Comprehensive performance profiling, bottleneck detection, and optimization system
Detects non-functional "theater" code that appears complete but doesn't actually work. Use this skill to identify code that looks correct in static analysis but fails during execution, preventing fake implement...
Check resource usage (CPU, memory) on cluster nodes. Used to identify nodes under pressure. Keywords: node resources, cpu, memory, capacity, pressure, metrics, cluster health.
Deep investigation of a failing pod. Gathers logs, events, and resource status to identify root cause. Keywords: investigate, debug, pod failure, troubleshoot, root cause, logs, events.
Explain how components are expanded under the hood, including HasComponent and ComponentState; use when a request involves debugging or understanding generated component code in Cairo.
Guides Claude through integrating Gleam with JavaScript code using FFI, external functions, and NPM packages. Use when building for JavaScript target, using browser APIs, or wrapping JS libraries.
Explain Cairo references, snapshots (`@`), `ref` parameters, and desnap (`*`); use when a request involves borrowing, avoiding moves, or mutating data through references in Cairo.
Explain Cairo unrecoverable errors, `panic`, `panic!`, `panic_with_felt252`, `nopanic`, and `panic_with`; use when a request involves panics or panic annotations in Cairo.
Analyzes Java project structure and generates comprehensive documentation including tech stack, architecture, modules, configuration, internal SDKs, and development guidelines. Use this skill when you need to u...
Query the Intent Layer to answer questions about the codebase. Use when asking "what owns X?", "where should I put Y?", "what constraints apply to Z?", or navigating an unfamiliar codebase using its AGENTS.md h...
Vercel edge deployment specialist covering Edge Functions, Next.js optimization, preview deployments, ISR, and storage solutions. Use when deploying Next.js applications, implementing edge computing, or configu...
Use PROACTIVELY when checking if tests catch real bugs, assessing test suite quality, finding weak tests, or measuring mutation score. Validates test effectiveness beyond coverage metrics by introducing code mu...
Comprehensive performance benchmarking, regression detection, automated testing, and performance validation. Use for CI/CD quality gates, baseline comparisons, and systematic performance testing.
Use PROACTIVELY when setting up end-to-end testing, debugging UI issues, creating visual regression suites, or automating browser testing. Uses Playwright with LLM-powered visual analysis, screenshot capture, a...
Use PROACTIVELY when setting up OpenTelemetry monitoring for Claude Code usage tracking, cost analysis, or productivity metrics. Provides local PoC mode (full Docker stack with Grafana) and enterprise mode (cen...
Use PROACTIVELY when auditing code quality, running security scans, assessing technical debt, reviewing code for production readiness, setting up CI quality gates, or tracking DORA metrics. Analyzes codebases a...
Real-time performance metrics collection, bottleneck detection, SLA monitoring, anomaly detection, and resource tracking. Use for continuous system monitoring, performance dashboards, and proactive issue detect...
Use PROACTIVELY when users ask about React project structure, Bulletproof React patterns, or need architecture guidance. Covers structure setup, codebase auditing, anti-pattern detection, and feature-based migr...
Use PROACTIVELY when creating research reports, experiment writeups, technical whitepapers, or empirical study documentation. Orchestrates the complete benchmark report pipeline with structure, diagrams, hi-res...
Reviews code for bugs, security issues, and quality improvements. Use when reviewing pull requests, checking code quality, or when asked to review changes.
Extract Intent Layer content from git history. Analyzes commits, PRs, and blame to discover pitfalls, contracts, architecture decisions, and entry points that should be documented in AGENTS.md files.
Four-phase debugging framework with root cause tracing - understand the source before proposing fixes. Use when investigating bugs, errors, unexpected behavior, or failed tests.
Evidence-driven debugging for project or system issues: reproduce the bug, capture commands/logs/stack traces, narrow scope, prove root cause with concrete evidence (no guessing), apply minimal fix, and re-run...
Write JavaScript code with deep understanding of the language fundamentals as envisioned by Brendan Eich, creator of JavaScript. Emphasizes first-class functions, prototypes, and the dynamic nature of the langu...
