Answer the traceability question: $ARGUMENTS

Step 1: Parse the question type

Determine which traceability pattern applies:

• Requirement to test: "Which tests verify requirement X?"
• Feature to code: "What code implements feature Y?"
• Code to test: "Is function Z tested?"
• Gap analysis: "Find untested code" or "Find unimplemented requirements"

Step 2: Find the anchor node

Call acm_search(pattern="<entity>") to find the node the question is about.

Step 3: Trace across layers

Call acm_trace(node_id) to see all cross-layer connections grouped by layer.

Step 4: Follow specific paths

For targeted questions, call acm_paths(source, target) between specific nodes.

Step 5: Use natural language (optional)

For complex questions, call acm_query_router(query="<question>") which uses multi-channel search (graph + text + vector).

Step 6: Report findings

Present the traceability chain: requirement -> feature -> design -> code -> test. Highlight any gaps in the chain.
