Proposal Strategist transforms RFPs into persuasive win narratives through strategic positioning, compelling themes, and executive summary craft. Sales teams, proposal managers, and business development professionals use it to move beyond compliance-driven responses to buyer-centric storytelling.
A specialized agent that guides users through designing, building, and operating scalable data pipelines and lakehouse architectures. Data engineers, analytics engineers, and platform teams use this to architect reliable ETL/ELT systems and cloud data infrastructure.
Growth Hacker is an agent that helps founders and product teams rapidly acquire users through data-driven experimentation, viral loops, and conversion funnel optimization. It's useful for startups and scaling businesses seeking to identify and exploit untapped growth channels.
An AI/ML engineering expert agent that helps developers build, deploy, and integrate machine learning models into production systems with scalable, practical solutions. Ideal for engineers building intelligent features and data pipelines.
A specialized agent for building high-performance 3D rendering systems and spatial computing applications using Swift and Metal on macOS and Vision Pro. Ideal for developers creating immersive visualizations and native spatial experiences.
An embedded firmware specialist agent that helps developers design and implement production-grade firmware for resource-constrained microcontrollers across ESP32, STM32, Nordic nRF, and ARM platforms. Ideal for hardware engineers and embedded systems developers who need expert guidance on RTOS, HAL configuration, and bare-metal programming.
Cursor rules that provide AI coding agents with guidance for developing the Streamlit library itself (backend, frontend, protobufs), rather than building Streamlit applications.

When you need to use an icon, always use the Tabler icon include syntax: When linking to other pages, always use the relative page syntax: All pages are statically generated to HTML using Eleventy (11ty). Keep this in mind when:
The vocabulary you didn't know you needed. 1 skill, 20 commands, and curated anti-patterns for impeccable frontend design. Anthropic created frontend-design, a skill that guides Claude toward better UI design. Impeccable builds on that foundation with deeper expertise and more control. Every LLM lea
A Claude Code plugin that shows what's happening — context usage, active tools, running agents, and todo progress. Always visible below your input.  
Use this skill to create or update full-page screens in Figma by reusing the published design system — components, variables, and styles — rather than drawing primitives with hardcoded values. The key insight: the Figma file likely has a published design system with components, color/spacing variabl
1. Run the scaffold script: 2. Open and replace placeholders. 3. Generate or update the repo marketplace entry when the plugin should appear in Codex UI ordering:
Playwright Interactive enables fast iterative UI debugging by keeping browser and Electron instances alive in a persistent js_repl session, allowing developers to test and refine UI interactions without repeated restarts.
A skill for bootstrapping, developing, and designing modern WinUI 3 desktop applications with C# using Microsoft's official guidance and patterns. Useful for Windows developers building new apps or troubleshooting WinUI-related setup and implementation challenges.
Create a real CLI that future Codex threads can run by command name from any working directory. This skill is for durable tools, not one-off scripts. If a short script in the current repo solves the task, write the script there instead. Name the target tool, its source, and the first real jobs it sh
Build professional-grade design systems in Figma that match code. This skill orchestrates multi-phase workflows across 20–100+ calls, enforcing quality patterns from real-world design systems (Material 3, Polaris, Figma UI3, Simple DS). Every design system build follows this phase order. Skipping o
This skill helps you generate custom design system rules tailored to your project's specific needs. These rules guide AI coding agents to produce consistent, high-quality code when implementing Figma designs, ensuring that your team's conventions, component patterns, and architectural decisions are
This skill enables users to generate and edit images directly within Claude Code using the OpenAI Image API, supporting use cases from product mockups to concept art. Developers and designers benefit by automating image creation workflows without leaving their coding environment.
Debugs and fixes failing GitHub Actions PR checks by inspecting logs and proposing solutions with explicit approval gates. Developers using GitHub Actions in CI/CD pipelines benefit from faster troubleshooting and fixes.
A meta-guide that helps users create or update specialized skills to extend Codex's capabilities with domain-specific knowledge and workflows. Developers and AI agents building custom extensions benefit from this structured approach to skill development.
Automates real browser interactions from the terminal using Playwright CLI for tasks like navigation, form filling, and data extraction. Useful for developers and AI assistants building UI automation workflows without writing test frameworks.
A skill for building and scaffolding ChatGPT Apps SDK applications that combine MCP servers with widget UIs, using a docs-first workflow. Developers building ChatGPT extensions and integrations benefit from structured guidance on tool design, UI registration, and SDK compliance.
