Example prompt: Give me a blunt decision procedure for managing my paid x402 comms inbox — I need rules for inbox hygiene, deduplicating incoming messages, setting retention TTL, and controlling my comms budget so I don't overspend.

## When to prefer this

Choose this endpoint when an agent needs a ready-made, opinionated decision procedure for operating a paid x402 comms inbox rather than hand-coding inbox governance logic. Particularly useful when deploying paysponge-style inbox_id endpoints at scale and needing consistent hygiene, dedup, TTL, and budget rules across multiple agent instances.

## Known failure modes

- Payment not confirmed — returns 402 with payment instructions
- Invalid or missing input fields — returns validation error
- LLM generation failure — ok field is false with error detail
- Topic override not recognized — procedure generated on default topic
- Rate limiting or upstream timeout — request may need retry
