Skills Marketplace

The Skills Marketplace is groove's built-in store for agent skills. Browse, install, and purchase curated instruction sets that make your agents better at specific tasks — from frontend design to security auditing to code review.

What Are Skills?

A skill is a SKILL.md file — a set of instructions, best practices, and constraints that get injected into an agent's context when it starts. Think of them as expert playbooks that turn a general-purpose coding agent into a specialist.

For example, the Frontend Design skill teaches an agent to avoid generic AI aesthetics, use design tokens, and build production-grade interfaces. The Code Review skill teaches parallel review strategies with CLAUDE.md compliance checking.

Skills are provider-agnostic. They work with Claude Code, Codex, Gemini CLI, or any provider groove supports.

• Verification badge (Anthropic, Groove, or Verified)
• Description
• Star rating and download count
• Category tag
• Price (free or paid)

Search and Filter

• Search — find skills by name, description, or tags
• Categories — filter by Design, Quality, Dev Tools, Workflow, Security, or Specialized
• Sort — Popular, Top Rated, Newest, or A-Z

Getting Skills

Free Skills

Click a free skill to view its detail page, then click Download to get the .md file, or Apply to install it directly into your groove instance.

Downloaded skills are saved to your .groove/skills/ directory. No account required.

Paid Skills

Paid skills require an account. Click Buy $X.XX to be redirected to Stripe's secure checkout. After payment:

• You own the skill forever — no subscriptions, no recurring fees
• Download the .md file anytime from the skill page or your My Purchases page in the Studio
• Import it into any groove instance (local or VPS)

TIP

80% of every purchase goes directly to the skill creator. The platform takes 20% to cover infrastructure and payment processing.

Attaching Skills to Agents

Installing a skill makes it available. Attaching it to an agent activates it.

At Spawn Time

When spawning a new agent, you'll see a Skills section in the spawn panel listing your installed skills. Toggle the ones you want — they'll be injected into the agent's context when it starts.

On Running Agents

Select a running agent, go to the Actions tab, and scroll to the Skills section. Click + Attach Skill to add a skill, or click the x next to an attached skill to detach it.

TIP

Attaching a skill to a running agent updates its record, but the skill instructions only take effect on the next rotation or restart. For immediate effect, rotate the agent after attaching.

How Injection Works

When an agent spawns with attached skills, groove's introducer loads each SKILL.md, strips the frontmatter, and injects the instruction body into the agent's context under a ## Skills section. The agent receives the full instructions automatically — no manual copy-pasting.

Rating Skills

Help the community find the best skills by rating them. On the skill detail page, click the stars to submit your rating (1-5 stars). Your rating is factored into the aggregate score shown on the card.

Verification Badges

Trust indicators help you identify quality skills:

Badge	Meaning
Anthropic (gold)	Official skills from Anthropic
Groove (teal)	Skills built and maintained by the groove team
Verified (green)	Community creators who have completed verification

Unverified community skills show no badge — they may still be great, but haven't been reviewed yet.

Default Skills

groove ships with 21 official skills from Anthropic, covering:

• Design — Frontend Design, Playground Builder
• Quality — Code Review, Code Simplifier, PR Review Toolkit
• Dev Tools — Build MCP Server, Build MCP App, Skill Creator, Hook Development, Agent Development, and more
• Workflow — Feature Development, Commit Commands, Explanatory Output, Learning Output

• Specialized — Math Olympiad

These are free, open-source (Apache 2.0), and serve as examples of well-structured skills.

Offline Support

The daemon caches the skill registry locally. If you lose internet connectivity:

• Installed skills continue to work (they're local files)
• The marketplace falls back to the bundled registry
• New installs may fail until connectivity is restored

No data is lost offline. The daemon syncs with the live registry on the next startup.
