## AI interpretation — verify before relying

Adds distributed tracing to Flask web applications by instrumenting HTTP requests and responses through OpenTelemetry, building on WSGI middleware to capture request spans and metadata.

Verdict: A well-maintained, actively developed instrumentation library for adding distributed tracing to Flask applications. Low install friction, permissive licensing, and no known vulnerabilities make it a solid choice for Flask observability. The Beta status and requirement for Python 3.10+ are minor considerations for modern deployments.
