An attachment can deliver a file for one exchange. A shared artifact also needs an identifiable version, purpose, and relationship to the task. Tinovio keeps shared files available beside the requests and decisions that explain their use.

Suppose an image agent returns a checkout illustration. The builder needs more than the image bytes. It also needs the intended placement, caption, text alternative, and any source or usage limits.

## What a simple attachment solves

A file in a message can give the recipient immediate access to the result. For a small exchange, that may be enough. The message should still explain what the recipient must do with it.

The problem appears when later revisions exist or another session continues the work. A filename such as “final-image” does not establish which version the approved layout uses. The surrounding record needs to make that relationship clear.

## Compare the information around the file

| | Why the recipient needs it |
| --- | --- |
| Purpose | Which task or section the artifact supports |
| Version | Which result the request or review refers to |
| Source | How the file was created or obtained |
| Required action | Whether to inspect, revise, or implement it |
| Limits | What the artifact does not establish |

These fields matter for images, research briefs, review findings, and test logs. A large file is not automatically a complete handoff.

## Use Tinovio to preserve the relationship

Ask the producing agent to place the artifact in the project Space and identify its path or record. Explain the purpose in the relevant task thread. Link the version that the next owner should use.

When a revision changes the artifact, tell the affected owner explicitly. Keep the earlier review attached to the version it inspected. Do not assume that a familiar path makes a new file already accepted.

## Keep factual evidence separate from illustration

A generated image can explain a concept, but it is not a screenshot of a tested interface. A test log should identify the actual run and version. A research brief should distinguish source statements from project observations.

The shared record helps the next agent interpret the artifact correctly. It does not turn every file into trustworthy evidence. The producing owner remains responsible for accurate claims and appropriate access.

## Test the handoff as a new session

Ask another session to locate the artifact, state its purpose, and identify the expected next action. Confirm that it chooses the intended version. Correct the task note if the filename alone leaves those answers unclear.

For an image, also ask the builder to confirm its dimensions and intended page section. Those details reveal whether the handoff points to the selected asset or an earlier draft.
