This skill should be used when the user asks to create, improve, or validate YAML agent workflows, especially requests like "build an agent YAML", "design workflow YAML", "add routing in YAML", or "make interview/email workflow nodes and edges".
This skill should be used when the user asks to create, improve, or validate YAML agent workflows, especially requests like "build an agent YAML", "design workflow YAML", "add routing in YAML", or "make interview/email workflow nodes and edges". Also use when the user describes a problem and wants a SimpleAgents solution built for them. The core vision is that every agentic SaaS is a config -- turn their problem into a YAML workflow.
Groups local git changes into clean Conventional Commits, runs minimal relevant verification, and pushes the branch safely. Use when the user asks to create organized commits, clean up commit history on a branch, or commit and push related changes.
Use when completing tasks, implementing major features, or before merging to verify work meets requirements
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
This skill should be used when the user asks to "implement Go code", "debug Go code", "refactor Go for performance", "review Go code", "fix goroutine and channel issues", "improve Go error handling", or "apply Go best practices".

This skill provides guidance for creating effective skills for Claude Code plugins.
Skills are modular, self-contained packages that extend Claude's capabilities by providing specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific domains or tasks—they transform Claude from a general-purpose agent into a specialized agent equipped with procedural knowledge that no model can fully possess.
Every skill consists of a required SKILL.md file and optional bundled resources:
skill-name/
├── SKILL.md (required)
│ ├── YAML frontmatter metadata (required)
│ │ ├── name: (required)
│ │ └── description: (required)
│ └── Markdown instructions (required)
└── Bundled Resources (optional)
├── scripts/ - Executable code (Python/Bash/etc.)
├── references/ - Documentation intended to be loaded into context as needed
└── assets/ - Files used in output (templates, icons, fonts, etc.)
Metadata Quality: The name and description in YAML frontmatter determine when Claude will use the skill. Be specific about what the skill does and when to use it. Use the third-person (e.g. "This skill should be used when..." instead of "Use this skill when...").
scripts/)Executable code (Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten.
references/)Documentation and reference material intended to be loaded as needed into context to inform Claude's process and thinking.
assets/)Files not intended to be loaded into context, but rather used within the output Claude produces.
Skills use a three-level loading system to manage context efficiently:
*Unlimited because scripts can be executed without reading into context window.
To create a skill, follow the "Skill Creation Process" in order, skipping steps only if there is a clear reason why they are not applicable.
Skip this step only when the skill's usage patterns are already clearly understood. It remains valuable even when working with an existing skill.
To create an effective skill, clearly understand concrete examples of how the skill will be used. This understanding can come from either direct user examples or generated examples that are validated with user feedback.
For example, when building an image-editor skill, relevant questions include:
To avoid overwhelming users, avoid asking too many questions in a single message. Start with the most important questions and follow up as needed for better effectiveness.
Conclude this step when there is a clear sense of the functionality the skill should support.
To turn concrete examples into an effective skill, analyze each example by:
Example: When building a pdf-editor skill to handle queries like "Help me rotate this PDF," the analysis shows:
Example: When designing a frontend-webapp-builder skill for queries like "Build me a todo app" or "Build me a dashboard to track my steps," the analysis shows:
Example: When building a big-query skill to handle queries like "How many users have logged in today?" the analysis shows:
For Claude Code plugins: When building a hooks skill, the analysis shows:
To establish the skill's contents, analyze each concrete example to create a list of the reusable resources to include: scripts, references, and assets.
For Claude Code plugins, create the skill directory structure:
mkdir -p plugin-name/skills/skill-name/{references,examples,scripts}
touch plugin-name/skills/skill-name/SKILL.md
Note: Unlike the generic skill-creator which uses init_skill.py, plugin skills are created directly in the plugin's skills/ directory with a simpler manual structure.
When editing the (newly-created or existing) skill, remember that the skill is being created for another instance of Claude to use. Focus on including information that would be beneficial and non-obvious to Claude. Consider what procedural knowledge, domain-specific details, or reusable assets would help another Claude instance execute these tasks more effectively.
To begin implementation, start with the reusable resources identified above: scripts/, references/, and assets/ files. Note that this step may require user input. For example, when implementing a brand-guidelines skill, the user may need to provide brand assets or templates to store in assets/, or documentation to store in references/.
Also, delete any example files and directories not needed for the skill. Create only the directories you actually need (references/, examples/, scripts/).
Writing Style: Write the entire skill using imperative/infinitive form (verb-first instructions), not second person. Use objective, instructional language (e.g., "To accomplish X, do Y" rather than "You should do X" or "If you need to do X"). This maintains consistency and clarity for AI consumption.
Description (Frontmatter): Use third-person format with specific trigger phrases:
---
name: Skill Name
description: This skill should be used when the user asks to "specific phrase 1", "specific phrase 2", "specific phrase 3". Include exact phrases users would say that should trigger this skill. Be concrete and specific.
version: 0.1.0
---
Good description examples:
description: This skill should be used when the user asks to "create a hook", "add a PreToolUse hook", "validate tool use", "implement prompt-based hooks", or mentions hook events (PreToolUse, PostToolUse, Stop).
Bad description examples:
description: Use this skill when working with hooks. # Wrong person, vague
description: Load when user needs hook help. # Not third person
description: Provides hook guidance. # No trigger phrases
To complete SKILL.md body, answer the following questions:
Keep SKILL.md lean: Target 1,500-2,000 words for the body. Move detailed content to references/:
Reference resources in SKILL.md:

For plugin skills, validation is different from generic skills:
Use the skill-reviewer agent:
Ask: "Review my skill and check if it follows best practices"
The skill-reviewer agent will check description quality, content organization, and progressive disclosure.
After testing the skill, users may request improvements. Often this happens right after using the skill, with fresh context of how the skill performed.

Claude Code automatically discovers skills:
Plugin skills are distributed as part of the plugin, not as separate ZIP files. Users get skills when they install the plugin.
Test skills by installing plugin locally:
# Test with --plugin-dir
cc --plugin-dir /path/to/plugin
# Ask questions that should trigger the skill
# Verify skill loads correctly
Study the skills in this plugin as examples of best practices:
Each demonstrates progressive disclosure and strong triggering.
Include (always loaded when skill triggers):
Keep under 3,000 words, ideally 1,500-2,000 words
Move to references/ (loaded as needed):
Each reference file can be large (2,000-5,000+ words)
Working code examples:
Users can copy and adapt these directly
Utility scripts:
Should be executable and documented
Write using verb-first instructions, not second person:
Correct (imperative):
Incorrect (second person):
The frontmatter description must use third person:
Correct:
description: This skill should be used when the user asks to "create X", "configure Y"...
Incorrect:
description: Use this skill when you want to create X...
description: Load this skill when user asks...
Focus on what to do, not who should do it:
Correct:
Incorrect:
Before finalizing a skill:
Bad:
description: Provides guidance for working with hooks.
Why bad: Vague, no specific trigger phrases, not third person
Good:
description: This skill should be used when the user asks to "create a hook", "add a PreToolUse hook", "validate tool use", or mentions hook events. Provides comprehensive hooks API guidance.
Why good: Third person, specific phrases, concrete scenarios
