Agents ship faster than anyone can review, so things slip. A steward is a narrow owner for one dimension of your codebase — auth, billing, performance — that watches every change and catches what matters. Add stewards as you grow, from one repo to a whole team.
Other AI reviewers optimize precision, to protect your attention. Stewards assume your agents already fix what review finds, so they optimize the one thing left: missing nothing. You don’t install a steward, you build a fleet, a composable layer for your agent loops and software factories.
If it would benefit from an owner, it will benefit from a steward. Below: real stewards, running in real repos.
Before the agent builds
Ask the event reliability steward about a telemetry plan. It spots the part that needs a test before your agent writes the first diff.
After the diff lands
The same steward reads the changed files, raises the concern that still needs you, then clears the check when the agent proves the fix.

Use a coding agent that supports remote HTTP MCP servers and browser sign-in. Connect it directly to Steward:
https://mcp.steward.fooThe agent reads the server’s current tool descriptions and schemas, proposes a focused steward, and previews it with you before saving.
