Unfortunately those features are\n 365\u2192not available in Advice code during development of a Java agent. You\u2019ll need to add `println()` statements and rebuild\n 366\u2192the tracer JAR to test/debug in a traced client application. `println()` is used instead of log statements because the\n 367\u2192logger may not be initialized yet. Debugging should work as usual in helper methods that are called from advice code.\n 368\u2192\n 369\u2192By default, advice code is inlined into instrumented code. In that case breakpoints can not be set in the advice code.\n 370\u2192But when a method is annotated like this:\n 371\u2192\n 372\u2192`@Advice.OnMethodExit(inline = false)`\n 373\u2192\n 374\u2192or\n 375\u2192\n 376\u2192`@Advice.OnMethodEnter(inline = false)`\n 377\u2192\n 378\u2192the advice bytecode is not copied and the advice is invoked like a common Java method call, making it work like a helper\n 379\u2192class. Debugging information is copied from the advice method into the instrumented method and debugging is possible.\n 380\u2192\n 381\u2192It is not possible to use `inline=false` for all advice code. For example, when modifying argument\n 382\u2192values, `@Argument(value = 0, readOnly = false)` is impossible since the advice is now a regular method invocation which\n 383\u2192cannot be modified.\n 384\u2192\n 385\u2192It is important to remove `inline=false` after debugging is finished for performance reasons.\n 386\u2192\n 387\u2192(\n 388\u2192see [inline](https://javadoc.io/static/net.bytebuddy/byte-buddy/1.14.10/net/bytebuddy/asm/Advice.OnMethodExit.html#inline--))\n 389\u2192\n 390\u2192## Building\n 391\u2192\n 392\u2192Configure your environment as discussed\n 393\u2192in [CONTRIBUTING.md](../CONTRIBUTING.md).

= \"rediscala_2.11\"\n 69\u2192 versions = \"[1.5.0,)\"\n 70\u2192 assertInverse = true\n 71\u2192 }\n 72\u2192\n 73\u2192 pass {\n 74\u2192 group = \"com.github.etaty\"\n 75\u2192 module = \"rediscala_2.12\"\n 76\u2192 versions = \"[1.8.0,)\"\n 77\u2192 assertInverse = true\n 78\u2192 }\n 79\u2192}\n 80\u2192```\n 81\u2192\n 82\u2192This means that the instrumentation should be safe with `rediscala_2.11` from version `1.5.0` and all later versions,\n 83\u2192but should fail (and so will not be loaded), for older versions (see `assertInverse`).\n 84\u2192A similar range of versions is specified for `rediscala_2.12`.\n 85\u2192When the agent is built, the muzzle plugin will download versions of the framework and check these directives hold.\n 86\u2192To run muzzle on your instrumentation, run:\n 87\u2192\n 88\u2192```shell\n 89\u2192./gradlew :dd-java-agent:instrumentation:rediscala-1.8:muzzle\n 90\u2192```\n 91\u2192\n 92\u2192> [!WARNING]\n 93\u2192> Muzzle does _not_ run tests.\n 94\u2192> It checks that the types and methods used by the instrumentation are present in particular versions of libraries.\n 95\u2192> It can be subverted with `MethodHandle` and reflection -- in other words, having the `muzzle` task passing is not enough\n 96\u2192> to validate an instrumentation.\n 97\u2192\n 98\u2192By default, all the muzzle directives are checked against all the instrumentations included in a module.\n 99\u2192However, there can be situations in which it's only needed to check one specific directive on an instrumentation.\n 100\u2192At this point the instrumentation should override the method `muzzleDirective()` by returning the name of the directive to execute.\n 101\u2192\n 102\u2192### Identifying Breaking Changes with JApiCmp\n 103\u2192\n 104\u2192Before defining muzzle version ranges, you can use the JApiCmp plugin to compare different versions of a library and\n 105\u2192identify breaking API changes. This helps determine where to split version ranges in your muzzle directives.\n 106\u2192\n 107\u2192The `japicmp` task compares two versions of a Maven artifact and reports:\n 108\u2192- Removed classes and methods (breaking changes)\n 109\u2192- Added classes and methods (non-breaking changes)\n 110\u2192- Modified methods with binary compatibility status\n 111\u2192\n 112\u2192#### Usage\n 113\u2192\n 114\u2192Compare two versions of any Maven artifact:\n 115\u2192\n 116\u2192```shell\n 117\u2192./gradlew japicmp -Partifact=groupId:artifactId -Pbaseline=oldVersion -Ptarget=newVersion\n 118\u2192```\n 119\u2192\n 120\u2192For example, to compare MongoDB driver versions:\n 121\u2192\n 122\u2192```shell\n 123\u2192./gradlew japicmp -Partifact=org.mongodb:mongodb-driver-sync -Pbaseline=3.11.0 -Ptarget=4.0.0\n 124\u2192```\n 125\u2192\n 126\u2192#### Output\n 127\u2192\n 128\u2192The task generates two reports:\n 129\u2192\n 130\u2192- **Text report**: `build/reports/japicmp.txt` - Detailed line-by-line comparison\n 131\u2192- **HTML report**: `build/reports/japicmp.html` - Browsable visual report\n 132\u2192\n 133\u2192## Instrumentation classes\n 134\u2192\n 135\u2192The Instrumentation class is where the instrumentation begins.

class names should end in _Decorator._\n 390\u2192\n 391\u2192## Advice Classes\n 392\u2192\n 393\u2192Byte Buddy injects compiled bytecode at runtime to wrap existing methods, so they communicate with Datadog at entry or exit.\n 394\u2192These modifications are referred to as _advice transformation_ or just _advice_.\n 395\u2192\n 396\u2192Instrumenters register advice transformations by calling `AdviceTransformation.applyAdvice(ElementMatcher, String)` \n 397\u2192and Methods are matched by the instrumentation's `adviceTransformations()` method.\n 398\u2192\n 399\u2192The Advice is injected into the type so Advice can only refer to those classes on the bootstrap class-path or helpers\n 400\u2192injected into the application class-loader.\n 401\u2192Advice must not refer to any methods in the instrumentation class or even other methods in the same advice class because\n 402\u2192the advice is really only a template of bytecode to be inserted into the target class.\n 403\u2192It is only the advice bytecode (plus helpers) that is copied over.\n 404\u2192The rest of the instrumenter and advice class is ignored.\n 405\u2192Do not place code in the Advice constructor because the constructor is never called.\n 406\u2192\n 407\u2192You can not use methods like `InstrumentationContext.get()` outside of the instrumentation advice because the tracer\n 408\u2192currently patches the method stub with the real call at runtime.\n 409\u2192But you can pass the ContextStore into a helper/decorator like in [DatadogMessageListener](https://github.com/DataDog/dd-trace-java/blob/743bacde52ba4369e05631436168bfde9b815c8b/dd-java-agent/instrumentation/jms/src/main/java/datadog/trace/instrumentation/jms/DatadogMessageListener.java).\n 410\u2192This could reduce duplication if you re-used the helper.\n 411\u2192But unlike most applications, some duplication can be the better choice in the tracer if it simplifies things and reduces overhead.\n 412\u2192You might end up with very similar code scattered around, but it will be simple to maintain.\n 413\u2192Trying to find an abstraction that works well across instrumentations can take time and may introduce extra indirection.\n 414\u2192\n 415\u2192Advice classes provide the code to be executed before and/or after a matched method.\n 416\u2192The classes use a static method annotated by `@Advice.OnMethodEnter` and/or `@Advice.OnMethodExit` to provide the code.\n 417\u2192The method name is irrelevant.\n 418\u2192\n 419\u2192A method that is annotated with `@Advice.OnMethodEnter `can annotate its parameters with `@Advice.Argument`.\n 420\u2192`@Advice.Argument` will substitute this parameter with the corresponding argument of the instrumented method.\n 421\u2192This allows the `@Advice.OnMethodEnter` code to see and modify the parameters that would be passed to the target method.\n 422\u2192\n 423\u2192Alternatively, a parameter can be annotated by `Advice.This` where the `this` reference of the instrumented method is\n 424\u2192assigned to the new parameter.\n 425\u2192This can also be used to assign a new value to the `this` reference of an instrumented method.\n 426\u2192\n 427\u2192If no annotation is used on a parameter, it is assigned the n-th parameter of the instrumented method for the n-th\n 428\u2192parameter of the advice method.\n 429\u2192Explicitly specifying which parameter is intended is recommended to be more clear, for example:\n 430\u2192\n 431\u2192`@Advice.Argument(0) final HttpUriRequest request`\n 432\u2192\n 433\u2192All parameters must declare the exact same type as the parameters of the instrumented type or the method's declaring\n 434\u2192type for `Advice.This`.\n 435\u2192If they are marked as read-only, then the parameter type may be a super type of the original.\n 436\u2192\n 437\u2192A method that is annotated with `Advice.OnMethodExit` can also annotate its parameters with `Advice.Argument`\n 438\u2192and `Advice.This`.\n 439\u2192It can also annotate a parameter with `Advice.Return` to receive the original method's return value.\n 440\u2192By reassigning the return value, it can replace the returned value.\n 441\u2192If an instrumented method does not return a value, this annotation must not be used.\n 442\u2192If a method throws an exception, the parameter is set to its default value (0 for primitive types and null for reference types).\n 443\u2192The parameter's type must equal the instrumented method's return type if it is not set to read-only.\n 444\u2192If the parameter is read-only it may be a super type of the instrumented method's return type.\n 445\u2192\n 446\u2192Advice class names should end in _Advice._\n 447\u2192\n 448\u2192### @AppliesOn Annotation\n 449\u2192\n 450\u2192The `@AppliesOn` annotation allows you to override which target systems a specific advice class applies to, independent of the InstrumenterModule's target system. This is useful when you have an instrumentation module that extends one target system (e.g., `InstrumenterModule.Tracing`), but want certain advice classes to also be applied for other target systems.\n 451\u2192\n 452\u2192#### Usage\n 453\u2192\n 454\u2192Annotate your advice class with `@AppliesOn` and specify the target systems where this advice should be applied:\n 455\u2192\n 456\u2192```java\n 457\u2192import datadog.trace.agent.tooling.InstrumenterModule.TargetSystem;\n 458\u2192import datadog.trace.agent.tooling.annotation.AppliesOn;\n 459\u2192\n 460\u2192@AppliesOn(TargetSystem.CONTEXT_TRACKING)\n 461\u2192public static class ContextTrackingAdvice {\n 462\u2192 @Advice.OnMethodEnter(suppress = Throwable.class)\n 463\u2192 public static void extractParent(\n 464\u2192 @Advice.Argument(0) org.apache.coyote.Request req,\n 465\u2192 @Advice.Local(\"parentScope\") ContextScope parentScope) {\n 466\u2192 // This advice only runs when CONTEXT_TRACKING is enabled\n 467\u2192 final Context parentContext = DECORATE.extract(req);\n 468\u2192 parentScope = parentContext.attach();\n 469\u2192 }\n 470\u2192\n 471\u2192 @Advice.OnMethodExit(suppress = Throwable.class, onThrowable = Throwable.class)\n 472\u2192 public static void closeScope(@Advice.Local(\"parentScope\") ContextScope scope) {\n 473\u2192 scope.close();\n 474\u2192 }\n 475\u2192}\n 476\u2192```\n 477\u2192\n 478\u2192#### When to Use @AppliesOn\n 479\u2192\n 480\u2192Use `@AppliesOn` when:\n 481\u2192\n 482\u21921. **Selective Advice Application**: You want different advice classes within the same instrumentation to apply to different target systems. For example, an instrumentation might extend `InstrumenterModule.Tracing` but have some advice that should only run for `CONTEXT_TRACKING`.\n 483\u2192\n 484\u21922. **Multi-System Support**: Your instrumentation needs to work across multiple target systems with different behaviors for each. By applying multiple advices with different `@AppliesOn` annotations, you can customize behavior per target system.\n 485\u2192\n 486\u21923. **Separating Concerns**: You want to cleanly separate context tracking logic from tracing logic in the same instrumentation, making the code more maintainable.\n 487\u2192\n 488\u2192#### Example: Tomcat Server Instrumentation\n 489\u2192\n 490\u2192In the Tomcat instrumentation, we apply both context tracking and tracing advices to the same method:\n 491\u2192\n 492\u2192```java\n 493\u2192@Override\n 494\u2192public void adviceTransformations(AdviceTransformation transformation) {\n 495\u2192 transformation.applyAdvices(\n 496\u2192 named(\"service\")\n 497\u2192 .and(takesArgument(0, named(\"org.apache.coyote.Request\")))\n 498\u2192 .and(takesArgument(1, named(\"org.apache.coyote.Response\"))),\n 499\u2192 TomcatServerInstrumentation.class.getName() + \"$ContextTrackingAdvice\",\n 500\u2192 TomcatServerInstrumentation.class.getName() + \"$ServiceAdvice\"\n 501\u2192 );\n 502\u2192}\n 503\u2192```\n 504\u2192\n 505\u2192The `ContextTrackingAdvice` is annotated with `@AppliesOn(TargetSystem.CONTEXT_TRACKING)`, so it only runs when context tracking is enabled. The `ServiceAdvice` (without the annotation) runs when the module's target system (`TRACING`) is enabled.\n 506\u2192\n 507\u2192#### Important Notes\n 508\u2192\n 509\u2192- If an advice class does not have the `@AppliesOn` annotation, it will be applied whenever the parent InstrumenterModule's target system is enabled.\n 510\u2192- When multiple advices are applied to the same method, they are applied in the order specified, and each one's target system compatibility is checked individually.\n 511\u2192\n 512\u2192## Exceptions in Advice\n 513\u2192\n 514\u2192Advice methods are typically annotated like\n 515\u2192\n 516\u2192`@Advice.OnMethodEnter(suppress = Throwable.class)`\n 517\u2192\n 518\u2192and\n 519\u2192\n 520\u2192`@Advice.OnMethodExit(onThrowable = Throwable.class, suppress = Throwable.class)`\n 521\u2192\n 522\u2192Using `suppress = Throwable.class` is considered our default for both methods unless there is a reason not to suppress.\n 523\u2192It means the exception handler is triggered on any exception thrown within the Advice, which terminates the Advice method.\n 524\u2192The opposite would be either no `suppress` annotation or equivalently `suppress = NoExceptionHandler.class` which would \n 525\u2192allow exceptions in Advice code to surface and is usually undesirable.\n 526\u2192\n 527\u2192> [!NOTE]\n 528\u2192> Don't use `suppress` on an advice hooking a constructor.\n 529\u2192> For older JVMs that do not support [flexible constructor bodies](https://openjdk.org/jeps/513), you can't decorate the\n 530\u2192> mandatory self or parent constructor call with try/catch, as it must be the first call from the constructor body.\n 531\u2192\n 532\u2192If\n 533\u2192the [`Advice.OnMethodEnter`](https://javadoc.io/static/net.bytebuddy/byte-buddy/1.10.2/net/bytebuddy/asm/Advice.OnMethodEnter.html)\n 534\u2192method throws an exception,\n 535\u2192the [`Advice.OnMethodExit`](https://javadoc.io/static/net.bytebuddy/byte-buddy/1.10.2/net/bytebuddy/asm/Advice.OnMethodExit.html)\n 536\u2192method is not invoked.\n 537\u2192\n 538\u2192The [`Advice.Thrown`](https://javadoc.io/static/net.bytebuddy/byte-buddy/1.10.2/net/bytebuddy/asm/Advice.Thrown.html)\n 539\u2192annotation passes any thrown exception from the instrumented method to\n 540\u2192the [`Advice.OnMethodExit`](https://javadoc.io/static/net.bytebuddy/byte-buddy/1.10.2/net/bytebuddy/asm/Advice.OnMethodExit.html)\n 541\u2192advice\n 542\u2192method. \n 543\u2192[`Advice.Thrown`](https://javadoc.io/static/net.bytebuddy/byte-buddy/1.10.2/net/bytebuddy/asm/Advice.Thrown.html) ****\n 544\u2192should annotate at most one parameter on the exit advice.\n 545\u2192\n 546\u2192If the instrumented method throws an exception,\n 547\u2192the [Advice.OnMethodExit](https://javadoc.io/static/net.bytebuddy/byte-buddy/1.10.2/net/bytebuddy/asm/Advice.OnMethodExit.html)\n 548\u2192method is still invoked unless\n 549\u2192the [Advice.OnMethodExit.onThrowable()](https://javadoc.io/static/net.bytebuddy/byte-buddy/1.10.2/net/bytebuddy/asm/Advice.OnMethodExit.html#onThrowable--)\n 550\u2192property is set to false.

[`docs/how_instrumentations_work.md`](docs/how_instrumentations_work.md) — full reference (types, methods, advice, helpers, context stores, decorators) -2. [`docs/add_new_instrumentation.md`](docs/add_new_instrumentation.md) — step-by-step walkthrough -3. [`docs/how_to_test.md`](docs/how_to_test.md) — test types and how to run them - -These files are the single source of truth. Reference them while implementing. - -**After reading the docs, sync this skill with them:** - -Compare the content of the three docs against the rules encoded in Steps 2–11 of this skill file. Look for: -- Patterns, APIs, or conventions described in the docs but absent or incorrect here -- Steps that are out of date relative to the current docs (e.g. renamed methods, new base classes) -- Advice constraints or test requirements that have changed - -For every discrepancy found, edit this file (`.claude/skills/apm-integrations/SKILL.md`) to correct it using the -`Edit` tool before continuing. Keep changes targeted: fix what diverged, add what is missing, remove what is wrong. -Do not touch content that already matches the docs. - -## Step 2 – Clarify the task - -If the user has not already provided all of the following, ask before proceeding: - -- **Framework name** and **minimum supported version** (e.g. `okhttp-3.0`) -- **Target class(es) and method(s)** to instrument (fully qualified class names preferred) -- **Target system**: one of `Tracing`, `Profiling`, `AppSec`, `Iast`, `CiVisibility`, `Usm`, `ContextTracking` -- **Whether this is a bootstrap instrumentation** (affects allowed imports) - -## Step 3 – Find a reference instrumentation - -Search `dd-java-agent/instrumentation/` for a structurally similar integration: -- Same target system -- Comparable type-matching strategy (single type, hierarchy, known types) - -Read the reference integration's `InstrumenterModule`, Advice, Decorator, and test files to understand the established -pattern before writing new code. Use it as a template. - -## Step 4 – Set up the module - -1. Create directory: `dd-java-agent/instrumentation/$framework/$framework-$minVersion/` -2. Under it, create the standard Maven source layout: - - `src/main/java/` — instrumentation code - - `src/test/groovy/` — Spock tests -3. Create `build.gradle` with: - - `compileOnly` dependencies for the target framework - - `testImplementation` dependencies for tests - - `muzzle { pass { } }` directives (see Step 9) -4. Register the new module in `settings.gradle.kts` in **alphabetical order** - -## Step 5 – Write the InstrumenterModule - -Conventions to enforce: - -- Add `@AutoService(InstrumenterModule.class)` annotation — required for auto-discovery -- Extend the correct `InstrumenterModule.*` subclass (never the bare abstract class) -- Implement the **narrowest** `Instrumenter` interface possible: - - Prefer `ForSingleType` > `ForKnownTypes` > `ForTypeHierarchy` -- Add `classLoaderMatcher()` if a sentinel class identifies the framework on the classpath -- Declare **all** helper class names in `helperClassNames()`: - - Include inner classes (`Foo$Bar`), anonymous classes (`Foo$1`), and enum synthetic classes -- Declare `contextStore()` entries if context stores are needed (key class → value class) -- Keep method matchers as narrow as possible (name, parameter types, visibility) - -## Step 6 – Write the Decorator - -- Extend the most specific available base decorator: - - `HttpClientDecorator`, `DatabaseClientDecorator`, `ServerDecorator`, `MessagingClientDecorator`, etc. -- One `public static final DECORATE` instance -- Define `UTF8BytesString` constants for the component name and operation name -- Keep all tag/naming/error logic here — not in the Advice class -- Override `spanType()`, `component()`, `spanKind()` as appropriate - -## Step 7 – Write the Advice class (highest-risk step) - -### Must do - -- Advice methods **must** be `static` -- Annotate enter: `@Advice.OnMethodEnter(suppress = Throwable.class)` -- Annotate exit: `@Advice.OnMethodExit(onThrowable = Throwable.class, suppress = Throwable.class)` - - **Exception**: do NOT use `suppress` when hooking a constructor -- Use `@Advice.Local("...")` for values shared between enter and exit (span, scope) -- Use the correct parameter annotations: - - `@Advice.This` — the receiver object - - `@Advice.Argument(N)` — a method argument by index - - `@Advice.Return` — the return value (exit only) - - `@Advice.Thrown` — the thrown exception (exit only) - - `@Advice.Enter` — the return value of the enter method (exit only) -- Use `CallDepthThreadLocalMap` to guard against recursive instrumentation of the same method - -### Span lifecycle (in order) - -Enter method: -1. `AgentSpan span = startSpan(DECORATE.operationName(), ...)` -2. `DECORATE.afterStart(span)` + set domain-specific tags -3. `AgentScope scope = activateSpan(span)` — return or store via `@Advice.Local` - -Exit method: -4. `DECORATE.onError(span, throwable)` — only if throwable is non-null -5. `DECORATE.beforeFinish(span)` -6. `span.finish()` -7. `scope.close()` - -### Must NOT do - -- **No logger fields** in the Advice class or the Instrumentation class (loggers only in helpers/decorators) -- **No code in the Advice constructor** — it is never called -- **Do not use lambdas in advice methods** — they create synthetic classes that will be missing from helper declarations -- **No references** to other methods in the same Advice class or in the InstrumenterModule class -- **No `InstrumentationContext.get()`** outside of Advice code -- **No `inline=false`** in production code (only for debugging; must be removed before committing) -- **No `java.util.logging.*`, `java.nio.*`, or `javax.management.*`** in bootstrap instrumentations - -## Step 8 – Add SETTER/GETTER adapters (if applicable) - -For context propagation to and from upstream services, like HTTP headers, -implement `AgentPropagation.Setter` / `AgentPropagation.Getter` adapters that wrap the framework's specific header API. -Place them in the helpers package, declare them in `helperClassNames()`. - -## Step 9 – Write tests - -Cover all mandatory test types: - -### 1. Instrumentation test (mandatory) - -- Spock spec extending `InstrumentationSpecification` -- Place in `src/test/groovy/` -- Verify: spans created, tags set, errors propagated, resource names correct -- Use `TEST_WRITER.waitForTraces(N)` for assertions -- Use `runUnderTrace("root") { ... }` for synchronous code - -For tests that need a separate JVM, suffix the test class with `ForkedTest` and run via the `forkedTest` task. - -### 2. Muzzle directives (mandatory) - -In `build.gradle`, add `muzzle` blocks: -```groovy -muzzle { - pass { - group = "com.example" - module = "framework" - versions = "[$minVersion,)" - assertInverse = true // ensures versions below $minVersion fail muzzle - } -} -``` - -### 3. Latest dependency test (mandatory) - -Use the `latestDepTestLibrary` helper in `build.gradle` to pin the latest available version. Run with: -```bash -./gradlew :dd-java-agent:instrumentation:$framework-$version:latestDepTest -``` - -### 4. Smoke test (optional) - -Add a smoke test in `dd-smoke-tests/` only if the framework warrants a full end-to-end demo-app test. - -## Step 10 – Build and verify - -Run these commands in order and fix any failures before proceeding: - -```bash -./gradlew :dd-java-agent:instrumentation:$framework-$version:muzzle -./gradlew :dd-java-agent:instrumentation:$framework-$version:test -./gradlew :dd-java-agent:instrumentation:$framework-$version:latestDepTest -./gradlew spotlessCheck -``` - -**If muzzle fails:** check for missing helper class names in `helperClassNames()`. - -**If tests fail:** verify span lifecycle order (start → activate → error → finish → close), helper registration, -and `contextStore()` map entries match actual usage. - -**If spotlessCheck fails:** run `./gradlew spotlessApply` to auto-format, then re-check. - -## Step 11 – Checklist before finishing - -Output this checklist and confirm each item is satisfied: - -- [ ] `settings.gradle.kts` entry added in alphabetical order -- [ ] `build.gradle` has `compileOnly` deps and `muzzle` directives with `assertInverse = true` -- [ ] `@AutoService(InstrumenterModule.class)` annotation present on the module class -- [ ] `helperClassNames()` lists ALL referenced helpers (including inner, anonymous, and enum synthetic classes) -- [ ] Advice methods are `static` with `@Advice.OnMethodEnter` / `@Advice.OnMethodExit` annotations -- [ ] `suppress = Throwable.class` on enter/exit (unless the hooked method is a constructor) -- [ ] No logger field in the Advice class or InstrumenterModule class -- [ ] No `inline=false` left in production code -- [ ] No `java.util.logging.*` / `java.nio.*` / `javax.management.*` in bootstrap path -- [ ] Span lifecycle order is correct: startSpan → afterStart → activateSpan (enter); onError → beforeFinish → finish → close (exit) -- [ ] Muzzle passes -- [ ] Instrumentation tests pass -- [ ] `latestDepTest` passes -- [ ] `spotlessCheck` passes - -## Step 12 – Retrospective: update this skill with what was learned - -After the instrumentation is complete (or abandoned), review the full session and improve this skill for future use. - -**Collect lessons from four sources:** - -1. **Build/test failures** — did any Gradle task fail with an error that this skill did not anticipate or gave wrong - guidance for? (e.g. a muzzle failure that wasn't caused by missing helpers, a test pattern that didn't work) -2. **Docs vs. skill gaps** — did Step 1's sync miss anything? Did you consult the docs for something not captured here? -3. **Reference instrumentation insights** — did the reference integration use a pattern, API, or convention not - reflected in any step of this skill? -4. **User corrections** — did the user correct an output, override a decision, or point out a mistake? - -**For each lesson identified**, edit this file (`.claude/skills/apm-integrations/SKILL.md`) using the `Edit` tool: -- Wrong rule → fix it in place -- Missing rule → add it to the most relevant step -- Wrong failure guidance → update the relevant "If X fails" section in Step 10 -- Misleading or obsolete content → remove it - -Keep each change minimal and targeted. Do not rewrite sections that worked correctly. -After editing, confirm to the user which improvements were made to the skill. diff --git
