blocklet-converter is a skill for Claude Code, Codex from ArcBlock/agent-skills. It costs 43 tokens per session (1,108 once invoked), scanned A, original, MIT.

A converter that turns a static website or Next.js project into an ArcBlock Blocklet using a supplied project identifier called a DID. A static website mainly serves prepared files, while Next.js is a JavaScript web framework.

In plain words
What is it for?
Use it to convert an HTML-based site or Next.js application into a Blocklet, provided you have a valid Blocklet DID.
Why use it?
It automates project inspection and configuration while rejecting unsupported back-end applications or missing web projects. It also validates the generated setup.

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

blocklet-converter 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (parse-project-meta.js), 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.

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.

Blocklet Converter

Converts static web projects and Next.js applications into ArcBlock blocklets with proper configuration and validation.

Parameters

did (required): Pre-generated blocklet DID (format: z8ia...)

Example: "Convert this project to blocklet using DID z8ia4e5vAeDsQEE2P26bQqz9oWR1Lxg9qUMaV"

If missing or invalid, exit immediately with error message: "Blocklet DID parameter is required."

Workflow

1. Project Analysis

Skip directories: node_modules/, .pnpm/, .yarn/, .cache/, .turbo/, bower_components/

Verify Web Application Exists

Check for ANY of:

  • package.json with web-related dependencies
  • index.html in root, public/, or src/ or common locations
  • Web framework config (vite.config.*, webpack.config.*, next.config.*, etc.)

If none found → EXIT with error message: "No web application detected."

Detect Project Type

Check package.json dependencies for:

  • Next.js: next in dependencies → Next.js project
  • Backend frameworks: express, koa, fastify, nest, etc. → EXIT with error: "Only static webapp and next.js projects are supported."
  • OtherwiseStatic webapp
Extract & Emit Metadata (Early)

Immediately after confirming project type, extract metadata from package.json:

  • title: Human-friendly project name suitable for public display (e.g., my-cool-appMy Cool App)
  • description: A clear, non-technical description for end users. If package.json description is too technical, rewrite it to be user-friendly.

Emit using the protocol below, then continue with the workflow:

<<<BLOCKLET_PROJECT>>>
{"title": "...", "description": "..."}
<<<END_BLOCKLET_PROJECT>>>
Build (if build script exists)
bun install && bun run build

If either fails → EXIT with error output.

Locate Output Directory

For Next.js projects: Output directory is always .next — skip detection.

For static webapps: Find index.html in: dist/build/out/public/./, or any other common locations. If not found → EXIT with error message: "No index.html entry point found."

Files

What ships with it

8 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.
