Hey - I've found 3 issues, and left some high level feedback:
- The
RequestyProviderConfigused inAgentOSConfig.createModelProviderManagerConfigpassesmaxRetriesandtimeout, butRequestyProviderConfigonly definesrequestTimeout/streamRequestTimeout—consider aligning the config shape or mapping those fields explicitly so runtime behavior matches expectations. - The
RequestyProvidercurrently logs toconsole.log/console.warn/console.error; if the rest of the codebase uses a centralized logging utility, it would be more consistent and controllable to route these messages through that instead of raw console calls. - In
RequestyProvider.initialize, theUser-Agentis hardcoded toAgentOS/1.0; consider deriving this from a shared constant or package metadata so it stays in sync with the actual AgentOS version.

Please address the comments from this code review:
## Overall Comments
- The `RequestyProviderConfig` used in `AgentOSConfig.createModelProviderManagerConfig` passes `maxRetries` and `timeout`, but `RequestyProviderConfig` only defines `requestTimeout`/`streamRequestTimeout`—consider aligning the config shape or mapping those fields explicitly so runtime behavior matches expectations.
- The `RequestyProvider` currently logs to `console.log`/`console.warn`/`console.error`; if the rest of the codebase uses a centralized logging utility, it would be more consistent and controllable to route these messages through that instead of raw console calls.
- In `RequestyProvider.initialize`, the `User-Agent` is hardcoded to `AgentOS/1.0`; consider deriving this from a shared constant or package metadata so it stays in sync with the actual AgentOS version.

</code_context>
<issue_to_address>
**issue (bug_risk):** Operator precedence in role selection is likely wrong and changes intended behavior.
This expression:
```ts
role: choice.delta?.role || accumulatedToolCalls.size > 0
? 'assistant'
: (choice.message?.role || 'assistant'),
```
actually parses as:
```ts
role: (choice.delta?.role || accumulatedToolCalls.size > 0)
? 'assistant'
: (choice.message?.role || 'assistant');
```
so any truthy `choice.delta?.role` (or `accumulatedToolCalls.size > 0`) forces the role to `'assistant'`, and `delta.role` is never surfaced.
If you meant "use `delta.role` if present, else `'assistant'` when there are tool calls, else `message.role || 'assistant'`", please parenthesize explicitly, e.g.:
```ts
role: choice.delta?.role
?? (accumulatedToolCalls.size > 0
? 'assistant'
: (choice.message?.role ?? 'assistant')),
```
(or equivalent with extra `()` and `||`).

</code_context>
<issue_to_address>
**suggestion:** The abort handler is a no-op and only used to add/remove a listener.
Since all abort behavior is handled via `abortSignal?.aborted` checks in the loop, this listener adds no functional value and its callback never produces side effects. Either remove the listener and rely solely on the per-iteration checks, or make the handler meaningful (e.g., set a local flag and break the loop immediately on abort).
Suggested implementation:
```typescript
const accumulatedToolCalls: Map<number, { id?: string; type?: 'function'; function?: { name?: string; arguments?: string; } }> = new Map();
const abortSignal = options.abortSignal;
if (abortSignal?.aborted) {
yield {
id: `requesty-abort-${Date.now()}`,
object: 'chat.completion.chunk',
created: Math.floor(Date.now() / 1000),
modelId,
choices: [],
error: { message: 'Stream aborted prior to first chunk', type: 'abort' },
isFinal: true,
};
return;
}
```
1. Ensure that elsewhere in this streaming method, you continue to check `abortSignal?.aborted` inside the main loop to handle mid-stream aborts.
2. If there is any corresponding `abortSignal?.removeEventListener('abort', abortHandler)` in a `finally` block or cleanup path, remove it as well to avoid referencing the deleted handler.

</code_context>
<issue_to_address>
**issue (complexity):** Consider introducing small helper types and functions (for config, payload building, streaming, tool-call accumulation, and error normalization) to make this provider’s behavior clearer while reducing duplication and inline branching.
You can cut a fair amount of cognitive load here with a few small extra helpers, without changing behavior.
---
### 1. Config typing / initialization
The `Readonly<Required<Omit<...>>> & RequestyProviderConfig` intersection makes it hard to see what the runtime shape is.
You can define a concrete internal type and keep the same defaults/behavior:
```ts
interface InternalRequestyConfig {
apiKey: string;
baseURL: string;
defaultModelId?: string;
siteUrl?: string;
appName?: string;
requestTimeout: number;
streamRequestTimeout: number;
}
private config!: Readonly<InternalRequestyConfig>;
```
Then in `initialize`:
```ts
public async initialize(config: RequestyProviderConfig): Promise<void> {
// ... apiKey guard, etc.
const internalConfig: InternalRequestyConfig = {
apiKey: config.apiKey,
baseURL: config.baseURL || 'https://router.requesty.ai/v1',
defaultModelId: config.defaultModelId,
siteUrl: config.siteUrl,
appName: config.appName,
requestTimeout: config.requestTimeout ?? 60000,
streamRequestTimeout: config.streamRequestTimeout ?? 180000,
};
this.config = Object.freeze(internalConfig);
this.keyPool = new ApiKeyPool(this.config.apiKey);
this.defaultModelId = this.config.defaultModelId;
// ...
}
```
This keeps the runtime shape explicit and removes the `Omit`/`Required` intersection.
---
### 2. Duplicated completion payload construction
`generateCompletion` and `generateCompletionStream` differ only in streaming flags and timeout. You can pull the payload into a shared helper so that max_tokens / tools / response_format etc. live in one place:
```ts
private buildChatCompletionPayload(
modelId: string,
messages: ChatMessage[],
options: ModelCompletionOptions,
stream: boolean
): Record<string, unknown> {
const requestyMessages = this.mapToRequestyMessages(messages);
return {
model: modelId,
messages: requestyMessages,
stream,
...(stream && { stream_options: { include_usage: true } }),
temperature: options.temperature,
top_p: options.topP,
max_tokens: clampMaxOutputTokens(modelId, options.maxTokens) ?? 4096,
presence_penalty: options.presencePenalty,
frequency_penalty: options.frequencyPenalty,
stop: options.stopSequences,
user: options.userId,
tools: options.tools,
tool_choice: options.toolChoice,
...(options.responseFormat?.type === 'json_object' && {
response_format: { type: 'json_object' },
}),
...(options.customModelParams || {}),
};
}
```
Then use it:
```ts
public async generateCompletion(...) {
this.ensureInitialized();
const payload = this.buildChatCompletionPayload(modelId, messages, options, false);
const apiResponseData = await this.makeApiRequest<RequestyChatCompletionAPIResponse>(
'/chat/completions',
'POST',
options.requestTimeout ?? this.config.requestTimeout,
payload
);
return this.mapApiToCompletionResponse(apiResponseData, modelId);
}
public async *generateCompletionStream(...) {
this.ensureInitialized();
const payload = this.buildChatCompletionPayload(modelId, messages, options, true);
const stream = await this.makeApiRequest<NodeJS.ReadableStream>(
'/chat/completions',
'POST',
options.requestTimeout ?? this.config.streamRequestTimeout,
payload,
true
);
// ...
}
```
---
### 3. Stream chunk handling / SSE loop
`generateCompletionStream` currently mixes abort handling, SSE parsing, DONE detection, JSON parsing, and mapping. That can be moved into a single helper to make the orchestration method easier to scan:
```ts
private async *processCompletionStream(
stream: NodeJS.ReadableStream,
modelId: string,
options: ModelCompletionOptions
): AsyncGenerator<ModelCompletionResponse, void, undefined> {
const accumulatedToolCalls = new Map<number, { id?: string; type?: 'function'; function?: { name?: string; arguments?: string; } }>();
const abortSignal = options.abortSignal;
const abortHandler = () => {};
abortSignal?.addEventListener('abort', abortHandler, { once: true });
try {
if (abortSignal?.aborted) {
yield this.makeAbortChunk(modelId, 'Stream aborted prior to first chunk');
return;
}
for await (const rawChunk of this.parseSseStream(stream)) {
if (abortSignal?.aborted) {
yield this.makeAbortChunk(modelId, 'Stream aborted by caller');
break;
}
if (rawChunk === 'data: [DONE]' || (rawChunk.startsWith('data: ') && rawChunk.trim().endsWith('[DONE]'))) {
break;
}
if (!rawChunk.startsWith('data: ')) continue;
const jsonData = rawChunk.substring('data: '.length);
try {
const apiChunk = JSON.parse(jsonData) as RequestyChatCompletionAPIResponse;
yield this.mapApiToStreamChunkResponse(apiChunk, modelId, accumulatedToolCalls);
} catch (err) {
console.warn('RequestyProvider: Failed to parse stream chunk JSON, skipping chunk. Data:', jsonData, 'Error:', err);
}
}
} finally {
abortSignal?.removeEventListener('abort', abortHandler);
}
}
```
Then `generateCompletionStream` reduces to:
```ts
public async *generateCompletionStream(...) {
this.ensureInitialized();
const payload = this.buildChatCompletionPayload(modelId, messages, options, true);
const stream = await this.makeApiRequest<NodeJS.ReadableStream>(
'/chat/completions',
'POST',
options.requestTimeout ?? this.config.streamRequestTimeout,
payload,
true
);
yield* this.processCompletionStream(stream, modelId, options);
}
```
This keeps the happy-path orchestration linear and pushes low-level SSE concerns into one place.
---
### 4. Stream tool-call accumulation
`mapApiToStreamChunkResponse` is doing both tool-call accumulation and final/delta message mapping. Extracting the accumulation into a small helper makes the function easier to reason about:
```ts
private updateToolCalls(
accumulated: Map<number, { id?: string; type?: 'function'; function?: { name?: string; arguments?: string; } }>,
toolCallDeltas: NonNullable<RequestyChatChoice['delta']>['tool_calls']
): ModelCompletionResponse['toolCallsDeltas'] {
const toolCallsDeltas: NonNullable<ModelCompletionResponse['toolCallsDeltas']> = [];
for (const tcDelta of toolCallDeltas) {
let current = accumulated.get(tcDelta.index) ?? { function: { name: '', arguments: '' } };
if (tcDelta.id) current.id = tcDelta.id;
if (tcDelta.type) current.type = 'function';
if (tcDelta.function?.name) current.function!.name += tcDelta.function.name;
if (tcDelta.function?.arguments) current.function!.arguments += tcDelta.function.arguments;
accumulated.set(tcDelta.index, current);
toolCallsDeltas.push({
index: tcDelta.index,
id: tcDelta.id,
type: 'function',
function: tcDelta.function && {
name: tcDelta.function.name,
arguments_delta: tcDelta.function.arguments,
},
});
}
return toolCallsDeltas;
}
```
Then in `mapApiToStreamChunkResponse`:
```ts
let toolCallsDeltas: ModelCompletionResponse['toolCallsDeltas'];
if (choice.delta?.tool_calls) {
toolCallsDeltas = this.updateToolCalls(accumulatedToolCalls, choice.delta.tool_calls);
}
```
This pulls the mutation logic out of the already-branchy mapping code.
---
### 5. Error normalization
`makeApiRequest` has substantial error-shaping logic. Pulling that into a helper clarifies the main method:
```ts
private normalizeAxiosError(error: unknown, endpoint: string, body?: Record<string, unknown>) {
let statusCode: number | undefined;
let errorData: any;
let message = 'Unknown Requesty API error';
let type = 'UNKNOWN_API_ERROR';
if (axios.isAxiosError(error)) {
statusCode = error.response?.status;
errorData = error.response?.data;
if (errorData?.error && typeof errorData.error === 'object') {
message = errorData.error.message || message;
type = errorData.error.type || type;
} else if (typeof errorData === 'string') {
message = errorData;
} else if ((error as Error).message) {
message = (error as Error).message;
}
} else if (error instanceof Error) {
message = error.message;
}
const decoratedMessage = statusCode ? `[${statusCode}] ${message}` : message;
return {
statusCode,
errorData,
errorType: type,
decoratedMessage,
details: {
requestEndpoint: endpoint,
requestBodyPreview: body ? JSON.stringify(body).substring(0, 200) + '...' : undefined,
responseData: errorData,
underlyingError: error,
},
};
}
```
And in `makeApiRequest`:
```ts
} catch (error: unknown) {
const { statusCode, errorType, decoratedMessage, details } =
this.normalizeAxiosError(error, endpoint, body);
throw new RequestyProviderError(
decoratedMessage,
'API_REQUEST_FAILED',
statusCode,
errorType,
details
);
}
```
---
### 6. Non‑null assertions on `c.message`
`mapApiToCompletionResponse` assumes `message` is always present but uses `!`. Either tighten `RequestyChatChoice` for non-stream responses, or add a small guard:
```ts
const choices = apiResponse.choices.map(c => {
if (!c.message) {
throw new RequestyProviderError(
"Received choice without message in non-stream response.",
"API_RESPONSE_MALFORMED",
undefined,
undefined,
{ responseId: apiResponse.id, choiceIndex: c.index }
);
}
return {
index: c.index,
message: {
role: c.message.role,
content: c.message.content,
tool_calls: c.message.tool_calls,
},
finishReason: c.finish_reason,
logprobs: c.logprobs,
};
});
```
Then:
```ts
return {
id: apiResponse.id,
object: apiResponse.object,
created: apiResponse.created,
modelId: apiResponse.model || requestedModelId,
choices,
usage,
};
```
This removes the non-null assertion and makes the assumption explicit.

In `@src/core/config/AgentOSConfig.ts`:
- Around line 236-248: The Requesty provider configuration block is using
incorrect field names that do not match what RequestyProviderConfig expects. In
the config object within the Requesty provider block, rename the field
`defaultModel` to `defaultModelId` and rename the field `timeout` to
`requestTimeout` to ensure these configuration values are properly read by the
RequestyProvider instead of being silently ignored.
- Line 52: The new REQUESTY_API_KEY field has been added to the AgentOSConfig
interface, but the validation logic that checks for "no LLM provider configured"
warning does not include this new key in its condition. Find the warning
condition that validates whether at least one LLM provider is configured (likely
checking other API keys like OPENAI_API_KEY, ANTHROPIC_API_KEY, etc.) and add
REQUESTY_API_KEY to that check so that a Requesty-only deployment does not
trigger the warning.
In `@src/core/llm/providers/implementations/RequestyProvider.ts`:
- Around line 701-707: Remove the requestBodyPreview property from the error
object passed to RequestyProviderError in the throw statement, as it exposes
sensitive user data like prompts and tool arguments. Keep only the safe
properties like requestEndpoint, responseData, and underlyingError in the error
context.
- Around line 401-412: The issue is that customModelParams is spread directly
onto the root payload object, but the code then attempts to write inputType to
payload.customModelParams, creating a new nested structure that won't be sent in
the request. Instead of conditionally assigning to payload.customModelParams,
directly assign the input_type property to the root payload object when
options?.inputType exists, similar to how encoding_format and dimensions are
already being handled via the spread operator pattern.
- Around line 336-384: The abort signal handling in the stream method has two
issues: first, the abort check happens after makeApiRequest is already called,
so already-aborted signals don't prevent the API request, and second, the
removeEventListener call is unprotected and won't execute if the stream loop
throws an error. Move the abort signal check to occur before calling
makeApiRequest on the stream so that aborted calls don't hit the API, and wrap
both the stream loop and the removeEventListener cleanup in a try-finally block
to ensure the listener is always removed even if an error occurs during
streaming.

- Around line 116-118: Update the overlapping-property branch in
ensureAnthropicObjectSchema so that when a key already exists in
mergedProperties, the existing schema and incoming propSchema are preserved
together in a nested anyOf instead of discarding the later schema; retain the
current assignment behavior for new keys and enum-specific handling.

…m error contract, abort, embeddings payload)
…single final stream chunk, sanitize error details Address the second review round on the Requesty provider: Authorization is now set per request from apiKeyOverride or the key pool instead of being fixed on the axios instance at initialize(). options.abortSignal is forwarded to axios so an abort settles a pending request; an aborted stream now yields an abort chunk instead of api_error. The finish_reason chunk is buffered and merged with the trailing usage chunk so exactly one chunk per stream carries isFinal:true. Malformed SSE data throws STREAM_CHUNK_MALFORMED (the outer catch turns it into the terminal error chunk) and only the payload length is recorded. Non stream responses reject choices without a message object with API_RESPONSE_MALFORMED. Error details keep only name, code and message of the underlying error instead of the raw axios error that carries the Authorization header. Ollama is no longer marked default when only REQUESTY_API_KEY is set.

In `@src/core/llm/providers/implementations/RequestyProvider.ts`:
- Around line 467-476: Validate apiResponseData.data and apiResponseData.usage
before dereferencing them in the embeddings response mapping path. When either
field is missing or malformed, raise API_RESPONSE_MALFORMED consistently with
mapApiToCompletionResponse instead of allowing a raw TypeError; preserve the
existing mapping for valid responses.
- Around line 414-417: Update the stream-finalization logic around pendingFinal
to track whether any terminal chunk with isFinal: true was emitted; when [DONE]
or EOF is reached without finish_reason or a usage-only chunk, synthesize and
yield one terminal chunk, while preserving the existing pendingFinal emission
path.
- Around line 231-232: Update mapApiToModelInfo so the API model pricing field
is optional and access prompt and completion through optional chaining before
passing them to parsePrice, allowing models without pricing to map successfully.

Add Requesty as an OpenAI-compatible LLM provider
This adds a native
RequestyProviderto the LLM provider system, mirroring theexisting
OpenRouterProvideras closely as possible. Requestyis an OpenAI-compatible LLM gateway (base URL
https://router.requesty.ai/v1)that exposes models from many upstreams under
provider/modelnaming(e.g.
openai/gpt-4o-mini), the same aggregator shape AgentOS already supportsfor OpenRouter.
What's added
src/core/llm/providers/implementations/RequestyProvider.ts: a fullIProviderimplementation, a faithful copy ofOpenRouterProvider:axios client,
RequestyProviderConfig(apiKey,baseURL?,defaultModelId?,siteUrl?,appName?, timeouts), default base URLhttps://router.requesty.ai/v1,chat completions (sync + streaming with
stream_options.include_usage),embeddings, model listing, health check, and
clampMaxOutputTokensfrommodel-output-limits. Because Requesty is OpenAI-compatible exactly likeOpenRouter, all request/response/embeddings/error logic is identical. The
optional
HTTP-Referer/X-Titleheaders (fromsiteUrl/appName) arepreserved, Requesty accepts them too.
src/core/llm/providers/errors/RequestyProviderError.ts: error classmirroring
OpenRouterProviderError(same shape,providerId: 'requesty').Wiring sites
AIModelProviderManager.ts: added theRequestyProvider/RequestyProviderConfigimport, theRequestyProviderConfigmember of theprovider-config union, and a
case 'requesty':to the factory switch.structuredOutputFormat.ts: addedcase 'requesty':to the same branch asopenrouter, best effortjson_object, since an aggregator may not enforce aJSON schema across all upstreams (caller-side Zod validation still runs).
model-output-limits.ts: no change needed, theprovider/prefix strippingis already generic (
/^[^/]+\//) and handles Requesty'sprovider/modelidsidentically to OpenRouter's.
AgentOSConfig.ts: added theREQUESTY_API_KEYenv field/passthrough and aprovider registration block (mirrors the OpenRouter one) so a
REQUESTY_API_KEYis auto-wired into the manager.
Verification
tsc --noEmit(pnpm run typecheck) passes cleanly.https://router.requesty.ai/v1/chat/completionswith
openai/gpt-4o-minireturned HTTP 200 and a real completion.Review follow ups
apiKeyOverride,abortSignalforwarded to axios, a singleisFinalchunk per stream, malformed SSE data surfaced as a terminal error, and sanitized error details.pricingon/modelsentries, synthesized terminal chunk when a stream ends withoutfinish_reason, embeddings response validation withAPI_RESPONSE_MALFORMED. Each has a unit test inrequesty-response-shape.test.ts.Docs: https://requesty.ai · https://docs.requesty.ai
This mirrors the existing OpenRouter provider as closely as possible.
Disclosure: I work at Requesty. Happy to adjust anything to match project conventions.
