Provider choice is an engineering constraint
Model capability, price, context length, availability, privacy requirements, and account policy change over time. A coding workflow that only works with one provider turns each of those changes into a migration.
A provider-agnostic agent separates provider configuration from agent behavior. The tools, workspace context, permissions, and session model stay stable while the active provider profile can change.
Use profiles instead of hardcoded assumptions
A profile describes the endpoint, model, credential reference, and context setting that make sense for a task. It can point to a local server or a supported cloud account. Credentials should be stored in client-managed secure storage rather than committed with a repository.
- Use a local profile for private or offline work.
- Use a cloud profile when a task needs stronger reasoning or capacity.
- Keep a fallback profile for provider outages or limits.
- Name profiles by purpose, not by a temporary model trend.
Flexibility needs an honest connection test
Provider support is only real when a profile can test its endpoint, authenticate, list or select a usable model, and report errors clearly. A 401 authentication failure, a network failure, and a rate limit are different conditions that should not be hidden behind one message.
Truss keeps provider selection within the same runtime so a change in model provider does not require a different client workflow or tool policy.

FAQ
Questions developers ask before switching.
What does provider-agnostic mean for an AI agent?
It means the agent is designed to work with multiple compatible model providers while keeping its context, tools, permissions, and client workflow independent from any one vendor.
Does provider-agnostic mean every model works equally well?
No. Models differ in tool use, context, reliability, and price. Provider flexibility lets you choose deliberately without replacing the entire workflow.
