# neuron_build_persona_from_text

Distill a reusable voice from raw text — no Collection or browser extension needed. Feed it pasted posts, a chat/dialogue transcript, WhatsApp-export text, or your own well-crafted writing sample, and it reverse-engineers a voiceProfile (tone, diction, cadence, emoji/formatting habits, themes, dos/donts) + exemplars. Provide text (auto-split into samples) and/or samples (already-split). Runs an LLM call (a few seconds).

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `name` | string | no | Persona name. Defaults to '<author> voice' or 'Custom voice'. |
| `text` | string | no | A raw blob to distill: posts, a dialogue, a chat transcript, or a writing sample. Auto-split into samples. |
| `samples` | array | no | Pre-split writing samples (alternative or addition to `text`). |
| `speaker` | string | no | If `text` is a chat transcript, keep only this speaker's lines (name match) — so a group chat yields one person's voice. |
| `platform` | string | no | Optional metadata tag for the samples (e.g. 'whatsapp', 'x'). |
| `authorLabel` | string | no | Who the voice belongs to, for a more grounded analysis. |
| `description` | string | no |  |

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "neuron_build_persona_from_text",

## Why neuron_build_persona_from_text is rated High

neuron_build_persona_from_text triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

## Use case

AI agents invoke neuron_build_persona_from_text to trigger actions in Neuron. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Neuron:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "neuron_build_persona_from_text": {
      "limits": [
        {
          "counter": "neuron_build_persona_from_text_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
