What is Claude Code?
Claude Code is Anthropic's agentic coding tool for working directly with software projects. Developers can assign it tasks such as fixing a bug, writing tests, or carrying out a migration. It examines the codebase, proposes or follows a plan, edits files, and runs commands; developers can steer the work and review its changes. It can be used from a terminal, IDE, web, Slack, or mobile apps, with project sessions available across several environments.
What can Claude Code do?
File editing
It can make code changes in project files, with the page showing edits and a summary of the files affected for developer review.
Command execution
It runs commands as part of a coding task, including reproducing an issue and running project checks.
Task planning and clarification
For work that needs more context, Claude Code can build a plan and ask clarifying questions before proceeding.
Multiple work surfaces
Sessions can be steered and reviewed from the terminal, IDE, Slack, or web; the page also lists iOS and Android access.
Long-running tasks
Anthropic describes assigning work that can run for hours or days, including multi-day migrations and other extended coding tasks.
Use Cases
“Investigate an unfamiliar repository”
Ask for an explanation of a codebase to get an overview of its purpose, architecture, components, and key features.
“Fix a production bug”
Provide a reproducible issue, such as duplicate checkout requests, and have Claude Code trace the relevant flow, identify a cause, and propose a code change.
“Add or update tests”
Assign test-writing work for a module and use command execution to run relevant checks as part of the task.
“Carry out a migration”
Delegate a multi-step code migration, clarify requirements during planning, and review progress and edits over an extended session.
