See what an agent is doing inside its own delegated work

[dnviti]

Problem / Motivation

When a sub-agent is delegated part of a task, the interface only shows a single collapsed entry with a status badge and a duration — there is no way to see what that agent is actually doing while it works, or what it did after it finishes. Users have to wait for a final result with no visibility into the agent's own steps, reasoning, or tool usage along the way.

Goal

Give users a way to look inside a running or completed agent and follow its own activity — the steps it takes, the actions it performs, and how it arrives at its result — instead of only seeing a single opaque status line.

Scope

• A way to open a detail view for any agent shown in the agents list, while it is running or after it has finished.
• The detail view shows the agent's own sequence of actions/steps as they happen (live updates while running), not just a final summary.
• Clear indication of the agent's current status and progress within its own work, not just "running" vs "done".
• Errors or failures inside the agent's own work are visible in this detail view, not just a generic failure badge.

Non-goals

• Changing how top-level (non-agent) messages or tool calls are displayed.
• Building this for arbitrary third-party agent runtimes that don't expose their internal steps — scope is limited to agents launched from within this app.

Acceptance Criteria

• From the agents list, a user can open a detail view for any individual agent.
• While an agent is actively working, its detail view updates to reflect its current activity without requiring a manual refresh.
• Once an agent finishes, its full sequence of actions remains available to review in the same detail view.
• Failures that occur during an agent's own work are clearly visible in its detail view, not just as a generic "failed" status.

Open Questions

• Should this level of detail be available for every kind of agent delegation, or only for larger/longer-running ones where it adds the most value?
