thesvg: Instructions file for Codex

AGENTS.md

thesvg AGENTS.md is an instructions file for Codex, OpenCode from glincker/thesvg. It costs 1,552 tokens per session, scanned A, original, MIT.

Submission rules for SVG icons, the XML-based format used for scalable vector graphics. They define required files, sizing, colors, accessibility text, and restrictions on unsafe or embedded content.

In plain words
What is it for?
Adding brand icons, validating SVG structure, checking color variants, and updating the icon registry.
Why use it?
They give an agent clear checks for whether an icon matches the project’s standards. This reduces rejected submissions and invisible or unsafe SVGs.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is glincker/thesvg's own configuration. It tells Codex and OpenCode how to work on thesvg 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 thesvg configures →

About the project

theSVG is an open-source collection of thousands of SVG brand logos and cloud-service icons that developers can search and use in software projects. It is intended for developers working with React, Vue, Svelte, HTML, CDNs, or package-based workflows, and the catalogue add-ons help coding agents work with the icon collection.

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

thesvg 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 10d 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.

thesvg - AI Review Guidelines

SVG Icon Submission Rules

Required

  • Every icon directory must have default.svg
  • Every SVG must have a valid viewBox attribute
  • Every SVG must contain a <title> element with the brand name
  • Preferred viewBox: 0 0 24 24 (match library convention)
  • File size must be under 50KB
  • No <script> tags, event handlers, or javascript: URIs
  • No embedded raster images (<image> with base64 data)
  • No <?xml> declarations or <!DOCTYPE> preambles

Fill and Color Rules

  • default.svg: Must use the brand hex color as fill on <svg> root (not currentColor)
  • mono.svg: Must use fill="currentColor" on <svg> root
  • light.svg: Must use fill="#ffffff" or similar light color
  • dark.svg: Must use fill="#1a1a2e" or similar dark color
  • Detail elements (eyes, pupils, accents) that contrast with the body must have explicit fill overrides - they must not inherit the root fill if that makes them invisible
  • Stroke colors on antennae, lines, or accents must contrast with adjacent filled shapes - same-color strokes over same-color fills are invisible
  • Never include a viewport-covering rectangle like <path d="M0 0h24v24H0z"/> without fill="none" - this covers the entire icon

icons.json Registry

  • Located at src/data/icons.json
  • Entries must be alphabetically sorted by slug
  • Required fields: slug, title, aliases, hex, categories, variants, license, url
  • hex must not include # prefix (e.g. "f43f5e" not "#f43f5e")
  • variants object keys must match filenames in public/icons/{slug}/
  • categories must use existing category names (check existing entries)

Variant File Naming

public/icons/{slug}/
  default.svg          # Required - brand color
  mono.svg             # Recommended - inherits text color
  light.svg            # Optional - for dark backgrounds
  dark.svg             # Optional - for light backgrounds
  color.svg            # Optional - multi-color/gradient version
  wordmark.svg         # Optional - text logo
  wordmarkLight.svg    # Optional - light text logo
  wordmarkDark.svg     # Optional - dark text logo

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.
