## 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.
