A command-line tool that turns SVG icons into typed components for React, Preact, Solid, Qwik, Vue, or Svelte projects. SVG is a file format for scalable vector graphics.

Use it to initialize an icon setup, add or remove Iconify icons, list and export them, or generate icon files for a supported framework.

It avoids manually copying and adapting individual icons and keeps icons available in the framework format your project uses.

denji — Skill for Claude Code and Codex by fellipeutaka/leon

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/fellipeutaka/leon

agentmods

npx agentmods add skills/fellipeutaka/leon/denji

Made for: Claude Code, Codex.

Or install frontend, the plugin that ships this one along with the rest of its 35 skills.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00106	$0.02902
Opus 5.5	$0.00042	$0.01161
Sonnet 5.5	$0.00021	$0.00580
Haiku 4.5	$0.00011	$0.00290

Security

Grade A, and why

denji 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.

Managing SVG Icons with Denji

Denji converts Iconify SVG icons into typed framework components. Icons are fetched, optimized (SVGO), and generated as native components for your framework.

Core Workflow

# 1. Initialize project
npx denji init --framework react --output ./src/icons.tsx

# 2. Add icons (prefix:name format from Iconify)
npx denji add lucide:check lucide:x lucide:arrow-right

# 3. Use in your code

import { Icons } from "./icons";

<Icons.Check className="size-4 text-green-500" />
<Icons.X className="size-4 text-red-500" />

Commands

`denji init`

Initialize a Denji project. Creates denji.json config and icons template.

npx denji init
npx denji init --framework react --output ./src/icons.tsx
npx denji init --framework svelte --output ./src/icons --output-type folder
npx denji init --framework react --no-typescript --output ./src/icons.jsx
npx denji init --a11y hidden --forward-ref

Flag	Description
`--framework <name>`	`react`, `preact`, `solid`, `qwik`, `vue`, `svelte`
`--output <path>`	Output path for icons file/folder
`--output-type <type>`	`file` (single file) or `folder` (one file per icon)
`--typescript` / `--no-typescript`	TypeScript or JavaScript (default: TS)
`--a11y <strategy>`	`hidden`, `img`, `title`, `presentation`, or `false` (no a11y attrs)
`--forward-ref` / `--no-forward-ref`	Use forwardRef (React/Preact only)
`--track-source` / `--no-track-source`	Track Iconify source via `data-icon` attr
`-c, --cwd <path>`	Working directory

Missing flags trigger interactive prompts.

`denji add <icons...>`

Add icons from Iconify. Icons use prefix:name format.

npx denji add lucide:check
npx denji add lucide:check mdi:home radix-icons:cross-2
npx denji add lucide:star --name FavoriteStar
npx denji add lucide:info --a11y img
# Preview without writing files
npx denji add lucide:check mdi:home --dry-run

Flag	Description
`--name <name>`	Custom component name (single icon only)
`--a11y <strategy>`	Override a11y strategy for this icon
`--dry-run`	Preview what would be generated without writing any files
`-c, --cwd <path>`	Working directory

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
