Design, review, and debug visual rendering tests: reftests (independent oracle), golden/snapshot regression tests, probe tests (pixel assertions without vision), SVG reftest suites, and Figma refig suites. Use when adding pixel diffs, choosing an oracle strategy, or comparing renderer output against a ground truth.

Research upstream and peer projects to inform Grida's design and implementation. Use when investigating how Chromium, Skia, Servo, Taffy, or peer canvas editors solve a problem before writing code. Covers source-code exploration and research document authoring under docs/wg/research/.

Doctrine for designing and evolving any SDK Grida ships — TypeScript, Rust, or otherwise. "SDK" here means a surface that crosses a foreign-or-foreign-treated boundary: published packages, separately-versioned consumers, FFI bindings, public-by-design modules. An SDK's job is to refuse; a strict, honest surface…

Discipline for the seam between two SDKs (or two sides of one contract) that the same hand writes. The failure mode: "we own both sides" produces dirty contracts no foreign reviewer would accept. The exercise: pretend the other side is FFI, IPC, or a network protocol you cannot rewrite. Spawn an adversarial subagent…

Query images with a local Ollama vision model without loading the image into the main agent context. Use when you need to describe a screenshot, check whether rendered content is present, detect overlapping elements, or ask any visual question about a PNG/JPEG/WebP file. Requires Ollama running locally with the Gemma…
