Types

type AgentLoop 

type AgentLoop struct {
	Registry       *provider.Registry
	Session        *Session
	ToolRegistry   *tools.Registry
	Approval       *tools.ApprovalGate
	ContextManager *ContextManager
	WorkspaceRoot  string
}

func NewAgentLoop 

func NewAgentLoop(registry *provider.Registry, session *Session, toolReg *tools.Registry, approval *tools.ApprovalGate) *AgentLoop

func (*AgentLoop) Run 

func (a *AgentLoop) Run(ctx context.Context) error

type CommandContext added in v0.4.0 

type CommandContext struct {
	Session        *Session
	Registry       *provider.Registry
	ContextManager *ContextManager
	WorkspaceRoot  string
	AskApproval    func(prompt string) bool
}

CommandContext holds the environment and services needed to execute slash commands.

type CommandResult added in v0.4.0 

type CommandResult struct {
	Handled bool
	Output  string
	Error   error
	Exit    bool
}

CommandResult represents the outcome of executing a command.

func HandleCommand added in v0.4.0 

func HandleCommand(ctx context.Context, cmdCtx CommandContext, input string) CommandResult

HandleCommand processes slash commands (and exit/quit). Returns Handled=true if the input was a command, or Handled=false if it should be sent to the LLM.

type ContextManager 

type ContextManager struct {
	MaxTokens int
}

ContextManager manages message history size, truncation, and compaction.

func NewContextManager 

func NewContextManager(maxTokens int) *ContextManager

NewContextManager creates a ContextManager with the specified max tokens limit. If maxTokens <= 0, defaults to 8192.

func (*ContextManager) Compact added in v0.4.0 

func (cm *ContextManager) Compact(history []provider.Message, keepLastTurns int) []provider.Message

Compact summarizes or compresses the history by retaining the system prompt, a brief summary of omitted turns, and the most recent N turns.

func (*ContextManager) EstimateTokens 

func (cm *ContextManager) EstimateTokens(msg provider.Message) int

EstimateTokens calculates an approximate token count for a message.

func (*ContextManager) FormatContextStats added in v0.4.0 

func (cm *ContextManager) FormatContextStats(history []provider.Message) string

FormatContextStats returns a formatted status string of token usage.

func (*ContextManager) Truncate 

func (cm *ContextManager) Truncate(history []provider.Message) []provider.Message

Truncate enforces MaxTokens while preserving conversation structure: 1. Always preserves the system message (if present). 2. Truncates in whole conversation turns so tool-call / tool-result pairs are never separated. 3. Never leaves an orphaned "tool" message at the beginning of the context. 4. Always retains at least the latest user turn.

type PromptOptions added in v0.4.0 

type PromptOptions struct {
	ProjectContext string
	GlobalContext  string
	WorkspaceRoot  string
	OS             string
