omni retrieve

Prints the content a marker archived.

omni retrieve <handle>

The handle is the 16 characters inside a marker:

[OMNI: 406 lines omitted, omni retrieve 0000000000000000 for full output]
[OMNI: 40 lines already shown, omni retrieve 0000000000000000]

It returns the original bytes. Not a summary, not a re-run of your command, and not an approximation.

Works on every host, in any session, whether or not MCP is wired. Agents with the MCP server registered call omni_retrieve instead and never have to ask you.

What can go wrong

The handle does not resolve. The archive is a rolling 30 day window, so content older than that is gone. Verbatim execution traces are pruned sooner still, at seven days.

A handle that fails to resolve inside the window is a serious bug rather than an inconvenience, because a marker promising retrievable content is the one thing this mechanism cannot get wrong. Report it.

You typed the marker text, not the handle. Only the hex, no brackets, no prefix.

Why it can promise this

A run is archived before its marker is written, and a failed archive leaves the run verbatim rather than producing a marker. So a handle you can see is a handle whose content exists. That ordering was a fix, not the original design: an earlier version returned a key even when the write had failed.
