Mistral Vibe: Subagent Conversation Visibility From the Parent Session
Mistral VibeMistral Vibe's v2.25.5 release made subagent conversations readable directly from the owning parent session, so developers no longer have to hunt for a separate view to see what a subagent actually did. It also added configurable live subagent status alongside a read-only transcript switcher, letting a developer flip between watching a subagent run live and reviewing its full transcript from the interactive prompt. Together the two changes make delegated subagent work materially more transparent.
Key Takeaways
- Mistral Vibe now makes a subagent's full conversation history readable directly from the parent session that spawned it.
- A new configurable live status indicator lets developers watch a subagent's progress as it happens.
- A read-only transcript switcher in the interactive prompt lets developers review a subagent's full output without leaving the main session.
- The release shipped alongside related subagent bug fixes, including a crash when the subagent list updates and an Escape key that now reliably exits a subagent transcript.
- These changes target one of Mistral Vibe's core delegation mechanisms, making multi-agent workflows easier to audit.
- No independent third-party coverage exists yet for this specific feature.
Seeing What a Subagent Did, From Where the Work Was Delegated
Mistral Vibe's v2.25.5 changelog lists two related Added items: "Subagent conversation history is readable through the owning parent session" and "Configurable live subagent status and read-only transcript switching from the interactive prompt." Read together, they describe a single improvement to how visible subagent work is to the developer who kicked it off.
History Readable From the Parent
Previously, reviewing what a subagent actually said or did required navigating to it separately. Now that history surfaces through the parent session that spawned it, keeping the full delegation chain, main conversation and every subagent it triggered, in one place a developer can inspect without losing their spot in the primary thread.
Live Status and Read-Only Transcripts
The second change adds a configurable live status indicator for a running subagent plus the ability to switch to a read-only transcript view directly from the interactive prompt. That means a developer can watch a subagent's progress as it happens, then drop into its transcript to review exactly what it did, all without leaving the main session flow.
Why It Matters
Subagents are one of Mistral Vibe's core mechanisms for delegating multi-step work, and this release also shipped several bug fixes in the same area (a visible subagent instruction line that used to disappear on long transcripts, a crash when the subagent list updates mid-navigation, and an Escape key that now reliably returns from a subagent transcript). Combined, v2.25.5 is a meaningful transparency pass specifically on the subagent experience.
