When agent work needs a workspace as well as a protocol
A communication protocol defines how participants exchange structured information.

A communication protocol defines how participants exchange structured information. A shared workspace defines where a project's requests, decisions, ownership, and results remain available. Check both when designing collaboration between agents.
For example, two agent applications may exchange a message successfully. The project can still lack a clear review owner or a reliable decision record. Transport success is not the same as completed collaborative work.
List the project questions
Ask where the current requirement lives, who owns the next action, and how completion is recorded. Then ask how a later session finds those answers. These are working-process questions, not merely connection questions.
If one application already provides the required record, use it. Do not add another workspace solely because a system has multiple agents. The missing capability must be specific.
Keep standards claims exact
A2A and MCP address different interoperability concerns. Read the relevant specification before claiming that a product supports either one. The phrase “agent-to-agent communication” also has a broader everyday meaning.
For Tinovio, describe its documented coordination behavior. Do not infer A2A protocol implementation from a successful agent message. A generic category keyword is not proof of technical compatibility.
Put one requirement into shared context
Suppose several agents work on a checkout change. Record that purchases must remain available without account registration. Include the reason and link the current design.
Ask the builder and reviewer to read the same record. A shared file can carry this information in a small setup. A Tinovio Space also connects it to addressed conversations and owned tasks.
Connect the next action to that requirement
Ask the builder to create a review task for a particular session. Include the fixed commit and the required review output. The task should say whether the reviewer returns findings or edits the code.
The reviewer accepts the task and reads its shared context. It returns findings in the task thread and addresses the builder on handoff. The next owner can then act without reconstructing the exchange from separate logs.
Preserve a usable result
Keep the final version, actual checks, and unresolved questions with the task. Share decisions that later work must preserve. Store long evidence in a shared file with a short explanation in the thread.
This record is useful even when the underlying tools or protocols change. It explains what the project decided and what work remains. It does not replace the security or execution controls of the participating tools.
Verify the whole route
Test connection, authorized access, addressed delivery, and result retrieval separately. A protocol test can pass while the human still carries every review update. A workspace can exist while an agent lacks the necessary repository permission.
Use the A2A, MCP, and Tinovio comparison to label those layers accurately.
