Convert PDF files to clean Markdown using Antigravity CLI (`agy`). Best for academic papers with math, tables, and structured content. The native pipeline feeds page-range chunk PDFs directly to Gemini's vision pathway (agy reads the PDF itself — no lossy text extraction), with an automatic quality-gated fallback to a Mathpix hybrid and Mathpix standalone. Zero marginal cost via a Google subscription. Triggers include "convert PDF to markdown with Antigravity", "agy PDF conversion", "PDF to markdown with math", and "convert paper to markdown".

Delegate heavy or token-expensive work from Claude Code to Codex CLI (GPT) and Antigravity CLI (Gemini), plus an independent Claude Code delegate (isolated config dir, OAuth subscription auth) usable as a 3rd voter or agentic worker. Use when a task is large, parallelizable, or benefits from cross-model verification: dispatch a self-contained prompt to an external CLI, write its output to a file, and read only the STATUS/VERDICT header to keep the main context clean. Good for code implementation, debugging, refactoring, proof and derivation checking, literature review, and any second-opinion cross-check. Triggers include "delegate to Codex/Antigravity", "cross-verify with ask_both", "run this in parallel", and "save tokens".
