Mistral Vibe is a command-line coding assistant that lets users converse with a codebase and use natural language to explore or change projects. Developers use it for file editing, code searching, version-control tasks, and shell commands through Mistral’s models. Its catalogue add-ons provide skills and instructions for customizing the assistant’s workflows.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00052 | $0.00478 |
| Opus 5 | $0.00026 | $0.00239 |
| Sonnet 5 | $0.00010 | $0.00096 |
| Haiku 4.5 | $0.00005 | $0.00048 |
Grade A, and why
vibe-textual-ui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Vibe Textual UI
Conventions for building and styling Textual TUI widgets in Vibe. Apply when working in vibe/cli/, creating or modifying widgets, or writing TCSS.
Widgets
- For selectable lists, use
NavigableOptionListfromvibe/cli/textual_ui/widgets/navigable_option_list.pyinstead of Textual'sOptionList. It addsj/kcursor navigation on top of the arrow keys; the bareOptionListonly handles arrows. - Keep feature-specific Textual state and helper functions with the feature's widget package.
app.pyshould orchestrate mounting and message handling, not accumulate feature-local state models, defaulting helpers, or import factories. - Render tool headers as an explicit verb plus message in every state: progressive wording while a call is running, then a settled verb once any result arrives, including a failure. Preserve result metadata such as
(truncated)or(scratchpad)immediately after the message and keep error details in the expandable result body.
TCSS
- When a rule sets
color: $text-muted;, pair it with a nested&:ansi { text-style: dim; }so the muted intent survives under ANSI themes. - Never use
ansi_*colors (e.g.ansi_red,ansi_bright_blue). Use Textual theme variables like$primary,$foreground,$surface,$error, etc. — see https://textual.textualize.io/guide/design/. ANSI themes are derived from these variables automatically. - Keep truncation and overflow behavior declarative in TCSS. Do not add resize handlers or explicit widget-width calculations solely to force an ellipsis; accept clipping or overflow when Textual cannot express the layout reliably.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
