agency-agents
msitarzewski
Open-source collection of specialized AI agent personalities installable into Claude Code, Cursor, Codex and more.
Key features
- Specialized Agent Roster: Role-specific agents with deep domain expertise rather than generic prompt templates.
- Personality-Driven Design: Each agent has its own voice, communication style and approach.
- Deliverable Focus: Agents define real code, processes and measurable outcomes.
- Desktop Installer App: A native app for macOS, Linux and Windows installs agents with a click and auto-updates.
- Multi-Tool Support: Works with Claude Code, Cursor, Codex, Gemini CLI, OpenCode, Qwen, Windsurf and others.
- Selective Installation: Install only the divisions or teams you need.
Best for
- A developer installs a frontend specialist agent into Claude Code for UI work.
- A founder assembles a virtual agency of marketing and product agents.
- A team uses agent files as reference for writing its own agent prompts.
- A user installs the same roster across Cursor and Codex with the desktop app.
- A community manager adapts a community-focused agent for social outreach.
- A contributor submits a new specialized agent through a pull request.
Google Stitch
Google LLC
Generates UI designs for mobile and web from prompts, sketches, or images to speed design ideation and prototyping.
Key features
- Prompt-to-UI Generation: Produces UI screens for mobile and web from natural-language prompts, sketches, or images to accelerate ideation and mockup creation.
- Sketch and Image Import: Accepts user sketches or images as input and converts them into UI layouts and visual designs to jumpstart the design process.
- Gemini CLI Extension: Provides a Gemini CLI extension enabling natural-language interaction with a Stitch MCP server for generating UIs and managing requests from the terminal.
- MCP Server & Proxy Tooling: Offers an MCP (Managed Control Plane) workflow and proxy utilities to host a Stitch MCP server, route requests, and facilitate local development/testing.
- GCP Integration & Authentication: Integrates with Google Cloud tooling (gcloud) for authentication, Application Default Credentials, project selection, and IAM role setup required to enable the Stitch API.
- CLI-based Setup & Diagnostics: Includes command-line installers and setup commands (e.g., npx @_davideast/stitch-mcp init) that automate installation, enable APIs, configure credentials, and diagnose setup issues.
- Generates UI designs for mobile and web from prompts, sketches, or images
- Hosted Stitch web application for interactive design ideation
- Stitch MCP API for programmatic access and server integration
- Gemini CLI extension to interact with Stitch via natural language commands
- MCP proxy server capability for local/dev proxying of Stitch MCP
- CLI-driven setup and provisioning (npx init, gemini extensions install)
- Google Cloud authentication support (gcloud auth, Application Default Credentials)
- IAM-based access control requirements and project-level service enablement
Best for
- Rapid Design Ideation: Quickly generate multiple UI concepts from a brief or sketch to explore interface directions during early-stage product design.
- Sketch-to-Prototypes: Convert hand-drawn sketches or screenshots into digital UI screens that designers can refine and iterate on.
- Developer Handoff Automation: Produce consistent UI outputs that designers can export or hand off to developers along with configuration for Stitch MCP to streamline implementation.
- CLI-driven Design Workflows: Integrate UI generation into terminal-driven workflows using the Gemini CLI extension for teams that prefer code/CLI environments.
- Enterprise Self-hosting & Control: Deploy and run a Stitch MCP server with GCP integration and IAM controls to maintain access governance and combine Stitch with internal toolchains.
- Local Development & Testing: Use the MCP proxy and diagnostic commands to test Stitch-generated UIs and API interactions in local or staging environments before production rollout.
- Rapid design ideation and exploration of mobile/web UI concepts
- Convert sketches or screenshots into polished UI screens for prototyping
- Automated UI generation in developer workflows via CLI or API
- Integrating AI-driven UI generation into a Google Cloud-based toolchain
- Local development and testing using an MCP proxy server
- CI/CD automation to generate or refresh design assets programmatically
