# test
Verify correctness, write tests, validate behavior.
This capability is exercised during the in-progress phase.
## Constraints
| May modify files | yes | Writing test code |
| May run tests | yes | Core activity: running tests |
| May create items | no | Test findings are reported as comments |
| May change status | no | Testing does not approve or close |
## Agent Configuration
```yaml
agent:
name: tester
permissions:
allowed: [read, search, grep, write, edit, bash]
denied: [delete]

## Interaction

before irreversible actions like modifying production code.
