10 Claude Code features worth actually learning
CLAUDE.md is the first thing to set up. It loads every session automatically. Stack, naming conventions, rules you'd otherwise re-explain constantly. Write it once.
Context degrades past 90% capacity. Claude Code gets measurably worse, not just slower. Between tasks, run /clear. That's it.
Escape Escape opens a checkpoint menu that lets you rewind both code and conversation to any earlier state. If a session goes sideways, you're not stuck with it.
Worktrees keep main clean. claude -w feature-branch spins up an isolated git worktree. Claude Code commits and opens pull requests there. Your main branch stays untouched.
The -p flag makes Claude Code composable. Pipe logs, diffs, files directly in: git diff main | claude -p "review". Non-interactive, scriptable, works in any pipeline.
Effort level is not maxed by default. There are four: low, medium, high, max. On hard problems, pass --effort high explicitly.
Auto memory is on by default. Claude Code saves build commands, project quirks, and your preferences across sessions without you doing anything.
Set a spend cap for automated runs. --max-budget-usd 5.00 combined with --max-turns 3 prevents runaway costs in continuous integration and continuous delivery setups.
Path-scoped rules keep things tidy. Rules in .claude/rules/api.md only load when you're in API files. Test rules stay in test files. No bleedover between contexts.
Named sessions make parallel work manageable. claude -n "auth-refactor" names the session. claude -r "auth-refactor" picks it back up later. Multiple workstreams, no context collisions.

The 25+ OpenClaw Skills Worth Installing
1. StartClaw (run in production)
where is your agent actually running?
Most people start locally. That works until you close your laptop and your agent goes offline, or a skill with shell access does something unexpected on the same machine as your SSH keys and personal files. The blast radius of a misconfigured skill on a local setup is your entire environment.
StartClaw puts OpenClaw on a dedicated cloud instance, isolated from your personal machine. Pick your model, connect Telegram, WhatsApp, or Discord from a single dashboard, and your agent is live in under 60 seconds. No Docker, no server provisioning, no configuration files.
The rest of this list assumes your agent is always on.
2. Web Browsing (bundled)
Gives your agent live internet access: page navigation, content extraction, link following. Without it, you're working with a chatbot on stale training data.
Most installed skill on ClawHub at 180,000+ installs. Comes pre-bundled, nothing to add.
3. Telegram
Connects your agent to Telegram via a BotFather token. You message it from your phone, it responds. Setup is around five minutes, latency is surprisingly low.
145,000+ installs. Good for anyone who needs to reach their agent away from a desktop.
Install: clawhub.ai/codedao12/telegram
4. Google Workspace (GOG)
Gmail, Calendar, Drive, Contacts, Sheets, and Docs through one integration. Your agent can clear your inbox, schedule meetings, and organize documents without you touching any of it.
Install: clawhub.ai/steipete/gog
5. Capability Evolver
A self-evolution engine where the agent automatically improves its own capabilities over time through machine learning feedback loops.
Most downloaded skill on ClawHub overall.
Install: clawhub.ai/autogame-17/capability-evolver
6. Self-Improving Agent
Self-learning framework. The agent learns from its own interactions and adjusts its responses over time.
16,700 stars on ClawHub, nearly three times the next closest skill. Good for anyone running the same agent daily.
Install: clawhub.ai/xiucheng/xiucheng-self-improving-agent
7. Wacli (WhatsApp)
Command-line interface integration with WhatsApp. Your agent can send messages to third parties, search conversation history, and sync threads. Useful for freelancers and businesses where WhatsApp is the primary client channel.
Install: clawhub.ai/byungkyu/whatsapp-business
