Show HN: Ducktel – observability when the consumer is an AI agent, not a human

Receives OTLP, writes Parquet, exposes DuckDB SQL via CLI. No dashboards, no query builders, no alerting engine. An LLM agent shells out to ducktel query, gets JSON back, and does the reasoning itself. The thesis: everything observability platforms built above ingest+store was scaffolding for human cognition. When the consumer is an LLM, the scaffolding is just overhead.
