19.3 Top 10 Skills by Install Count — In Depth

Listed in order of downloads, with a deep dive into each Skill:

#1 Capability Evolver (35k downloads)

Categories: Coding Agents / AI & LLM

Core function: Enable OpenClaw to improve itself — based on the user's work patterns, it automatically suggests and applies new Skill configurations.

How it works:

1. Analyzes recent conversation history
2. Identifies recurring task patterns
3. Automatically generates new Skills to handle those patterns
4. Suggests the user install these custom Skills

Installation:

clawhub install capability-evolver

Use case:

User: "What tasks do I do most often? Is there anything that can be automated?"
→ Capability Evolver analyzes conversation history and makes suggestions

Note: This is a meta-skill — it creates other Skills. Requires OpenClaw to have write access to the Skills directory.

#2 Wacli (16k downloads)

Categories: Browser Automation

Core function: Web Automation CLI — converts web interactions into repeatable CLI command sequences.

Key features:

• Record mode: captures browser operations and generates replayable scripts
• Batch mode: applies the same operations to multiple URLs
• Data extraction: structured extraction of tables, lists, and other page data

Installation:

clawhub install wacli

Usage examples:

/wacli record            → start recording mode
/wacli play my-script.yaml  → replay recorded operations
/wacli extract --url https://site.com --selector ".price"  → extract data

#3 ByteRover (16k downloads)

• Zero downloads + newly published (unverified)

19.5 Installation Methods: clawhub install vs. Manual

clawhub install (Recommended)

# Install to global Skills directory (~/.openclaw/skills/)
clawhub install <slug>

# Install into the current project
clawhub install <slug> --local

# Install a specific version
clawhub install <slug>@1.2.3

clawhub install gog github summarize

Advantages:

• Automatic dependency handling (tools in the install field)
• Version locking (generates an openclaw.lock file)
• One-command updates

Manual Installation

# 1. Create the Skills directory (if it doesn't exist)
mkdir -p ~/.openclaw/skills/my-skill

# 2. Create SKILL.md
cat > ~/.openclaw/skills/my-skill/SKILL.md << 'EOF'
---
name: my-skill
description: My custom Skill
---

19.6 Skills Update Strategy

Check Available Updates

clawhub update --check
# Output:
# gog: 1.2.0 → 1.3.0 (breaking: requires.env changed)
# github: 2.1.0 → 2.1.1 (patch: fixed PR template)
# summarize: 1.0.0 → 1.0.0 (up to date)

Update a Single Skill

clawhub update gog

Update All (Use with Caution)

clawhub update --all

Recommendation: Don't blindly update everything. Breaking changes can break automated workflows that depend on a Skill. Always read the changelog before updating.

Pin Versions (Recommended for Production)

# openclaw.lock example
{
  "skills": {
    "gog": "1.2.0",
    "github": "2.1.0",
    "summarize": "1.0.0"
  }
}

In team projects, commit openclaw.lock to Git to ensure all team members use the same versions.

19.7 Using ClawHub's Vector Search Effectively

ClawHub's search engine uses vector embeddings, meaning it understands search intent rather than just matching keywords.

Search Techniques

Technique 1: Search with scenario descriptions, not tool names

# Poor search
clawhub search "ffmpeg"

# Better search
clawhub search "compress and convert video files"

Technique 2: Use question-form queries

clawhub search "how to create github pull request automatically"
clawhub search "analyze code performance bottlenecks"

Technique 3: Filter by category

clawhub search "web scraping" --category "Browser Automation"
clawhub search "code review" --category "Coding Agents"

Technique 4: Filter by OS

clawhub search "image resize" --os darwin

Technique 5: Filter by minimum downloads (exclude unverified Skills)

clawhub search "pdf processing" --min-downloads 500
