Author: login: cahaseler
Labels: name: released
Created: 2025-05-15T14:33:52Z | Merged: 2025-05-15T17:06:59Z

This PR adds the ability to pass additional context information (like PR and issue details from GitHub) to Claude when generating changelogs. This results in more comprehensive and user-friendly release notes.

## Changes

- Added  option to the  type to accept PR/issue data
- Updated the default prompt template with conditional sections for the additional context
- Modified  to handle and process the additional context
- Added comprehensive tests for the new functionality
- Created detailed examples showing how to use this feature in GitHub Actions
- Updated documentation with usage instructions

## Examples

The PR includes a full example GitHub Actions workflow that demonstrates:

- How to extract PR and issue information from commit messages
- How to collect detailed metadata using GitHub CLI
- How to format this data for use with the plugin
- How to integrate it all in your semantic-release configuration

## Testing

All tests pass with the new implementation, including specific tests for the additional context feature.

 You can customize this template to match your project's needs.
 
+### Using Additional Context
+
+The plugin supports providing additional context information to enrich the generated release notes. This context is passed to Claude Code CLI along with the commit information, allowing it to generate more comprehensive and informative release notes.
+
+Examples of additional context you might want to include:
+- Pull request information (numbers, titles, URLs)
+- Issue details (numbers, titles, URLs)
+- Contributors
+- API changes
+- Sprint/milestone data
+
+To use this feature, provide an `additionalContext` object in your configuration:
+
+```json
+{
+  "plugins": [
+    "@semantic-release/commit-analyzer",
+    ["semantic-release-claude-changelog", {
+      "additionalContext": {
+        "pullRequests": [

+    "@semantic-release/github"

+# Additional Context for Changelog Generation
+
+This directory contains examples of how to provide additional context to the `semantic-release-claude-changelog` plugin to enhance your generated release notes.
+
+## Why Use Additional Context?
+
+When generating changelogs, it's often useful to include more information than just commit messages. Additional context such as:
+
+- Pull request details (titles, authors, labels, descriptions)
+- Issue information (titles, status, labels, descriptions)
+- Contributors (names, email addresses)
+- Repository metadata
+- API changes or breaking changes
+- Sprint/milestone data
+
+This enriches your changelogs and makes them more useful to your users, providing a more complete picture of what changed and why.
+
+## Usage
+
+The plugin accepts an `additionalContext` option that can contain any structured data that might be useful for your changelog. This data is passed to Claude Code CLI to help it generate more meaningful release notes.
+
+### Example GitHub Actions Workflow
+
+The [github-workflow.yml](github-workflow.yml) file demonstrates how to:
+
+1. Collect comprehensive information about pull requests and issues related to the release
+2. Extract contributor information from the commit history
+3. Format all data as a structured JSON object
+4. Pass it to the semantic-release plugin
+
+#### Key Features of the Example Workflow
+
+- **Advanced PR Detection**: Identifies PRs referenced in commit messages using multiple patterns:
+  - PR numbers in subject lines (#123)
+  - Merge commit references (Merge pull request #123)
+  - Other common PR reference formats (PR: #123, pull-request: #123)
+
+- **Comprehensive Issue Linking**: Finds issues mentioned in commit messages with patterns like:
+  - Closes #123
+  - Fixes #123
+  - Resolves #123
+  - Addresses #123
+  - Issue #123
+  - Ref #123
+
+- **Rich Metadata**: Collects detailed information using GitHub CLI:
+  - For PRs: number, title, URL, labels, author, body, base/head branches, merge date
+  - For issues: number, title, URL, labels, author, body, state, creation date
+  - For contributors: name and email address
+
+- **Robust Error Handling**: Includes checks and fallbacks to ensure the workflow succeeds even if:
+  - No previous tags exist
+  - Some PRs or issues are not accessible
+  - Referenced issues are in external repositories
+
+### Configuration Example
+
+The [releaserc.json](releaserc.json) file shows how to configure semantic-release to use the additional context in the Claude prompt, including:
+
+1. A custom template that demonstrates how to format the additional context
+2. Conditional sections that only appear when data is available
+3. Special formatting for different types of information
+
+## Modifying the Template
+
+You can also customize the prompt template to make better use of the additional context. The default template includes a conditional section for additional context, but you can modify it to emphasize specific information.
+
+Example of a custom template that highlights pull requests:
+
+```javascript
+const config = {
+  plugins: [
+    ["semantic-release-claude-changelog", {
+      promptTemplate: `
+Generate release notes for version {{version}} of {{repoName}}.
+
+Here are the commits:
+\`\`\`json
+{{commits}}
+\`\`\`
+
+{{#additionalContext}}
+Pull Requests in this release:
+{{#pullRequests}}
+- #{{number}}: {{title}} ({{url}})
+{{/pullRequests}}
+
+Issues addressed:
+{{#issues}}
+- #{{number}}: {{title}} ({{url}})
+{{/issues}}
+{{/additionalContext}}
+
+Format the notes with markdown headings grouping similar changes.
+      `,
+      additionalContext: {
+        // Your context here
+      }
+    }]
+  ]
+}
+```
+
+## Best Practices
+
+1. **Structured Data**: Provide context as structured JSON objects rather than raw text
+2. **Minimal Data**: Include only relevant information that will help generate better release notes
+3. **Template Customization**: Adjust the prompt template to best utilize the additional context

* [nitpick] Consider using a dedicated templating engine or helper functions to manage conditional sections rather than relying on a regex replace. This can make the template processing more robust against changes in the template format.

body: I fixed the CodeQL alerts by replacing the regex patterns with safer string operations. The changes include:

1. Replacing the regex-based template processing with explicit string manipulation:
   - Using  and  operations to find and replace template blocks
   - Adding multiple fallback options for edge cases
   - Maintaining the same functionality with improved security

2. Adding better error handling:
   - Proper handling of missing end tags in templates
   - Safe fallbacks when expected patterns aren't found
   - More defensive code that handles unexpected template formats

The changes should resolve the polynomial regular expression (ReDoS) vulnerability warnings while preserving all the functionality.
