Sol Loves to Cheat
Tried to automate my dev flow, hit 94% on Terminal Bench 2.1, then discovered GPT-5.6 Sol starting to cheat.
I’ve been running a “spec-driven” development flow for the past ~year.
Before asking an LLM to do something, I first ask it to draft a doc for what it needs to do.
I use this strategy for feature development, greenfield projects, debugging, you name it.
The pattern works for me, but it’s a bit repetitive.
The idea was straightforward: I’d create a supervisor agent, that would run a “spec-driven process” by delegating to worker subagents who would actually write the docs, do the work, etc.
Note: when trying to do this with vanilla Codex or Claude Code, it would somewhat work, but the default prompts are catered to a user much more so than a “supervisor”
I hypothesized that the supervisor agent need only have the ability to read files and call workers, because that’s what I do.
Rather than rebuild a coding harness for the workers, I looked at Pi, OpenCode, and Codex’s App Server.
I’d been using Codex for quite awhile, so I decided to give app-server a spin. The other options are cool, you should check them out.
