name	meta-skill-gaps-dev
description	Identify skill coverage gaps and improvement opportunities. Use when analyzing missing skills for a task, creating skill gap issues, evaluating skill effectiveness, or refining skill progressive disclosure.

Skill Gap Analysis & Improvement

Systematic methodology for identifying missing skills and improving existing ones.

When to Use This Skill

• Analyzing skill coverage for a multi-domain task
• Creating issues for missing skills
• Evaluating whether loaded skills were effective
• Refining skills that loaded too much/too little context
• Identifying opportunities for derivative skills

Gap Detection

Domain Taxonomy

Map user requests to expected skill categories:

Domain Type	Pattern	Examples
Language	lang-<lang>-<pattern>-<focus>	lang-rust-library-dev, lang-zig-dev
Platform	cloud-<platform>-<service>-<focus>	cloud-aws-lambda-dev
Tool	<category>-<tool>-<focus>	iac-terraform-modules-eng
Service	<service>-<focus>	openmetadata-sdk-dev
Pattern	meta-<pattern>-<focus>	meta-library-dev, meta-sdk-patterns-eng
Method	method-<method>-<focus>	method-tdd-dev

Gap Detection Algorithm

1. Parse user request for domain keywords
2. For each keyword:
   a. Search local skills: content/skills/*<keyword>*
   b. Search loaded skills in current context
   c. If no match → GAP DETECTED
3. Check for compound gaps:
   - Language + Pattern (e.g., "Zig" + "library" → no lang-zig-library-dev)
   - Service + Pattern (e.g., "OpenMetadata" + "plugin" → no openmetadata-plugin-dev)

Gap Categories

Gap Type	Description	Priority
Complete	No skill for the domain at all	High
Derivative	Meta-skill exists but no domain-specific derivative	Medium
Compound	Domain skills exist separately but not combined	Medium
Depth	Skill exists but lacks needed detail	Low

Issue Creation Workflow

When to Create Issues

Create issue when:

• User confirms gap should be addressed
• Gap is "Complete" or "Derivative" type
• Domain is general enough to benefit future tasks

Skip issue when:

• One-off project-specific need
• User declines
• Very niche domain unlikely to recur

Issue Template

## Summary

Skill gap identified: No coverage for <domain>.

**Detected during:** <brief task description>
**Gap type:** <Complete | Derivative | Compound | Depth>
**User request snippet:** "<relevant quote>"

## Proposed Skill

| Field | Value |
|-------|-------|
| **Name** | `<proposed-skill-name>` |
| **Extends** | `<meta-skill if derivative>` |
| **Category** | `<lang \| cloud \| iac \| method \| ...>` |
| **Focus** | `<dev \| ops \| eng>` |

## Context

<Why this skill would be useful>

## Related Skills

- `<existing-related-skill-1>`
- `<existing-related-skill-2>`

GitHub CLI Command

gh issue create --repo aRustyDev/agents \
  --title "feat(skills): add <skill-name> skill" \
  --body "<issue-body>" \
  --label "skill-gap"

Skill Effectiveness Review

Review Triggers

Evaluate skills when:

• Task completes successfully
• User corrects Claude's approach
• User provides information the skill should have covered
• Significant context was loaded but unused

Evaluation Criteria

Criterion	Question	Score
Relevance	Did the skill match the task?	0-3
Coverage	Did it cover what was needed?	0-3
Precision	Was loaded context mostly used?	0-3
Accuracy	Was the information correct?	0-3

Scoring:

• 0 = Not at all
• 1 = Partially
• 2 = Mostly
• 3 = Completely

Action thresholds:

• Total < 6: Major revision needed
• Total 6-9: Refinement opportunities
• Total 10-12: Skill is effective

Common Issues

Symptom	Diagnosis	Solution
Large unused sections	Over-broad trigger	Narrow description keywords
User provided missing info	Coverage gap	Add missing section
Wrong approach suggested	Outdated content	Update with correct patterns
Too generic	Missing derivative	Create domain-specific skill
Loaded but not helpful	Trigger too broad	Refine trigger phrases

Progressive Disclosure Refinement

When to Refactor

Refactor skill structure when:

• SKILL.md exceeds 500 lines
• Specific sections rarely used together
• Different user personas need different depths

Refactoring Patterns

Extract to References:

Before: 800-line SKILL.md with everything inline

After:
├── SKILL.md (200 lines - overview, quick reference)
└── references/
    ├── detailed-workflow.md
    ├── api-reference.md
    └── troubleshooting.md

Split by Use Case:

Before: One skill covers dev + ops + troubleshooting

After:
├── <tool>-dev/SKILL.md     (development)
├── <tool>-ops/SKILL.md     (operations)
└── <tool>-debug/SKILL.md   (troubleshooting)

Create Derivatives:

Before: Generic skill tries to cover all languages

After:
├── meta-<pattern>-<focus>/SKILL.md     (foundational)
├── lang-rust-<pattern>-<focus>/SKILL.md  (Rust-specific)
└── lang-python-<pattern>-<focus>/SKILL.md (Python-specific)

Derivative Skill Detection

When to Suggest Derivatives

Suggest derivative when:

• Meta-skill loaded but user needs language-specific patterns
• Multiple languages/platforms apply same pattern
• User asks for " " combination

Derivative Gap Examples

User Request	Meta-Skill	Missing Derivative
"Zig library"	meta-library-dev	lang-zig-library-dev
"Python SDK for Stripe"	meta-sdk-patterns-eng	lang-python-sdk-dev
"Rust CLI tool"	meta-cli-patterns-dev	lang-rust-cli-dev
"Go plugin for OpenMetadata"	meta-plugin-dev	openmetadata-plugin-go-dev

Derivative Creation Checklist

Before creating derivative:

• Meta-skill exists and is stable
• Domain has enough specific content to warrant skill
• Not a one-off need
• User confirms value

Feedback Collection

What to Track

Data Point	Purpose
Skills loaded	Measure coverage
Sections referenced	Identify unused content
User corrections	Find accuracy issues
Missing information	Find coverage gaps
Task success/failure	Correlate with skill quality

Session Summary Format

## Skill Usage Summary

**Task:** <brief description>

### Skills Loaded

| Skill | Sections Used | Effectiveness |
|-------|---------------|---------------|
| `skill-1` | Overview, Quick Ref | High |
| `skill-2` | None (loaded but unused) | Low |

### Gaps Identified

- [ ] No skill for <domain-1>
- [ ] `skill-2` missing <topic> coverage

### Improvement Opportunities

- `skill-1`: Consider extracting <section> to reference
- `skill-2`: Trigger too broad, refine description
