I am using Spec Driven Development approach implemented as a Claude Code plugin since Feb for all mid + size tasks. The idea is to write detailed specs first using agent help doing research and interviewing, decompose the task into smaller subtasks, write detailed spec for each task, implement each task separately. You can restart the session after every step in the workflow and after each subtask implementation since all requirements are materialized in specs. This helps to keep session context focused on a single task at time, improve adherence, reduce cost and allow to implement bigger tasks that are hard to implement with pure plan + code.

Similar with a todo.md in the project which outlines work to be done.. this gets combined with developer and/or user documentation which outlines features and how they're expected to work. I'll iterate with the agent on the planning and documentation through several times until the documentation and plan look good. The only gotcha I've had a couple times is I'll have the testing and spec before implementation and sometimes the agent will try to edit tests rather than making the implementation match spec/tests.

I'm definitely baby sitting the process more than vibe coding, and review each cycle's results. As for languages, mostly TS/JS and Rust with a bit of C# here and there depending on what I need. Claude Code's Opus does a pretty good job with Rust, so for anything personal, I've just gone with it.

Work has been limited to working out specific problems, or a small utility/library that I can pull in, but on my own system, separate from work resources.

Naive question: how much time do you spend doing so vs. Doing the actual work yourself?
