Claude Code turns coding agents into multi-surface developer infrastructure

Coding agents are moving from a single chat box into developer infrastructure that touches source control, editors, shells, CI, tool protocols, and team workflows. Claude Code's overview documentation describes an agentic coding tool that reads a codebase, edits files, runs commands, and integrates with development tools across terminal, VS Code, JetBrains, desktop, web, and GitHub-style automation surfaces. It also highlights MCP connections, project instructions through `CLAUDE.md`, skills, hooks, background agents, sub-agents, and an Agent SDK. For agent builders, the practical signal is that coding-agent products should be evaluated by surface coverage and governance: where the agent can run, what repo context it can preserve, which external tools it can inspect, how repeatable workflows are packaged, and whether parallel agents can work without losing reviewability.
