| description | Find the Java implementation class behind a Membrane interceptor or config element given its XML name (the @MCElement value), e.g. "which class implements the <groovy> interceptor?". Use whenever the user references an interceptor / plugin / config element by its proxies.xml tag name (groovy, apiKey, rewriter, log, ...) and wants the source file or class, or asks where an interceptor is implemented / defined / configured. Also use the reverse direction — going from a class name to its config element name. |
Find Interceptor Implementation
In Membrane, every interceptor (and most config elements) is wired to an XML
config tag by an @MCElement(name = "...") annotation on its Java class. The tag
<groovy> in proxies.xml is implemented by the class annotated
@MCElement(name = "groovy") — GroovyInterceptor. This skill maps between the
two directions.
Name → implementation class (the common case)
Run the helper with the XML element name:
.claude/skills/find-interceptor-impl/find-interceptor-impl.sh groovy
It prints the class and file, searching every module's src/main/java (the
annotation is not limited to core):
Implementation class for <groovy>:
GroovyInterceptor -> ./core/src/main/java/.../groovy/GroovyInterceptor.java
Class → element name (reverse direction)
Given a class name, find its file and annotation in one shot — no need to know
which module it lives in first:
grep -rn --include='GroovyInterceptor.java' '@MCElement' .
The name = "..." value is the tag used in proxies.xml. No match means the
class isn't directly configurable — it's likely an abstract base or exposed
under a parent element; check its subclasses for the nearest one carrying
, or grep / for how it's
actually used.
