use

A command that previews a skill's metadata and files without installing or changing anything. It can inspect local skills or skills from a source such as GitHub.

In plain words
What is it for?
Use it to inspect one skill, list skills in a collection, preview selected skills, or pipe their contents into other tools.
Why use it?
It lets you check instructions before adding them to an agent and avoids unwanted files being written to disk.

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

use 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 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.

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.

What it actually says

rolecraft use

Preview a skill's files without installing.

Usage

rolecraft use <source>
rolecraft use <source> --list
rolecraft use <source> --skill <name>

Description

Resolves the source, shows metadata, and prints all file contents to stdout — without writing anything to disk. Useful for inspecting a skill before installing, or piping content into other tools.

For sources with multiple skills (e.g. mattpocock/skills), all skills are shown sequentially. Use --skill to filter or --list to see only metadata.

Options

Flag Description
--list List available skills without previewing content
--skill <names> Preview specific skills by name (comma-separated)

Examples

# Preview a local skill
rolecraft use ./my-skill

# Preview a GitHub skill
rolecraft use rolecraft-sh/skills

# List skills in a multi-skill source
rolecraft use mattpocock/skills --list

# Preview a specific skill from a multi-skill source
rolecraft use mattpocock/skills --skill "typescript-rules"

# Pipe content
rolecraft use ./my-skill | head -50

Node.js API

This command is also available as a programmatic function. See the Node.js API documentation for detailed usage.

import { use } from 'rolecraft'
const preview = await use('./my-skill')
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.

use 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 336 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.
