The data includes:79- Issue number, title, body/description80- Labels, state, author, assignees, milestone, timestamps8182Use `jq` to filter and analyze the data:83~~~bash84# Get count of issues85jq 'length' /tmp/gh-aw/issues-data/issues.json8687# Get issues with a specific label88jq '[.[] | select(.labels | any(.name == "bug"))]' /tmp/gh-aw/issues-data/issues.json89~~~9091### Step 2: Analyze Relationships9293Examine the issues to identify potential parent-child relationships. Look for:94951. **Feature with Tasks**: A high-level feature request (parent) with specific implementation tasks (sub-issues)962. **Epic Patterns**: Issues with "[Epic]", "[parent]" or similar prefixes that encompass smaller work items973. **Bug with Root Cause**: A symptom bug (sub-issue) that relates to a root cause issue (parent)984. **Tracking Issues**: Issues that track multiple related work items995. **Semantic Similarity**: Issues with highly related titles, labels, or content that suggest hierarchy1006. **Orphan Clusters**: Groups of 5 or more related issues that share a common theme but lack a parent issue101102### Step 3: Make Linking Decisions103104For each potential relationship, evaluate:105- Is there a clear parent-child hierarchy? (parent should be broader/higher-level)106- Are both issues in a state where linking makes sense?107- Would linking improve organization and traceability?108- Is the relationship strong enough to warrant a permanent link?109110**Creating Parent Issues for Orphan Clusters:**111- If you identify a cluster of **5 or more related issues** that lack a parent issue, you may create a new parent issue112- The parent issue should have a clear, descriptive title starting with "[parent] " that captures the common theme113- Include a body that explains the cluster and references all related issues114- Use temporary IDs (format: `aw_` + 3-8 alphanumeric characters) for newly created parent issues115- After creating the parent, link all related issues as sub-issues using the temporary ID116117**Constraints:**118- Maximum 5 parent issues created per run119- Maximum 50 sub-issue links per run120- Only create a parent issue if there are 5+ strongly related issues without a parent121- Only link if you are absolutely sure of the relationship - when in doubt, don't link122- Prefer linking open issues123- Parent issue should be broader in scope than sub-issue124125### Step 4: Create Parent Issues and Execute Links126127**For orphan clusters (5+ related issues without a parent):**1281. Create a parent issue using the `create_issue` tool with a temporary ID:129   - Format: `{"type": "create_issue", "temporary_id": "aw_XXXXXXXX", "title": "[parent] Theme Description", "body": "Description with references to related issues"}`130   - Temporary ID must be `aw_` followed by 3-8 alphanumeric characters (e.g., `aw_abc123`, `aw_Test123`)1312. Link each related issue to the parent using `link_sub_issue` tool with the temporary ID:132   - Format: `{"type": "link_sub_issue", "parent_issue_number": "aw_XXXXXXXX", "sub_issue_number": 123}`133134**For existing parent-child relationships:**135- Use the `link_sub_issue` tool with actual issue numbers to create the parent-child relationship136137### Step 5: Done138139After completing your analysis and any linking actions, if no action was needed, call the `noop` tool with a summary:140~~~json141{"noop": {"message": "Analyzed N issues - no new parent-child relationships identified"}}142~~~143144If you did take action, you do not need to call noop. Simply finish after executing all links.145146## Important Notes147148- Only link issues when you are absolutely certain of the parent-child relationship149- Be conservative with linking - only link when the relationship is clear and unambiguous150- Prefer precision over recall (better to miss a link than create a wrong one)151- Consider that unlinking is a manual process, so be confident before linking152- **Create parent issues only for clusters of 5+ related issues** that clearly share a common theme153- When creating parent issues, include references to all related sub-issues in the body154155**Important**: If no action is needed after completing your analysis, you **MUST** call the `noop` safe-output tool with a brief explanation.
