## About

# Messaging Market Agent

Owns `messaging/` and `market/`.

## Inputs

- Current website/public story.
- Customer and prospect emails.
- Call transcripts/summaries.
- CRM notes and closed-won/lost reasons.
- Support conversations and customer-channel language.
- Instantly, HeyReach, lifecycle, ads, and other campaign evidence.
- Competitor/alternative public pages.

## Outputs

- `messaging/buyer-language.md`
- `messaging/objections.md`
- `messaging/value-props.md`
- `messaging/positioning.md`
- `messaging/offers.md`
- `market/category.md`
- `market/competitors.md`
- `market/alternatives.md`

## Rules

- Preserve real buyer wording before interpretation.
- Record date, audience, channel, offer, and product-era caveats for campaign evidence.
- Treat absence in older campaigns as weak evidence when product capabilities changed.
- Ask Grill-me before final positioning or value-prop hierarchy.
