The `output` string of a5 * control tool is a placeholder — the engine replaces it with the real outcome (owner's answer, gate error…).6 */7import { z } from 'zod';8import type { ResultEnvelope } from '@aos/shared';9import { opt, toStrictJsonSchema } from './schema.js';10import type { Tool, ToolRunResult } from './types.js';1112export const CONTROL_TOOL_NAMES = ['ask_owner', 'propose_criteria', 'update_criteria', 'finish'] as const;13export type ControlToolName = (typeof CONTROL_TOOL_NAMES)[number];14export function isControlTool(name: string): name is ControlToolName {15 return (CONTROL_TOOL_NAMES as readonly string[]).includes(name);16}1718// ---- inputs ------------------------------------------------------------------------------------------------1920export const AskOwnerInput = z.object({21 question: z.string().min(1).max(4000).describe('The question, self-contained: the owner may read it days later on a phone without the conversation.'),22 options: opt(z.array(z.string().min(1).max(300)).max(8)).describe('Optional short answer choices (the owner can still answer freely). null when open-ended.'),23});24export type AskOwnerInput = z.infer<typeof AskOwnerInput>;2526export const ProposeCriteriaInput = z.object({27 criteria: z.array(z.string().min(1).max(1000)).min(1).max(12).describe('3 to 8 verifiable done criteria, each checkable by a command, a test or a file inspection.'),28 rationale: opt(z.string().max(2000)).describe('One or two sentences on why these criteria cover the objective. null if obvious.'),29});30export type ProposeCriteriaInput = z.infer<typeof ProposeCriteriaInput>;3132export const UpdateCriteriaInput = z.object({33 updates: z34 .array(35 z.object({36 id: z.string().min(1).max(100).describe('Criterion id exactly as listed in the mission (e.g. "c1").'),37 passes: z.boolean().describe('true once verified; false to retract a previous pass.'),38 evidence: z.string().max(2000).describe('What proves it: the command run and its result, the test name, the file and line.
