data-freshness

Data freshness verification for AI agents. Probes endpoints for cache staleness, latency, TLS health, and content changes. CLI + MCP server + HTTP API.

Use API caching in API Gateway to cache your responses. Reduce calls made to backend and improve latency of requests to your API

Transitive evidence freshness and integrity checks for long-running AI agents, RAG pipelines and autonomous workflows.

Public environmental monitoring dashboard for Clear Lake, CA — integrating USGS hydrology, FHABS HAB reports, and OSM geospatial data

A vendor-neutral OpenTelemetry semantic convention for data staleness (data freshness), plus a Python SDK and Go Collector components.

Claims Registry Kit | Dependency-free TypeScript tracking for product claims, evidence references, and overdue reviews.

Rego policy that treats data freshness as part of the authorization decision. Escalates on stale data instead of guessing. Fail-closed on invalid input.

Freshness-aware observability of port environmental monitoring: temporal-graph model, experiments and reproducible results

Learns each dataset's own arrival distribution instead of applying one fixed freshness rule to everything: 86% fewer false alarms than an "alert if not loaded by 07:00" rule at 99.4% detection, plus lineage-aware alert suppression and per-dashboard trust scores. DuckDB, Python, Airflow-shaped, zero cloud credentials.

Declarative, scheduled refresh pipeline for map data: pull GeoJSON/JSON/CSV from HTTP APIs, files or SQL, transform and validate it, detect real changes with an order-stable content hash, and emit a freshness manifest plus a stale-data badge. Includes a composite GitHub Action that rebuilds only when the data moved.

Validate downloaded partner CSV/Parquet feeds locally after SFTP/S3, then alert on missed rolling receipts.
