Align the heartbeat transport contract. The default configuration targets port 3000, while the registry defaults to port 4000, and the configured heartbeat route has no registry handler.

Expose context-aware tracing through @clevercon/common.
The package exports only src/index.ts, which does not re-export startSpan, extractTraceContext, or runInSpan. Export a context-aware tracing API so inbound agent requests can preserve the remote W3C parent span.

Read propagation headers without case sensitivity.
The getter only reads an exact key. A carrier with Traceparent or TRACESTATE returns no value, so extraction drops the valid remote parent and starts a separate trace.
W3C Trace Context requires receivers to accept traceparent and tracestate in any case. OpenTelemetry also requires HTTP getters to be case-insensitive. (w3.org)
Proposed fix

- const value = carrier[key];
+ const entry = Object.entries(carrier).find(
+ ([headerName]) => headerName.toLowerCase() === key.toLowerCase(),
+ );
+ const value = entry?.[1];
if (Array.isArray(value)) {
return value[0];
}
- return value as string | undefined;

OpenTelemetry JavaScript sdk-trace-node BatchSpanProcessor SimpleSpanProcessor export behavior OTLP exporter documentation
💡 Result:
In the OpenTelemetry JavaScript SDK, span processors manage how spans are handled after they are created [1][2]. The two primary implementations, BatchSpanProcessor and SimpleSpanProcessor, have distinct export behaviors that significantly impact application performance [1][3]. BatchSpanProcessor The BatchSpanProcessor collects spans in a buffer and exports them in batches [1][4]. This is the recommended processor for production environments because it minimizes the number of outgoing network requests, reducing overhead [1][3]. It includes configurable settings such as maxQueueSize (the maximum number of spans held in memory), maxExportBatchSize (the maximum number of spans per export request), and scheduledDelayMillis (the interval between exports) [5][6]. SimpleSpanProcessor The SimpleSpanProcessor processes and exports each span immediately upon completion [1][3]. Because it initiates an export operation for every single span, it is unsuitable for most production workloads due to the significant performance overhead it introduces [3]. It is generally reserved for development, debugging, or specific scenarios where immediate export is required and latency impact is acceptable [1][2]. OTLP Exporter Behavior When using the OTLP exporter, the choice of processor determines how your traces are delivered [5]. - Default Behavior: If you use the NodeSDK without explicitly defining a span processor, it automatically defaults to using a BatchSpanProcessor with an OTLP exporter [7][8]. - Programmatic Configuration: If you configure an exporter (e.g., OTLPTraceExporter) directly in your tracer provider, you must associate it with a processor [9]. Using the spanProcessors configuration array in the NodeSDK is the standard way to register your processor(s) [7][9]. - Conflict Note: It is important to note that if you provide a custom traceExporter in the NodeSDK configuration, the SDK may prioritize or wrap that exporter in a BatchSpanProcessor [7][8]. If you define custom spanProcessors, they typically take precedence [10][7]. For most use cases, you should explicitly configure the BatchSpanProcessor with your OTLP exporter to ensure optimal performance [1][5].

Use BatchSpanProcessor for OTLP exports.
When config.exporter is 'otlp', use BatchSpanProcessor. Keep SimpleSpanProcessor for console output. This prevents one failed export request per ended span when the collector is unavailable.

OpenTelemetry JavaScript API NoopTracer startActiveSpan NonRecordingSpan INVALID_SPAN_CONTEXT isSpanContextValid official source
💡 Result:
In the OpenTelemetry JavaScript API, the components you referenced interact to handle tracing context, often in scenarios where no actual recording or backend export is required [1][2]. Key Concepts: INVALID_SPAN_CONTEXT: This is a constant representing an invalid SpanContext, defined with an empty trace ID (00000000000000000000000000000000) and an empty span ID (0000000000000000) [3][4]. It is used as a placeholder when no valid span context is available or required [5]. isSpanContextValid: This is a utility function that validates a SpanContext by checking if its trace ID and span ID are non-zero and follow the required hex format [6][7][8]. It returns true only if both IDs are valid [7]. NoopTracer: This is the default implementation of the Tracer interface when no SDK is installed [1][2]. When its startSpan method is called, it checks the context for an existing parent [1]. If a valid parent span context is found (determined using isSpanContextValid), it may wrap that context in a NonRecordingSpan; otherwise, it creates a new NonRecordingSpan with no context [1]. NonRecordingSpan: This is a span implementation that does not record telemetry data (i.e., it does not perform any operations when methods like setAttribute or end are called) [1][6]. It is frequently used by the NoopTracer or when creating spans that should not be exported [5]. The OpenTelemetry documentation recommends using api.trace.wrapSpanContext with INVALID_SPAN_CONTEXT if you need to create a no-op span, rather than relying directly on the NoopTracer class, which is not exported for direct use in all versions [2][9]. This pattern ensures that the span behaves as a non-recording entity while maintaining consistency with the OpenTelemetry specification [5][6].

Guard invalid span contexts before returning trace identifiers.
When tracing is disabled, tracer.startActiveSpan can activate a NonRecordingSpan with INVALID_SPAN_CONTEXT. Its zero-filled identifiers pass the logger’s truthiness check. If trace.isSpanContextValid(spanContext) is false, return undefined from both tracer helpers and {} from getTraceContext().

Keep loadAgents coherent with saveAgents.
saveAgents updates cache before its queued disk write completes. This implementation always reloads the file, so a read before the queue drains can return stale state and a later update can overwrite the cached change. Use cache when it exists, and initialize it after a successful disk read before applying TTL transitions.

Summary
Closes #109
This PR introduces distributed tracing across the CleverCon task execution pipeline using OpenTelemetry.
A single task can now be followed end-to-end across planning, concurrent step execution, specialist agent calls over x402/MPP, and vault/Soroban interactions. Trace context is propagated across agent HTTP boundaries using W3C
traceparent, while existing structured logs are enriched with OpenTelemetrytraceIdandspanIdfor easier correlation and debugging.Tracing is designed to be non-invasive: it is disabled by default, requires no collector for local development or tests, and can be disabled without changing existing application behavior.
