Add an immediate-value first-conversation recipe

Goal

Provide a reusable first-conversation pattern that demonstrates capability through grounded SaaS value instead of a generic chatbot greeting or setup questionnaire.

Scope

• New, returning, unlinked, zero-resource, one-resource, and multi-resource examples.
• Useful first response from authenticated context without asking for known data again.
• Natural project/account selection and interruption handling.
• Concise disclosure, help, feedback, and web handoff.
• Privacy-safe activation funnel.

Acceptance criteria

• Example adapter fixture and Eve evals cover each state.
• Replies contain no raw Markdown, internal implementation terms, false progress language, or unnecessary confirmation loops.
• A reader can adapt the recipe without copying product-specific business logic.
• Documentation defines first-value and drop-off events without message content.
