[Docs]: Update tools field examples in agent-development skill to use comma-separated format

[sjnims]

Which documentation needs improvement?

Skill documentation

Specific Location

plugins/plugin-dev/skills/agent-development/SKILL.md - Multiple locations showing tools field examples

What's unclear or missing?

The agent-development skill shows tools field using array format, but the official Claude Code documentation (sub-agents.md) uses comma-separated format. This inconsistency could cause users to use the wrong format when creating agents.

Current examples in SKILL.md (array format):

tools: ["Read", "Write", "Grep", "Bash"]

tools: ["Read", "Write", "Grep"]

Official format from sub-agents.md (comma-separated):

tools: Read, Grep, Glob, Bash

Note: The actual agents in this plugin (plugin-validator.md, skill-reviewer.md, agent-creator.md) correctly use the comma-separated format. Only the documentation examples are inconsistent.

Suggested Improvement

Update all tools field examples in the agent-development skill to use comma-separated format:

Before:

tools: ["Read", "Write", "Grep", "Bash"]

After:

tools: Read, Write, Grep, Bash

Locations to update:

1. Line 116-117 (Complete Format example):

   tools: Read, Write, Grep

2. Lines 230-232 (tools field format example):

   tools: Read, Write, Grep, Bash

3. Lines 239-241 (Common tool sets section) - update all examples to comma-separated format

4. Any other occurrences showing array format

Type of issue

• Incorrect information
• Outdated content

Additional Context

Found during comprehensive agent review comparing against:

• Official Claude Code sub-agents documentation: https://code.claude.com/docs/en/sub-agents.md
• Official plugins-reference documentation: https://code.claude.com/docs/en/plugins-reference.md

The official sub-agents.md documentation clearly shows:

tools: tool1, tool2, tool3  # Optional - inherits all tools if omitted

And the example agent uses:

tools: Read, Grep, Glob, Bash

This change ensures the skill documentation matches official Claude Code documentation and the actual format used by this plugin's agents.
