision. Use this skill when asked to review past AI optimization experiments, find the best configuration tried so far, understand what has already been explored, or suggest the next experiment to run based on W&B history.
javascript-best-practices
by jcastillotx
JavaScript coding standards and best practices. This skill should be used when writing, reviewing, or refactoring JavaScript code. Triggers on tasks involving vanilla JavaScript, DOM manipulation, async operations, or performance optimization.
timeline-skill
by tower1229
Factual timeline layer. Given a time range, retrieves or generates structured episode facts from memory and session history. Returns a TimelineWindow JSON object. Writes new episodes to disk (Append-Only).

by Olino3
Intelligent Jest unit test generation for Angular components, services, and more with Socratic planning and project-specific memory.
cost-optimization
by TriNgo0108
Optimize cloud costs through resource rightsizing, tagging strategies, reserved instances, and spending analysis. Use when reducing cloud expenses, analyzing infrastructure costs, or implementing cost governance policies.
data-quality
by masterkram
Diagnose and fix data quality problems in datasets. Use when working with dirty data, finding duplicates, handling missing values, detecting outliers/anomalies, validating constraints (functional dependencies, referential integrity), profiling datasets, or cleaning data for analysis or ML. Covers the full data quality lifecycle - define, detect, clean, measure.
web-perf-ux
by october-academy
Web application performance and UX optimization through automated analysis. Use when developers need to (1) measure and diagnose performance issues using Lighthouse and Core Web Vitals, (2) identify root causes of LCP, CLS, INP problems, (3) analyze UX pain points like layout shifts or slow interactivity, (4) generate actionable improvement plans with concrete code-level fixes. Triggers on requests like "analyze performance", "why is my page slow", "fix CLS issues", "optimize web vitals", "run Lighthouse", "performance audit", or "improve page speed".
character-profile-generator
by BizShuk
This skill generates detailed virtual character profiles based on a standardized template. Use this skill when a user wants to create or refine a character for stories, roleplay, or virtual assistants. It guides the user through a clarifying dialogue to establish core personality, behavior, and background before generating the final profile.
