Wireloom: Instructions file for Codex

AGENTS.md

Wireloom AGENTS.md is an instructions file for Codex, OpenCode from StardockCorp/Wireloom. It costs 11,434 tokens per session, scanned A, original, MIT.

A small text language for sketching user-interface wireframes as inline SVG images. A wireframe is a rough layout showing where screens, forms, and controls go before the finished design is built.

In plain words
What is it for?
Use it to sketch screens, dialogs, settings pages, sign-in forms, and other interface layouts for discussion or planning.
Why use it?
It lets an AI agent describe a screen in readable indented text and render the result in tools that support SVG. The output is a monochrome mockup rather than a finished interface.

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

Wireloom AGENTS.md 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.

Wireloom for AI Agents

You are reading this because you need to render a UI wireframe mockup. Wireloom is a small text DSL for sketching user-interface layouts as inline SVG. This file is written for LLM agents (Claude, Codex, Cursor, etc.) that need to author wireframes — copy or link it into your agent's context when working on UI design tasks.

What is Wireloom?

Wireloom is a small indentation-based text language for UI wireframe mockups. You write a layout as indented plain text inside a ```wireloom fenced code block, and the Wireloom renderer turns it into an SVG wireframe. Output is monochrome, sketch-style — it reads as a mockup, not a finished UI.

Because Wireloom outputs plain SVG, the same block renders in GitHub, Obsidian, Notion, static site generators, or any Markdown tool that handles SVG. The read side needs no per-host plugin — only the authoring side needs the renderer (via npm install wireloom or a tool that bundles it).

When to Use Wireloom

Use Wireloom when the user asks for:

  • "Mock up a screen / dialog / settings page / sign-in form…"
  • "Draw a wireframe for…"
  • "Sketch the layout of the new UI"
  • "Show me how this feature would look"
  • "Diagram the toolbar / inspector / split view"
  • Any request about the shape of a user interface that isn't already a running app

When NOT to Use Wireloom

If the user wants… Use instead
Flowchart, sequence, class, ER, or state diagram mermaid fenced block
Interactive prototype you can click through A real component in their frontend framework (React, Svelte, Vue…)
Architecture / concept / dependency map with freeform nodes A whiteboard/canvas tool or Mermaid graph
A real, working form or tool Actual code in the target framework

Wireloom is strictly for static structural mockups. If the ask is "can you make this tool / dashboard / page actually work?", write the real component instead.

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.
