About Cynthia
Cynthia writes where enterprise data meets agent behavior. On the data side that is natural-language querying against real schemas — the retail reporting work that turns fragmented store data into conversational analytics, and the healthcare NLQ deployment behind the review byline — plus EDI 270/271 eligibility checks, where a 96%-electronic X12 standard and the CAQH CORE operating rules still leave clinics phoning payers because the response omits the one field the front desk needed.
On the agent side Cynthia wrote the layered prompt-injection defense model built on OWASP LLM01, least privilege, and output validation, and the guardian-agent glossary entry on systems that review, monitor, and veto other agents. Cost work rounds it out: the Bedrock pricing guide with per-task loop arithmetic instead of rate-card math, and Claude model routing by cost-per-task across Haiku, Sonnet, and Opus. Expect schema-level detail and numbers taken from measured tasks.
