Build Claude Code Plugin Skills
Creating plugin skills can be inconsistent without a clear structure. This skill gives practical guidance for planning, writing, organizing, and validating skills.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "skill-development" from https://skillstore.io/skills/skill-development.md and its manifest at https://skillstore.io/api/skills/skill-development/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.
Agent-readable resources
Use these links when an AI agent, crawler, or script needs clean context instead of reading the full page.
Test it
Using "skill-development". Create a skill for internal API support.
Expected outcome:
- A focused skill purpose and trigger list.
- A plan for reference material, examples, and optional scripts.
- A validation checklist for description quality and structure.
Using "skill-development". Review this existing plugin skill.
Expected outcome:
Findings cover vague triggers, oversized main instructions, missing resource links, and writing style issues. Suggested edits are grouped by priority.
Using "skill-development". Plan resources for a complex workflow skill.
Expected outcome:
- Core workflow guidance stays in the main skill file.
- Detailed patterns move into references.
- Reusable examples and helper scripts are listed separately.

Create a Plugin Skill
Plan the purpose, triggers, folder structure, and reusable resources for a new Claude Code plugin skill.
Improve an Existing Skill
Refine trigger descriptions, split large instructions into references, and align writing style with skill guidance.
Review Skill Organization
Check whether instructions, references, examples, and scripts are placed in the right parts of a plugin skill.
Try These Prompts
Create a Claude Code plugin skill for [domain]. Ask for missing trigger phrases before drafting the skill content.
Review these user examples and recommend which guidance belongs in the main skill, references, examples, or scripts.
Audit this SKILL.md for specific triggers, third-person frontmatter, imperative wording, and clear resource references.
Design a complete plugin skill for [workflow], including reusable resources, validation steps, and progressive disclosure boundaries.
Best Practices
- Start from concrete user examples before writing skill instructions.
- Keep the main skill file focused and move detailed material into references.
- Validate trigger phrases, writing style, resource links, and examples before publishing.
Avoid
- Do not use vague descriptions that fail to match real user requests.
- Do not place every detailed reference in the main skill file.
- Do not leave scripts, examples, or references unmentioned in the main instructions.
