Configuration and routing

Locations

Item	Location
Global configuration	${XDG_CONFIG_HOME:-$HOME/.config}/ribbit/config.yaml on Unix; the same XDG override or the user's home .config/ribbit/config.yaml on Windows
Project inference	.ribbit.yaml in the working project
Project named commands	commands/*.yaml or commands/*.yml
Global named commands	commands/ beside the global config file
Installed extensions	${XDG_DATA_HOME:-$HOME/.local/share}/ribbit/extensions, using the user's home on Windows

Global config contains schemaVersion: 1, providers, profiles, default, and routes. A project config uses apiVersion: ribbit/v1 and an optional inference object.

The project-root .env file is loaded at CLI startup. Existing process environment values take precedence; a missing file is allowed. Credentials are referenced by environment-variable name, never stored as literal provider keys.

Provider fields

Field	Meaning
type	ollama or openai-compatible
baseUrl	HTTP(S) endpoint without embedded credentials, query, or fragment
apiKeyEnv	Optional environment-variable name for authentication
defaultModel	Optional model ID used with a provider-only override
models	Optional allowlist of model IDs
contextTokens	Optional declared context size
capabilities	Declared subset of text, stream, object, temperature, maxOutputTokens, reasoning

Capabilities must match the endpoint. A resolved route requiring an undeclared capability fails before inference.

Inference fields

profile, provider, model, temperature, maxOutputTokens, timeout, and reasoning are the supported inference keys. A profile names a complete provider/model route with optional settings. reasoning is off or on.

For an example global default:

default:
  profile: local-small

This fragment belongs in an existing valid global config and requires that profile to exist. Use model setup to create providers and profiles.

Precedence

Routes merge from weaker to stronger layers:

1. Global default.
2. Project inference.
3. Saved flow inference.
4. Flow invocation defaults.
5. Per-command route.
6. Named definition inference.
7. Step inference.
8. Command/segment CLI overrides.

--force-profile replaces managed routes across a flow after these layers. It applies only to flows. A provider override selects that provider's default model unless the layer also supplies a model; it does not silently retain another provider's model.

Inspect a route with ribbit route inspect COMMAND --profile NAME --json. No automatic fallback occurs when a route fails.

Reasoning controls

Ollama uses its native think field. The compatible adapter sends chat_template_kwargs.enable_thinking only when the provider declares reasoning; support depends on the server and model template. Structured managed calls default reasoning off when control is available. Free-text calls keep the model's default unless configured.

A model may spend its output allowance on internal reasoning before producing a visible answer. Configure an appropriate maxOutputTokens in the profile; it is distinct from the invocation's aggregate --max-tokens budget.
