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…

How to handle GRIDA-SEC- security boundaries in the Grida repo. Triggers when you encounter a GRIDA-SEC tag in source/docs, when modifying files under any tagged path, or when adding a new prevented- vulnerability record. Each GRIDA-SEC- identifies a structural trust boundary documented in /SECURITY.md. This skill…

SEO best practices for the Grida project across Next.js pages, blog posts, and documentation. Covers Next.js metadata API, Open Graph / Twitter cards, sitemaps, image search optimization, structured data (JSON-LD), Docusaurus frontmatter, and content writing for search. Use when creating or editing public-facing pages…

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…

Author and edit a Grida .canvas board — a .canvas.json manifest plus document files (references, generated images, notes) placed on an infinite canvas. Use when working on a .canvas bundle or arranging visuals/design work spatially. For a linear deck/presentation, use the slides skill instead.
Skill Claude CodeCodex
Build a Grida slides deck — a .canvas bundle in slides mode whose pages are SVG documents (16:9, one SVG per slide). Use when creating a presentation, pitch deck, slideshow, or talk.
Skill Claude CodeCodex
Author and edit .svg files in a Grida editor session — live-canvas binding, SVG output style, and parse-error recovery. Use when creating or modifying an SVG document.

Manual-invocation only. Five-phase feature loop (audit → ground → fixture → implement → verify) for driving a single SVG feature to Chromium parity in the grida htmlcss::svg renderer. Sibling to dev-render-htmlcss-feature (HTML/CSS path); same loop shape, different corpus (resvg-test-suite + Chrome bake) and different…

Doctrine for drafting and keeping working-group docs under docs/wg/ — RFC/RFD specs and findings/research/glossary. A WG doc is a language-agnostic, code-agnostic study of a domain: it argues why and defines what, never how in our code. Use when writing or editing anything under docs/wg/, an RFC/RFD, a spec, a design…

Bug-fix discipline — every defect has an etiology, the chain of cause that produced the observable fault; trace it before patching. Errors only grow: a bandaid leaks unless genuinely localized and leak-free. Walk the diagnostic ladder (presentation → proximate cause → API contract → isolated or systemic) before…

Guides authoring, organizing, and referencing test fixtures across the engine repo. Use when creating new fixtures, writing tests that depend on fixtures, or deciding what should be checked into git.
Skill Claude CodeCodex
Guides work on the Grida file format (.grida): the FlatBuffers schema and the Rust decoder that loads it into the canvas runtime. Use when working with .grida files, the FlatBuffers schema, codegen, or debugging format issues. (The TS reader/writer packages live in the grida product repo.).

Guides work on SVG import into the Grida Canvas Rust engine (grida crate). Covers crates/grida/src/import/svg/, the gridadev svg-to-grida CLI, cross-boundary FBS codec tests (Rust encode → TS decode), SVG fixture authoring, and known SVG import limitations (text model, filters, transforms). Use when adding SVG feature…

Write any link or URL so it resolves where it is rendered, not where it lives in the repo. Use when authoring or editing a link — in docs/wg specs, crate READMEs and docstrings, the npm-published wasm package README, or skills. This is the engine-repo variant of the grida links doctrine.

How to think about names in the Grida repo — not conventions, but what a name commits you to, reveals about the system, and costs to change. The central discipline is that a strict, honest name refuses to grow, and that refusal drives the repo's shape (flat modules, small agnostic packages, suffix siblings). Use when…

Pre-PR discipline for a public-by-default repo. What a reviewer enforces beyond CI: secrets and internal data in diffs or screenshots, docs that name their reader, and the cleaning pass where incomplete or confusing artifacts get dropped. Use before opening any PR against gridaco/nothing or when finalizing work for…

Role profile — a reviewer who is fact-seeking, bedrock-seeking, honest, and rejecting. Demands that arguments rest on small facts that cannot be wrong (not on stacked assumptions dressed up as foundation), and that deliberately-unclear concepts be quarantined — never leaked into solid layers, never mixed with each…

Guides performance optimization work on the Grida Canvas Rust rendering engine (grida crate). Use when asked to benchmark, profile, optimize, or analyze rendering performance — panning, zooming, compositing, caching, culling, or frame budgeting.
