Skill Advisor

Search, compare, and install skills correctly to preferred agents.

Determine Operation Type

What does the user want?

• Find and install new skills → Follow Installation Workflow
• Remove existing skills → Read references/recovery.md
• Fix broken installation → Read references/recovery.md
• Update skills → Run npx skills check then npx skills update

Installation Workflow

Copy this checklist and track progress:

Skill Installation:
- [ ] Step 1: Search with multiple keywords
- [ ] Step 2: Preview and read SKILL.md
- [ ] Step 3: Compare and categorize (High/Medium/Low)
- [ ] Step 4: Generate install commands (no --all!)
- [ ] Step 5: Verify installation

Step 1: Search Skills

Search with multiple related keywords for better coverage:

npx skills find QUERY
npx skills find RELATED_QUERY

Step 2: Preview and Read SKILL.md

Preview each repository's available skills:

npx skills add owner/repo -g --list

Read actual SKILL.md content at:

https://skills.sh/owner/repo/skill-name

Never rely solely on skill names. Names can be misleading.

Step 3: Compare and Recommend

Evaluate each skill:

Quality criteria:

• High: Scripts, detailed references, concrete examples, actionable workflows
• Medium: Useful guidance but mostly text-based
• Low: Generic content, replaceable by general LLM knowledge

Output format:

## Recommended (Category/Author)
| Skill | Function | Quality | Note |
|-------|----------|---------|------|
| skill-a | Actual function from SKILL.md | High | Why recommended |

## Optional
| Skill | Function | Quality | Note |
|-------|----------|---------|------|
| skill-b | Function from SKILL.md | Medium | Supplements skill-a |

## Not Recommended
| Skill | Function | Quality | Note |
|-------|----------|---------|------|
| skill-c | Function from SKILL.md | Low | Overlaps with skill-a |

Step 4: Generate Install Commands

CRITICAL: Never use --all flag — it overrides --agent and installs to ALL 41 agents.

Rules:

1. Only generate install commands for High quality skills
2. Medium quality: list in Optional section, commands provided separately
3. Low quality: no install commands

Correct pattern:

npx skills add owner/repo -g -s skill1 -s skill2 -a antigravity -a claude-code -a gemini-cli -a opencode -y

Parameters:

Wrong vs Right:

# WRONG — --all overrides -a, installs to ALL agents
npx skills add expo/skills -g -a claude-code --all

# RIGHT — explicit -s and -a flags
npx skills add expo/skills -g -s xlsx -s pdf -a antigravity -a claude-code -a gemini-cli -a opencode -y

Step 5: Verify Installation

# List installed skills
npx skills ls -g

# Check symlinks exist
ls -la ~/.claude/skills/
ls -la ~/.gemini/skills/
ls -la ~/.gemini/antigravity/skills/
ls -la ~/.config/opencode/skills/

# Verify no unwanted directories
ls ~/.cursor/ ~/.augment/ 2>/dev/null

Default Target Agents

For all 41 supported agents, read references/agents.md.

Common Pitfalls

1. --all flag: Overrides --agent, installs to 41 agents, creates unwanted directories
2. Forgetting -g: Installs to project only
3. Missing -s: May install all skills or prompt interactively
4. Trusting skill names: Always read SKILL.md content

Example

User request: "Find a skill for processing Excel files"

Response:

## Search

|-------|----------|---------|------|
| xlsx | Create spreadsheets, analyze data, generate charts | High | Official skill, full-featured |

## Install Command
npx skills add expo/skills -g -s xlsx -a antigravity -a claude-code -a gemini-cli -a opencode -y

## Verify
npx skills ls -g
