practice makes claude perfect

 |
Note: Custom slash commands have been merged into skills. Files in
.claude/commands/still work, but skills (.claude/skills/) are recommended as they support additional features like supporting files, invocation control, and subagent execution.
- Skills - Reusable knowledge, workflows, and slash commands that Claude can load on-demand or you invoke with
/skill-name - Agents - Custom agents in
.claude/agents/with their own name, color, tools, permissions, and model — usable as default main agent ("agent"in settings.json) or as isolated subagents via the Task tool - Memory - Persistent context via CLAUDE.md files and
@pathimports that Claude sees every session - Rules - Modular topic-specific instructions in
.claude/rules/*.mdwith optional path-scoping via frontmatter - Hooks - Deterministic scripts that run outside the agentic loop on specific events
- MCP Servers - Model Context Protocol connections to external tools, databases, and APIs
- Plugins - Distributable packages that bundle skills, subagents, hooks, and MCP servers
- Marketplaces - Host and discover plugin collections
- Sandbox - File and network isolation runtime that improves safety while reducing permission prompts
- Output Styles - Configurable response tone and format — Explanatory, Learning, or Custom
- Settings - Hierarchical configuration system for Claude Code behavior (37 settings, 84 env vars)
- Permissions - Fine-grained access control for tools and operations with wildcard syntax
Extension Overview: See Extend Claude Code for when to use each feature and how they layer together.
■ Workflows
- Claude.md should not exceed 150+ lines. (still not 100% guaranteed)
- use commands for your workflows instead of agents
- have feature specific subagents (extra context) with skills (progressive disclosure) instead of general qa, backend engineer.
- /memory, /rules, constitution.md does not guarantee anything
- do manual /compact at max 50%
- always start with plan mode
- subtasks should be so small that it can be completed in less than 50% context
- vanilla cc is better than any workflows with smaller tasks
- commit often, as soon as task is completed, commit.
■ Utilities
- iTerm terminal instead of IDE (crash issue)
- Wispr Flow for voice prompting (10x productivity)
- claude-code-voice-hooks for claude feedback
- status line for context awareness and fast compacting
- git worktrees for parallel development
- /permissions with wildcard syntax (
Bash(npm run *),Edit(/docs/**)) instead of dangerously-skip-permissions - /sandbox to reduce permission prompts with file and network isolation
- output styles: use Explanatory when learning a new codebase, Learning for coaching
- /keybindings to remap any key, settings live reload
■ Debugging
- /doctor
- always ask claude to run the terminal (you want to see logs of) as a background task for better debugging
- use mcp (claude in chrome, playwright, chrome dev tool) to let claude see chrome console logs on its own
- provide screenshots of the issue
- RPI
- Boris Feb26 workflow
- Ralph plugin with sandbox
- Human Layer RPI - Research Plan Implement
- AgentOs - 2026 its overkill (Brian Casel)
- Github Speckit
- GSD - Get Shit Done
- OpenSpec OPSX
- Superpower
- Andrej Karpathy Workflow
- Creator of Clawd Bot Workflow
| Component | Role | Example |
|---|---|---|
| Command | Entry point, user interaction | /weather-orchestrator |
| Agent | Orchestrates workflow with preloaded skills | weather agent |
| Skills | Domain knowledge injected at startup | weather-fetcher, weather-transformer |
When to use: Multi-step workflows • Domain-specific knowledge injection • Sequential tasks • Reusable components
Why it works: Progressive disclosure • Single execution context • Clean separation • Reusability
See weather-orchestration-architecture for implementation details.
