High-performance reinforcement learning framework optimized for speed and scale. Use when you need fast parallel training, vectorized environments, multi-agent systems, or integration with game environments (Atari, Procgen, NetHack). Achieves 2-10x speedups over standard implementations. For quick prototyping or standard algorithm implementations with extensive documentation, use stable-baselines3 instead.
Generate and verify web scraper scripts using Actionbook's verified selectors. Auto-validates generated scripts and fixes errors.
Initialize and manage the evidence collection directory for professional security audits with documented proof of findings.
Implements Syncfusion Flutter Calendar (SfCalendar) and Date Range Picker (SfDateRangePicker) widgets for date and scheduling UIs in Flutter apps. Use when building appointment calendars, booking systems, date range selectors, or event scheduling interfaces. This skill covers calendar views, recurring events, date navigation, localization, callbacks, and customization.
Implements Syncfusion Flutter Slider controls (SfSlider, SfRangeSlider, SfRangeSelector) for numeric value selection and range inputs. Use when working with single-value sliders, range selection, or chart-range controllers in Flutter apps. This skill covers thumb and tooltip customization, ticks, dividers, RTL support, drag modes, and chart integrations.
Browser automation powers web testing, scraping, and AI agent interactions. The difference between a flaky script and a reliable system comes down to understanding selectors, waiting strategies, and anti-detection patterns. This skill covers Playwright (recommended) and Puppeteer, with patterns for testing, scraping, and agentic browser control. Key insight: Playwright won the framework war. Unless you need Puppeteer's stealth ecosystem or are Chrome-only, Playwright is the better choice in 202
A-share financial data toolkit. Provides scripts to obtain real-time A-share market quotes, financial indicators, share increases/reductions by directors, supervisors and senior executives, northbound capital flows, and macroeconomic data (LPR, CPI/PPI, PMI, social financing, M2). Used when real-time A-share market data is required to support investment analysis. All data sources are free and no API key is required.
Add, enrich, and manage contacts in Joel's Vault. Fire the Inngest enrichment pipeline for full multi-source dossiers, or create quick contacts manually. Use when: 'add a contact', 'enrich this person', 'who is X', 'VIP contact', 'update contact', or any task involving the Vault/Contacts directory.
Generates image prompts for Seedream 5.0/4.0 (Jimeng AI), and can call the API to generate images and automatically download them to the output/ directory. Workflow: describe your idea → the agent outputs a prompt for review → user confirms → the agent runs generate.py. It covers text-to-image, image editing, multi-image fusion, character consistency, knowledge cards, posters, PPT backgrounds, e-commerce images, avatars, and group/storyboard generation. Activate this tool when the user mentions terms like seedream, jimeng, AI image generation, text-to-image, image-to-image, seedream prompt, prompt keyword, one-click image generation, knowledge card, poster design, e-commerce image, character consistency, or image generation.
Compliance expert for snyk-agent-scan — the agent skill file scanner — NOT for other Snyk CLI tools (snyk test, snyk code SAST, snyk iac, snyk container). Fixes alerts through content restructuring, never by suppressing or deleting information. Covers every file in a skill directory: SKILL.md, references/, assets/, and any secondary markdown. Apply when authoring a new skill, editing an existing one, triaging a failed snyk-agent-scan run locally or in CI, or unblocking a PR held by agent scanner failures. Not applicable to dependency vulnerabilities, code security findings, or infrastructure misconfigurations — those are out of scope.
Build a brand tone of voice guide (TONE.md) via discovery, voice definition, and channel modulation. Outputs voice attributes with do's/don'ts, NN/g positioning, tone modulation matrix, lexicon, mechanics, and channel rules — consumed by downstream content skills writing on-brand copy. Covers B2B SaaS, B2C/D2C, NGO, public sector, consulting, industrial, product-led, personal, and volunteering brands; researches uncovered contexts (politics, regulated niches, religious orgs, gaming) on demand. Also adapts an existing TONE.md to a new channel (blog → LinkedIn, web → Twitter/X, in-product UI). Optionally consumes SOUL.md to pre-fill brand identity. Apply when the user wants to create a TONE.md, define brand voice, port voice to a new channel, refresh an outdated voice, or set up a content factory writing across many supports. Not for writing individual posts, articles, emails, or UI strings (→ dedicated writing skills), nor SOUL.md, PROSE.md, DESIGN.md.

Supports multiple providers (OpenAI, Anthropic, Google), 500+ integrations, ReAct agents, tool calling, memory management, and vector store retrieval. Use for building chatbots, question-answering systems, autonomous agents, or RAG applications. Best for rapid prototyping and production deployments.
