Eval | Replace Octavus with a Claude API provider - #1
Conversation
Co-authored-by: Cursor <cursoragent@cursor.com>
📝 WalkthroughWalkthroughThe project replaces Octavus session execution with independent Anthropic Merge Risk: 🔴 Critical · up to This PR switches evaluations to direct Anthropic API calls and adds new transport and UUID-generation behavior. Merge should be blocked until the required FedRAMP/FIPS validation confirms approved cryptography and certificate handling; otherwise affected deployments could face compliance or security issues, while provider misconfiguration may also produce failed requests without a proper configuration response. 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

Complete the required FedRAMP significant-change assessment before merge.
This PR adds a new Anthropic API-key/TLS transport path and introduces UUID generation through Node’s crypto module. Confirm that deployed cryptography, randomness, and certificate validation use approved FIPS-validated implementations for both paths.

🌐 Web query:
For @anthropic-ai/sdk version 0.123.0, does client.messages.create() expose the HTTP request ID as _request_id, distinct from message.id?
💡 Result:
Yes, for @anthropic-ai/sdk version 0.123.0, the client.messages.create method returns an object that exposes the HTTP request ID via a _request_id property [1][2]. This property is distinct from the message.id, which identifies the message object itself within the Anthropic API [3][4]. The _request_id is populated from the request-id response header, allowing for easier logging and debugging of specific API requests [1][5].

Return the HTTP request ID instead of the Message ID.
message.id identifies the generated Message. client.messages.create() exposes the HTTP request ID as _request_id, populated from the response header. Use _request_id for provider-log correlation.

For Express 4.19.2, are errors thrown in an async route handler automatically forwarded to error middleware?
💡 Result:
No, in Express 4.19.2, errors thrown in an async route handler are not automatically forwarded to error middleware [1][2][3]. In Express 4, the built-in router only automatically catches and propagates errors that occur synchronously [2][4]. If an error occurs within an async function—either by throwing an exception or returning a rejected promise—the error is not caught by Express, which typically results in an unhandled promise rejection [1][2][4]. To handle errors in async route handlers in Express 4.19.2, you must explicitly catch the errors and pass them to the next function [1][3]. Common approaches include: 1. Wrapping the route handler logic in a try/catch block and calling next(err) in the catch block [1][2][3]. 2. Using a wrapper function (like express-async-handler) to automatically catch errors and pass them to next [5][6][4]. 3. Using the express-async-errors package, which patches the Express 4 router to provide automatic error propagation for async handlers [6][4]. This behavior differs from Express 5, which does automatically catch and propagate rejected promises and errors from async functions to the error middleware [7][8][2].

Handle provider-configuration errors before the route promise rejects.
When ANTHROPIC_API_KEY is set and LLM_PROVIDER is unsupported, createLlmProvider() throws from getLlm() before either evaluation route enters its try block. Express 4 does not forward this rejection to error middleware. Catch it and return a configuration error, or pass it to next(err).

Summary
Eval runs now call the Anthropic Messages API directly instead of creating Octavus agent sessions.
Changes
The interesting part is
lib/llm/: a small provider factory with Anthropic as the only implementation.LLM_PROVIDERdefaults toanthropicand unknown values throw, so a later OpenAI PR can add a case without touching eval-run.Each eval run is one
complete()call usingagents/prompt-eval/prompts/system.mdplus the rendered user prompt. We still return a localsessionIdso the existing result JSON stays stable.Leftover Cosmo chat routes that used to create or stream Octavus sessions now return 501 so the Octavus packages can go away. Local session list/save/delete stay as-is. I left the unused Cosmo helpers (
thinking.js,stream-registry.js,model-capabilities.js) alone on purpose.Config is
