[DRAFT] APM AI Toolkit: Add Feign HTTP client instrumentation (v8.0+) 2nd run with add-apm-integrations.md by jordan-wong · Pull Request #10855 · DataDog/dd-trace-java

jordan-wong · 2026-03-16T14:10:09Z

2nd Iteration testing out new skill add-apm-integrations

Generated complete instrumentation for Feign HTTP client library using apm-instrumentation-toolkit with add-apm-integrations skill.

Implementation:

FeignInstrumentation.java: Main instrumentation targeting feign.Client.execute()
FeignClientDecorator.java: HTTP client decorator with span lifecycle management
RequestInjectAdapter.java: Header injection adapter for distributed tracing
FeignTest.groovy: Comprehensive test suite extending HttpClientTest

Key features:

Instruments Feign 8.0+ (version range [8.0,9.0))
Uses classLoaderMatcher to distinguish from pre-8.0 versions
Direct header injection into mutable headers map
Proper span lifecycle: startSpan → prepareSpan → injectHeaders → activateSpan
All verification passed: compilation, spotless, tests, muzzle, latestDepTest

Test results: 100% pass rate
Generated by: apm-instrumentation-toolkit
