by Mei Lin 68 views

Introduction

In the realm of software development, efficient issue triage is paramount for maintaining a healthy and responsive project. When users report issues, it's crucial to gather sufficient information to understand, reproduce, and ultimately resolve the problem. However, issue reports often lack essential details, leading to delays and frustration. That's where implementing missing information extraction comes into play. This article delves into how we can automate the process of identifying missing information in issue reports, enabling a more structured and efficient triage process. We'll explore the challenges, the solutions, and the benefits of this approach, ensuring a smoother experience for both developers and users.

Context: The Need for Automated Information Extraction

Guys, we've all been there – staring at an issue report that's as clear as mud. It's missing critical details, making it impossible to reproduce the bug or even understand the root cause. This is a common pain point in software development, and it's why we need a better way to handle these situations. The existing system has a foundation with the prompt infrastructure under src/prompts/select-labels/ and a missing-info system prompt at src/prompts/select-labels/system-prompt-missing-info.ts. Our goal is to enhance this system to be more deterministic and machine-parseable, providing a short summary, structured reproduction fields, explicit missing fields, and targeted questions. This will not only save time but also improve the quality of issue resolution.

Feature Request: Missing Info + Structured Extraction

The core of our solution is a feature request that focuses on missing information extraction combined with structured data capture and user-friendly notifications. The idea is to create a system that can intelligently analyze issue reports, identify what's missing, and then communicate this to the user in a clear and helpful way. This involves several key components:

  1. Deterministic Missing Info Prompt: We need a reliable prompt that consistently identifies missing information in a structured format.
  2. Reusable Comment Builder: A tool to generate friendly and informative comments to users, requesting the necessary details.
  3. Handler for Comment and Labels: Logic to automatically post or update comments and apply relevant labels to the issue.

When the system detects missing information, it should automatically apply labels like s/needs-info and s/needs-repro, and post a comment asking for the required details. The comment should be idempotent, meaning it can be updated in place without creating duplicates. This ensures a clean and organized issue thread.

Tasks & Code Snippets: Building the Solution

To bring this feature request to life, we'll break it down into specific tasks, complete with code snippets to illustrate the implementation. Let's dive in!

1. Update the System Prompt: Enhancing Information Extraction

Our first task is to update the system prompt. This is the heart of our information extraction process. The prompt needs to be clear, concise, and deterministic, ensuring consistent results. The goal is to guide the system to evaluate issue reports and determine if they contain sufficient information for reproduction and diagnosis. We will replace the current missing-info prompt with an improved version, optimized for accuracy and structured output.

export const systemPromptMissingInfo = `
You are an expert triage assistant who evaluates if issue reports contain sufficient information to reproduce and diagnose reported problems.
...
`

This updated prompt will serve as the foundation for our missing information extraction process. It instructs the system to act as an expert triage assistant, focusing on the key information needed to resolve issues effectively. The prompt should include specific instructions on the format of the output, ensuring it's machine-parseable and contains the necessary details like a summary, repro steps, missing fields, and targeted questions.

2. Reusable Comment Builder: Crafting User-Friendly Notifications

Next, we need a way to communicate with users in a friendly and informative manner. This is where the reusable comment builder comes in. This tool will generate comments that clearly explain what information is missing and what steps the user can take to provide it. A crucial aspect of this builder is the inclusion of a hidden marker for upsert. This marker allows us to update the comment in place, ensuring we don't clutter the issue thread with multiple requests for the same information.

export function buildNeedsInfoComment(data: MissingInfoPayload): string {
  // ...
}

The buildNeedsInfoComment function takes a MissingInfoPayload object as input, which contains all the necessary information about the missing details. The function then constructs a comment that is easy to understand and actionable. The comment should include a summary of the issue, a list of missing information, and targeted questions to guide the user. By using a reusable comment builder, we ensure consistency and clarity in our communication with users.

3. Handler for Comment and Labels: Automating Triage Actions

Finally, we need a handler to automate the process of posting comments and applying labels. This handler will use the comment builder to generate the appropriate message and then post or update it on the issue. It will also apply labels like s/needs-info and s/needs-repro to indicate the status of the issue. This automation is crucial for streamlining the triage process and ensuring issues are handled efficiently.

export async function upsertNeedsInfoComment(...)
export async function syncNeedsInfoLabels(...)

The upsertNeedsInfoComment function will handle the posting or updating of comments, using the hidden marker to ensure idempotency. The syncNeedsInfoLabels function will apply or remove labels as needed, based on the missing information. This ensures that the issue is correctly categorized and tracked. By automating these actions, we can significantly reduce the manual effort required for issue triage.

Integration Notes: Connecting the Pieces

Now that we've built the individual components, it's time to integrate them into the existing triage flow. This involves wiring the missing-info prompt into the system and handling the model's response appropriately. The integration process is crucial for ensuring the system works seamlessly and efficiently.

Wiring the Missing-Info Prompt

The first step is to wire the missing-info prompt into the triage flow. This involves referencing the template in src/prompts/select-labels/index.ts. This template serves as the entry point for the missing information extraction process. By integrating the prompt into this template, we ensure that it's invoked whenever an issue report needs to be analyzed for missing details.

Handling the Model Response

After the model processes the issue report and generates a response, we need to handle it appropriately. If the response indicates missing information, we'll use the comment builder to create a user-friendly message and post it to the issue. We'll also apply the relevant labels, such as s/needs-info and s/needs-repro. If, on the other hand, the model determines that no information is missing, we'll remove these labels.

This logic ensures that issues are correctly labeled and that users are promptly notified of any missing information. The idempotent comment builder ensures that only one comment is posted per issue, preventing clutter and confusion.

Edge Cases & Acceptance Criteria: Ensuring Quality

To ensure our system is robust and reliable, we need to consider edge cases and define clear acceptance criteria. This helps us identify potential issues and ensure the system meets our quality standards. Let's explore some of the key edge cases and acceptance criteria.

Handling Edge Cases

One edge case we need to consider is when the issue report doesn't include any links. In this case, we should omit the links block in the comment. Another edge case is when the issue report already contains platform information or a repository link. The model should be smart enough not to ask for this information again. By handling these edge cases, we can ensure a more user-friendly and efficient system.

Defining Acceptance Criteria

We also need to define clear acceptance criteria to ensure the system meets our requirements. For example, the model should not ask more than five questions, and these questions should be specific to the issue. If logs are requested, the system should redact any secrets in the tips. We also need to ensure that the correct labels are used (s/needs-info, s/needs-repro) and that the updated prompt compiles and is referenced by the 'missing-info' template. Finally, the system should be idempotent, meaning only one comment is posted per issue and it's updated in place.

By addressing these edge cases and defining clear acceptance criteria, we can ensure the quality and reliability of our missing information extraction system.

Example Model Output: A Glimpse of Success

To illustrate how the system works, let's look at an example of the model's output. This example shows the structured data that the model generates when it identifies missing information in an issue report.

{
  "summary": "Crash when opening settings on Windows 11",
  "repro": { "has_clear_description": true, "has_steps": false, "has_code": false, "links": [] },
  "missing": ["steps", "code"],
  "questions": ["Share a minimal repository or zip that reproduces the crash.", "List the exact steps from app launch to the crash (clicks/menus)."],
  "labels": [{"label": "s/needs-info", "reason": "Steps to reproduce are missing."}, {"label": "s/needs-repro", "reason": "No minimal reproducer provided."}]
}

This output provides a clear summary of the issue, indicates which reproduction steps are missing, and asks targeted questions to guide the user. It also includes the appropriate labels to apply to the issue. This structured output is crucial for automating the triage process and ensuring issues are handled efficiently.

Conclusion: Streamlining Issue Triage with Missing Information Extraction

By automating the process of identifying missing details in issue reports, we can significantly reduce the time and effort required to resolve issues. This not only improves the experience for developers but also ensures users receive timely and effective support. By updating the system prompt, building a reusable comment builder, and creating a handler for comments and labels, we can streamline the triage process and ensure issues are handled efficiently. The example model output demonstrates the power of this approach, providing a clear and structured way to identify missing information and guide users in providing the necessary details.

By addressing edge cases, defining clear acceptance criteria, and integrating the system into the existing triage flow, we can ensure its reliability and effectiveness. The result is a more efficient and user-friendly issue resolution process, benefiting both developers and users alike. So, let's embrace missing information extraction and take our issue triage to the next level!
