grida: Skill for Claude Code

.agents/skills/desktop/SKILL.md

desktop is a skill for Claude Code, Codex from gridaco/grida. It costs 133 tokens per session (2,988 once invoked), scanned A, original, Apache-2.0.

Development guidance for the Electron desktop shell around a web application. It covers native windows, preload code, menus, links opened by the operating system, file associations, packaging, and the bridge between Electron and the app.

In plain words
What is it for?
It helps modify Electron windows, menus, preload and bridge code, deep links, file handling, single-instance and multi-window behavior, packaging, branding, and desktop UI verification.
Why use it?
It keeps desktop-only changes separate from the web application and highlights the security and release impact of changing native entry points or the renderer bridge.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is gridaco/grida's own configuration. It tells Claude Code and Codex how to work on grida itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything grida configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is Adjacent: [`security`](../security/SKILL.md) for the GRIDA-SEC-004 trust.

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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

desktop scanned grade A with 1 finding 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/audit-release-impact.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Grida Desktop - Electron Shell

This skill is for the Electron shell only: main process, windows, menus, preload, native protocol/file entry points, and the renderer bridge surface. The renderer is still the editor's Next.js app under editor/app/desktop/; Electron URL-loads it from http://localhost:3000/desktop/* in dev and https://grida.co/desktop/* in prod.

Use agent-system for the daemon + agent-tenant core, sessions, workspaces, providers, tool execution, HTTP routes, and tests in packages/grida-daemon and packages/grida-ai-agent.

Adjacent: security for the GRIDA-SEC-004 trust boundary, code-react for React code under editor/app/desktop/** and editor/scaffolds/desktop/**.

When to use this skill

  • Editing desktop/src/**, desktop/forge.config.ts, desktop/Info.plist, or desktop packaging/dev-server wiring.
  • Changing desktop/src/main.ts, window.ts, menu.ts, preload, bridge contract, app branding, host-app integration, deep links, file associations, single-instance behavior, or multi-window routing.
  • Touching editor/app/desktop/**, editor/scaffolds/desktop/**, or editor/lib/desktop/** because the UI depends on window.grida.
  • Debugging "works in browser but not in desktop" or "only repros in Electron" issues.
  • Verifying the desktop app through CDP / Playwright.
  • Touching CSP or proxy behavior for /desktop/*.
  • Auditing whether linked-package or hosted Desktop renderer changes require a native version bump or coordinated release.

Use agent-system to implement core agent behavior that can be tested without Electron: packages/grida-daemon/**, packages/grida-ai-agent/**, daemon HTTP routes, sessions, files/workspaces, providers, tools, runtime, skills, and BYOK/secrets. Also use this skill when auditing whether that work changes the packaged Desktop payload or its compatibility with the hosted renderer.

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.
