title: XDebug Terminal User Interface DDEV Add-on description: Terminal-native PHP/Xdebug debugger for DDEV — step through code and inspect variables without an IDE status: complete notable:
- lightweight alternative to PhpStorm/VS Code for developers who prefer terminal workflows
- built in 4 sprints over 1 day: ~1,400 lines of Go across 6 packages
- used model tiering throughout: Sonnet for architecture/protocol work, Haiku for mechanical implementation
- semi-scrum sprint structure with explicit demo checkpoints — nothing advanced until current story passed
- screenshot feedback loop: human ran the binary and shared screenshots; agents responded to observed behavior
- each sprint produced a LEARNINGS doc aimed at PHP developers encountering Go concepts
- handoff protocol kept continuity across sessions and models; .agent-handoff/ is public in the repo
- methodology is explicitly documented in DEVELOPMENT_PROCESS.md and reusable for other projects blog_candidate: yes — the development process is the story, not just the tool book_candidate: yes — strong exemplar for the handoff methodology; numbers (4 sprints, 1 day) are concrete drupalcon_comic: no
