Greptile Overview

Greptile Summary

Extends Azure Anthropic support across blocks/tools by surfacing Azure endpoint/API version credential fields in block UIs and threading those credentials through router/evaluator/guardrails request paths.
Adds azure-anthropic to Copilot’s allowed provider set/types and wires env-based AZURE_ANTHROPIC_* config into the Copilot chat route.
Updates tokenization config/estimators so azure-anthropic uses Anthropic-style heuristics.
Adjusts the azure-anthropic provider to respect azureApiVersion for the anthropic-version header.

Confidence Score: 3/5

This PR is close to merge-ready but has at least one functional request-shape issue that can break Router/Evaluator provider calls in strict-validation paths.
Most changes are additive and consistent (env vars, types, tokenization, provider header). The main concern is the router/evaluator handlers now always including provider-specific credential fields regardless of provider, which can cause downstream validation or provider execution failures depending on the /api/providers schema and provider adapters.
apps/sim/executor/handlers/router/router-handler.ts; apps/sim/executor/handlers/evaluator/evaluator-handler.ts

Important Files Changed

Filename	Overview
apps/sim/app/api/copilot/chat/route.ts	Adds azure-anthropic env-based providerConfig wiring for copilot chat route.
apps/sim/app/api/guardrails/validate/route.ts	Threads providerCredentials + workspaceId through guardrails validate endpoint into validateHallucination; no new obvious issues found in this file.
apps/sim/blocks/blocks/agent.ts	Extends Azure endpoint/API version subblocks to include azure-anthropic models and updates placeholders/descriptions.
apps/sim/blocks/blocks/translate.ts	Fixes bedrock credential mapping (adds missing bedrockAccessKeyId to tool params).
apps/sim/executor/handlers/evaluator/evaluator-handler.ts	Now always includes azure/vertex/bedrock credential fields in providerRequest; may violate provider request schema if strict.
apps/sim/executor/handlers/router/router-handler.ts	Now always includes azure/vertex/bedrock credential fields in providerRequest for both legacy and v2 router requests; likely breaks strict validation or downstream provider expectations.
apps/sim/lib/copilot/config.ts	Adds azure-anthropic to VALID_PROVIDER_IDS for copilot config parsing.
apps/sim/lib/copilot/types.ts	Adds CopilotProviderConfig variant for azure-anthropic with apiVersion/endpoint fields; resolves earlier missing apiVersion thread.
apps/sim/lib/core/config/env.ts	Adds AZURE_ANTHROPIC_* env vars for endpoint/apiKey/apiVersion.
apps/sim/lib/guardrails/validate_hallucination.ts	Adds providerCredentials/workspaceId support and resolves Vertex OAuth token inside scoring function before provider call; removes earlier getApiKey pre-check.
apps/sim/lib/tokenization/constants.ts	Adds azure-anthropic to tokenization config constants.
apps/sim/lib/tokenization/estimators.ts	Routes azure-anthropic token estimation through Anthropic estimator.
apps/sim/providers/azure-anthropic/index.ts	Uses request.azureApiVersion as anthropic-version header (fallback 2023-06-01).
apps/sim/tools/guardrails/validate.ts	Extends guardrails_validate tool to accept and forward azure/vertex/bedrock credential fields and context workspaceId/workflowId.
apps/sim/blocks/utils.ts	Updates getProviderCredentialSubBlocks to include azure-anthropic models in azureEndpoint/azureApiVersion conditions and adjusts labels/placeholders.

apps/sim/lib/guardrails/validate_hallucination.ts
Spreading undefined credentials

scoreHallucinationWithLLM spreads ...providerCredentials into the provider request, but providerCredentials is optional and can be undefined (e.g., most callers won’t pass Azure/Vertex/Bedrock fields). Spreading undefined throws at runtime (TypeError: Cannot convert undefined or null to object), which will make hallucination validation fail for those requests.

This needs to guard the spread (e.g., ...(providerCredentials ?? {})) or otherwise ensure providerCredentials is always a defined object before spreading.

apps/sim/blocks/blocks/agent.ts
Wrong endpoint description

In inputs, azureEndpoint is still documented as 'Azure OpenAI endpoint URL', but this PR reuses the same field for both azure-openai and azure-anthropic (and the UI label was changed to “Azure Endpoint”). This mismatch will cause incorrect tool schema/help text and can confuse users configuring Azure Anthropic.

Update the description to a provider-agnostic Azure endpoint (matching the new shared usage).

- Pass all provider credentials unconditionally in router, evaluator (matching agent pattern) - Remove conditional if-branching on providerId for credential fields - Thread workspaceId through guardrails → hallucination validator for BYOK key resolution - Remove getApiKey() from hallucination validator, let executeProviderRequest handle it - Resolve vertex OAuth credentials in hallucination validator matching agent handler pattern Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

apps/sim/executor/handlers/router/router-handler.ts
Unconditional provider creds sent

providerRequest always includes azureEndpoint/azureApiVersion, vertexProject/vertexLocation, and bedrock* fields regardless of providerId (see providerRequest construction around this block). This can cause /api/providers to receive irrelevant credential fields (and even undefined values) for non-matching providers, which will break if the providers route validates payload shape strictly or forwards these into provider SDKs that reject unknown/empty fields.

Fix by only attaching the credential fields for the active provider (as the code did before this PR), or by ensuring the /api/providers request schema explicitly tolerates these extra fields across all providers.
