MANDATORY skill creation framework for ALL skill creation requests. USE WHEN user wants to create, validate, update, or canonicalize a skill, OR user mentions skill creation, skill development, new skill, build skill, OR user references skill compliance, skill structure, or skill architecture.
/plugin marketplace add rafaelcalleja/claude-market-place/plugin install createskill-skill@claude-market-placeThis skill inherits all available tools. When active, it can use any tool Claude has access to.
references/BloggingExample.mdreferences/SkillSystem.mdworkflows/CanonicalizeSkill.mdworkflows/CreateSkill.mdworkflows/UpdateSkill.mdworkflows/ValidateSkill.mdMANDATORY skill creation framework for ALL skill creation requests.
Before creating ANY skill, READ: ${CLAUDE_PLUGIN_ROOT}/skills/Createskill/references/SkillSystem.md
Canonical example to follow: ${CLAUDE_PLUGIN_ROOT}/skills/Createskill/references/BloggingExample.md
All naming must use TitleCase (PascalCase).
| Component | Format | Example |
|---|---|---|
| Skill directory | TitleCase | Blogging, Daemon, CreateSkill |
| Workflow files | TitleCase.md | Create.md, UpdateDaemonInfo.md |
| Reference docs | TitleCase.md | ProsodyGuide.md, ApiReference.md |
| Tool files | TitleCase.ts | ManageServer.ts |
| Help files | TitleCase.help.md | ManageServer.help.md |
Wrong (NEVER use):
createskill, create-skill, CREATE_SKILLcreate.md, update-info.md, SYNC_REPO.mdWhen executing a workflow, output this notification directly:
Running the **WorkflowName** workflow from the **Createskill** skill...
| Workflow | Trigger | File |
|---|---|---|
| CreateSkill | "create a new skill" | workflows/CreateSkill.md |
| ValidateSkill | "validate skill", "check skill" | workflows/ValidateSkill.md |
| UpdateSkill | "update skill", "add workflow" | workflows/UpdateSkill.md |
| CanonicalizeSkill | "canonicalize", "fix skill structure" | workflows/CanonicalizeSkill.md |
Example 1: Create a new skill from scratch
User: "Create a skill for managing my recipes"
-> Invokes CreateSkill workflow
-> Reads SkillSystem.md for structure requirements
-> Creates skill directory with TitleCase naming
-> Creates SKILL.md, workflows/, tools/
-> Generates USE WHEN triggers based on intent
Example 2: Fix an existing skill that's not routing properly
User: "The research skill isn't triggering - validate it"
-> Invokes ValidateSkill workflow
-> Checks SKILL.md against canonical format
-> Verifies TitleCase naming throughout
-> Verifies USE WHEN triggers are intent-based
-> Reports compliance issues with fixes
Example 3: Canonicalize a skill with old naming
User: "Canonicalize the daemon skill"
-> Invokes CanonicalizeSkill workflow
-> Renames workflow files to TitleCase
-> Updates routing table to match
-> Ensures Examples section exists
-> Verifies all checklist items
This skill should be used when the user asks to "create an agent", "add an agent", "write a subagent", "agent frontmatter", "when to use description", "agent examples", "agent tools", "agent colors", "autonomous agent", or needs guidance on agent structure, system prompts, triggering conditions, or agent development best practices for Claude Code plugins.
This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for Claude Code.
This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.
