OpenCode — My Terminal Pair Programmer

OpenCode is the open-source terminal coding agent I reach for first. It pairs with me inside the terminal — reading files, editing code, running commands — and, crucially, it is model-agnostic: the provider can be switched mid-task without losing the conversation.

Why it earns the first slot

• Terminal-native. It lives where I already work; no context switch to a GUI.
• Model freedom. GLM for cheap iteration, Claude for hard reasoning, DeepSeek for code — switched on the fly.
• Omnirouter synergy. Pointing OpenCode at my own OmniRouter endpoint means the "provider" is actually a load-balanced fleet with failover.
• Fast loop. Small edits, quick questions, test runs — the 30-second tasks that happen fifty times a day.

> add tests for timeout handling, keep the CLI identical

How I use it in the loop

OpenCode owns the inner loop: quick refactors, dependency bumps, "explain this stack trace", draft a function with tests. When a task grows beyond a single sitting — multi-file features, architecture moves — I graduate it to Claude Code for planning, or fan it out to Codex if it parallelizes. Knowing which agent to brief is half of the method.
