The Agent Settings control which Claude model and thinking level agents use, and how they behave on autonomous tasks. You choose a default agent profile that presets these for every new task, can fine-tune the model per phase, and can set the models used by individual features. These are defaults — you can always override them in the task creation wizard. Screenshot 2026 06 23 At 1 21 30 PM

Default agent profile

An agent profile is a preset configuration of model and thinking level. When you create a new task, the selected profile’s settings are used as the defaults. Choose from:
Whatever profile you choose only sets the defaults for new tasks. You can override the model and thinking level for any individual task in the task creation wizard.

Phase configuration

Beyond the profile, you can customize the model and thinking level for each phase of a task independently:
  • Spec Creation — discovery, requirements, and context gathering.
  • Planning — implementation planning and architecture.
  • Coding — the actual code implementation.
  • QA Review — quality assurance and validation.
For each phase you set a Model and a Thinking Level (which can be Adaptive, or a fixed level such as High or Low). This lets you spend more reasoning where it matters — for example, heavier thinking during Spec Creation and Planning, lighter during Coding and QA.

Other agent settings

Additional configuration for how agents work:
  • Agent Framework — the coding framework used for autonomous tasks.
  • AI Terminal Naming — automatically names terminals based on the commands run (uses Haiku).

Feature model settings

Several features run their own AI, and you can set the model and thinking level for each one separately:
Match the model to the job: reserve Opus with high thinking for complex reasoning (planning, ideation, roadmaps), use Sonnet for balanced everyday work, and let Haiku handle fast, mechanical tasks like commit messages and terminal naming.
