feat(agent-development): add comparative trigger phrases to skill description

[sjnims]

Summary

• Add 4 new trigger phrases to the agent-development skill description
• Improves discoverability for comparative and conceptual questions

Problem

Fixes #17

Users asking questions like "what's the difference between an agent and a skill?" wouldn't discover the agent-development skill, despite it having an excellent comparison table.

Solution

Added these specific trigger phrases to the description:

• "difference between agent and skill"
• "agent vs command"
• "when should I use an agent"
• "agent schema"

Alternatives Considered

• Adding a separate FAQ skill - rejected as agent-development already has comprehensive comparison content
• Modifying skill body - unnecessary since triggering is the issue, not content

Changes

• plugins/plugin-dev/skills/agent-development/SKILL.md: Added 4 trigger phrases to description

Testing

• Description under 1024 character limit (580 chars)
• Markdownlint passes
• Skill triggers on test queries (e.g., "what's the difference between an agent and a skill?")

What's Good

✅ Clean, targeted change: The PR adds exactly 4 trigger phrases as described, with no scope creep or unnecessary modifications.

✅ Excellent trigger phrase selection: The new phrases are spot-on for the content:

• "difference between agent and skill" - directly maps to the comparison table in lines 19-25
• "agent vs command" - same comparison content
• "when should I use an agent" - covered in "When to Use Agents vs Commands vs Skills" (lines 27-46)
• "agent schema" - maps to frontmatter fields section (lines 88-188)

✅ Markdown quality: markdownlint passes with no issues.

✅ Description length: Actual length is 593 characters (including the newline from echo), well under the 1024 character limit. PR description claimed 580 chars, which is close enough (the slight difference is likely from how the character count was measured).

✅ Good commit message: Follows conventional commits format, explains the "why", includes proper attribution.

✅ Addresses a real problem: Issue #17 correctly identified that users asking comparative questions wouldn't discover this skill. The skill has excellent comparison content (the table at lines 19-25), so improving discoverability makes perfect sense.

What's Good

✅ Perfectly targeted skill trigger phrases (commit 5185a0e):

• Added 4 new trigger phrases that map directly to existing skill content:
  • "difference between agent and skill" → comparison table at SKILL.md:21-25
  • "agent vs command" → same comparison table
  • "when should I use an agent" → "When to Use Agents vs Commands vs Skills" section at SKILL.md:27-46
  • "agent schema" → frontmatter fields documentation at SKILL.md:88-189
• Description length: 593 characters (well under 1024 limit)
• Solves real discoverability problem from issue feat(agent-development): strengthen trigger phrases in skill description #17

✅ Smart workflow fix (commit 47bcbf8):

• Removed obsolete version field validation from skill checks
• Aligns with changes in commit 8521d81 that removed version from skill frontmatter
• Correctly removes both the version check and the now-unnecessary plugin.json read step
• Workflow logic is sound: skills no longer have versions, so don't validate them

✅ Quality standards met:

• Markdownlint passes with no errors
• YAML frontmatter structure correct
• Trigger phrases follow third-person pattern ("This skill should be used when...")
• No scope creep or unnecessary changes
• Conventional commit messages with clear rationale

---

Markdown Linting

✅ All markdown files pass markdownlint --config .markdownlint.json

---

Workflow Validation Analysis

The workflow change correctly addresses the version field removal:

Before: Validated 3 required fields: name, description, version
After: Validates 2 required fields: name, description

This matches the current skill structure (confirmed by reading the skill file - no version field present).

Trigger Phrase Analysis

All 4 new trigger phrases align perfectly with existing content:

Trigger Phrase	Content Location	Assessment
"difference between agent and skill"	Comparison table (lines 19-25)	✓ Excellent match
"agent vs command"	Same comparison table	✓ Excellent match
"when should I use an agent"	"Choose Agents When" (lines 27-32)	✓ Excellent match
"agent schema"	Frontmatter fields (lines 88-189)	✓ Excellent match

The skill already contains comprehensive comparison content - these phrases will help users discover it when asking conceptual questions.
