Copilot Code Review Instructions

Repository-wide conventions, the target-branch compatibility policy, coding standards, and FrankenPHP Worker Mode requirements are defined in the root AGENTS.md. Apply that policy in every review; this file covers review behavior only.

Review priorities

Prioritize actionable findings involving:

• incorrect behavior or an unhandled edge case;
• backward compatibility;
• security, input validation, and context-appropriate output escaping;
• request-specific state leaking through globals, static properties, or shared services, including under Worker Mode where one process serves many requests;
• differences between supported database drivers (MySQLi, PostgreSQL, SQLite3, SQLSRV, OCI8);
• missing regression tests, user-guide changes, changelog entries, or upgrade instructions.

Review behavior

• Determine the PR base branch and apply the compatibility policy from AGENTS.md. If the base branch cannot be determined, assume develop and state that assumption.
• Do not report formatting-only issues already enforced by PHP-CS-Fixer.
• Every finding should identify a concrete failure scenario and the affected code.
