Ergun Erdogmus contributed to the vercel/vercel repository by developing and refining CLI tools and metrics infrastructure over a three-month period. He implemented features such as the Vercel Activity CLI, enabling users to list and filter events with robust pagination and JSON output, and enhanced the metrics schema for improved reliability and developer experience. Using TypeScript, Ergun focused on API development, CLI development, and data management, ensuring schema alignment and usability improvements. He also streamlined CLI logs commands by deprecating outdated flags and clarifying advanced filtering, resulting in a more intuitive interface and maintainable codebase, supported by comprehensive unit testing.
In April 2026, the team delivered a CLI UX refinement for logs in vercel/vercel: deprecated the --search flag in vc logs and clarified the --query flag to support advanced filter syntax, with help text and examples updated accordingly. The change preserves full functionality while hiding the deprecated flag from help output, aligning with usage analytics that show --query as the dominant flag. Code changes were implemented in the CLI command surface, and all related tests were executed and passed. This work reduces confusion, shortens learning curve for users, and improves maintainability of the CLI surface.

March 2026: Delivered the Vercel Activity CLI feature that enables listing user and team events from the Vercel Events API with robust filtering, pagination, and JSON output. Implemented the 'vercel activity' command with 'list' and 'types' subcommands, auto-scoping to the linked project by default, and support for team-wide events via --all. Refactored common time-range utilities into a reusable time-utils module and wired telemetry and unit tests for reliability. This release enhances observability, accelerates incident reviews, and improves audit capabilities with minimal impact to security and permissions. Tech and business value: improved event visibility, faster debugging, and reuse of utilities across commands.
