The Claude Code cheat sheet.

Every command, pattern, and trick — one page.

Slash Commands
/helpShow all available commands
/add-dir [path]Add a directory to context
/compactSummarise conversation, free context
/clearFresh start (keeps file context)
/modelSwitch model mid-session
/costShow current token cost
/reviewReview recent changes
/initGenerate AGENTS.md for current project
/bugReport a bug to Anthropic
Context Management
►Keep sessions focused — one feature or bug at a time
►Use /compact before context fills, not after
►/add-dir only what's relevant — less is more
►Start new sessions for unrelated tasks
►Reference specific files and line numbers
►Long context = degraded quality. Treat it like RAM.
Prompt Patterns That Work
Plan First
Before writing any code, describe your approach in 3-5 bullet points. Wait for my approval before proceeding.
Fix With Context
In [filename], the function [name] is throwing [exact error]. Here is the stack trace: [paste]. Fix it without changing the function signature.
Feature With Constraints
Add [feature] to [file]. Requirements: [list]. Do not modify [other file]. Follow the existing pattern in [example file].
Refactor Safely
Refactor [function/file] to [goal]. Do not change any public interfaces or break existing tests. Show me the diff before applying.
Git Workflow
git add -A && claude -p "write a conventional commit message for these staged changes"
claude "implement [feature], then stage all changes and write a commit message"
Common Mistakes
►Too broad: "fix my app" — give a specific target
►No errors: paste the actual error, not a description
►No AGENTS.md: the biggest leverage point beginners skip
►Long sessions: context degrades — use /compact
►Blind trust: always read the diff before accepting
