Engineering
by Anthropic
Coding, review, and debugging skills that plug into an existing development workflow rather than replacing it.
What’s in the bundle
- Code review focused on correctness and the failure case, not style
- Debugging skills that reason from a stack trace to a hypothesis
- Refactoring help that preserves behaviour
- Test-writing skills that cover the branch that actually breaks
What you can do with it
- Review a diff and get the defects ranked by consequence
- Work from an error to a root cause and a proposed fix
- Backfill tests on a module that was shipped without them
What it doesn’t do
It reasons over the code you give it. It has no view of your CI, your production behaviour, or the parts of the system you did not paste in — which is exactly where the interesting bugs tend to live.
Where it runs
Anthropic built Engineering as a Cowork plugin, which runs inside Claude Desktop. We rebuilt it as MCP-compatible skills, so the same bundle works in Claude, ChatGPT, Cursor, Claude Code, and Agentman over one connection.
