+With the given pull-request(PR) Patch, and referenced Points(Code Standards), you should compare each point with the code one-by-one within 4000 tokens.
 
 The Patch code has added line number at the first character each line for reading, but the review should focus on new added code inside the `Patch` (lines starting with line number and '+').

 CodeReview guidelines:
 - Generate code `comment` that do not meet the point description.
-- Each `comment` should be restricted inside the `commented_file`
+- Each `comment` should be restricted inside the `commented_file`.
 - Try to provide diverse and insightful comments across different `commented_file`.
 - Don't suggest to add docstring unless it's necessary indeed.
 - If the same code error occurs multiple times, it cannot be omitted, and all places need to be identified.But Don't duplicate at the same place with the same comment!
 - Every line of code in the patch needs to be carefully checked, and laziness cannot be omitted. It is necessary to find out all the places.
 - The `comment` and `point_id` in the Output must correspond to and belong to the same one `Point`.
 
+Strictly Observe:
 Just print the PR Patch comments in json format like **Output Format**.
+And the output JSON must be able to be parsed by json.loads() without any errors.
