Review
Overview¶
The review
tool scans the PR code changes, and generates a list of feedbacks about the PR, aiming to aid the reviewing process.
The tool can be triggered automatically every time a new PR is opened, or can be invoked manually by commenting on any PR:
Note that the main purpose of the review
tool is to provide the PR reviewer with useful feedbacks and insights. The PR author, in contrast, may prefer to save time and focus on the output of the improve tool, which provides actionable code suggestions.

Example usage¶
Manual triggering¶

on any PR:
After ~30 seconds, the tool will generate a review for the PR:
If you want to edit configurations, add the relevant ones to the command:
Automatic triggering¶

[pr_reviewer]
section contains the configurations for thereview
tool you want to edit (if any).

Adding PR labels
You can enable\disable the review
tool to add specific labels to the PR:
enable_review_labels_security | If set to true, the tool will publish a 'possible security issue' label if it detects a security issue. Default is true. |
enable_review_labels_effort | If set to true, the tool will publish a 'Review effort [1-5]: x' label. Default is true. |
Auto-approval
If enabled, the review
tool can approve a PR when a specific comment, /review auto_approve
, is invoked.
enable_auto_approval | If set to true, the tool will approve the PR when invoked with the 'auto_approve' command. Default is false. This flag can be changed only from a configuration file. |

Usage Tips¶
General guidelines
The review
tool provides a collection of configurable feedbacks about a PR.
It is recommended to review the Configuration options section, and choose the relevant options for your use case.
Some of the features that are disabled by default are quite useful, and should be considered for enabling. For example:
require_score_review
, require_soc2_ticket
, and more.
On the other hand, if you find one of the enabled features to be irrelevant for your use case, disable it. No default configuration can fit all use cases.
Automation
When you first install Qodo Merge app, the default mode for the review
tool is:
review
tool will run automatically on every PR, without providing code suggestions.
Edit this field to enable/disable the tool, or to change the configurations used.
Possible labels from the review tool
The review
tool can auto-generate two specific types of labels for a PR:
- a
possible security issue
label that detects if a possible security issue exists in the PR code (enable_review_labels_security
flag) - a
Review effort [1-5]: x
label, where x is the estimated effort to review the PR (enable_review_labels_effort
flag)
Both modes are useful, and we recommended to enable them.
Extra instructions
Extra instructions are important.
The review
tool can be configured with extra instructions, which can be used to guide the model to a feedback tailored to the needs of your project.
Be specific, clear, and concise in the instructions. With extra instructions, you are the prompter. Specify the relevant sub-tool, and the relevant aspects of the PR that you want to emphasize.
Examples of extra instructions:
Use triple quotes to write multi-line instructions. Use bullet points to make the instructions more readable.Auto-approval
Qodo Merge can approve a PR when a specific comment is invoked.
To ensure safety, the auto-approval feature is disabled by default. To enable auto-approval, you need to actively set in a pre-defined configuration file the following:
(this specific flag cannot be set with a command line argument, only in the configuration file, committed to the repository)After enabling, by commenting on a PR:
Qodo Merge will automatically approve the PR, and add a comment with the approval.You can also enable auto-approval only if the PR meets certain requirements, such as that the estimated_review_effort
label is equal or below a certain threshold, by adjusting the flag:
