🚨 EXECUTION NOTICE FOR CLAUDE

When you invoke this command via SlashCommand(/domain-plugin-builder:skills-create ...), the system returns THESE INSTRUCTIONS below.

YOU are the executor. This is NOT an autonomous subprocess.

• ✅ The phases below are YOUR execution checklist
• ✅ YOU must run each phase immediately using tools (Bash, Read, Write, Edit, TodoWrite)
• ✅ Complete ALL phases before considering this command done
• ❌ DON'T wait for "the command to complete" - YOU complete it by executing the phases
• ❌ DON'T treat this as status output - it IS your instruction set

Immediately after SlashCommand returns, start executing Phase 0, then Phase 1, etc.

See @CLAUDE.md section "SlashCommand Execution - YOU Are The Executor" for detailed explanation.

Security Requirements

CRITICAL: All generated files must follow security rules:

@~/.claude/plugins/marketplaces/dev-lifecycle-marketplace/docs/security/SECURITY-RULES.md

Key requirements:

• Never hardcode API keys or secrets
• Use placeholders: your_service_key_here
• Protect .env files with .gitignore
• Create .env.example with placeholders only
• Document key acquisition for users

Arguments: $ARGUMENTS

Goal: Create properly structured skill(s) by launching the skills-builder agent

CRITICAL EXECUTION INSTRUCTIONS:

• DO NOT wait for phases to run automatically
• DO NOT just explain what the phases do
• EXECUTE each phase immediately using the actual tools (Bash, Read, Write, Edit, TodoWrite, Task)
• The !{tool command} syntax shows you WHAT to execute - use the real tool to DO IT
• Complete all phases in order before finishing

Phase 0: Create Todo List

Create todo list for all phases below.

Phase 1: Discovery & Architecture Decision Framework Goal: Load comprehensive component decision framework to understand WHEN to use skills vs commands vs agents vs hooks vs MCP

Actions:

• Load the complete component decision framework: !{Read ~/.claude/plugins/marketplaces/domain-plugin-builder/plugins/domain-plugin-builder/docs/frameworks/claude/reference/component-decision-framework.md}
• This provides critical understanding of:
  • 🚨 START WITH COMMANDS FIRST (not skills!)
  • Commands are the primitive (closest to prompts)
  • Skills are for MANAGING multiple related commands
  • The "One-Off vs Management" test
  • When NOT to create a skill
  • Real composition hierarchy (skills use commands, not vice versa)
  • Complete decision tree with real examples
  • Anti-patterns to avoid
• This architectural decision-making context will be passed to the skills-builder agent
• Agent will understand when the requested functionality should be a COMMAND instead of a skill

Phase 2: Parse Arguments & Determine Mode

Actions:

Parse $ARGUMENTS to extract:

• Skill names and descriptions
• Plugin name (from --plugin=name or detect from pwd)
• Marketplace mode (check for --marketplace flag)

If plugin not specified:

!{bash basename $(pwd)}

Determine base path - check if already in a plugin directory:

!{bash test -f .claude-plugin/plugin.json && echo "." || (echo "$ARGUMENTS" | grep -q "--marketplace" && echo "plugins/$(basename $(pwd))" || echo ".")}

Store as $BASE_PATH:

• If .claude-plugin/plugin.json exists: BASE_PATH="." (already in plugin directory)
• Else if --marketplace present: BASE_PATH="plugins/$PLUGIN_NAME"
• Else: BASE_PATH="." (standalone plugin mode)

All subsequent file operations use $BASE_PATH instead of hardcoded "plugins/$PLUGIN_NAME"

Use bash to parse $ARGUMENTS and count how many skills are being requested:

!{bash echo "$ARGUMENTS" | grep -oE '<[^>]+>' | wc -l}

Store the count. Then extract each skill specification:

• If count = 0 and --analyze present: Set mode to "analyze", extract plugin name
• If count = 1: Single skill mode - extract <skill-name> and "<description>"
• If count >= 2: Multiple skills mode - extract all <skill-N> "<desc-N>" pairs

Phase 3: Launch Skills Builder Agent(s)

Actions:

For --analyze mode:

Task(description="Analyze plugin for needed skills", subagent_type="domain-plugin-builder:skills-builder", prompt="You are the skills-builder agent. Analyze the plugin structure at $BASE_PATH to determine what skills are needed.

Architectural context from component-decision-framework.md: @~/.claude/plugins/marketplaces/domain-plugin-builder/plugins/domain-plugin-builder/docs/frameworks/claude/component-decision-framework.md

Tasks:

1. Read detailed skills documentation via WebFetch:
   • https://docs.claude.com/en/docs/agents-and-tools/agent-skills/quickstart
   • https://docs.claude.com/en/docs/agents-and-tools/agent-skills/best-practices
   • https://docs.claude.com/en/docs/claude-code/skills
   • https://docs.claude.com/en/docs/claude-code/slash-commands#skills-vs-slash-commands
   • https://github.com/anthropics/claude-cookbooks/tree/main/skills
   • https://www.anthropic.com/engineering/equipping-agents-for-the-real-world-with-agent-skills
2. Analyze plugin commands and agents
3. Identify what reusable capabilities are needed
4. Report recommended skills to create

Plugin: $BASE_PATH Deliverable: List of recommended skills with descriptions")

Decision: 1-2 skills = build directly, 3+ skills = use Task() for parallel

For 1-2 Skills:

Build directly - execute these steps immediately:

1. Load decision framework: !{Read @component-decision-framework.md}

2. Load skill template: !{Read @SKILL.md.template}

3. For each skill: !{Bash mkdir -p $BASE_PATH/skills/$SKILL_NAME/{scripts,templates,examples}}

!{Write $BASE_PATH/skills/$SKILL_NAME/SKILL.md}

Create scripts, templates, and examples as needed.

4. Validate: !{Bash ~/.claude/plugins/marketplaces/domain-plugin-builder/plugins/domain-plugin-builder/skills/build-assistant/scripts/validate-skill.sh $BASE_PATH/skills/$SKILL_NAME}

No need for Task() overhead when building 1-2 skills

For 3+ Skills:

Launch multiple skills-builder agents IN PARALLEL (all at once) using multiple Task() calls in ONE response:

Task(description="Create skill 1", subagent_type="domain-plugin-builder:skills-builder", prompt="Create skill: $SKILL_1 - $DESC_1 [same prompt structure as single skill above]")

Task(description="Create skill 2", subagent_type="domain-plugin-builder:skills-builder", prompt="Create skill: $SKILL_2 - $DESC_2 [same prompt structure as single skill above]")

Task(description="Create skill 3", subagent_type="domain-plugin-builder:skills-builder", prompt="Create skill: $SKILL_3 - $DESC_3 [same prompt structure as single skill above]")

[Continue for all N skills requested]

Each Task() call happens in parallel. Parse $ARGUMENTS to determine how many Task() calls to make.

Wait for ALL agents to complete before proceeding to Phase 4.

Phase 4: Validation

Validate all created skills:

For each skill: !{bash ~/.claude/plugins/marketplaces/domain-plugin-builder/plugins/domain-plugin-builder/skills/build-assistant/scripts/validate-skill.sh $BASE_PATH/skills/$SKILL_NAME}

If validation fails, read errors and fix issues.

Phase 5: Sync to Airtable

Use bulk sync script for efficiency:

Bash: python ~/.claude/plugins/marketplaces/domain-plugin-builder/plugins/domain-plugin-builder/scripts/bulk-sync-airtable.py --plugin={plugin-name} --marketplace={marketplace-name} --type=skills

This syncs ALL skills in parallel instead of one at a time.

Environment Requirement:

• Requires AIRTABLE_TOKEN environment variable
• If not set, displays error message with instructions

Phase 6: Register Skills in Settings

CRITICAL: Skills must be registered to be usable!

Register all created skills in ~/.claude/settings.json:

!{bash ~/.claude/plugins/marketplaces/domain-plugin-builder/plugins/domain-plugin-builder/skills/build-assistant/scripts/register-skills-in-settings.sh $PLUGIN_NAME}

This registers entries like:

• Skill($PLUGIN_NAME:$SKILL_1)
• Skill($PLUGIN_NAME:$SKILL_2)
• etc.

Verify skills are accessible with Skill tool.

Phase 7: Git Commit and Push

Actions:

• Add all created skill directories to git: !{bash git add plugins//skills/}
• Commit with descriptive message: !{bash git commit -m "$(cat <<'EOF' feat: Add skill(s) - SKILL_NAMES

Complete skill structure with scripts, templates, and examples.

• Push to GitHub: !{bash git push origin master}

Phase 8: Self-Validation

Run validation script to verify all work completed:

!{bash ~/.claude/plugins/marketplaces/domain-plugin-builder/plugins/domain-plugin-builder/skills/build-assistant/scripts/validate-skill.sh $BASE_PATH/skills/*}

Mark all todos complete if validation passes.

Phase 9: Summary

Display results:

Skills Created: <count> Plugin: $PLUGIN_NAME Mode: $BASE_PATH (marketplace mode if "plugins/", standalone if ".") Location: $BASE_PATH/skills/

Files:

• $SKILL_1/ - $DESC_1 ✅
• $SKILL_2/ - $DESC_2 ✅
• etc.

Validation: All passed ✅ Registration: Complete ✅ Airtable Sync: Attempted ✅ Git: Committed and pushed ✅

Next Steps:

• Invoke skills: Skill($PLUGIN_NAME:$SKILL_NAME)
• Test skill functionality
• Update documentation
