Highlights ✨

Insiders Mode: Issue Fields Support

Issue field support is now available behind the remote_mcp_issue_fields feature flag, and is enabled automatically in Insiders Mode. This includes listing issue fields, filtering issues by custom field values, and reading or writing issue field values.

### Insiders Mode: CSV Output

CSV output for default list_* tools is now available behind the csv_output feature flag, and is enabled automatically in Insiders Mode. CSV provides a flatter, more compact representation for list-style responses, helping to reduce token usage for large result sets.

### Context Reduction for GitHub Projects

Project item responses have been significantly reduced in size. list_project_items, get_project_item, and update_project_item now return compact project item, content, and field-value shapes instead of full GitHub issue and pull request payloads, cutting unnecessary context while preserving the information agents need.

### Commit Search

A new search_commits tool has been added, allowing agents to search commits directly using GitHub search syntax. This fills a gap between listing repository commits and finding specific commits across debugging, auditing, and release investigation workflows.

### GHAS Alert Pagination

The GHAS alert listing tools now support pagination. list_code_scanning_alerts, list_dependabot_alerts, and list_secret_scanning_alerts can now retrieve beyond the first page of results, avoiding incomplete alert summaries for repositories with larger security backlogs.

### Reliability and Hardening

This release includes several tool reliability improvements, including returning isError for argument validation failures so agents can self-correct, guarding completions requests against malformed params, and ignoring proxy forwarding headers by default when building OAuth resource metadata.
