grida: Skill for Claude Code

.agents/skills/code-ts/SKILL.md

code-ts is a skill for Claude Code, Codex from gridaco/grida. It costs 99 tokens per session (1,185 once invoked), scanned A, original, Apache-2.0.

TypeScript code-organization guidance for keeping each well-named module focused on one main class or namespace. It emphasizes arranging code so the file's structure matches what tests and callers use.

In plain words
What is it for?
It helps decide how to group classes, namespaces, types, and helper functions in TypeScript files, especially in the specified editor and canvas code areas.
Why use it?
It reduces scattered exports and keeps related behavior together, making modules easier to test, search, replace, and maintain. It complements ordinary TypeScript naming conventions.

About the project

Grida is an open-source graphics workspace that combines an infinite canvas editor, SVG tools, a database and CMS, and forms. Designers and developers use it to create, import, render, and manage visual documents and connected data, while the catalogue add-ons support its workflows.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-ts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.

code-ts

Vanilla TS conventions (PascalCase types, kebab-case files, use-* hooks) are table stakes — assume them. This is the taste on top. Where naming decides the boundary of a module, code-ts decides what the code inside that boundary looks like so it stays testable and the boundary keeps doing its job.

One class or one namespace per file

The exported unit should be a single thing a test can target: one class with cohesive methods, or one export namespace (or const-as-namespace) wrapping related functions. Avoid the alternative — a file that exports ten free functions and a handful of types side-by-side.

Why:

  • import { css } from "./css" then asserting against css.toReactCSSProperties(...) mirrors the file's structure 1:1. Tests, callers, and grep all read the same shape.
  • Scattering free exports loses the gate naming worked to establish. The file becomes a bag — anything can drift in alongside.
  • The unit becomes mockable and replaceable as a contract, not a pile of helpers.

The repo lives this. editor/grida-canvas/data-transfer.ts is a 24-line export namespace datatransfer carrying a type, a key, and an encode/decode pair, and nothing else. editor/grida-canvas-utils/css.ts is a single export namespace css with ~20 CSS-conversion functions inside, paired one-to-one with editor/grida-canvas-utils/css.test.ts. editor/grida-canvas/editor.ts is the Editor class — the engine's front door, one contract surface for everything downstream.

Not class or namespace everywhere

This is not "always use a class" or "always use a namespace." It is that the code most worth grouping in this repo — engine logic, library modules, contract-bearing utilities — is overwhelmingly stateful or spec-bearing, and reads better that way. UI glue, route handlers, one-shot scripts, and small page-local helpers can be plain exports.

Heuristic: if the filename is a noun that naming would approve (one concept, strict, honest), the contents probably want to live under that noun as a class or namespace. If the file is named for its location in a feature flow (page.tsx, loader.ts, route.ts), free exports are fine.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
