Overview ¶

Package harness defines the contract between the runtime and external coding harnesses (Claude Code, Codex, ...) that agents configured with `harness:` delegate to. It carries no driver: pkg/codingharness implements it, and the runtime only links a driver once one is registered with runtime.RegisterHarness.

Types ¶

type Event ¶

type Event struct {
	Type       EventType
	Text       string
	Result     string
	SessionID  string
	Usage      *Usage
	ToolID     string
	ToolName   string
	ToolArgs   string
	ToolOutput string
	ToolError  bool
	Reasoning  string
}

Event is one streamed event from an external coding harness.

type EventType ¶

type EventType string

EventType identifies an Event.

const (
	EventText          EventType = "text"
	EventResult        EventType = "result"
	EventToolCallStart EventType = "tool_call_start"
	EventToolCallDelta EventType = "tool_call_delta"
	EventToolCall      EventType = "tool_call"
	EventToolResult    EventType = "tool_result"
	EventReasoning     EventType = "reasoning"
	EventSessionID     EventType = "session_id"
)

type Factory ¶

type Factory func(cfg *latest.HarnessConfig) (Provider, error)

Factory builds the Provider for a harness configuration.

type Provider ¶

type Provider interface {
	Name() string
	Run(ctx context.Context, prompt string, handle func(Event)) error
	Resume(ctx context.Context, sessionID, prompt string, handle func(Event)) error
}

Provider drives one external coding harness for an agent.

type Usage ¶

type Usage struct {
	InputTokens              int
	OutputTokens             int
	CacheReadInputTokens     int
	CacheCreationInputTokens int
	TotalCostUSD             float64
}

Usage is the token and cost report a harness emits with its result.
