init

A command that creates a starter SKILL.md file for a new agent skill. SKILL.md is the instruction file that defines what a skill does and how an agent should use it.

In plain words
What is it for?
Use it to begin a new skill, choose a template, and prepare the files for later installation.
Why use it?
It avoids starting from an empty file and supplies the expected metadata and structure.

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.

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

init 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 3d 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.

rolecraft init

Scaffold a new SKILL.md for your agent skill.

Usage

rolecraft init                               # create ./my-skill/SKILL.md (default: my-skill)
rolecraft init my-custom-tool                # create ./my-custom-tool/SKILL.md
rolecraft init namespace/skill               # create ./namespace-skill/SKILL.md
rolecraft init --list                        # list available templates
rolecraft init my-skill --template basic     # scaffold from a template
rolecraft init my-skill --template react     # scaffold with React best practices

Description

Generates a ready-to-edit SKILL.md with proper slug, name, and owner metadata. Edit it with your skill instructions, then install with rolecraft install <dir>.

Use --list to see all available templates. Use --template <name> to scaffold from a specific template that pre-fills sections, MCP server configuration, or agent targeting for common patterns.

Options

Option Description
--list List all available templates with descriptions
--template <name> Scaffold from a named template instead of the default

Available templates

Template Description
basic General-purpose skill template for AI agent instructions
code-review Code review guidelines and best practices for AI agents
git-workflow Git workflow conventions and branch strategy for AI agents
testing Testing guidelines and best practices for AI agents
security Security guidelines and dangerous pattern detection for AI agents
react React best practices and component patterns for AI agents

When no --template flag is provided, a minimal frontmatter scaffold is created (backward-compatible with older versions).

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.

init is a command published in the GitHub repository rolecraft-sh/rolecraft (75 stars, last pushed 5d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 706 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
