Class: LittleGhost::Tools::WriteTodos

Inherits:
LittleGhost::Tool show all
Defined in:
lib/little_ghost/tools/write_todos.rb

Overview

WriteTodos lets an agent share a live plan with the application and the person following its work. Add it like any other tool:

class ResearchAgent < LittleGhost::Agent
tools LittleGhost::Tools::WriteTodos
end

Each execution replaces the full plan in RunContext state. Todo IDs remain stable across updates, statuses are pending, in_progress, or completed, and no more than one todo may be in progress. When no context is available, the tool retains fallback state on its instance.

def call(input)
  todos = input.fetch("todos")
  raise ToolError, "only one todo may be in progress" if todos.count { |todo| todo["status"] == "in_progress" } > 1

  ids = todos.map { |todo| todo.fetch("id") }
  raise ToolError, "todo IDs must be unique" unless ids.uniq.length == ids.length

  state = context ? (context.state["little_ghost.plan"] ||= empty_plan) : (@fallback_state ||= empty_plan)
  state.replace("plan_title" => input.fetch("plan_title"), "todos" => todos.map(&:dup))
  state.dup
end

#execute(input, context: nil) ⇒ Object

Trims user-facing titles before normal tool validation and execution.
