Overview ¶
Package configdriven implements a generic AI provider whose behaviour is driven by an [[ai_provider]] block in a package's ailang.toml manifest. See design_docs/planned/v0_15_0/m-ai-provider-config.md.

Types ¶
type HeaderPair ¶
HeaderPair is one (name, value) entry for the StreamSSEPost headers list. Mirrors the AILANG-side `{name, value}` record shape that StreamSSEPost expects in its config arg.
type Option ¶
type Option func(*Provider)
Option configures a Provider at construction time.
func WithHTTPClient ¶
WithHTTPClient overrides the default HTTP client. Used by tests with httptest.Server-backed clients.
type Provider ¶
type Provider struct {
// contains filtered or unexported fields
}
Provider is the generic ai.Provider implementation driven by an [[ai_provider]] block in a package's ailang.toml manifest.
One Provider instance corresponds to one [[ai_provider]] block. The runtime registers many of these — one per declared block across all installed packages — alongside the hardcoded built-in providers (openai, anthropic, gemini, ollama, openrouter).
Per the [[ai_provider]] design (see design_docs/planned/v0_15_0/m-ai-provider-config.md):
- AIRoutingPolicy on the request is rejected (D11; non-OpenRouter providers must reject non-zero policies — silent routing fallback is forbidden)
- Image generation requests are rejected unless capabilities.vision is true
- Capability-mismatched requests fail fast with CapabilityNotSupported
- Trace spans match the structure of built-in provider spans (so replay/observability tooling treats config-driven and built-in providers identically)
func New ¶
func New(spec *pkg.AIProviderSpec, opts ...Option) *Provider
New creates a Provider for the given [[ai_provider]] spec. The spec is retained by reference; callers must not mutate it after construction.
func (*Provider) Name ¶
Name implements ai.Provider — returns the provider name from the config (e.g. "vllm" for an [[ai_provider]] with name = "vllm").
func (*Provider) Spec ¶
func (p *Provider) Spec() *pkg.AIProviderSpec
Spec returns the provider config that drives this Provider's behaviour. Consumed by the streaming dispatch layer (internal/effects/ai_streaming.go) which needs the streaming sub-block, request shape, and auth fields to construct an SSE-POST request. Returned by reference; callers must NOT mutate it.
type StreamRequest ¶
type StreamRequest struct {
URL string
Body string
Headers []HeaderPair
}
StreamRequest is the prepared input to effects.StreamSSEPost: the URL to POST to, the JSON body, and the resolved auth + content headers.
func BuildStreamRequest ¶
func BuildStreamRequest(spec *pkg.AIProviderSpec, model string, messagesJSON string) (*StreamRequest, *ai.ProviderError)
BuildStreamRequest prepares an SSE-POST request from an [[ai_provider]] spec plus a model + serialised messages. Resolves env-var references at call time so credentials don't leak into start-time globals. Returns an AI-shaped error on capability mismatch or auth failure so the caller can short-circuit without hitting the network.
Callers (effects/ai_streaming.go): do NOT bypass this — Stream-effect-only code paths break the AI cap (D1) and budget tracking (D11). All AI streaming dispatch goes through here so the budget/cap/span machinery applies uniformly.
