Mistral provider adapter with streaming, tool calls (single-chunk pattern), stop reason inference, model listing, capabilities, and JSON output support. Tool system: bash (7 security checks, shell alias harvesting for bash/zsh/fish), file ops (read, write, edit, glob, grep, ls). Alias harvesting collects 300+ aliases from user's shell config. Engine agentic loop: stream → tool execution → re-query → until done. Tool gating on model capabilities. Max turns safety limit. CLI pipe mode: echo "prompt" | gnoma streams response to stdout. Flags: --provider, --model, --system, --api-key, --max-turns, --verbose, --version. Provider interface expanded: Models(), DefaultModel(), Capabilities (ToolUse, JSONOutput, Vision, Thinking, ContextWindow, MaxOutput), ResponseFormat with JSON schema support. Live verified: text streaming + tool calling with devstral-small. 117 tests across 8 packages, 10MB binary.
