Roo Code shut down on May 15, 2026 and its repo is archived, so the first cost move is to a maintained agent: ZooCode (the community fork that keeps Roo's modes) or Cline (the extension Roo was forked from). The levers below carry over. The bill multiplier was the mode system: an Architect pass, a Code pass, and a Debug loop are three separate model conversations for one piece of work, each re-sending context, so putting cheap models on the low-stakes modes and reserving the strong model for Code mode cuts more than any single other change.
ZooCode, like Roo Code before it, lets you configure a different provider/model per mode. Architect and Ask run fine on a budget model; give Code mode the strong model. This alone routinely halves the bill on plan-heavy workflows.
Long exploratory planning chats are the hidden cost center. Front-load the constraints in your first message, get the plan, switch modes. Every extra Architect round-trip re-bills your project context.
Point the agent at the directories that matter instead of letting it roam the whole monorepo. Smaller working sets mean smaller re-sent context on every mode's every message.
Three passes per task is a structural multiplier that per-token billing punishes and capped multipliers exhaust. A flat-rate plan turns the multiplier into a non-event.
The provider-agnostic tactics (prompt caching, retry budgets, batch APIs) are in the general playbook.
No. Roo Code shut down on May 15, 2026 and its GitHub repo is archived, so it gets no fixes or support for new models. The Roo team recommends Cline; ZooCode, a fork the Roo community started, keeps the mode system and per-mode model settings these tactics rely on.
Usually the mode system: if you plan in Architect, implement in Code, and iterate in Debug, you've run roughly three conversations where a single-mode agent ran one. Per-mode model assignment is the built-in fix.
Code mode (in ZooCode now that Roo is shut down): it's where output quality directly becomes your diff. Architect produces plans (cheap models plan adequately with a good prompt), and Debug is iterative enough that a mid-tier model usually suffices.
The structural version of all of this: run Roo Code on a flat monthly price, and the bill stops being a variable to manage. 2-minute Roo Code setup →
