Pipe Anything In
Claude Code is Unix-composable. Pipe logs, diffs, or data directly: tail -200 app.log | claude -p "find anomalies"
Cowork + Dispatch
The Desktop app's Dispatch feature lets you control Claude from your phone. Catch up on Slack, manage files, run tasks remotely.
Sub-Agents
Spawn multiple Claude agents working in parallel on different parts of a task. One lead coordinates, assigns, and merges.
/simplify [focus]
Auto-review your recent changes for code quality. Spawns 3 review agents in parallel, aggregates findings, and applies fixes.
/btw [question]
Ask a quick side question without polluting your main conversation thread. Context stays clean.
/voice
Push-to-talk voice dictation. Talk to Claude instead of typing. Great for brainstorming or when your hands are full.
/fast
Toggle fast mode for quick tasks where speed matters more than depth. Snappier responses, lower cost.
/security-review
Analyze your pending changes for security vulnerabilities. Catches injection, auth issues, and data exposure before you ship.
CLAUDE.md Hierarchy
~/.claude/CLAUDE.md loads globally in every session. ./CLAUDE.md at project root loads for that project. ./subdir/CLAUDE.md is additive — both the root and subdir files load together. Subdirs append, they don't override.
Path-Prefixed Rules
Use .claude/rules with path prefixes for surgical behavior triggers — e.g. "when editing anything in src/api/*, follow these patterns." Better than subdir CLAUDE.mds for conditional logic vs. static domain context.
Git Worktrees for Parallel Work
Run multiple Claude agents on isolated branches simultaneously using git worktrees. Each agent gets its own working copy. Merge the best results when done. Use /batch to orchestrate automatically.
Auto Memory
Claude builds its own memory as it works — saving learnings like build commands and debugging insights — without you writing a thing. Run /memory to view and edit what it's saved across sessions.
