v0.4.0 — protocol surfaces v1

Your AI agent gets more ways to help you: packaged workflow prompts you can invoke from your client, maintained guidance served as resources, clearer step-by-step error messages written to be relayed to you, and tool metadata that lets clients run read-only calls without friction. Same privacy rules and opt-outs as always.

Live progress — searches across the five paper indexes now stream per-source progress when your client supports it. And if Semantic Scholar is rate-limited, supporting clients can ask you for a free API key right in the conversation (used for the session only, never stored).
