…ng sample - Fixed BaseURL in main.go to use proper HTTPS protocol - Removed hardcoded API key from tool_calling.go, now uses environment variables - Deleted duplicate tool-calling-sample directory (functionality exists in sample-app) - Removed binary files from repository 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
The tool calling functionality is already implemented in sample-app/tool_calling.go, so the duplicate directory is not needed. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
1. Add omitempty to Tool struct Function field for optional serialization 2. Add toolCall.Type attribute propagation in span attributes 3. Add error logging for JSON marshaling failures in setToolsAttribute 4. Improve temperature unit validation in tool calling sample These changes improve error handling, completeness of tracing attributes, and robustness of the tool calling implementation. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
HTTP Mocking Features: - Manual HTTP mocking using httptest (no API keys needed) - VCR recording with pre-sanitized mock cassette - Integration test support with environment variable gating - Comprehensive testing documentation Security Features: - Authorization headers automatically sanitized from recordings - Pre-sanitized mock cassette included for CI - Gitignore configured to prevent accidental key commits - Request body sanitization for extra safety CodeRabbit Review Fixes: - Add omitempty to Tool struct Function field for optional serialization - Add toolCall.Type propagation in both span attribute functions - Add error logging for JSON marshaling failures in setToolsAttribute - Improve temperature unit validation with proper error handling All tests pass without requiring API keys, making CI/CD pipeline friendly. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
- Remove manual HTTP mocking approach - VCR is more realistic - Keep only VCR recording with pre-sanitized cassette - Update documentation to focus on single testing approach - All tests pass without requiring API keys in CI 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
The go.opentelemetry.io/otel/exporters/stdout/stdouttrace dependency was not used in any Go files and has been removed to clean up the dependency tree. All tests continue to pass after this cleanup. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
The root go.mod had incorrect require syntax with missing version numbers and improper quotes, causing CI test failures. Fixed with: - Proper version numbers for local modules - Added replace directives for local development - Removed quotes from module names CI tests now run successfully for both sample-app and traceloop-sdk. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

3. sample-app/README.md:3
- Draft comment:
It appears that "OpenLLMetry" may be a typographical error. Did you mean "OpenTelemetry"? Please double-check for consistency. - Reason this comment was not posted:
Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 10% vs. threshold = 50% The name "OpenLLMetry" appears to be a deliberate portmanteau combining "LLM" and "Telemetry". The context is about LLM tooling (OpenAI, tool calling, prompt logging). The comment assumes it's a typo but it's likely an intentional branding choice. Making assumptions about product names without being certain is risky. I could be wrong about this being intentional - maybe it really is a typo. The standard OpenTelemetry project is very well-known. Even if there's a small chance it's a typo, we shouldn't make assumptions about product names without strong evidence. The context strongly suggests this is LLM-related tooling. Delete this comment as it's making assumptions about what might be an intentional product name without strong evidence that it's actually incorrect.
4. traceloop-sdk/go.sum:66
- Draft comment:
I noticed that the module name "github.com/traceloop/go-openllmetry/semconv-ai" might contain a typographical error. Should it be "go-opentelemetry" (with a single 'l') instead of "go-openllmetry"? - Reason this comment was not posted:
Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 0% vs. threshold = 50% This appears to be an intentional module name from the traceloop organization. The "ll" in "openllmetry" likely stands for something specific (perhaps "large language" given the "ai" in the path). This isn't a typo - it's a deliberate naming choice. Making assumptions about package names being typos without understanding the context is dangerous. I could be wrong about the meaning of "ll" in the name. Maybe it really is a typo that should be fixed. Given this is from the organization's own repository and follows their naming pattern, it's extremely unlikely to be a typo. If it were a typo, it would likely have been caught during the initial module creation. The comment should be deleted as it incorrectly assumes a deliberate module name is a typo.
5. traceloop-sdk/sdk_test.go:11
- Draft comment:
Typo alert: The import path 'github.com/traceloop/go-openllmetry/traceloop-sdk/config' contains 'openllmetry'. If this is intended to reference OpenTelemetry, it might be meant to be spelled 'opentelemetry'. Please double-check. - Reason this comment was not posted:
Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 10% vs. threshold = 50% This appears to be an intentional naming choice, not a typo. The package seems to be specifically about LLMs (hence 'openllmetry' combining 'open' and 'llm'), and is building on top of OpenTelemetry for LLM-specific telemetry. The import paths for actual OpenTelemetry packages are correct (go.opentelemetry.io/otel). This is likely a deliberate name for a new project. I could be wrong about the intention - maybe it really is a typo that should be fixed. The similarity to 'opentelemetry' is very close. The consistent use of 'llm' throughout the code and the fact that this is clearly an LLM-focused package strongly suggests this is an intentional name combining 'open' and 'llm'. The comment should be deleted as it's pointing out what appears to be an intentional package naming choice, not a typo that needs fixing.

traceloop-sdk/utils.go (1)
22-26: Ensure BaseURL Is Valid and Safely Construct URLsString-concatenation with
fmt.Sprintf("%s/%s", BaseURL, path)can produce double-slashes and, if the user omits a scheme, end up with an invalid request (a schemeless URL will pass throughhttp.NewRequestbut fail at send time). We should:
- Parse and normalize
instance.config.BaseURL, enforcing a default scheme if missing.- Use the
net/urlAPIs (ResolveReferenceorJoinPath) to append the resource path cleanly.- Return a wrapped error on invalid BaseURL or request creation.

49-49: Guard against empty choices to avoid panicDirectly indexing resp.Choices[0] can panic on empty results or filtered responses.
Example:
if len(resp.Choices) == 0 { fmt.Println("No choices returned") return } fmt.Println(resp.Choices[0].Message.Content)
🧹 Nitpick comments (10)
go.mod (1)
6-12: Local replaces: fine for dev, but gate for release; consider go.workUsing local replace directives with placeholder pseudo-versions is OK for iterative dev. Before releasing/publishing, drop these replaces or move to a workspace (go.work) to avoid accidental coupling and to enable consumers to resolve proper versions.
Action:
- Verify CI/builds don’t rely on these replaces unintentionally.
- Consider adopting a top-level go.work to manage the multi-module layout cleanly across the repo and sample app.
traceloop-sdk/go.mod (1)
10-10: Local development flow for semconv-aiThis module requires github.com/traceloop/go-openllmetry/semconv-ai at a pseudo-version. If you intend to build this submodule standalone, add a replace here or manage via a repository-level go.work so local changes are picked up consistently (currently only the root go.mod includes replaces).
sample-app/.gitignore (1)
1-4: Good safeguard for VCR artefacts; add minimal guidance filePattern looks good and prevents leaking raw cassettes. Consider adding testdata/README.md with sanitization rules so future contributors don’t accidentally commit new unsanitized files.
sample-app/go.mod (2)
12-55: Tidy and deduplicate indirectsRun 'go mod tidy' to prune unnecessary indirect dependencies and reduce duplicate packages (e.g., both cenkalti/backoff and cenkalti/backoff/v4 are present). This keeps the module lean and avoids version conflicts.
Command:
- go mod tidy -v
57-60: Replace directives are fine; consider conditional setup for external consumersLocal replaces are appropriate for this PR. If this sample is consumed outside the mono-repo, document or gate these replaces (e.g., via build tags or separate example module) to avoid confusion.
sample-app/testdata/tool_calling_cassette.yaml (1)
13-15: Avoid brittle headers in cassettesUser-Agent includes the exact client version (alpha.35). Upgrading the SDK may tempt re-recording or cause confusion. Consider filtering User-Agent from recorded headers to make cassettes future-proof.
If using go-vcr, you can configure header filtering before saving the cassette.
traceloop-sdk/sdk_test.go (1)
26-33: Use the public constructor to decouple the test from struct internalsThe test manually instantiates
Traceloopand fills only two fields.
If the struct gains new required fields, this test will panic silently. Prefer:tl := sdk.NewClient(config.Config{BaseURL: "...", APIKey: "test-key"}) tl.TracerProviderOverride(tp) // or export the field temporarilyThis keeps the test resilient to future changes in
Traceloop.sample-app/tool_calling_test.go (1)
55-56: Disable SDK polling in unit tests
traceloop.Initializelaunches the prompt-polling loop which performs network I/O every 5 s.
For a pure unit test it is unnecessary noise and can slow the suite. Consider:traceloop.SkipPolling = true // or inject a nil/Mock pollersample-app/tool_calling.go (1)
66-91: Minor duplication between tool definition helpers
createWeatherToolandconvertToolsToDTOrepeat the same JSON schema.
Returning the schema once and re-using it would cut maintenance effort.traceloop-sdk/sdk.go (1)

traceloop-sdk/go.mod (1)
3-5: Toolchain bump: ensure CI and dev envs support Go 1.23The module declares go 1.23.0 and toolchain go1.23.12. Verify CI uses GOTOOLCHAIN=auto or Go 1.23+ to avoid build surprises, especially since the root module targets go 1.21.
sample-app/main.go (1)
17-21: CLI arg check works; consider using flag parsing and passing contextThe "tool-calling" branch is fine for a sample. For robustness:
- Prefer the standard flag package to allow future flags without breaking arg order.
- Consider passing ctx into runToolCallingExample for consistent cancellation handling.
- Ensure runToolCallingExample initializes and shuts down Traceloop on its own, since this branch returns early.
Would you like me to refactor this to use flag and thread ctx through runToolCallingExample?
sample-app/README.md (1)
25-29: Doc-code alignment for TRACELOOP_BASE_URLREADME documents TRACELOOP_BASE_URL (optional), but main.go currently hardcodes the BaseURL. Please ensure code reads this env var with fallback to production so the doc remains accurate.
I proposed the corresponding code change in main.go to honor this variable.
sample-app/go.mod (1)
5-10: Confirm need for both OpenAI clientsYou're depending on both github.com/openai/openai-go and github.com/sashabaranov/go-openai. If the intent is to use openai-go for tool-calling and keep go-openai for the basic sample, that's fine. Otherwise, drop the unused one to reduce surface area.
Do both samples require separate clients? If not, I can refactor to a single client.
sample-app/testdata/tool_calling_cassette.yaml (1)
6-7: Tool function name “get_weather” is consistent across code, tests, and cassette
All references in sample-app/tool_calling.go, sample-app/tool_calling_test.go, and sample-app/testdata/tool_calling_cassette.yaml use the exact name and schema “get_weather”, so no changes are needed.sample-app/README_testing.md (1)
19-23: .gitignore correctly configured for VCR cassettesThe
sample-app/.gitignorefile already ignores all files undertestdata/*and explicitly allows only the sanitized cassette:
- testdata/*
- !testdata/tool_calling_cassette.yaml
No further changes are needed.
traceloop-sdk/dto/tracing.go (1)
7-8: DTO additions look solidThe added
Tool*andToolCall*structs cleanly extend the model; JSON tags are consistent with OpenAI payloads.Also applies to: 10-30, 42-43

3. traceloop-sdk/tracing.go:19
- Draft comment:
Consider using the standard library's URL parsing (net/url) instead of manual string manipulation to sanitize and append a default port. This could handle edge cases (e.g., trailing slashes or malformed URLs) more robustly. - Reason this comment was not posted:
Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 30% vs. threshold = 50% The suggestion is reasonable since net/url is the standard way to handle URLs in Go and could handle edge cases better. However, the current implementation is simple and handles the basic cases needed. The code only needs to strip protocols and add a port - it's not doing complex URL parsing. The current approach is readable and maintainable for this specific use case. The current code might fail with URLs containing userinfo sections or URLs with multiple colons. The net/url package would handle these cases correctly. While net/url would be more robust, this code is specifically handling API endpoints which are unlikely to contain userinfo or complex URL structures. The current solution is sufficient for its limited purpose. While using net/url would be more robust, the current implementation is simple, readable, and sufficient for its specific use case. The comment, while technically correct, suggests unnecessary complexity.

6-9: Two different OpenAI SDKs inflate the buildBoth
github.com/openai/openai-goandgithub.com/sashabaranov/go-openaiare required. Unless the sample app truly needs both, keep a single SDK to cut binary size and avoid cognitive overhead.sample-app/tool_calling.go (2)
11-13: Inconsistent SDK usageImporting the new official
openai-goSDK here while the rest of the sample app usesgo-openaileads to two divergent APIs in one repo. Standardise on one SDK for maintainability.
192-199: Missing default for temperature unitIf
unitis empty,getWeatherprints a dangling degree symbol (72°). Either default to"F"/"fahrenheit"or surface a validation error before callinggetWeather.traceloop-sdk/sdk.go (3)
80-92: Consider truncation/redaction for message content to meet OTel limits and privacy.
contentmay be large and/or contain PII. Add truncation (e.g., to 4–8KB) and optional redaction hooks to avoid exceeding attribute limits and leaking sensitive data.
96-106: Guard function-specific fields by type and consider truncating arguments.For non-"function" tool calls,
name/argumentsmay be empty or irrelevant. Also, arguments can be large/PII.func setToolCallsAttribute(span apitrace.Span, messagePrefix string, toolCalls []ToolCall) { for i, toolCall := range toolCalls { toolCallPrefix := fmt.Sprintf("%s.tool_calls.%d", messagePrefix, i) - span.SetAttributes( - attribute.String(toolCallPrefix+".id", toolCall.ID), - attribute.String(toolCallPrefix+".type", toolCall.Type), - attribute.String(toolCallPrefix+".name", toolCall.Function.Name), - attribute.String(toolCallPrefix+".arguments", toolCall.Function.Arguments), - ) + span.SetAttributes( + attribute.String(toolCallPrefix+".id", toolCall.ID), + attribute.String(toolCallPrefix+".type", toolCall.Type), + ) + if toolCall.Type == "function" { + span.SetAttributes( + attribute.String(toolCallPrefix+".name", toolCall.Function.Name), + attribute.String(toolCallPrefix+".arguments", toolCall.Function.Arguments), // consider truncation/redaction + ) + } } }
110-131: Don’t print to stdout from SDK; use log.Printf (or return error) for marshal failures.Printing directly to stdout is noisy for library consumers.
- if err == nil { + if err == nil { span.SetAttributes( attribute.String(prefix+".parameters", string(parametersJSON)), ) } else { - fmt.Printf("Failed to marshal tool parameters for %s: %v\n", tool.Function.Name, err) + log.Printf("Failed to marshal tool parameters for %s: %v", tool.Function.Name, err) }sample-app/main.go (5)
56-64: Preallocate slice for prompt messagesMicro-optimization and clarity; avoids re-allocations as the length is known.
- // Convert to our format for logging - var promptMsgs []sdk.Message + // Convert to our format for logging + promptMsgs := make([]sdk.Message, 0, len(request.Messages)) for i, message := range request.Messages { promptMsgs = append(promptMsgs, sdk.Message{ Index: i, Content: message.Content, Role: message.Role, }) }
98-106: Preallocate slice for completion messagesMinor efficiency improvement.
- // Convert response to our format for logging - var completionMsgs []sdk.Message + // Convert response to our format for logging + completionMsgs := make([]sdk.Message, 0, len(resp.Choices)) for _, choice := range resp.Choices { completionMsgs = append(completionMsgs, sdk.Message{ Index: choice.Index, Content: choice.Message.Content, Role: choice.Message.Role, }) }
21-24: Prefer flag/subcommands over manual os.Args parsingUsing the flag package (or subcommands) provides usage help and safer arg parsing. Optional, since this is a sample.
Example:
cmd := flag.String("cmd", "", "command to run (tool-calling)") flag.Parse() if *cmd == "tool-calling" { runToolCallingExample() return }
31-35: Fail fast if required env vars are missingSurface clear errors early for a better developer experience.
func workflowExample() { ctx := context.Background() - traceloop, err := sdk.NewClient(ctx, sdk.Config{ + if os.Getenv("TRACELOOP_API_KEY") == "" { + log.Println("TRACELOOP_API_KEY is not set") + return + } + if os.Getenv("OPENAI_API_KEY") == "" { + log.Println("OPENAI_API_KEY is not set") + return + } + traceloop, err := sdk.NewClient(ctx, sdk.Config{ APIKey: os.Getenv("TRACELOOP_API_KEY"), })
37-38: Use log.Printf for errors for consistent loggingOptional style nit: use log.Printf instead of fmt.Printf for errors to include timestamps and standardize logs.

80-92: Ensure unique attribute prefixes to avoid collisionsWe couldn’t find any code that sets or enforces uniqueness of
Message.Indexin the repository. IfIndexisn’t guaranteed unique and sequential, using it for attribute names risks naming collisions at telemetry time.Please verify one of the following approaches:
- Use the loop index (
i) when buildingattrsPrefixto ensure no duplicates:for i, message := range messages { attrsPrefix := fmt.Sprintf("%s.%d", prefix, i) … }- Or document and enforce that every
Message.Indexis set uniquely and incrementally before callingsetMessagesAttribute.Key locations:

🛠️ Refactor suggestion
omitempty ineffective on value-type Function field
Because Tool.Function is a value (not a pointer), JSON encoding will emit an empty {} even when unset. If you intend the field to disappear entirely, make it *ToolFunction or use json:",omitempty" on a pointer.
🤖 Prompt for AI Agents
In traceloop-sdk/tracing_types.go around lines 45 to 48, the Tool.Function field
is a value type, so the `omitempty` tag does not prevent it from being
serialized as an empty object. To fix this, change the type of Function from
ToolFunction to a pointer *ToolFunction so that when it is nil, it will be
omitted from the JSON output as intended.

💡 Verification agent
🧩 Analysis chain
Prefer a go.work workspace over committing replace directives.
Local replaces are fine for development, but a go.work at the repo root is cleaner for multi-module repos and avoids leaking local paths in committed go.mod files.
Check if a workspace file exists:
If adopting go.work, you can remove these replace lines and add the modules via:
- go work init ./traceloop-sdk ./semconv-ai ./sample-app
🏁 Script executed:
#!/bin/bash
fd -a go.workLength of output: 73
To confirm that the workspace already includes the local modules (so we can safely drop those replace lines), let’s inspect the contents of your go.work:
🏁 Script executed:
#!/bin/bash
echo "=== go.work ==="
cat go.workLength of output: 112
Remove redundant replace directives in sample-app/go.mod
Since your go.work already includes sample-app, semconv-ai, and traceloop-sdk, you can drop the local replace lines to avoid leaking file paths into committed go.mod files.

- Draft comment:
Changing the event trigger from 'pull_request_target' to 'pull_request' alters the workflow's security context. Ensure this is intentional—if the build requires secrets (or elevated privileges), using 'pull_request' might restrict access for PRs from forks. - Reason this comment was not posted:
Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 10% vs. threshold = 50% The comment is technically correct about the security context difference between pull_request and pull_request_target. However, this workflow appears to be a basic CI pipeline that doesn't use any secrets or require special permissions. The change to pull_request is actually safer by default. The comment is asking for verification without clear evidence of a problem. I could be missing some hidden secrets or permissions that aren't visible in this file. There could be environment variables defined elsewhere. Even if there were hidden secrets, the change to pull_request is the safer option by default. If secrets were needed, the workflow would fail immediately, making it an obvious issue that doesn't need a comment. Delete this comment. It asks for verification without evidence of an actual problem, and the change appears to be an improvement in security posture.

In traceloop-sdk/simple_test.go lines 1 to 7, the current test only logs a
message without any assertions, making it ineffective as a test. Replace the
TestSimple function with an ExampleSimple function that demonstrates usage and
serves as a documentation test, or alternatively add real assertions to verify
expected behavior. This change will make the test meaningful and useful for both
testing and documentation purposes.

Comment did not seem useful. Confidence is useful =40%<= threshold50%The comment is asking the PR author to ensure that dropping older versions is intentional. This violates the rule against asking the author to confirm their intention. However, it does point out a specific change in the CI workflow that could be important to address, but the phrasing needs to be more about confirming the intention rather than ensuring it.
2. go.work:1
- Draft comment:
go.work: Changed Go version format to '1.23' and added new modules (semconv-ai, traceloop-sdk) to the workspace. Confirm that module paths and replacements correctly reflect project structure. - Reason this comment was not posted:
Comment did not seem useful. Confidence is useful =0%<= threshold50%The comment is asking the PR author to confirm that module paths and replacements correctly reflect the project structure.

Keep both only if intentionally demonstrating alternatives; otherwise, drop one to reduce bloat and confusion. If you keep both, call this out explicitly in the sample README.

9-10: Pseudo-version placeholder for traceloop-sdkv0.0.0-00010101000000-000000000000 is a placeholder and is ignored under go.work. If the sample is ever built outside the workspace, pin to a real version (tag or commit-derived pseudo-version).

3-4: Good move switching to pull_request; consider additional event types.Switching away from pull_request_target reduces risk. Consider including reopened (and optionally ready_for_review) to ensure CI runs on those updates too.
Example:
on: - pull_request: - types: [opened, synchronize] + pull_request: + types: [opened, synchronize, reopened]
14-14: Verify Go 1.24 availability; prefer patch-tracking specifiers.If 1.24 isn't GA or supported by setup-go yet, the matrix will fail. Prefer "1.22.x"/"1.23.x" to always pick latest patches.
- go-version: ["1.22", "1.23", "1.24"] + go-version: ["1.22.x", "1.23.x"]If 1.24 is confirmed available, use "1.24.x".
22-22: Optional: enable module cache for faster CI across matrix runs.cache: false is safe but slow. Consider enabling cache with a multi-module dependency path.
- cache: false + cache: true + cache-dependency-path: "**/go.sum"
26-26: Build all packages in each module.go build . only targets the current package; building ./... ensures all subpackages compile.

In .github/workflows/ci.yml at line 24, replace the command using 'go get .'
with 'go mod download' or 'go mod verify' to avoid modifying go.mod or go.sum
files during CI runs. This change prevents unintended mutations of module files
by ensuring dependencies are only downloaded or verified without altering the
module definitions.

1. go.mod:7
- Draft comment:
Consider documenting the reason for the new replace directive for the semconv-ai module. Local replacement (replace github.com/traceloop/go-openllmetry/semconv-ai => ./semconv-ai) is useful for development but should be clearly explained in the README to avoid confusion during dependency management. - Reason this comment was not posted:
Comment was not on a location in the diff, so it can't be submitted as a review comment.
2. go.work.sum:31
- Draft comment:
There is a version mismatch for the github.com/google/go-cmp dependency. The go.work.sum file lists v0.6.0 while semconv-ai/go.sum uses v0.7.0. Aligning these versions can prevent potential dependency resolution issues. - Reason this comment was not posted:
Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 0% vs. threshold = 50% According to the rules, we should NOT comment on dependency changes or library versions. The rules explicitly state to ignore dependency-related issues. While there is a real version mismatch, managing dependencies is outside the scope of what these comments should address. The version mismatch could potentially cause real issues in the build. Maybe this is important enough to be an exception to the dependency rule? No - the rules are very clear about not commenting on dependencies. If there are dependency issues, they will be caught by the build system or dependency management tools. Delete this comment as it violates the rule about not commenting on dependency changes or library versions.

Typo in the module path: "go-openllmetry" appears to be a misspelling. Did you mean "go-opentelemetry"? - Reason this comment was not posted:

1. sample-app/main.go:39
- Draft comment:
Removed fixed delay (time.Sleep) for prompt registry population. Ensure that the prompt registry is fully initialized before calling GetOpenAIChatCompletionRequest to avoid potential race conditions. - Reason this comment was not posted:
Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 20% vs. threshold = 50% The sleep was likely added as a hack/workaround. Without seeing the internals of the SDK, we can't know if removing it will cause issues. The SDK should handle its own initialization properly. The comment is speculative and asks for verification without providing concrete evidence of an issue. The sleep might have been added due to a real race condition that was discovered through testing. Removing it could reintroduce that issue. If there was a real race condition, it should be handled properly in the SDK itself, not with arbitrary sleeps in client code. The comment doesn't provide evidence of actual issues. Delete the comment as it's speculative and asks for verification without concrete evidence of an issue. If there are initialization problems, they should surface in testing.
