Manages Python package dependencies. Use when adding, upgrading, removing, or syncing Python/pypi packages in projects or libs.

Build AI agents on Cloudflare Workers using the Agents SDK. Load when creating stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, chat applications, voice agents, or browser automation. Covers Agent class, state management, callable RPC, Workflows, durable execution, queues, retries, observability, and React hooks. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.

Create and execute load tests for performance validation using k6, JMeter, and Artillery. Use when validating application performance under load conditions or identifying bottlenecks. Trigger with phrases like "run load test", "create stress test", or "validate performance under load".

Convert text to speech using ElevenLabs voice AI. Use when generating audio from text, creating voiceovers, building voice apps, or synthesizing speech in 70+ languages.

Profiles, reduces frontend/backend costs: split bundles, optimize assets, apply caching, fix Core Web Vitals regressions. Use when profiling Lighthouse/CI regressions, reducing bundle size, or fixing high CLS/LCP/TTI metrics.

Execute use when you need to work with Docker Compose. This skill provides Docker Compose file generation with comprehensive guidance and automation. Trigger with phrases like "generate docker-compose", "create compose file", or "configure multi-container app".

Use when writing unit/integration tests for Vite projects - configure vitest.config.ts, write test suites with describe/it, create mock implementations with vi.fn and vi.mock, set up code coverage thresholds, and run tests in parallel

Optimizes images for web performance using modern formats, responsive techniques, and lazy loading strategies. Use when improving page load times, implementing responsive images, or preparing assets for production deployment.

This skill should be used when building React components with TypeScript, typing hooks, handling events, or when React TypeScript, React 19, Server Components are mentioned. Covers type-safe patterns for React 18-19 including generic components, proper event typing, and routing integration (TanStack Router, React Router).

Optimizes API performance through payload reduction, caching strategies, and compression techniques. Use when improving API response times, reducing bandwidth usage, or implementing efficient caching.

Creates comprehensive API changelogs documenting breaking changes, deprecations, and migration strategies for API consumers. Use when managing API versions, communicating breaking changes, or creating upgrade guides.

This skill should be used when building React components with TypeScript, typing hooks, handling events, or when React TypeScript, React 19, Server Components are mentioned. Covers type-safe patterns for React 18-19 including generic components, proper event typing, and routing integration (TanStack Router, React Router).

Enforces fresh verification evidence before any completion or success claims. Use when about to say "done", "fixed", "tests pass", "build succeeds", or any synonym; before committing, creating PRs, or moving to the next task; before expressing satisfaction or positive statements about work state; and after agent delegation to independently verify results. Prevents unverified claims by requiring command execution, output inspection, and exit code confirmation.

Query Obsidian vaults via obi CLI. Use for any vault data lookup instead of grep or find -- searching notes, filtering by frontmatter (read status, type, tags), listing folders, reading sections, checking backlinks, and finding unread or recent notes.

Extract text, tables, and structured data from documents using prebuilt and custom models.

Use when writing unit/integration tests for Vite projects - configure vitest.config.ts, write test suites with describe/it, create mock implementations with vi.fn and vi.mock, set up code coverage thresholds, and run tests in parallel

Extract text, tables, and structured data from documents using prebuilt and custom models.

Starts and controls the reaper MITM proxy to capture, inspect, search, and replay HTTP/HTTPS traffic between clients and servers. Capabilities include starting/stopping the proxy scoped to specific domains, viewing captured request/response logs, searching traffic by method/path/status/host, and inspecting full raw HTTP entries for security analysis. Use when the user asks to "start the proxy", "capture traffic", "intercept requests", "inspect HTTP traffic", "search captured requests", or "view request/response".
