A curated list of open-source AI skills and repositories for content creators, marketers and teams looking to automate routine tasks.

Client discovery and business fit

Specialized skills analyze public signals, rank prospects by product fit and timing, and surface the most promising outreach targets for early customers.

• codex-first-customer-finder-skill — accepts a startup URL, assesses public pain signals and demand, and ranks potential first customers by fit and timing; this repository was retweeted by Greg Brockman (president and co-founder of OpenAI).

Agent infrastructure

Frameworks and validators help assemble multi-agent systems, enforce quality checks, and operate agents in parallel from resource-constrained devices.

• Superpowers — a productivity base for brainstorming, planning and composing subordinate agent skills for iterative workflows.

• Orca — tooling for parallel agents, enabling CLI-driven agents such as Claude Code or Codex to run and be controlled from mobile devices.
• telegram-mcp — a package with 80+ Telegram utilities for reading chats, scheduling messages, managing groups and handling media through a single MCP server.

Video and voice

Open-source audio and video skills support transcription, TTS, voice cloning and agent-level video understanding for content repurposing workflows.

• CosyVoice — open-source TTS from Alibaba supporting 9 languages, including Russian, able to clone a voice from a short sample with latency from 150 ms.
• claude-video — enables an agent to "watch" videos by downloading clips, extracting frames and producing transcriptions for downstream processing.
• notebooklm-py — an unofficial Python API for NotebookLM that functions as both a CLI and a skill integration for agent platforms.

These open-source projects can be combined into pipelines for content production, audience discovery and automation across marketing, product and community workflows.
