What the research found

A developer's update on his agentic coding workflow now mixing Claude Code, Codex (GPT-5.6 Sol preferred over Opus 4.6 for efficiency) and the open source Pi harness, with context management still central; background reading rather than an urgent change.

Claims and how well the evidence supports them

OpenAI shipped the GPT-5.6 family: Luna, Terra, and Sol 99%
Pi is a minimal open source agent harness 99%
Codex has built-in browser and native multi-agent delegation via worktrees 98%
