name: run-jira description: Fetch a Jira issue and propose an implementation plan based on codebase analysis argument-hint: "" model: sonnet

Fetch the Jira issue $ARGUMENTS from the Datadog Atlassian instance and use it as the basis for a codebase analysis and implementation proposal.

Step 1: Gather Jira issue data

Use the Atlassian MCP tools to fetch the issue. Only request the fields you need to avoid huge responses:

1. Call mcp__atlassian__getJiraIssue with:
   • cloudId: datadoghq.atlassian.net
   • issueIdOrKey: $ARGUMENTS
   • fields: ["summary", "description", "status", "assignee", "issuetype", "comment", "priority"]
2. Extract the title (summary), description, status, assignee, and comments from the response.

If the issue cannot be found, stop and inform the user.

Step 2: Summarize the issue

Present a clear summary of the Jira issue:

• Key: $ARGUMENTS
• Title: the issue summary
• Status: current status
• Assignee: who is assigned
• Description: the full description
• Comments: any relevant context or discussion from comments
• Link: https://datadoghq.atlassian.net/browse/$ARGUMENTS

Step 3: Fetch linked resources

Scan the issue description and comments for links to external resources and fetch them for additional context:

• Datadog notebooks / postmortems (app.datadoghq.com/notebook/<id>): use mcp__datadog-mcp__get_datadog_notebook with the notebook ID
• GitHub PRs (github.com/.../pull/<number>): use gh pr view <number> via Bash
• GitLab commits/pipelines or other URLs: use WebFetch if accessible

This step is critical — linked resources often contain the root cause analysis, timelines, and technical details that the Jira description alone does not capture.

Step 4: Analyze the codebase

Based on the issue requirements and linked resources, explore the codebase to understand:

• Which files and packages are relevant
• Existing patterns and conventions that should be followed
• Dependencies and potential impacts

Use Glob, Grep, and Read tools extensively. For broad exploration, use the Task tool with subagent_type=Explore.

Step 5: Propose an implementation

Enter plan mode with EnterPlanMode and write a detailed implementation plan that includes:

• A breakdown of the changes needed, organized by file
• Any new files that need to be created
• Test strategy
• Potential risks or open questions

Wait for user approval before implementing.
