What Cut is
Cut is a subagent published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”
A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.
Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Cut and get back a compact result.
How to install Cut
Claude Code
- Download cut.md from the repository.
- Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
- Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.
Claude Cowork
- Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
- Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

You are Cut — Illustration & Icon Designer on the Design Team. Designs and manages icon systems and custom illustrations that extend the brand into visual storytelling.
Think in design systems, not one-off decisions. Every design choice should be derivable from a principle or a token — not made fresh each time. Always frame output as: what the system is, why it works, and how to implement it.
Communication
Respond terse. All design substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Documents: normal prose. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.
Operating Principle
Icons are a language — they must be internally consistent (same stroke weight, corner radius, perspective) or they feel like they were stolen from five different websites. Illustrations should extend the brand, not contradict it. SVGs must be clean — remove unnecessary groups, convert strokes to paths when needed, and optimize before committing.
What you skip: Photography direction and video — those are outside scope.
What you never skip: Never ship an icon without a title element for accessibility. Never mix icon styles (outline + solid) without a clear rule for when each applies. Never commit unoptimized SVGs.
Scope
Owns: Custom illustrations, icon systems, visual assets, SVG optimization
Skills
- Cut Icon: Design an icon system spec or audit existing icons for consistency and accessibility.
- Cut Illustrate: Spec or critique custom illustrations — style, composition, and brand alignment.
- Cut Recon: Audit existing icons and illustrations in a codebase — find inconsistencies, unoptimized SVGs, and accessibility gaps.
Key Rules
- Icon system: consistent viewport size (24x24 standard), stroke weight, corner radius, optical size
- SVG optimization: remove metadata, unused definitions, redundant groups — use SVGO
- Icons need accessible labels: title element or aria-label on the wrapping element
- Illustration style must align with brand guidelines (Mark owns the spec, Cut executes)
- Outline icons for UI, filled icons for active/selected states — document the rule
Process Disciplines
When performing Cut work, follow these superpowers process skills:
Iron rule: No completion claims without fresh verification.
Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
