# Implementation Settings

This page is for maintainers tuning `/prflow:implement` and same-checkout verification coordination.

| **Setting**                                           | **Type and accepted values**              | **Fallback or scaffold**                                      | **Tier and security note**                                                                                                                   | **Example**                              |
| ----------------------------------------------------- | ----------------------------------------- | ------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------- |
| `prflow_implement.effort`                             | `low`, `medium`, `high`, `xhigh` or `max` | Scaffold: `low`; absent uses the session or workflow fallback | Local and cloud implementation. Higher values can increase cost and latency.                                                                 | `"effort": "low"`                        |
| `prflow_implement.implement_pr_state`                 | `ready_for_review` or `draft`             | `ready_for_review`; invalid values also publish               | Implementation. `draft` leaves the completed pull request for a human to publish. PRFlow never merges it.                                    | `"implement_pr_state": "draft"`          |
| `prflow_implement.update_branch_checkpoints`          | Boolean                                   | `true`; only an explicit false disables                       | Implementation and pushed fix-loop checkpoints. Merges the configured base into the feature branch at defined boundaries.                    | `"update_branch_checkpoints": true`      |
| `prflow_implement.stall_backstop.enabled`             | Boolean                                   | `true`; unrecognized values enable                            | Cloud implementation. When false, an interim run can end without an automatic resume or loud failure.                                        | `"enabled": true`                        |
| `prflow_implement.stall_backstop.max_resume_attempts` | Integer zero or greater                   | `2`; invalid values use `2`                                   | Cloud implementation. `0` detects and fails without resuming. Each resume can incur another run.                                             | `"max_resume_attempts": 2`               |
| `prflow.attribute_commits_to_triggerer`               | Boolean                                   | Runtime and scaffold: `false`                                 | Cloud writer jobs. Applies only to verified human users and changes Git metadata, not the push credential. Trigger-time and post-merge-only. | `"attribute_commits_to_triggerer": true` |
| `verification_flight.enabled`                         | Boolean                                   | `true`                                                        | Local implementation and inline review-and-fix. Disabling reuse does not turn a missing or stale record into a pass.                         | `"enabled": true`                        |
| `verification_flight.lease_seconds`                   | Integer zero or greater                   | `900`                                                         | Reserved for future use. Changing this setting has no effect in the current release.                                                         | `"lease_seconds": 900`                   |
| `verification_flight.wait_timeout_seconds`            | Integer zero or greater                   | Scaffold: `600`                                               | Reserved for future use. Changing this setting has no effect in the current release.                                                         | `"wait_timeout_seconds": 600`            |

Provider and model overrides for implementation are documented in [Providers](/docs/configuration/providers). Implementation tool grants are documented in [Tool Permissions](/docs/configuration/tool-permissions).
