mistralai/mistral-vibe v3.1.1

on GitHub

Added

• vibe-acp notifies the client when the administrator changes the organization's Vibe Code configuration.
• Vim Normal and Insert modes in the prompt input, enabled with the vim_keybindings config option
• The prompt of the conversation section at the top of the screen stays pinned while you scroll, and a click jumps back to it
• enable_sticky_prompt = false turns the pinned prompt off
• pre_agent hooks run before the model reads a user message: they can block it, rewrite its text, or add context for the model.
• notification hooks run in the background when Vibe needs your approval or an answer, or when a turn completes or fails.
• session_start hooks run when a session starts, resumes, is cleared or forked, and can add context for the model to the next message.
• session_end hooks run in the background when a session ends, with the reason (exit, clear or other).
• Built-in /vibe:import skill that finds your setup from other coding agents and imports instructions, skills, subagents, commands, hooks, MCP servers and permissions into Vibe
• vibe -p reports each denied tool call on stderr and in the export's warnings
• vibe -p says on stderr when the agent finishes without an answer
• Commands the agent runs get VIBE_SESSION=1 in their environment, so scripts can detect they run under Vibe
• On macOS and Linux, with nothing selected, Ctrl+Y pastes back the text last deleted with Ctrl+K, Ctrl+U, Ctrl+W or Alt+D.
• App servers offer a new agentWorktrees client capability: its sessions get the enter_worktree tool, and before editing the user's checkout the agent asks whether to work in a new git worktree or in place. A session can hold several worktrees; each is listed in artifacts/list and cleaned up when the session is archived.
• With the model catalog enabled, a model's old name (its catalog aliases) now works everywhere a model is named: [models.<old name>] settings apply to the model, and --model <old name> or the ACP model option picks it
• /pr lists the session's pull and merge requests with their number, title and state (green open, grey draft, purple merged, red closed).
• In /pr, c opens the first failing CI check and f drafts a prompt asking the agent to fix what blocks the PR.

Changed

• Session ids shown for vibe --resume now use the last 8 characters of the id; the first 8 still resume older sessions.
• Quitting Vibe waits up to 5 seconds for notification and session_end hooks still running.
• On macOS and Linux, what a bash command or a hook starts with & is stopped when it exits: long-running commands go through background processes.
• /branch now works while the agent is running, forking the conversation as it was before the current turn, and shows the command that resumes the copy in a panel instead of the conversation.
• Errors from pickers and keyboard actions (session resume, model, thinking, log level, agent switch, MCP browser, image paste, voice, external editor, queued-message edits) now show above the input until the next key instead of staying in the conversation.
• The startup Warnings box now goes away after your first message or when you resume another session.
• Markdown tables wider than the terminal size their columns to render as few lines as possible, keeping words whole where they can.
• --yolo / --auto-approve on a new session now starts the auto-approve agent instead of a hidden bypass on ask, accept-edits or smart-approve, so Shift+Tab can leave it; the session resumes on that agent.
• Hovering the model, the PR link or the context gauge now tints and bolds them instead of painting them blue
• The footer's copy-path icon now appears only when the working directory is shortened.
• Prompts sent by a scheduled loop now show only the loop's title, with its instructions and fired-at line folded until clicked or expanded with Ctrl+O, and scheduling a loop shows only its title.
• A model pick now saves active_model under the name the config file already uses for that model (during the catalog rollout), so older versions sharing the file still resolve it
• When the model catalog is turned on for your account, the model list no longer shows a second copy of a catalog model, and the catalog's recommended model is the default.
• With the model catalog enabled and listing at least one model, the built-in default model is not available anymore: the pickers show one row per catalog model, and a catalog alias can take the built-in's name (e.g. a pin on mistral-medium-3.5 runs the catalog's mistral-medium-latest when the catalog lists that alias)
• allowed_models patterns now also match a model's catalog aliases, so an allowlist written against a retired built-in's name (e.g. mistral-vibe-cli-*) keeps matching the catalog model that replaces it
• Pull requests and merge requests of a session are now tracked by default (with gh or glab); set enable_pr_monitoring = false (or VIBE_ENABLE_PR_MONITORING=false) to turn this off
• Sessions of one account and client now share one experiment evaluation per app server, kept on disk, so opening a session no longer waits on it after the first run
• The footer shortens a long working directory one word at a time instead of jumping to its last folder.
• An unreachable MCP server is retried after a growing delay instead of by every session that opens, and a server due a refresh is refreshed once for every session.
• When Mistral refuses your sign-in again right after renewing it, Vibe now asks you to update Vibe or sign in again.
• Plugin skills, knowledge and agents are named after the plugin as written (my-plugin:review) instead of its tool namespace (my_plugin:review)
• Custom agents whose enabled_skills or disabled_skills name plugin skills by the tool namespace (my_plugin:*) need the plugin name instead (my-plugin:*)
• Clicking the footer's PR/MR link opens /pr and refreshes the statuses; clicking it again closes the list.
• The footer's PR/MR status names its cause (CI failing, changes requested, conflicts, CI running, review required), prefers the open PR over merged or closed ones, and reads bold until a new status has been seen.
• A refused rewind or fork now says what is still running, such as a background process or a subagent, and a refused rewind shows as a notice instead of a conversation row.
• In vibe-acp and headless runs, the agent no longer assumes its replies are shown in a terminal, and writes markdown that reads well in any client

Fixed

• Rust CLI: moving the mouse outside the terminal window no longer highlights the subagent row or footer item on the same line.
• The update prompt no longer reports a failed update when uv shows a download progress bar
• Links in the transcript and onboarding open with your terminal's own link click (such as Cmd+click), including over SSH.
• New files follow the line endings the repository's .gitattributes sets for them.
• The agent no longer stops editing a file because of Windows (CRLF) line endings.
• Queued messages run again after a turn fails on a storage error such as a full disk, once the disk has space.
• On Windows, the agent writes paths in PowerShell and Git Bash commands so backslashes no longer break them.
• Update checks work again with uv older than 0.10.10 instead of silently finding no new version
• A subagent's scheduled prompts now run in that subagent, and it can only list, cancel or clear its own, not the main session's.
• Reading a log full of control characters no longer floods the context window.
• A model whose auto-compaction threshold does not fit its context window now compacts at the closest threshold that fits, with a warning, instead of failing to start or to be picked
• Release notes no longer stay pinned below the conversation when the first prompt is sent at startup
• The input caret no longer disappears when your text reaches the right edge of the input.
• The context gauge keeps its unused part visible while hovered
• vibe -p --agent with an unknown or unavailable agent exits as a usage error (exit 1), and --agent plan says it was removed and names its replacement
• A default_agent in the config that cannot start is reported as a configuration error
• Mistral Large 4's thinking picker offers Low, Medium and High, the levels the API now takes, instead of Low, High and Max when its config lists no levels.
• On Windows, multi-line pastes in terminals that send LF line breaks, such as WezTerm, no longer submit a prompt at each line.
• A provider error echoing a large payload, such as a rejected image, no longer freezes the terminal UI.
• /clear now starts a conversation with no scheduled prompts; the cleared session keeps its own and runs them again when resumed.
• Picking a model or thinking level no longer shows a false "A turn is already running" error when you send a prompt right after.
• Connectors no longer all fail to load with "Connector bootstrap cache projection exceeds 2 MiB" on accounts with many connectors
• Fixed sessions that failed and could not be resumed after a script passed a tool something other than an object
• A resumed session uses the model and agent it last ran, instead of the current default.
• Sessions start again when a cache file in ~/.vibe contains invalid UTF-8 bytes.
• Commands run by Vibe no longer inherit GIT_PYTHON_GIT_EXECUTABLE, which broke import git in containers or remote jobs where Git lives elsewhere.
• Subagent spawns no longer fail as often because the model left out the task message.
• /compact no longer fails and blocks the session when a warning arrives during the compaction, such as a cut-off summary.
• Skills whose frontmatter values contain an unquoted colon now load instead of failing with an invalid YAML error
• vibe doing nothing on Windows machines without the Visual C++ Redistributable
• On dedicated deployments where only api_base is set, the admin-managed config and account links now use the deployment's chat URL instead of chat.mistral.ai
• Ctrl+Z on Linux no longer occasionally hangs without returning to the shell prompt.
• File autocomplete no longer rescans the whole folder when dependencies change ignore files, such as during npm install.
• Clicking the footer's context gauge again now closes /context.
• Clicking a footer link or the context gauge no longer starts a text selection.
• A turn interrupted right after it starts no longer stays shown as running.
• Interrupting or messaging a subagent no longer fails when the parent turn ends while the request is still running.
• A managed worktree whose checkout lost its .git is reported once in the log instead of every few seconds.
• Plugins with an unknown top-level plugin.json field now load, with a warning, instead of being skipped.
• Plugins whose ai.mistral.vibe extension has an unknown key or declares volumes now keep their hooks, knowledge, and agents.
• A pull request the agent opens after writing its description in a heredoc that contains an apostrophe now shows up on the session.
• The same pull request no longer shows twice in the footer's PR list.
• A command that creates several PRs/MRs now records all of them.
• Rewinding no longer fails after a background process finishes between turns.

Removed

• The /teleport command is gone from vibe-acp.
• The /remote-project command is gone.
• The /teleport command, the & prompt prefix and the --teleport flag are gone; passing --teleport is now an error.
• The experimental_enable_pr_monitoring and experimental_enable_pr_discovery settings and the VIBE_EXPERIMENTAL_ENABLE_PR_MONITORING variable are gone and now ignored; use enable_pr_monitoring
• A skill named pr can no longer be run as /pr, which now opens the built-in PR list.
