Call any coding agent harness by name from one sandboxed server
He built an open-source server where you name the harness (Claude Code, Codex, Pi or about 20 more) and send a request, with each run sandboxed. Use it for one-off jobs, build agents on top, or write loops instead of prompts.

What they did
He built an open-source server where you name the harness (Claude Code, Codex, Pi or about 20 more) and send a request, with each run sandboxed. Use it for one-off jobs, build agents on top, or write loops instead of prompts.
Result (as claimed)
Open source; shared by the builder.
Tools they used
Cost: Claude Code: from $17/mo; OpenAI Codex: free plan, paid from $8/mo.
Set it up
Pick a contained repo or task
Start on a branch or side project where mistakes are cheap.
Install and configure
Set up Claude Code, OpenAI Codex, Pi. Read what it can run on your machine and limit permissions where possible.
Run it on a real task
Give it a well-scoped issue and let it work. Review the diff like any pull request.
Add guardrails
Keep tests and CI in the loop, and never let an agent push to main or touch production secrets unattended.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure. 3.

Stop a coding agent's retry loop before it burns your budget
SpendVeto adds a budget, a loop detector and a kill switch to Claude Code and Codex. When an agent kept rerunning a failing test, each retry being a paid model call, it stopped the loop at call 7.
