Agent Atlas / Coding agents

mistralai/mistral-vibe

A terminal coding agent whose ACP compatibility, release checks, packaging, and contributor boundaries make interoperability and maturity the strongest teaching surfaces.

Teaching mechanism

Protocol compatibility is tested as a release contract

ACP support is tied to release evidence so compatibility is more than a capability claim in documentation.

Evidence limitPassing project-owned protocol tests does not prove compatibility with every client or production workflow.

System Map

Eight inspection boundaries
Model boundary

The CLI is oriented around Mistral's model path while exposing an agent interface to clients.

Context and memory

Repository and session context are assembled for terminal coding work.

Tools and execution

Coding tools act through the CLI runtime and can be surfaced through ACP.

Permissions and isolation

The inspected evidence emphasizes compatibility and release boundaries; complete host enforcement remains an inspection question.

Sessions and recovery

Protocol and release behavior provide the clearest public continuity contract.

Delegation

Multi-agent delegation is not the strongest currently reported mechanism.

Human control

Terminal and ACP client surfaces mediate operator interaction.

Evidence surface

Compatibility tests, releases, packaging, and contributor-visible changes provide the public receipts.

 Mistral Vibe Turns Release Claims Into Trust Boundaries

June 18, 2026 — The v2.16 release line says workspace trust, resume speed, diff rendering, SSE parsing, and backend reasoning behavior are no longer only UX claims; several now have code and tests behind them. mistralai/mistral-vibe

 Mistral Vibe's Contributor Door Is Half Open

June 13, 2026 — Mistral Vibe looks mature in release machinery and public feedback channels, but its own contributor guide keeps code contributions outside the main door for now. mistralai/mistral-vibe

Open Questions

  • Which compatibility claims remain stable across independent ACP clients and releases?

Evidence state describes what this Atlas profile can support today. It is not a product score and it is not evidence that uninspected capabilities are absent.
