The "which coding agent is best" debate has a boring but correct answer: it depends on the task. Each of the big three is excellent, each has a personality, and the cost of switching is low when your tool lets you choose per task. Here's how we think about matching the agent to the job.
The case against picking just one
Standardizing on a single agent feels tidy, but it leaves value on the table. Models differ in how they plan, how aggressively they refactor, how they handle huge contexts, and what they cost per run. If you can assign Claude Code to one card and Gemini to the next, you optimize each task instead of compromising across all of them.
The meta-skill isn't loyalty to one agent — it's knowing which to reach for, and being able to switch in one click.
Claude Code
A strong default for substantial, multi-file work: refactors, feature builds, and anything where careful planning and faithful diffs matter. It tends to be methodical and explains its reasoning, which makes the review step smoother. Reach for it when correctness and code quality outweigh raw speed.
Codex
A capable generalist that's comfortable driving a shell and iterating quickly. Good for well-scoped engineering tasks, test scaffolding, and tight build-run-fix loops where you want momentum. Worth assigning when the task is concrete and you value throughput.
Gemini
Handy for large-context work and quick passes, and a useful second opinion when another agent gets stuck. A reasonable pick for exploration, broad codebase questions, and high-volume routine edits where cost-efficiency matters.
A simple routing heuristic
- Big refactor or new feature you'll review carefully → Claude Code.
- Concrete task with a fast feedback loop → Codex.
- Exploration, large context, or high-volume small edits → Gemini.
- Stuck? Re-dispatch the same task to a different agent — a fresh perspective often breaks the logjam.
Why this works better in one app
Routing only pays off if switching is frictionless. In Command Fleet the agent is a per-task choice with an optional model override, and every run is isolated in its own worktree — so you can fan the same task out to two agents, compare the diffs, and merge the better one. You bring your own subscriptions for all three, so there's no penalty for using whichever fits.
Don't marry an agent. Assemble a crew and assign the work.
