agent: update custom commands to follow Claude Code slash commands guide

[p-iknow]

Requirement

Resolves #8

Update all existing custom Claude Code commands to follow the official slash commands guide at https://docs.claude.com/en/docs/claude-code/slash-commands

The guide mandates frontmatter metadata for better discoverability, context provision, and proper tool integration. Commands without frontmatter lack the metadata that SlashCommand tool uses for context and user guidance.

Implementation

Updated make-branch.md

• Added YAML frontmatter:
  • description: Brief explanation for SlashCommand tool context
  • argument-hint: Shows expected input format [<type>]: <description>\n#<issue-index>
  • allowed-tools: Specifies Bash(git checkout:*) permission for branch creation
• Preserved all existing content structure

Updated make-pr.md

• Added YAML frontmatter:
  • description: Explains command purpose for SlashCommand tool context
  • allowed-tools: Specifies Bash(gh:*) and Bash(git:*) permissions for PR workflow
• No argument-hint needed as command doesn't accept arguments
• Preserved all existing content structure

No changes to make-commit.md and make-task-issue.md

• Both already have proper frontmatter following the guide
• Already compliant with best practices

Test

• Verified frontmatter syntax is valid YAML
• Confirmed all required fields per guide are present (description, allowed-tools)
• Validated argument-hint format matches guide examples
• Ensured existing command functionality is preserved

Reference

• Official guide: https://docs.claude.com/en/docs/claude-code/slash-commands
• Guide requirements:
  • "Always include description" - SlashCommand tool uses this in context
  • "Specify allowed tools" - Required for Bash operations
  • "Provide argument hints" - Guide users on expected inputs
