Foundry's cast CLI for Ethereum interactions. Use when querying blockchain data, calling contracts, sending transactions, encoding/decoding data, or debugging on-chain issues. Triggers on "cast", "get balance", "call contract", "decode calldata", "check tx", "get block".

Arbitrum L2 development best practices. Use when implementing bridges, Orbit chains, SDK integrations, or debugging cross-chain transactions. Triggers on Arbitrum, L2, rollup, bridge, retryable, Orbit, Nitro, or cross-chain contexts.

Create or improve lightweight, brand-consistent SVG concept diagrams for the Arbitrum docs, using the official Google Drive infographic asset kit as the palette/style source. Use when asked to "make a diagram more efficient", replace a bloated haw-*.svg (draw.io PNG-in-SVG exports), replace an ASCII / box-drawing diagram in an MDX page with a real image, author a new concept diagram for content/docs/how-arbitrum-works or similar, or build a diagram from the Arbitrum brand assets. Hand-authored lean vector SVG — not Mermaid, not a full Excalidraw/draw.io pipeline.

Use when asked to rebrand, restyle, re-pace, resize, or re-render an existing explainer video, when a video's labels are baked-in raster pixels that cannot be edited, or when building a new animated explainer for the Arbitrum docs from a prompt or a doc section.

Run full documentation quality audit, covering sidebar orphans, unused-file review, MDX structure, internal links, glossary references, contract addresses, variables, formatting, frontmatter, tests, and types. Triggers on "audit docs", "check docs quality", "find problems", "content audit".
