# WhisperGate Implementation Notes

## Decision path

WhisperGate evaluates in strict order:

1. channel check (discord-only)
2. bypass sender check
3. message ending symbol check
4. fallback to no-reply model override

## Why before_model_resolve

- deterministic
- no LLM dependency
- low overhead
- uses built-in override path (`providerOverride` + `modelOverride`)

## Known limitation

This does not fully skip OpenClaw prompt assembly. It reduces provider-side LLM usage by routing no-reply turns to a deterministic API.
