What is a coding agent?
A coding agent is an AI agent that works in a software project: it reads files, writes and edits code, runs commands and tests, and iterates until a task is done. Claude Code, OpenAI Codex and Cursor's agent are examples. Because they can run tools, they also handle non-coding tasks like browsing and filling forms.
What they do
- Read and search a codebase.
- Plan changes, edit files, run builds and tests.
- Use the terminal, git and project scripts.
- Connect to external tools through MCP or plugins.
- Follow project instructions and skills.
Main examples
| Tool | Where it runs |
|---|---|
| Claude Code | Terminal, IDEs, desktop and web |
| OpenAI Codex | CLI, IDE extension and cloud |
| Cursor | An AI code editor with an agent mode |
Beyond code
Because a coding agent can run tools, it can do repetitive work around a product: research, data cleanup, and with browser access, filling web forms. A launch kit that ships as a repository with instructions turns a coding agent into a launch assistant: the agent reads the playbook and directory list and works through submissions in your browser.
Safety
Coding agents ask permission before running commands or editing files, depending on settings, and can be limited to certain directories and tools. For browser tasks, the agent should stop at payments, passwords and CAPTCHAs.
Example
A founder opens a launch repository in Claude Code and asks it to submit her product to the directories that fit. The agent reads the instructions, checks the catalog, and starts submitting in Chrome, asking her before anything paid.
FAQ
Do coding agents only write code?
No. They can run any tool you give them, including browsers and scripts.
Which coding agent is best?
It depends on your setup; Claude Code, Codex and Cursor are widely used.
Are coding agents safe?
They use permission prompts and sandboxing; review what they do, especially with accounts and payments.
