The Complete Claude Tools Guide — Claude Cert Academy

The single biggest upgrade in a Claude workflow usually isn't a prompting trick — it's finally configuring the tools that ship with every paid account. Start at Level 1 and don't skip ahead.

Level 1: The Foundation Everyone Should Set Up

These are not optional. Skip them and you will re-explain context every session forever.

Projects

Projects is the single most under-configured feature in Claude. Without it, every conversation starts from zero — Claude doesn't know your voice, your codebase, or your standards. Allocate 20–30 minutes collecting the context files you repeatedly paste and upload them into a Project.

Claude Skills

If a Project is the environment, a Skill is a saved workflow that runs inside it. A Skill is a markdown file with pre-loaded instructions — for example, a 'Brand Voice' Skill that encodes tone, audience, banned words, and formatting.

To build one: Customize → Skills → enable Skill-Creator. Then tell Claude 'help me build a Skill for process X.'

Memory

Claude accumulates memories about you across conversations. Open Settings → Memory. Delete what's stale. Add the long-lived context you want it to keep.

Migration hack: Ask your previous AI 'I'm migrating this project to Claude — give me a document to transfer the context,' then paste the output into Claude's memory.

Connectors

Connectors wire Claude into the tools you already use — Gmail, Google Drive, Slack, Notion, Calendar, and 50+ others. Settings → Connectors. Plug in whatever you touch daily.

Level 2: Research and Thinking

Deep Research

Activate it and Claude decomposes your query, reads dozens of sources, cross-references them, and returns a cited report. Duration: five to 45 minutes depending on scope. Open the chat, click '+', turn it on.

Extended Thinking

Claude answers fast by default. For strategy, analysis, or multi-step reasoning, you want it slower and more deliberate. Two ways to enable:

Pair heavy reasoning with the strongest model available.

Artifacts

Artifacts are standalone outputs — HTML pages, React components, docs, diagrams, tables — that live as real files you can view, edit, download, and iterate. Ask Claude to 'make this an Artifact' to unlock a much wider surface area: landing pages, dashboards, small apps.

Level 3: Agentic Tools

Claude Cowork

Cowork is desktop-only. Once installed, you hand Claude multi-step jobs that touch your real workflows. Three features that earn their keep daily:

Claude in Chrome

This connector lets desktop Claude launch a task and execute it in the browser without you switching windows. Useful for anything research- or form-driven.

Level 4: Building and Coding

Claude Code

Claude Code is the most capable coding agent available. What it actually does well:

Slash Commands

A built-in command system. The ones worth memorizing:

You can also define your own. Drop a markdown file in .claude/commands/ (project-scoped) or ~/.claude/commands/ (global). The file's contents are the prompt that runs when you invoke it — perfect for /deploy, /test-all, /fix-lint.

CLAUDE.md

A markdown file at the root of any project. Claude Code reads it automatically every session. Inside: coding standards, architectural decisions, file layout, forbidden zones. This is the single biggest quality upgrade most Claude Code users haven't made yet.

This is a Next.js project with TypeScript and Tailwind.

Always use functional components. Never class components.

Run npm run lint before committing.

All API calls go through /lib/api. Don't call APIs directly
from components.

Don't modify /config without approval.

Multi-agent Mode and Subagents

Claude Code can spawn subagents in parallel — one writing tests while another builds the feature, one refactoring while another writes docs. It decides when to spawn them based on task complexity.

How you trigger them: give outcome-oriented prompts, not step-by-step instructions. 'Refactor X and add tests' invites parallelism. 'First do A, then B, then C' does not.

Adopt slash commands, a real CLAUDE.md, outcome-oriented prompts for subagents, and memory hygiene. That combination alone moves Claude Code productivity up a tier.

The Bottom Line

The tools are already included. The bottleneck is not access — it's that nobody sets them up. Dedicate one afternoon wiring up Projects, a Skill, Memory, and a CLAUDE.md in your main repo. The compounding effect starts the next morning.
