The Core Problem: Claude's Context Conundrum in GitHub Workflows

When we first integrated Claude into our GitHub Workflow using a .github/workflows/claude.yml file, the idea was brilliant: automate tasks, assist with code reviews, and streamline various development processes simply by mentioning @claude. However, a perplexing issue quickly emerged: even when properly triggered, Claude seemed to operate in a vacuum. It was as if it heard the call but couldn't see the room it was in. The core problem was glaringly obvious yet deceptively simple: Claude was unable to recognize the critical instructions and context embedded within GitHub Issues and Pull Requests. This wasn't due to a lack of intelligence on Claude's part, but rather a missing link in how information was being fed to it by our workflow. Think of it like giving someone a task without telling them what the task is about or where to find the relevant information. It's a recipe for confusion and inefficiency.

Specifically, the existing prompt within our workflow was failing to pass vital information to Claude. This meant that when Claude was activated, it simply didn't have access to the full scope of what was happening. It couldn't see the Issue's title and detailed body, which often contain the most crucial descriptions of the problem or feature request. It was blind to all the comments and discussions that followed, missing out on crucial clarifications, debates, and additional requirements that naturally evolve in a collaborative environment. And perhaps most critically for code-related tasks, Claude was unable to access the Pull Request's diff, meaning it couldn't review the actual code changes that were proposed. Imagine asking an AI to review code without showing it the code itself! This absence of complete context rendered Claude largely ineffective for many of the tasks we hoped it would automate or assist with, from generating sensible responses to creating relevant pull requests. Without this foundational issue recognition and PR understanding, Claude's utility was severely limited, impacting our overall developer productivity and the promise of efficient GitHub Workflow automation. We knew a robust solution was needed to bridge this information gap and truly unleash Claude's potential.

The Game-Changing Solution: Empowering Claude with `gh` Command Context

After identifying the frustrating information gap, we set out to find a solution that would provide Claude with all the context it needed to truly excel in our GitHub Workflow. The answer lay in a simple yet incredibly powerful tool: the GitHub CLI (gh) command. This command-line interface allows us to interact with GitHub directly from our workflow, fetching detailed information about issues, pull requests, and more. By explicitly instructing Claude to use gh to gather this context before starting any task, we've transformed its capabilities from a limited assistant to an informed and intelligent collaborator.

Our solution involves a strategic modification to the .github/workflows/claude.yml file, specifically within the prompt section. We've added a series of steps that guide Claude to first collect all relevant information using gh commands, ensuring it has a holistic view of the situation. This isn't just about dumping data; it's about creating a structured workflow for Claude itself, guiding it to understand its surroundings before acting. This critical change addresses the fundamental problem of issue recognition and PR understanding, making Claude significantly more effective and reliable. The power of this approach lies in its simplicity and its ability to give Claude the same level of context a human developer would have when tackling an issue or reviewing a pull request. This proactive context gathering is paramount for any GitHub Workflow automation involving AI, ensuring that Claude's actions are always informed and aligned with the project's needs. This enhancement significantly boosts developer productivity by reducing misunderstandings and the need for manual corrections, allowing developers to trust Claude with more complex tasks.

Understanding the Workflow Changes: A Deep Dive into Claude's New Smarts

To make Claude a true context-aware powerhouse within our GitHub Workflow, we introduced several key modifications to the .github/workflows/claude.yml file. These changes are designed to systematically provide Claude with all the necessary information, enabling precise issue recognition and PR understanding. Let's break down each component:

Context Variables for Precision: The very first step was to equip Claude with fundamental identifiers. We added specific context variables that are automatically populated by GitHub's event payload:
```
REPOSITORY: ${{ github.repository }}
EVENT_TYPE: ${{ github.event_name }}
ISSUE_NUMBER: ${{ github.event.issue.number }}
PR_NUMBER: ${{ github.event.pull_request.number }}
```
These variables (REPOSITORY, EVENT_TYPE, ISSUE_NUMBER, PR_NUMBER) act as Claude's compass, telling it exactly where it is and what kind of event triggered it. Knowing the repository, the event type (e.g., issue_comment, pull_request_review_comment), and crucially, the specific issue or PR number, allows Claude to target its information gathering precisely. This foundational step is crucial because it ensures that subsequent gh commands retrieve data for the correct context, eliminating any ambiguity about which issue or PR Claude should be focusing on. It’s like giving Claude a proper address before asking it to look something up.
Issue-Related Events: Comprehensive Context Collection: For events related to issues (like an issue being opened or a comment being added to an issue), Claude now executes a powerful command:
```
gh issue view $ISSUE_NUMBER --comments
```
This single command is a game-changer. gh issue view $ISSUE_NUMBER retrieves the full title and body of the issue, which often contains the most detailed problem description, user stories, or feature requirements. The --comments flag is equally vital, as it fetches all associated comments and discussions. This means Claude isn't just seeing the initial problem statement; it's getting the entire conversation, including clarifications, additional requirements, design discussions, and any previous attempts at resolution. This comprehensive view is critical for deep issue recognition and ensures Claude understands the full historical context and evolution of the problem. It prevents Claude from making assumptions based on incomplete information, leading to more accurate and helpful responses or actions. Without this, Claude would be missing out on all the valuable human interaction and refinement that shapes an issue's true scope.
PR-Related Events: Code and Discussion at a Glance: When the workflow is triggered by PR-related events (such as a pull request being opened, reviewed, or commented on), Claude is instructed to run two distinct gh commands:
```
gh pr view $PR_NUMBER --comments
gh pr diff $PR_NUMBER
```
First, gh pr view $PR_NUMBER --comments provides Claude with the PR's title, its descriptive body, and all review comments and discussions. Similar to issues, this ensures Claude understands the why behind the PR, the proposed solution, and any feedback or ongoing debates. This is essential for a holistic PR understanding, allowing Claude to engage meaningfully in code reviews or provide relevant suggestions. But the true magic for PRs comes with the second command: gh pr diff $PR_NUMBER. This command fetches the actual code changes – the difference (diff) between the base branch and the PR branch. For an AI tasked with code review, suggesting improvements, or even implementing changes, having direct access to the diff is absolutely indispensable. It's the equivalent of a human reviewer getting to see the exact lines of code that have been added, modified, or deleted. This direct access to the code context elevates Claude's capabilities dramatically, allowing it to perform more sophisticated analyses, identify potential bugs or stylistic inconsistencies, and propose truly insightful improvements. It bridges the gap between understanding the intent of the PR and seeing its tangible implementation.

A Clear and Explicit Workflow for Claude: Beyond just providing the commands, we've structured the prompt to give Claude a clear, step-by-step instruction set for its work:

## FIRST STEP: Gather Context
Before starting any work, you MUST gather complete context by running the appropriate commands:

### For Issue-related events (issues, issue_comment):
```bash
gh issue view $ISSUE_NUMBER --comments

This will show you the issue title, body, and ALL comments to understand the full context.

For PR-related events (pull_request_review_comment, pull_request_review):

gh pr view $PR_NUMBER --comments
gh pr diff $PR_NUMBER

This will show you the PR title, body, ALL comments, AND the code changes.

Task Instructions

After gathering the full context above:

Read and understand ALL comments and discussions
For PRs, review the code changes in the diff
Execute the requested task based on the complete context
When you complete an implementation task, create a pull request using gh pr create command
- Create a descriptive PR title in English using semantic commit format
- Write the PR body in Japanese with clear description of changes
- Include "fixes #" if there's a related issue

This explicit instruction block serves multiple purposes. First, it *forces Claude to prioritize context gathering* as its absolute first action, ensuring it doesn't jump to conclusions. Second, it clearly outlines the sequence of operations: *read, review, then execute*. This systematic approach significantly improves the reliability and quality of Claude's output. By instructing Claude to "Read and understand ALL comments and discussions" and "review the code changes in the diff" for PRs, we're essentially training it to mimic the best practices of a human developer. It's not just running commands; it's being guided to *process and synthesize* the information before attempting to solve the problem or respond to the request. The final instructions for creating a pull request (`gh pr create`), complete with guidelines for semantic commit format and clear descriptions, further ensure that Claude's automated contributions are high-quality and integrate seamlessly into our existing development standards. This entire revised prompt transforms Claude from a tool that *reacts* to one that *understands* and *acts intelligently* within our *GitHub Workflow*, truly boosting our *developer productivity* and the efficacy of our *AI automation*.

Why This Matters: The Impact on Developer Productivity and Workflow Efficiency

This seemingly small fix to Claude's context gathering in GitHub Workflows actually has a profound impact on our overall developer productivity and the efficiency of our development cycles. It's not just about Claude understanding a bit better; it's about unlocking a new level of AI automation and collaboration that previously felt out of reach. When Claude gains comprehensive issue recognition and PR understanding, the benefits ripple throughout the entire team.

First and foremost, reduced misunderstandings and rework are a huge win. Before this fix, Claude might have attempted tasks based on incomplete information, leading to irrelevant suggestions, incorrect code snippets, or even pull requests that didn't fully address the problem. This meant developers had to spend time clarifying, correcting, or even discarding Claude's output, effectively negating the supposed time savings of AI assistance. Now, with the gh command providing the full context – including issue descriptions, all comments, and the PR diff – Claude's contributions are far more accurate and relevant. This translates directly into less time spent on iterative corrections and more time dedicated to actual development, significantly boosting developer productivity.

Secondly, faster and more reliable automated tasks become a reality. Imagine Claude being able to automatically draft comprehensive PR descriptions based on the actual code changes and linked issue discussions. Or, consider its ability to provide more insightful code review comments by comparing the proposed changes against the original issue's requirements and previous discussions. This level of informed automation accelerates many routine yet time-consuming tasks. For instance, if an issue requires a small code change, Claude can now, with full context, generate a pull request that correctly addresses the issue, includes relevant tests, and follows our semantic commit guidelines – all with minimal human oversight. This kind of seamless GitHub Workflow automation transforms Claude from a novelty into an essential tool, allowing our human developers to focus on higher-level problem-solving and innovation rather than repetitive tasks.

Moreover, this enhancement fosters a smoother development experience and better team collaboration. When an AI assistant consistently provides useful and context-aware help, it builds trust within the team. Developers are more likely to leverage Claude for assistance, knowing that its input will be intelligent and relevant. This can lead to quicker feedback loops, especially in large projects with many contributors. Claude can act as an always-on
