Source reference: [Proposal] New experimental repository: experimental-cpb-websocket # WebSocket Custom Protocol Binding for A2A - Proposal ## Abstract This proposal requests the creation of an `experimental-cpb-websocket` repository under the `a2aproject` GitHub organization to host the **WebSocket** custom protocol binding for A2A. The binding carries the **existing** A2A method inventory - the same operations, request/response shapes, and server-streaming semantics defined by the core specification and used by the JSON-RPC binding - over a single, long-lived [WebSocket](https://datatracker.ietf.org/doc/html/rfc6455) connection. It is layered: - **Transport:** WebSocket This is an imported issue report, not a local participant or a verified incident.

Source reference: Preventing tool poisoning: save signatures of possible tool calls One potential benefit of a centralized registry is that we could have `server.json` submitters list out all the possible tools their server may ever invoke, fingerprint them, and store those fingerpoints for MCP client consumption. A third party vendor could scan and approve these fingerprints as devoid of security risks, like tool poisoning attacks. MCP clients could then use the fingerprints to avoid tool poisoning attacks that get surfaced due to hidden dynamic tool calls or supply chain attacks.

Source reference: [Extension Proposal] AAE profile: verify an Agent Authorization Envelope before a skill runs. ### Is your feature request related to a problem? Please describe. A2A Β§7.5 leaves authorization to the server, and Β§7.6.4 says the meaning and scope of a credential obtained during `TASK_STATE_AUTH_REQUIRED` must be defined by the implementation, the issuer, or an extension. For agent-to-agent calls where the caller acts under a delegated mandate (what it may do, within which limits, until when), there is no extension that defines how such a mandate is presented, bound to the caller, checked against the requested skill, and how a refusal is reported. ### Describe the solution you'd like A This is an imported issue report, not a local participant or a verified incident.

Source reference: Clarify HTTP live-message routing when multiple exchanges share a task Section 3.1.12 of the 1.1 specs describes live messaging over HTTP: > To send further input, the client makes additional, short-lived calls to the same operation. Could we clarify how a client makes these additional calls and how the server distinguishes them from calls opening a new live exchange? For example: 1. A client calls `POST /message:live`, opening a streaming downlink. 2. The client calls `POST /message:live` again with another message for the same task. What tells the server that the second call should return a task acknowledgement rather than open another streaming response?

Source reference: [Feat]: Data labeling ### Is your feature request related to a problem? Please describe. There is no standard way for agents to label their responses (text and other artifacts) to indicate whether it contains data that needs to be kept private (e.g., PII, NTK, user data, etc) or may alter the agent's behavior (e.g., untrusted data which may lead to prompt injection). Google workspace API, for example, can return metadata about documents and an agent could use that to populate such fields. This sort of metadata is useful to enforce policies on data flow (including propagating that information in longer-lived agenti This is an imported issue report, not a local participant or a verified incident.
