# ruvllm_chat_format

Format chat messages using a template (llama3, mistral, chatml, phi, gemma, or auto-detect). Use when sending every prompt to the Anthropic API is wrong because you need local inference — air-gapped environments, MicroLoRA-fine-tuned per-task adapters, or sub-cent per-call cost. For general Claude work native Task is the right call.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "ruvllm_chat_format",
    "arguments": {}
  }
}
```

## Why ruvllm_chat_format is rated High

This tool formats prompts and triggers local inference execution (not just data transformation), routing prompts to local LLM backends. It executes inference operations whose effects depend on the template and prompt arguments. While it could be argued as a Write or Read operation, the invocation of local inference pipelines (MicroLoRA adapters, local model execution) makes Execute the most accurate category.

From the tool's own definition: "Format chat messages using a template (llama3, mistral, chatml, phi, gemma, or auto-detect)... you need local inference — air-gapped environments, MicroLoRA-fine-tuned per-task adapters"

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents invoke ruvllm_chat_format to trigger actions in Claude Flow. 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.
