I always get Claude Code to create a plan unless its trivial, it will describe all the changes its going to make and to which files, then let it rip in a new context.

(Mildly) shameless plug, but you might be interested in a tool I’ve been building: https://github.com/jbonatakis/blackbird

It breaks a spec (or freeform input) down into a structured json plan, then kicks off a new non-interactive session of Claude or codex for each task. Sounds like it could fit your workflow pretty well.

Why use a new context? Or you mean, just accept the plan and it automatically clears the context.
