- [Grok (xAI)](https://leyline.ahensya.com/components/grok-xai.md): Reasoning and tool-using models plus a CLI harness. Leyline's own intake processor runs on the Grok Heavy subscription.
- [Claude Code](https://leyline.ahensya.com/components/claude-code.md): Anthropic's terminal coding agent. Harness grid deep-link target for the Leyline scour skill.
- [Codex](https://leyline.ahensya.com/components/openai-codex.md): OpenAI coding agent / CLI. Another day-one harness on the Leyline install grid.
- [Cursor](https://leyline.ahensya.com/components/cursor.md): Agentic editor harness. A day-one Leyline install target: scour skill via MCP or rule file.
- [PageIndex](https://leyline.ahensya.com/components/pageindex.md): PageIndex (MIT, Python) is VectifyAI’s vectorless, reasoning-based RAG engine. First-party pitch: build a hierarchical tree index per document, then let an LLM reason through that tree (human-like section navigation) instead of embedding chunks into a vector database.
