Nano, Supervisor, and Decision models

Usage

Name sessions with nano

Configure nano to generate titles for unnamed sessions without changing the model used for coding. Kent generates a title after the first response and any tool work it starts have completed. Automatic naming leaves existing names unchanged.

Choose an existing connection and an explicit nano model:

[nano]
connection = "subscription"
model = "gpt-6-luna"

For a local model whose context window Kent cannot determine, also set model_context_window to its actual token limit.

Set nano.features.session_naming = false to disable automatic naming. Nano settings follow the normal configuration precedence, so a worktree can select another model or disable naming.

Review answers with the supervisor

The supervisor checks completed answers and supplies suggestions that the coding agent can apply in a follow-up. The answer is visible without waiting for review.

By default, the supervisor runs after answers that include successful file edits and uses the coding agent’s model. Set reviewer.model to choose another model, or reviewer.frequency = "all" to include answers without file edits. Set the frequency to "off" to disable it. Use /supervisor to toggle it during a session.

[reviewer]
frequency = "edits"
model = "gpt-6-astra"

Set reviewer.verbose_output = true to show the full supervisor feedback in the terminal transcript.

Configuration reference

Nano

Key	Type	Default	Usage
nano.connection	string or string array	required	Existing connection name, or equivalent connections to rotate between.
nano.model	string	required	Model used for automatic naming.
nano.thinking_level	string	model default, otherwise medium	Reasoning effort supported by the selected model.
nano.model_verbosity	string	provider default	low, medium, or high.
nano.model_context_window	int	model context window	Required if Kent cannot determine the window. Minimum 2500.
nano.timeout_seconds	int	120	Inference timeout, including retries, starting when capacity is available. Must be positive.
nano.concurrency	int	5	Simultaneous nano calls across workspaces. Set only in global configuration. Must be positive.
nano.features.session_naming	bool	true	Automatic naming when nano is configured.
nano.model_capabilities.supports_reasoning_effort	bool	model capability	Override reasoning-effort support for a custom model.
nano.model_capabilities.supports_vision_inputs	bool	model capability	Override image and PDF input support for a custom model.

Supervisor

Supervisor settings use the [reviewer] table. Omitted model controls inherit the corresponding coding-agent settings.

Key	Type	Default	Environment variable	Usage
reviewer.connection	string	session’s selected connection		One existing connection name.
reviewer.frequency	string	edits	KENT_REVIEWER_FREQUENCY	off, all, or edits.
reviewer.model	string	inherits model	KENT_REVIEWER_MODEL	Model used for review.
reviewer.thinking_level	string	inherits thinking_level	KENT_REVIEWER_THINKING_LEVEL	Reasoning effort supported by the selected model.
reviewer.model_verbosity	string	inherits model_verbosity	KENT_REVIEWER_MODEL_VERBOSITY	"", low, medium, or high.
reviewer.model_context_window	int	inherits model_context_window	KENT_REVIEWER_MODEL_CONTEXT_WINDOW	Explicit context-window override. Minimum 40000.
reviewer.system_prompt_file	optional string	inherits system_prompt_file		Custom prompt path relative to the configuration file that supplies it. Empty paths are invalid.
reviewer.timeout_seconds	int	120	KENT_REVIEWER_TIMEOUT_SECONDS	HTTP timeout. Must be positive.
reviewer.verbose_output	bool	false	KENT_REVIEWER_VERBOSE_OUTPUT	Show full supervisor feedback in the terminal transcript.
reviewer.model_capabilities.supports_reasoning_effort	bool	inherits main model capability	KENT_REVIEWER_MODEL_CAPABILITIES_SUPPORTS_REASONING_EFFORT	Override reasoning-effort support for a custom model.
reviewer.model_capabilities.supports_vision_inputs	bool	inherits main model capability	KENT_REVIEWER_MODEL_CAPABILITIES_SUPPORTS_VISION_INPUTS	Override image and PDF input support for a custom model.
