- [Context.dev](https://staging.leyline.ahensya.com/components/context-dev.md): Context.dev (also @getcontextdev; YC S26 per founder/company bios) markets itself as a unified web-context API for software and agents: scrape, crawl, search, brand/people enrichment, monitors, MCP, and SDKs — one API key.
- [Sitegeist](https://staging.leyline.ahensya.com/components/sitegeist.md): Sitegeist is an AI assistant that lives in a Chromium side panel, plus a bridge so coding agents can use the same browser. README framing: collaboration over “autonomy theater” — you guide, it executes. Automates repetitive web tasks, extraction, navigation, forms, research → docs/spreadsheets; BYO API key or subscription login (Anthropic, OpenAI/ChatGPT, GitHub Copilot, Gemini, etc.); claims local-only / no tracking.
- [Fix Cold Start Latency in AI Sandboxes: Techniques](https://staging.leyline.ahensya.com/components/fix-cold-start-latency-in-ai-sandboxes-techniques.md): # How to fix cold start latency in AI sandboxes: techniques and tradeoffs
- [Needle 3](https://staging.leyline.ahensya.com/components/needle-3.md): Needle 3 is Cactus Compute’s on-device “automation foundation model”: a laddered / sliceable tiny model (post: 8–29 MB CQ2-bit binary; 25–121M params; depths 2–20 layers from one weight set) built on their Simple Attention Networks, aimed at tool calls, structured extraction, and local text embeddings — not open-ended chat.
