/** * ClaudeDriver — `ProviderDriver` for the Claude Agent SDK runtime. * * Mirrors `CodexDriver`: a plain value whose `create()` returns one * `ProviderInstance` bundling `snapshot` / `adapter` / `textGeneration` * closures captured over the per-instance `ClaudeSettings`. * * Unlike Codex, the Claude snapshot probe may invoke a secondary probe * (`probeClaudeCapabilities`) to read Anthropic account + slash-command * metadata. That probe is per-instance and keyed by binary + resolved HOME so * two concurrent Claude instances don't cross-contaminate account metadata. * * @module provider/Drivers/ClaudeDriver */import { ClaudeSettings, ProviderDriverKind, type ServerProvider } from "@t3tools/contracts";import * as Cache from "effect/Cache";import * as Duration from "effect/Duration";import * as Crypto from "effect/Crypto";import * as Effect from "effect/Effect";import * as FileSystem from "effect/FileSystem";import * as Path from "effect/Path";import * as Schema from "effect/Schema";import { HttpClient } from "effect/unstable/http";import { ChildProcessSpawner } from "effect/unstable/process"; import { makeClaudeTextGeneration } from "../../textGeneration/ClaudeTextGeneration.ts";import { ServerConfig } from "../../config.ts";import { ServerSettingsService } from "../../serverSettings.ts";import { ProviderDriverError } from "../Errors.ts";import { makeClaudeAdapter } from "../Layers/ClaudeAdapter.ts";import {  checkClaudeProviderStatus,  makePendingClaudeProvider,  probeClaudeCapabilities,} from "../Layers/ClaudeProvider.ts";import { ProviderEventLoggers } from "../Layers/ProviderEventLoggers.ts";import { makeManagedServerProvider } from "../makeManagedServerProvider.ts";import {  defaultProviderContinuationIdentity,  type ProviderDriver,  type ProviderInstance,} from "../ProviderDriver.ts";import type { ServerProviderDraft } from "../providerSnapshot.ts";import { mergeProviderInstanceEnvironment } from "../ProviderInstanceEnvironment.ts";import {  enrichProviderSnapshotWithVersionAdvisory,  makePackageManagedProviderMaintenanceResolver,  normalizeCommandPath,  resolveProviderMaintenanceCapabilitiesEffect,} from "../providerMaintenance.ts";import {  haveProviderSnapshotSettingsChanged,  makeProviderSnapshotSettingsSource,  type ProviderSnapshotSettings,} from "../providerUpdateSettings.ts";import { makeClaudeCapabilitiesCacheKey, makeClaudeContinuationGroupKey } from "./ClaudeHome.ts";const decodeClaudeSettings = Schema.decodeSync(ClaudeSettings); const DRIVER_KIND = ProviderDriverKind.make("claudeAgent");const SNAPSHOT_REFRESH_INTERVAL = Duration.minutes(5);const CAPABILITIES_PROBE_TTL = Duration.minutes(5); function isClaudeNativeCommandPath(commandPath: string): boolean {  const normalized = normalizeCommandPath(commandPath);  return (    normalized.endsWith("/.local/bin/claude") ||    normalized.endsWith("/.local/bin/claude.exe") ||    normalized.includes("/.local/share/claude/")  );} const UPDATE = makePackageManagedProviderMaintenanceResolver({  provider: DRIVER_KIND,  npmPackageName: "@anthropic-ai/claude-code",  homebrewFormula: "claude-code",  nativeUpdate: {    executable: "claude",    args: ["update"],    lockKey: "claude-native",    isCommandPath: isClaudeNativeCommandPath,  },}); export type ClaudeDriverEnv =  | ChildProcessSpawner.ChildProcessSpawner  | Crypto.Crypto  | FileSystem.FileSystem  | HttpClient.HttpClient  | Path.Path  | ProviderEventLoggers  | ServerConfig  | ServerSettingsService; const withInstanceIdentity =  (input: {    readonly instanceId: ProviderInstance["instanceId"];    readonly displayName: string | undefined;    readonly accentColor: string | undefined;    readonly continuationGroupKey: string;  }) =>  (snapshot: ServerProviderDraft): ServerProvider => ({    ...snapshot,    instanceId: input.instanceId,    driver: DRIVER_KIND,    ...(input.displayName ?
