WalkthroughA new Protocol Buffers file named Changes
Sequence Diagram(s)sequenceDiagram participant Client participant ProtoSchema Client->>ProtoSchema: Define user_info (full_name, age_years) Client->>ProtoSchema: Define status enum (UNKNOWN, ACTIVE, INACTIVE)Poem
Impact AnalysisIntroduction of new Protocol Buffers message and enum types for user information📢 Medium 🔗 Impacts API A new Protocol Buffers file defines a message type for user information and a status enumeration, making these types available for use in APIs or services that consume this proto definition. This enables new data structures for representing user details and status in systems that use this proto. Test serialization and deserialization of the new message and enum types across supported languages. Verify compatibility with existing consumers and ensure that all enum values and message fields are handled correctly in downstream systems. 🔍 Related Files

🛠️ Refactor suggestion
Package-directory mismatch breaksbuf lint &buf build.
buf expects every file declaringpackage exampletest; to live underexampletest/.
Becausebad.proto sits at repository root (.), CI will fail withPACKAGE_DIRECTORY_MATCH.
Move the file or change thepackage declaration so they match.
-// current location: bad.proto+// preferred: exampletest/bad.proto (move the file)

🤖 Prompt for AI Agents
In bad.proto at line 3, the package declaration 'package exampletest;' does notmatch the file location, causing buf lint and build errors. To fix this, eithermove bad.proto into an 'exampletest/' directory to align with the package nameor change the package declaration to match the current directory (e.g., 'packageexampletest;' to 'package root;' if staying at root). Ensure the packagedeclaration and file path correspond to satisfy buf's PACKAGE_DIRECTORY_MATCHrule.| package exampletest; | ||

PascalCase message names are required – renameuser_info →UserInfo.
Lower-snake message identifiers violate Google & Buf style guides and will be flagged (MESSAGE_NAMES_UPPER_CAMEL_CASE).
Refactor now to avoid cascading code-gen churn later.

In bad.proto at line 5, the message name `user_info` uses lower-snake case whichviolates style guides requiring PascalCase. Rename the message from `user_info`to `UserInfo` to comply with the MESSAGE_NAMES_UPPER_CAMEL_CASE rule and preventfuture code generation issues.| enum status { | ||

🛠️ Refactor suggestion
Enum & value naming do not comply with proto3 conventions.
- Enum identifiers must be PascalCase →
Status. - Enum values must be UPPER_SNAKE and prefixed with the enum name →
STATUS_UNKNOWN,STATUS_ACTIVE,STATUS_INACTIVE.
Fixing this keeps generated code idiomatic and passesENUM_ZERO_VALUE_SUFFIX/ENUM_VALUE_PREFIX.

In bad.proto around lines 10 to 14, rename the enum identifier from lowercase'status' to PascalCase 'Status' and update all enum values to be uppercase withthe enum name as a prefix, changing 'UNKNOWN' to 'STATUS_UNKNOWN', 'ACTIVE' to'STATUS_ACTIVE', and 'INACTIVE' to 'STATUS_INACTIVE' to comply with proto3naming conventions and pass linting rules.
