Decision matrix
Choose the agent by the workflow you need to prove.
Do not start with the most popular repo. Start with the smallest workflow where the agent can succeed or fail visibly.
Best by scenario
What to test first
Best first test: one narrow website flow with a test account.
Best first test: one small issue in a sandbox repository.
Best first test: one repeatable local task with clear logs.
Best first test: one tool-using code agent with minimal dependencies.
Best first test: retrieval and update behavior over repeated sessions.

Workflow fit matrix
| Project | Best for | Depth | Setup | Main risk |
|---|---|---|---|---|
| browser-use | Browser workflows | Focused | Medium | Website fragility |
| OpenHands | Coding agents | Deep | High | Unsafe diffs or shell commands |
| Goose | Local workflows | Broad | Medium | Desktop permissions |
| smolagents | Code agents | Small | Low | You build more around it |

Methodology
How OpenAgent evaluates agent fit
Browser, codebase, local desktop, orchestration, memory, or mixed tool workflow.
Official docs, repository health, license clarity, and dated verification beat marketing claims.
The right agent is the one whose risks you can sandbox, observe, and review.
