사용하기 좋은 상황

• Use this skill when the task matches the package name, repository context, or skills.sh topic: design.
• Prefer it when a repeatable workflow is better than a one-off prompt: setup, review, design, deployment, automation, research, media generation, or operational checks.
• For production work, read the linked repository and install command before allowing the agent to run scripts or modify files.

Agent 사용 방식

1. Confirm the user intent and whether this skill is the right fit.
2. Install or inspect the skill with the official command from skills.sh.
3. Read the local SKILL.md and only load extra files referenced by that skill.
4. Follow the skill's workflow, then verify the result with tests, screenshots, audits, or source-backed checks as appropriate.
5. Record any constraints, missing credentials, tool permissions, or security warnings before handoff.

• Never grant broad shell, browser, cloud, or deployment permissions without user approval.
• Treat generated output as draft until validated by the skill's own acceptance criteria.
• If the skill touches cloud resources, costs, credentials, customer data, or production deploys, require a human review step.

FAQ

Is mcp-builder an agent, a prompt, or a skill?
It is a skill: a reusable package of task-specific instructions and supporting files that an agent can load when the user's request matches the workflow.

Should I install it automatically?
Only after checking the repository, install command, audit status, and whether the user wants this capability in the current agent environment.

What makes it useful for AIDreamHub users?
It helps users discover practical agent capabilities from the open skills ecosystem and compare them by task, source, install count, and operational risk.
