# Personalize your agent

Personalization has several separate controls. Your name helps Nock address you, voice settings change spoken delivery, and named-agent instructions shape a particular agent's behavior. Changing one does not automatically change the others.

## Set your name

Open **Settings → Agent → About you**. Edit **First name** and **Last name**, then leave the field so the change saves. The first-run introduction may already have filled these values. Check the saved field if the greeting uses the wrong name.

The Home greeting uses your first name. Your name can also accompany agent turns as context, so choose the information you are comfortable sharing with the model. These fields are not a complete memory editor, and changing them does not erase previous conversations.

Words you want dictated accurately belong in the [Dictionary](/nock/dictionary). Automatic text substitutions belong in [Replacements](/nock/replacements). Adding a project name to About you will not train the transcription system to spell it correctly.

## Tune spoken delivery

Use the Agent voice controls to select an available voice and speed. Try a short question and listen to a full response before making another adjustment. A slower voice can improve clarity without requiring the agent to produce a longer answer.

For a custom character, open **Edit agent** and select its own voice. The automatic option assigns a consistent voice. A named agent's voice and Nock's main voice are separate settings, so confirm which conversation is selected when comparing them.

## Write useful instructions

In a named agent, use **Character** for its role, **Personality** for its tone, and **Instructions** for observable working rules. For example: “Give me the recommendation first, then two reasons. Ask before changing the intended audience.”

Test that instruction on a small task and revise it if necessary. Avoid making the same rule conflict across several fields. Keep private credentials out of personality text and `SOUL.md`; those instructions travel with messages and are not a secret-storage mechanism.

An agent description cannot add a missing connection, grant a permission, or enable a restricted account feature. Use the corresponding Settings section when you need to change access. See [Named agents](/nock/named-agents).

## Ask Nock to change a preference

**Settings → Agent → Let the agent change settings** lets you request supported preference changes conversationally, such as changing voice speed or weather units. Each change asks for approval. Read the proposed value before accepting it and confirm the setting afterward.

The tool is limited to supported preferences. It does not change keys, operating-system permissions, keyboard shortcuts, or the rules governing what actions the agent may take. When a change is outside that scope, use the Settings control Nock identifies. Turning the preference tool off still allows Nock to explain where a setting is.

See [Voice settings](/nock/voice-settings), [Task approvals](/nock/task-approvals), and [Privacy](/nock/privacy) for related controls.
