In plain words
What is it for?
Use it to choose or create a starter project with a name and optional description. It reports the files created and the commands needed for the next steps.

Command for Claude Code

Part of the create-starter plugin — 2 skills, 8 commands, 1 MCP server shipped together

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Or install create-starter, the plugin that ships this one along with the rest of its 2 skills, 8 commands, 1 MCP server.

Per session 40 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 283 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 1 finding. Scan, not verified.
Origin original No closer match found in the catalogue.
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

scaffold 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 2d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- Shell out to `curl`, `tar`, or `git clone` — the MCP server handles fetch, extract, placeholder substitution, and `git init` atomically.

What it actually says

You are scaffolding a new project from the Starter Series templates via the create-starter MCP server.

Steps

  1. If the user did not name a template, call list_templates and ask them to pick one.
  2. Collect required inputs:
    • name (required) — must match ^[A-Za-z0-9][A-Za-z0-9_-]*$ (alnum start, then [A-Za-z0-9_-]). No dots, spaces, or path separators.
    • description (optional) — one-line description that replaces the template default.
  3. Call create_project with the validated inputs.
  4. Report what was created, including the matched starter, files written, and any next-step commands from the post-scaffold report.

Do NOT

  • Shell out to curl, tar, or git clone — the MCP server handles fetch, extract, placeholder substitution, and git init atomically.
  • Run the new project's install/build/dev commands automatically — surface them to the user instead.
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.

scaffold is a command published in the GitHub repository starter-series/create-starter (1 stars, last pushed 15d ago), licensed MIT. It adds 40 tokens to every session and 283 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
