Get the Instrumentation Score specification
AI agents call get_instrumentation_score_spec to retrieve information from Otel Instrumentation without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns a specification document without modifying, executing, or deleting anything. It is purely informational, making it a Read category tool with low severity risk—an AI agent cannot cause harm by requesting a specification document.
From the tool's definition Tool name 'get_instrumentation_score_spec' and description 'Get the Instrumentation Score specification' indicate a retrieval operation. The verb 'get' and the read-only nature of fetching a specification document confirm no side effects.

{
"version": "1",
"default": "deny",
"tools": {
"get_instrumentation_score_spec": {}
}
