OpenClaw Skills with High Adoption: Capability Evolver, WACLI, Composio, and More

A post on r/openclaw lists several OpenClaw skills that have gained traction based on install numbers and user feedback. The skills serve distinct purposes, from agent self-improvement to external tool integration.

Key Skills and Their Functions

• Capability Evolver: 35k installs, #1 on ClawHub. It enables an agent to audit itself and gradually rewrite its own behavior over time.
• Self-Improving Agent: 15k installs, 132 stars. It picks up patterns from user interaction and improves its responses specifically for that user. Can be run alongside Capability Evolver as they focus on different aspects.
• WACLI: 16k installs. Provides full WhatsApp access from an agent, allowing it to send messages, pull conversation history, and search threads.
• Composio: A single skill that connects an agent to 860+ apps (e.g., Gmail, Slack, GitHub, Notion, Jira, Linear) through Composio's auth layer, handling OAuth properly so tokens are not stored near the agent.
• GoG: 14k installs. One skill for all of Google Workspace: Gmail, Calendar, Drive, Docs, Sheets, and Contacts, avoiding the need for several separate integrations for the same account.
• Agent-Browser: Gives an agent a real browser to click, fill forms, navigate pages, and extract data from sites that block basic scraping.
• Tavily-Web-Search: A search tool designed for agents, returning results in a format agents can use directly without extra parsing.
• DuckDB: Enables SQL queries over local files (CSV, Parquet, JSON, etc.) without setting up a database.
• AgentZero Bridge: When a task is too long or complex for OpenClaw to handle in one pass, it hands the task off to Agent Zero and brings the result back, with bidirectional communication to keep the user in the loop.
• ArXiv-Watcher: Monitors arXiv for specified topics or authors and surfaces new papers automatically.
• n8n Workflow Skill: Triggers and manages n8n workflows from inside OpenClaw, with credentials staying in n8n.
• Memory-Hygiene: Clears out stale context, contradictions, and outdated preferences from OpenClaw memory to prevent old context from affecting new sessions.
• GitHub: Wraps the GitHub CLI as a skill to manage issues, pull requests, branches, and repo workflows through chat.
• Debug-Pro: Implements a structured debugging methodology into the agent, walking through systematic isolation and resolution steps across languages.
• Test-Runner: Writes and runs tests from a single instruction, handling scaffolding, execution, and result interpretation in one pass across multiple languages.

The post suggests these skills are worth trying based on their adoption metrics and practical applications.
