Note Other AI code review bot(s) detectedCodeRabbit has detected other AI code review bot(s) in this pull request and will avoid duplicating their findings in the review comments. This may lead to a less comprehensive review. WalkthroughAdds a new Associations API (types, set/merge behavior, span attribute mapping), fixes a context-key typo, exports the module, adds tests and HAR fixtures, updates span processing, introduces two sample chat apps and npm scripts, and adds an OpenTelemetry async-hooks dependency.

1. packages/traceloop-sdk/src/lib/node-server-sdk.ts:67
- Draft comment:
Exporting the associations module here cleanly exposes the Associations API. Ensure that its public API is well documented for users. - Reason this comment was not posted:
Confidence changes required:0%<= threshold50%None
2. packages/traceloop-sdk/src/lib/tracing/associations.ts:70
- Draft comment:
Accessing the private method _getContextManager via casting to 'any' is a bit hacky; consider using a public API for context management if available, or add a comment explaining why this approach is needed. - 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 suggests using a public API or adding a comment explaining why this approach is needed. However, there ARE already comments in the code (lines 68-69 and 75) explaining why this approach is taken. The comment on line 69 explicitly states this is replicating Python's attach behavior, and line 75 explains the need for internal access. The automated tool's suggestion to "add a comment explaining why this approach is needed" is already satisfied. The suggestion to "use a public API if available" is speculative - it assumes there might be a better way without providing evidence that one exists. This violates the rule about not making speculative comments. Perhaps the existing comments aren't detailed enough, and the reviewer's suggestion could prompt the author to add more explanation about why no public API exists for this use case. The comment might also encourage the author to research if there's a better approach they missed. The rules explicitly state not to ask the author to confirm, double-check, or ensure things. Suggesting they "consider using a public API if available" is essentially asking them to verify they chose the right approach. The code already has explanatory comments, so the suggestion to add comments is already addressed. This is speculative and not actionable. The comment should be deleted because: 1) It suggests adding explanatory comments, but comments already exist explaining the approach, 2) It speculatively suggests using a public API "if available" without evidence one exists, which violates the rule against speculative comments, and 3) It's essentially asking the author to verify their approach, which the rules prohibit.
3. packages/traceloop-sdk/src/lib/tracing/span-processor.ts:302
- Draft comment:
The use of a random condition (Math.random() < 0.01) for cleanup of span agent names may lead to unpredictable cleanup timing. Consider using a dedicated periodic cleanup or a more deterministic strategy. - 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.
4. packages/traceloop-sdk/src/lib/tracing/association.ts:17
- Draft comment:
The merging of associations using the context API is clear and concise. No issues detected, but ensure that edge cases (e.g. empty properties) are handled as expected. - Reason this comment was not posted:
Confidence changes required:0%<= threshold50%None
5. packages/traceloop-sdk/test/associations.test.ts:80
- Draft comment:
The tests comprehensively cover single and multiple associations, as well as updates and propagation across child spans. Ensure that test recordings remain in sync with the current implementation. - Reason this comment was not posted:
Confidence changes required:0%<= threshold50%None
6. packages/traceloop-sdk/src/lib/tracing/association.ts:20
- Draft comment:
Typo: Consider correcting 'ASSOCATION_PROPERTIES_KEY' to 'ASSOCIATION_PROPERTIES_KEY'. - 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 typo exists in the constant name 'ASSOCATION_PROPERTIES_KEY', but this constant is imported from another file (line 2:import { ASSOCATION_PROPERTIES_KEY } from "./tracing";). The diff shows that the code on lines 20 and 27 uses this constant, and line 20 is part of the new code added in this PR. However, to fix this typo, the constant would need to be renamed in the file where it's defined ("./tracing"), not in this file. The comment is placed on line 20, which is new code in the diff, so it is technically about changes. But the fix would require changes in another file (the import source), not just this file. According to the rules, I should "Ignore cross-file issues. Only think about the file you are reviewing." While the typo is real and the line is part of the diff, fixing it would require changing the constant definition in another file and updating the import, making this a cross-file issue. However, one could argue that the comment is still useful as it identifies a legitimate issue that should be addressed, even if it spans multiple files. The rules explicitly state to "Ignore cross-file issues. Only think about the file you are reviewing." Since fixing this typo would require changes to the constant definition in "./tracing" file and potentially other files that use it, this is clearly a cross-file issue and should be deleted according to the guidelines. This comment should be deleted because fixing the typo would require changes across multiple files (the constant definition in "./tracing" and all its usages), making it a cross-file issue which the rules explicitly say to ignore.

1-490: Valid HAR recording for Polly.js test replay.The file is a well-formed HAR 1.2 recording that captures the mid-workflow associations update scenario: two sequential OpenAI chat completions requests demonstrating association changes between calls. The structure, metadata (startedDateTime, timings), base64-encoded responses, and Polly.js naming conventions are all correct.
packages/sample-app/package.json (1)
18-18: LGTM!The new demo scripts follow the established pattern and provide convenient entry points for showcasing the associations API and interactive chatbot functionality.
Also applies to: 47-47
packages/traceloop-sdk/src/lib/node-server-sdk.ts (1)
67-67: LGTM!The export follows the established pattern and correctly exposes the new associations API as part of the SDK's public surface.
packages/traceloop-sdk/src/lib/tracing/span-processor.ts (2)
18-18: LGTM!The import correctly brings in the standard association properties set for distinguishing standard from custom properties.
204-213: LGTM!The conditional logic correctly distinguishes between standard and custom association properties. Standard properties (conversation_id, customer_id, user_id, session_id) are set directly on spans for better discoverability, while custom properties retain the namespace prefix to avoid conflicts.
packages/traceloop-sdk/src/lib/tracing/association.ts (1)
17-27: LGTM! Note the merge semantics.The new merging logic correctly accumulates association properties across nested calls. The spread operator semantics mean that new properties override existing ones with the same key, which appears intentional for allowing updates to associations mid-workflow.
packages/traceloop-sdk/package.json (1)
60-60: The@opentelemetry/context-async-hooksdependency is used in the codebase. It is imported to instantiate AsyncLocalStorageContextManager for context propagation in packages/traceloop-sdk/src/lib/tracing/associations.ts.packages/traceloop-sdk/recordings/Test-Associations-API_2277442331/should-propagate-associations-to-all-child-spans_3781439892/recording.har (1)
1-252: LGTM!This HAR recording follows the expected Polly.js format and is correctly placed under the
recordings/directory as per coding guidelines. Authorization headers are properly filtered out.packages/traceloop-sdk/recordings/Test-Associations-API_2277442331/should-merge-associations-from-Associations-set-and-withAssociationProperties_2272111199/recording.har (1)
1-252: LGTM!This HAR recording is properly structured for the merge associations test case, with authorization headers correctly filtered.
packages/traceloop-sdk/test/associations.test.ts (3)
17-36: LGTM!Good use of
SpanAttributesfrom@traceloop/ai-semantic-conventionsas per coding guidelines. The shared test setup approach prevents conflicts with other test suites.
40-82: LGTM!The test setup properly handles recording vs replay modes, filters authorization headers from recordings to prevent secrets leakage, and resets the memory exporter between tests for isolation.
84-367: LGTM!Comprehensive test coverage for the Associations API including:
- Single and multiple association setting
- Mid-workflow updates
- All property types
- Child span propagation
- Merging standard associations with custom properties via
withAssociationPropertiesThe tests correctly verify that standard properties appear without prefix while custom properties use the
TRACELOOP_ASSOCIATION_PROPERTIESprefix.packages/traceloop-sdk/src/lib/tracing/associations.ts (2)
5-26: LGTM!Clean API design with the
AssociationPropertyenum providing type safety, andSTANDARD_ASSOCIATION_PROPERTIESenabling O(1) lookup for distinguishing standard from custom properties.
82-88: LGTM!Correctly sets standard association properties directly on the span without a prefix, with a proper
isRecording()guard.packages/sample-app/src/sample_associations.ts (4)
1-12: LGTM!Clean initialization with the Traceloop SDK and OpenAI client. Using environment variable for the API key is a good practice.
18-87: LGTM!Good demonstration of the Associations API using the
@workflowand@taskdecorators as per coding guidelines. The combination ofAssociations.set()for standard properties andwithAssociationProperties()for custom properties is clearly illustrated.
89-141: LGTM!Good demonstration of updating associations mid-workflow to track different customers and agents within the same workflow context.
143-178: LGTM!Clean main function with proper error handling and helpful console output guiding users to check the Traceloop dashboard.
packages/sample-app/src/sample_chatbot_interactive.ts (5)
1-25: LGTM!Clean imports and initialization. Using Zod for tool parameter validation is a good practice.
38-41: Acceptable for demo purposes.Using
Date.now()andMath.random()for generating demo conversation/user IDs is fine for a sample application. These are not used in any security-sensitive context—they're purely for tracing identification in a demo scenario.
43-77: LGTM!Good use of the
@taskdecorator as per coding guidelines. The streaming summary generation with GPT-4o-mini is appropriate for creating brief interaction titles.
218-276: LGTM!Clean implementation of the interactive CLI with proper command handling (
/exit,/clear), error handling around message processing, and cleanup on close.
279-284: LGTM!Clean main entry point with error handling.

67-79: Private OpenTelemetry API access requires documentation and fallback handling.This issue was already flagged in a previous review. The code accesses undocumented internal APIs (
_getContextManager()and_asyncLocalStorage) which may break across OpenTelemetry versions. Additionally, if the context manager is notAsyncLocalStorageContextManager, associations silently fail to propagate.Consider adding:
- A comment documenting this as a Node.js-only workaround
- Warning-level logging when the expected context manager is not found
- Documentation of minimum OpenTelemetry version requirements

8-12: MissingCONVERSATION_IDfrom the enum.The PR objectives mention support for
CONVERSATION_ID, but theAssociationPropertyenum only includesCUSTOMER_ID,USER_ID, andSESSION_ID. If this is intentional, please update the PR description; otherwise, add the missing property.🔎 Proposed fix to add CONVERSATION_ID
export enum AssociationProperty { + CONVERSATION_ID = "conversation_id", CUSTOMER_ID = "customer_id", USER_ID = "user_id", SESSION_ID = "session_id", }
46-88: Implementation correctly merges and propagates associations.The logic for retrieving existing associations, merging new values, updating the context, and setting span attributes is well-structured. The use of spread operator for immutable copy is appropriate.

43-77: Good use of Traceloop decorators and Associations API.The implementation correctly uses
@traceloop.workflowand@traceloop.taskdecorators as per the SDK guidelines, and properly demonstrates the newAssociations.set()API withAssociationPropertyenum values.Also applies to: 79-86
225-276: Solid interactive CLI implementation with proper cleanup.The readline handling includes appropriate command processing (
/exit,/clear), error handling for message processing, and graceful shutdown on close events.

Replace eval() with a safe math expression parser.
Even with character sanitization, eval() poses security risks and is flagged by static analysis. The regex sanitization allows operators that could still be exploited or cause unexpected behavior (e.g., empty expressions, division by zero edge cases).
Consider using a library like mathjs or expr-eval for safe expression evaluation.
🔎 Proposed fix using expr-eval
First, add the dependency:
npm install expr-evalThen update the code:
+import { Parser } from "expr-eval";
+
+const mathParser = new Parser();
+
calculator: tool({
description:
"Perform mathematical calculations. Supports basic arithmetic operations.",
parameters: z.object({
expression: z
.string()
.describe(
"The mathematical expression to evaluate (e.g., '2 + 2' or '10 * 5')",
),
}),
execute: async ({ expression }) => {
try {
- // Simple safe eval for basic math (only allow numbers and operators)
- const sanitized = expression.replace(/[^0-9+\-*/().\s]/g, "");
- const result = eval(sanitized);
+ const result = mathParser.evaluate(expression);
console.log(
`\n${colors.yellow}🔧 Calculator: ${expression} = ${result}${colors.reset}`,
);
return { result, expression };
} catch (error) {
return { error: "Invalid mathematical expression" };
}
},

In packages/sample-app/src/sample_chatbot_interactive.ts around lines 117-129,
replace the unsafe eval-based math evaluation with a safe expression parser
(e.g., expr-eval): add the dependency (npm install expr-eval), import Parser
from 'expr-eval', validate the incoming expression is non-empty, parse and
evaluate using Parser.parse(expression).evaluate(), catch parse/eval errors and
return a clear "Invalid mathematical expression" error, and handle edge cases
like division by zero by detecting Infinity/NaN results and returning an error
instead of logging them; keep the same console output format when returning a
valid result.
