docs(command-development): improve discoverability and future-proof model ID examples

[sjnims]

Summary

Two minor documentation improvements for the command-development skill:

1. Missing "debug" trigger phrase - The skill description doesn't include "debug command" or "command debugging" despite testing-strategies.md covering debugging scenarios
2. Model ID examples may become stale - Specific model IDs like claude-sonnet-4-5-20250929 are used in examples

Issue 1: Missing Trigger Phrase

Current Description

description: This skill should be used when the user asks to "create a slash command", "add a command", ... or command development best practices for Claude Code.

Suggested Addition

Add trigger phrases:

• "debug command"
• "command debugging"
• "troubleshoot command"

This improves skill discoverability when users need help debugging their commands.

Issue 2: Model ID Examples

Location

plugins/plugin-dev/skills/command-development/references/frontmatter-reference.md

Current

model: sonnet   # or full model ID like claude-sonnet-4-5-20250929

Suggested

The existing note is good:

Note: Model ID examples above reflect December 2025 releases. Anthropic releases new model versions periodically. For current model IDs, consult Claude Models Overview.

Consider:

1. Using placeholder format: claude-<family>-<version>-<date>
2. Or simply noting "see official docs for current IDs"

This prevents examples from appearing outdated as new models release.

Acceptance Criteria

• Add "debug command", "command debugging", "troubleshoot command" to SKILL.md description
• Review model ID examples in frontmatter-reference.md for future-proofing
• Ensure link to official Claude models documentation is present and correct
