@nestm/provider-status

Provider-neutral availability monitoring for NestJS 12. The package combines public provider status feeds with local request observations, exposes immutable snapshots through a service and RxJS observables, and includes optional dashboard HTTP/SSE and AI SDK integrations.

Built-in OpenAI API and Claude API status sources
Generic support for Statuspage-compatible summary or split endpoints
Application-owned custom and passive providers
Central polling with timeouts, jitter, stale detection, and non-overlapping checks
Local success, failure, error-rate, consecutive-failure, and optional latency observations
Immutable snapshots, provider-specific streams, and warning streams
Adapter-neutral JSON and Server-Sent Events endpoints for dashboards
AI SDK language-model middleware that records outcomes without blocking calls by default
Framework-neutral core and deterministic, network-free testing utilities

Provider status is advisory unless the application explicitly opts into availability enforcement. The package does not automatically retry, reroute, select fallback models, or fail NestJS readiness.

This package targets stable NestJS 12 and is itself published on the alpha dist-tag.

Architecture and entry points

Each entry point has a narrow dependency boundary:

Entry point	Purpose
`@nestm/provider-status`	NestJS module, lifecycle-aware service, shared types, and utilities
`@nestm/provider-status/core`	Framework-neutral monitor, contracts, status helpers, and errors
`@nestm/provider-status/statuspage`	Generic Statuspage source plus OpenAI and Anthropic presets
`@nestm/provider-status/http`	Adapter-neutral Nest controller for dashboard JSON and SSE
`@nestm/provider-status/ai-sdk`	Optional AI SDK 7 model middleware, resolver, and injectable service
`@nestm/provider-status/testing`	In-memory provider and polling-disabled Nest testing module

The root entry point does not load ai, Express, Fastify, or a concrete provider SDK. The core entry point has no NestJS imports. Applications own credentials, custom status endpoints, provider clients, authentication, routing policy, and persistent telemetry.

Requirements

Node.js 22.12 or newer
NestJS ^12.0.0
RxJS ^7.8
ESM

Installation

pnpm add @nestm/provider-status@alpha \
	@nestjs/common@12.0.1 @nestjs/core@12.0.1 \
	reflect-metadata rxjs

Install AI SDK 7 only when using the optional AI integration:

pnpm add ai

The HTTP entry point uses Nest's platform-neutral controller APIs. It does not add Express or Fastify as a peer dependency; use whichever Nest HTTP adapter the application already owns.

Quick start

Register the built-in API sources once in the application root:

import { Module } from "@nestjs/common";
import { ProviderStatusModule } from "@nestm/provider-status";
import {
	createAnthropicStatusProvider,
	createOpenAIStatusProvider,
} from "@nestm/provider-status/statuspage";

@Module({
	imports: [
		ProviderStatusModule.forRoot({
			providers: [createOpenAIStatusProvider(), createAnthropicStatusProvider()],
			polling: {
				intervalMs: 60_000,
				timeoutMs: 5_000,
				staleAfterMs: 5 * 60_000,
				jitterRatio: 0.1,
			},
		}),
	],
})
export class AppModule {}

ProviderStatusModule is global by default. Pass isGlobal: false when the service should remain module-local.

Polling starts during Nest application bootstrap by default. The first round runs immediately; later rounds are scheduled after the previous round finishes. Concurrent refreshes for the same provider share one in-flight check, so a slow status page cannot create overlapping requests.

Status model

The normalized provider states are:

operational
degraded
down
maintenance
unknown

Each provider health record keeps two independent signals:

reportedStatus: the last valid public or custom status report;
observedStatus: health inferred from local request outcomes.

The public status is the worst usable result across both. unknown wins only when no known signal exists. A failed refresh does not prove that the provider is down: the last report is retained while sourceState becomes unavailable, and a separate warning is emitted. Once that retained report is stale, it remains visible as reportedStatus for diagnostics but no longer contributes to the effective status; fresh local observations take over, or the effective state becomes unknown.

sourceState is one of not-configured, pending, available, unavailable, or stale. This separation lets a dashboard say “the last OpenAI report was operational, but the status source is currently unreachable” instead of presenting a false outage.

Snapshots include safe provider metadata, selected components, unresolved incidents, freshness, the latest normalized check error, local observation summaries, and warnings. Snapshots and their provider arrays are frozen before publication.

Built-in OpenAI and Anthropic sources

import {
	createAnthropicStatusProvider,
	createOpenAIStatusProvider,
} from "@nestm/provider-status/statuspage";

const openai = createOpenAIStatusProvider();
const anthropic = createAnthropicStatusProvider();

The OpenAI preset uses the separate status, components, and incidents endpoints at status.openai.com and selects server-side API components such as Responses, Chat Completions, embeddings, image generation, audio, files, fine-tuning, Realtime, and Batch. It does not claim to monitor ChatGPT UI availability.

The Anthropic preset uses status.claude.com and selects the Claude API component. It does not claim to monitor claude.ai, Claude Code, or Claude Cowork.

Both presets accept an application-owned fetch implementation and allow component selectors to be replaced:

const openai = createOpenAIStatusProvider({
	id: "openai-primary",
	name: "OpenAI production API",
	components: ["Responses", /^Realtime/],
	fetch: instrumentedFetch,
});

Strings match an exact component ID or name. Regular expressions and matcher functions are also supported. A configured selector must match at least one component by default; otherwise the check is rejected as an invalid report rather than silently monitoring the wrong surface.

Statuspage values are normalized as follows:

Statuspage value	Provider status
`operational`, indicator `none`	`operational`
`degraded_performance`, `partial_outage`, `minor`	`degraded`
`major_outage`, indicator `major` or `critical`	`down`
`under_maintenance`, indicator `maintenance`	`maintenance`
Missing or unrecognized value	`unknown`

Generic Statuspage source

Use a single summary endpoint:

import { createStatuspageProvider } from "@nestm/provider-status/statuspage";

const provider = createStatuspageProvider({
	id: "acme-cloud",
	name: "Acme Cloud",
	statusPageUrl: "https://status.example.com",
	summaryUrl: "https://status.example.com/api/v2/summary.json",
	components: ["Public API"],
	maxIncidents: 3,
});

Or configure the three split Statuspage endpoints with statusUrl, componentsUrl, and incidentsUrl. summaryUrl and the split form are mutually exclusive. requireComponents defaults to true, maxIncidents defaults to three unresolved incidents, and each JSON response is limited to 1 MB by default through the configurable maxResponseBytes option. When component filters are active, incidents without component metadata are excluded to avoid attributing an unrelated product incident to the selected API; set includeUnscopedIncidents: true only when that status page is known to publish globally scoped incidents.

Providers without Statuspage feeds

Any provider can be monitored through a custom check, passive request observations, or both. For example, the Gemini Developer API does not currently expose a dedicated Statuspage-compatible public feed. Monitor real AI SDK calls under a google provider ID, or supply an authoritative application-owned check. Do not treat Google Workspace Gemini or a Vertex AI project-health feed as the Developer API's status unless it is the exact surface the application calls.

Custom providers

A provider is a small application-owned object. Its check method receives a timeout-linked AbortSignal and the ISO timestamp assigned to the attempt:

import type { ProviderStatusProvider, ProviderStatusReport } from "@nestm/provider-status/core";

export const internalAiProvider: ProviderStatusProvider = {
	id: "internal-ai",
	name: "Internal AI gateway",
	statusPageUrl: "https://status.internal.example/ai",
	async check({ signal }): Promise<ProviderStatusReport> {
		const response = await fetch("https://health.internal.example/ai", {
			headers: { accept: "application/json" },
			signal,
		});
		if (!response.ok) throw new Error(`Health endpoint returned ${response.status}.`);

		const result: unknown = await response.json();
		if (
			typeof result !== "object" ||
			result === null ||
			!("healthy" in result) ||
			typeof result.healthy !== "boolean"
		) {
			throw new Error("Health endpoint returned an invalid document.");
		}
		return {
			status: result.healthy ? "operational" : "degraded",
			...("message" in result && typeof result.message === "string"
				? { description: result.message }
				: {}),
		};
	},
};

Only return fields safe for snapshots, dashboards, and SSE clients. Throw when the source itself cannot be checked; do not translate a network failure into down unless it is authoritative evidence about the monitored provider.

Provider IDs must start with an alphanumeric character and may contain letters, numbers, dots, underscores, and hyphens. Duplicate IDs fail during monitor construction.

Passive providers and runtime observations

Omit check when health comes only from real application calls:

ProviderStatusModule.forRoot({
	providers: [{ id: "private-model", name: "Private model service" }],
});

Then record outcomes through ProviderStatusService:

const startedAt = performance.now();

try {
	await callPrivateModel();
	providerStatus.reportSuccess("private-model", {
		latencyMs: performance.now() - startedAt,
		modelId: "private-v2",
	});
} catch (error) {
	providerStatus.reportFailure("private-model", {
		latencyMs: performance.now() - startedAt,
		classification: "network",
	});
	throw error;
}

Set affectsStatus: false for caller cancellation, authentication, billing, quota, invalid input, or another failure that does not demonstrate provider availability. It remains visible as request evidence and can produce a warning without degrading aggregate health.

Providers may also be added and removed at runtime with register() and unregister(). Registering a checked provider while polling is active triggers an immediate refresh.

Module configuration

Synchronous configuration

ProviderStatusModule.forRoot({
	providers: [openai, anthropic, internalAiProvider],
	polling: {
		intervalMs: 60_000,
		timeoutMs: 5_000,
		staleAfterMs: 5 * 60_000,
		jitterRatio: 0.1,
		startOnBootstrap: true,
		unref: true,
	},
	observations: {
		windowMs: 5 * 60_000,
		maxSamples: 200,
		minimumSamples: 10,
		degradedErrorRate: 0.2,
		downErrorRate: 0.5,
		downAfterConsecutiveFailures: 6,
		degradedLatencyMs: 15_000,
	},
	warnings: {
		includeUnknown: true,
		includeSourceUnavailable: true,
		includeStale: true,
		includeRequestErrors: true,
	},
	isGlobal: true,
});

The values above are the defaults except degradedLatencyMs, which is disabled unless explicitly configured because acceptable model latency varies widely. The default stale threshold is the larger of three polling intervals and five minutes. Set polling: false for manual refresh or passive-only monitoring.

Asynchronous configuration

forRootAsync() supports Nest's useFactory, useClass, and useExisting strategies:

import { Module } from "@nestjs/common";
import { ConfigModule, ConfigService } from "@nestjs/config";
import { ProviderStatusModule } from "@nestm/provider-status";
import { createStatuspageProvider } from "@nestm/provider-status/statuspage";

@Module({
	imports: [
		ProviderStatusModule.forRootAsync({
			imports: [ConfigModule],
			inject: [ConfigService],
			useFactory: (config: ConfigService) => ({
				providers: [
					createStatuspageProvider({
						id: "company-ai",
						name: "Company AI",
						statusPageUrl: config.getOrThrow("AI_STATUS_PAGE_URL"),
						summaryUrl: config.getOrThrow("AI_STATUS_SUMMARY_URL"),
						components: ["API"],
					}),
				],
				polling: { intervalMs: config.get("AI_STATUS_INTERVAL_MS", 60_000) },
			}),
		}),
	],
})
export class ObservabilityModule {}

For class-based configuration, implement ProviderStatusOptionsFactory and its createProviderStatusOptions() method.

Service and Observable API

Inject ProviderStatusService for synchronous reads, explicit refreshes, runtime observations, and reactive streams:

import { Injectable } from "@nestjs/common";
import { ProviderStatusService } from "@nestm/provider-status";

@Injectable()
export class AiAvailabilityFacade {
	readonly status$ = this.providerStatus.status$;
	readonly warnings$ = this.providerStatus.warnings$;
	readonly openai$ = this.providerStatus.watch("openai");

	constructor(private readonly providerStatus: ProviderStatusService) {}

	snapshot() {
		return this.providerStatus.getSnapshot();
	}

	refreshOpenAI() {
		return this.providerStatus.refresh("openai");
	}
}

The main API is:

getSnapshot() — current aggregate status, provider records, and warnings;
get(id) / has(id) — inspect registration and current provider health;
status$ — emits the current immutable snapshot immediately and on recomputation;
warnings$ — emits structurally distinct warning arrays;
watch(id) — provider-specific observable;
refresh(id?, { signal? }) — refresh one provider or all providers;
reportSuccess() / reportFailure() — add local call evidence;
isAvailable() / assertAvailable() — evaluate an explicit availability policy;
register() / unregister() — manage application-owned providers dynamically;
start() / stop() — manually control polling when bootstrap control is disabled.

Provider check failures are captured as lastCheckError and source-state warnings; refresh() still resolves with the recomputed snapshot. Invalid or unknown provider IDs continue to throw typed ProviderStatusError instances.

If the caller-provided AbortSignal aborts a refresh, refresh() rejects with that cancellation and leaves provider health unchanged. Lifecycle shutdown cancellation is also health-neutral.

Observation samples expire automatically at the end of the configured sliding window. A passive provider therefore falls back to unknown after its evidence expires; a provider with a fresh public report falls back to that reported state.

Availability evaluates every fresh reported and observed signal independently. Defaults consider operational, degraded, and unknown usable; maintenance and down are unavailable. Override allowDegraded, allowMaintenance, and allowUnknown for stricter policy. assertAvailable() throws ProviderStatusError with code PROVIDER_UNAVAILABLE when any active signal is rejected.

Dashboard HTTP and SSE

Import the optional HTTP module after globally configuring provider status:

import { Module } from "@nestjs/common";
import { ProviderStatusHttpModule } from "@nestm/provider-status/http";

@Module({
	imports: [ProviderStatusHttpModule],
})
export class StatusDashboardModule {}

It exposes:

Route	Response
`GET /provider-status`	Aggregate `ProviderStatusSnapshot`
`GET /provider-status/warnings`	Current warning array
`GET /provider-status/:id`	One provider health record, or HTTP 404
`GET /provider-status/stream`	SSE snapshots plus a 15-second heartbeat

Snapshot events use type provider-status, the snapshot's computedAt value as the event ID, and a five-second reconnect hint. Heartbeats use type provider-status-heartbeat. JSON responses use Cache-Control: no-store.

The plain HTTP module assumes the globally visible ProviderStatusService, which is the default root configuration. For a locally scoped monitor, attach the configured module directly:

ProviderStatusHttpModule.register({
	imports: [
		ProviderStatusModule.forRoot({
			providers: [openai, anthropic],
			polling: { intervalMs: 60_000 },
			isGlobal: false,
		}),
	],
});

No authentication, authorization, tenant filtering, or CORS policy is installed. Protect these routes in the application or at the gateway, especially when provider names, incidents, model IDs, or dependency topology are sensitive. Dashboard clients must render provider and incident text as untrusted content.

AI SDK integration

The optional AI SDK entry point wraps language models and records real call outcomes into the same monitor used by public status sources.

With `@nestm/ai-sdk`

When the application already uses @nestm/ai-sdk, attach the status middleware to its provider registry once. Every language model resolved from that registry is then monitored without wrapping models in individual services.

pnpm add @nestm/provider-status@alpha @nestm/ai-sdk@alpha ai zod \
	@ai-sdk/openai @ai-sdk/anthropic @nestjs/config \
	@nestjs/common@12.0.1 @nestjs/core@12.0.1 \
	reflect-metadata rxjs

import { createAnthropic } from "@ai-sdk/anthropic";
import { createOpenAI } from "@ai-sdk/openai";
import { Injectable, Module } from "@nestjs/common";
import { ConfigModule, ConfigService } from "@nestjs/config";
import { AiSdkModule, AiSdkService } from "@nestm/ai-sdk";
import { ProviderStatusModule } from "@nestm/provider-status";
import {
	ProviderStatusAiSdkModule,
	ProviderStatusAiSdkService,
} from "@nestm/provider-status/ai-sdk";
import { ProviderStatusHttpModule } from "@nestm/provider-status/http";
import {
	createAnthropicStatusProvider,
	createOpenAIStatusProvider,
} from "@nestm/provider-status/statuspage";

@Injectable()
export class ChatService {
	constructor(private readonly ai: AiSdkService) {}

	async complete(prompt: string): Promise<string> {
		const result = await this.ai.generateText({
			model: this.ai.languageModel(),
			prompt,
		});

		return result.text;
	}
}

@Module({
	imports: [
		ConfigModule.forRoot({ isGlobal: true }),
		ProviderStatusModule.forRoot({
			providers: [createOpenAIStatusProvider(), createAnthropicStatusProvider()],
			polling: { intervalMs: 60_000 },
		}),
		AiSdkModule.forRootAsync({
			imports: [ConfigModule, ProviderStatusAiSdkModule],
			inject: [ConfigService, ProviderStatusAiSdkService],
			useFactory: (config: ConfigService, providerHealth: ProviderStatusAiSdkService) => {
				const openai = createOpenAI({
					apiKey: config.getOrThrow<string>("OPENAI_API_KEY"),
				});
				const anthropic = createAnthropic({
					apiKey: config.getOrThrow<string>("ANTHROPIC_API_KEY"),
				});

				return {
					providers: { openai, anthropic },
					registryOptions: {
						languageModelMiddleware: providerHealth.middleware({
							onUnknownProvider: "throw",
						}),
					},
					defaults: { language: "openai:gpt-5-mini" },
				};
			},
		}),
		ProviderStatusHttpModule,
	],
	providers: [ChatService],
	exports: [ChatService],
})
export class AppModule {}

Use registry-resolved models for every monitored call. The default above is returned by ai.languageModel(), while another registered model can be selected explicitly:

const model = this.ai.languageModel("anthropic:claude-sonnet-4-5");
const result = await this.ai.generateText({ model, prompt });

Passing a raw Gateway string or a directly-created provider model to AiSdkService.generateText() bypasses the registry and therefore bypasses this middleware. onUnknownProvider: "throw" detects mapping mistakes; it does not reject calls because a provider is degraded. Add an availability policy as described below when calls should be blocked. ProviderStatusHttpModule exposes the same observations through the dashboard JSON and SSE routes documented above; application services can also consume the reactive warning feed from ProviderStatusService.warnings$.

AI SDK Gateway models remain monitorable when the Gateway is registered in providers and resolved through a registry ID such as gateway:openai/gpt-5-mini. The default resolver maps the first Gateway model-ID segment to the corresponding openai or anthropic status provider.

The registry hook currently monitors language models only. Embedding, image, speech, transcription, reranking, video, files, and skills operations exposed by AiSdkService are not observed by this integration.

With AI SDK directly

Without @nestm/ai-sdk, wrap an application-owned model through the injectable service:

import { Inject, Injectable, Module } from "@nestjs/common";
import { ConfigModule, ConfigService } from "@nestjs/config";
import {
	type MonitorableLanguageModel,
	ProviderStatusAiSdkModule,
	ProviderStatusAiSdkService,
} from "@nestm/provider-status/ai-sdk";
import { createOpenAI } from "@ai-sdk/openai";
import { generateText } from "ai";

const OPENAI_MODEL = Symbol("OPENAI_MODEL");

@Injectable()
export class SummaryService {
	constructor(
		private readonly providerHealth: ProviderStatusAiSdkService,
		@Inject(OPENAI_MODEL) private readonly model: MonitorableLanguageModel,
	) {}

	async summarize(prompt: string): Promise<string> {
		const model = this.providerHealth.wrap(this.model, {
			providerId: "openai",
		});
		const result = await generateText({ model, prompt });
		return result.text;
	}
}

@Module({
	imports: [ConfigModule, ProviderStatusAiSdkModule],
	providers: [
		{
			provide: OPENAI_MODEL,
			inject: [ConfigService],
			useFactory: (config: ConfigService) =>
				createOpenAI({ apiKey: config.getOrThrow("OPENAI_API_KEY") })("gpt-5-mini"),
		},
		SummaryService,
	],
})
export class AiObservabilityModule {}

Applications create and own concrete provider clients. @ai-sdk/openai is shown only as a consumer example and is not installed by this package. ProviderStatusAiSdkModule expects the configured ProviderStatusService to be visible, which the global-by-default root module provides.

ProviderStatusAiSdkService.middleware() returns a native LanguageModelMiddleware; wrap() and wrapLanguageModel() return a wrapped model. The framework-neutral createProviderStatusMiddleware() and monitorLanguageModel() helpers are also exported.

For isGlobal: false, use ProviderStatusAiSdkModule.register({ imports: [...] }) in the same form as the HTTP example so Nest can resolve the local ProviderStatusService.

Provider mapping

Resolution uses this order:

fixed providerId;
application resolveProviderId({ provider, modelId }) callback;
exact providerMap match;
the root of the AI SDK provider string;
for AI SDK Gateway models, the first modelId segment such as openai in openai/gpt-5-mini.

An unresolved or unregistered provider is ignored by default. Set onUnknownProvider: "throw" to fail when model-to-monitor mapping is required.

const monitored = providerHealth.wrap(model, {
	providerMap: {
		"openai.responses": "openai",
		anthropic: "anthropic",
	},
	onUnknownProvider: "throw",
});

Advisory versus enforced availability

Monitoring is advisory by default. With no availability option, the middleware always attempts the AI call and only records its outcome. This is deliberate: a public status page can be stale or wrong, and automatic blocking or fallback can amplify an incident.

To enforce availability before a call, configure the middleware's availability policy:

const enforceAvailability = {
	availability: {
		allowDegraded: false,
		allowMaintenance: false,
		allowUnknown: false,
	},
	onUnknownProvider: "throw",
} as const;

const monitored = providerHealth.wrap(model, {
	providerId: "openai",
	...enforceAvailability,
});

This blocks every state except operational and throws ProviderStatusError before provider I/O. There is intentionally no automatic retry or fallback behavior. If degraded or unknown providers should remain usable, set the corresponding flags to true or keep advisory mode.

The default error classifier treats provider/network availability evidence separately from caller and account errors:

HTTP 5xx, 408, timeouts, and likely network failures affect provider health;
429, authentication, billing, ordinary 4xx configuration errors, caller cancellation, and otherwise unclassified application errors do not;
streaming success is recorded on the terminal finish part, and stream errors are recorded once.

Language-model middleware runs at the provider-attempt level. AI SDK retries happen outside the middleware, so the default maxRetries: 2 can produce as many as three observations for one logical generateText or streamText call. The monitor defaults require six consecutive availability failures before immediately declaring down, but applications should tune thresholds for their retry policy. Set the AI operation's maxRetries: 0 when a strict one-observation-per-logical-call model is required. This package does not add another retry layer.

Custom classification is available through classifyError when a provider has different semantics. The middleware records latency, model ID, status code when available, and a bounded classification; it never reads or stores prompts, responses, tool arguments, or credentials.

Testing

Use the testing entry point to avoid network calls and background polling:

import { Test } from "@nestjs/testing";
import { ProviderStatusService } from "@nestm/provider-status";
import {
	ProviderStatusTestingModule,
	createMemoryProviderStatusProvider,
} from "@nestm/provider-status/testing";

const provider = createMemoryProviderStatusProvider({
	id: "openai",
	name: "OpenAI test provider",
});

const moduleRef = await Test.createTestingModule({
	imports: [ProviderStatusTestingModule.forRoot({ providers: [provider] })],
}).compile();

const status = moduleRef.get(ProviderStatusService);
await status.refresh("openai");

provider.setReport({ status: "degraded", description: "Synthetic degradation." });
await status.refresh("openai");

MemoryProviderStatusProvider also exposes setFailure() and a checks counter. Tests and CI should use fixtures and memory providers rather than live vendor status pages.

Multi-replica deployments

The monitor is intentionally in-memory and process-local. In a multi-replica deployment:

each replica polls independently and keeps its own observation window;
default jitter reduces synchronized polling but does not coordinate replicas;
local AI call evidence and warnings can differ between replicas;
an SSE client sees only the replica holding its connection; and
restarts discard observations and retained public reports.

For a small replica count, independent polling is often acceptable. At larger scale, designate a monitoring replica, use polling: false on other workloads, or supply a custom provider backed by a central collector. Persist or aggregate snapshots outside this package when dashboards require a cluster-wide view. Do not use this in-memory monitor as a distributed circuit breaker.

Security and privacy

Treat all status pages, custom sources, provider names, incident text, and URLs as untrusted input.
Configure source URLs in trusted application infrastructure. If tenant or request data can affect a URL, enforce a strict allowlist and egress policy to prevent SSRF.
Bound and sanitize custom-source output before returning it. Never include raw response bodies, headers, credentials, internal URLs, prompts, responses, or tenant data.
The package creates bounded, non-native check error messages, but custom report fields still belong to the application and may be exposed by HTTP and SSE.
AI observations can expose model IDs, status codes, latency, and failure classification. Decide whether those fields are appropriate for every dashboard audience.
Protect dashboard routes and consider whether publishing dependency and incident details assists attackers or leaks internal topology.
operational is not a guarantee that a request will succeed. A status source can be stale, incomplete, compromised, or unrelated to the exact account, region, model, or API used.
Keep provider degradation separate from host liveness/readiness by default. Explicit readiness coupling can turn a third-party incident into a cascading application outage.
Review retries and fallback independently. They can duplicate tool side effects, move data to a different processor or region, alter model behavior, and increase spend.
