Agent Trace Inspector

Local-first observability for agent workflows with tool call tracing, token cost estimation, trace comparison, and exportable HTML dashboards.

Records every tool call, prompt transformation, latency measurement, and token count in a local SQLite database for agent workflow observability. Generates self-contained HTML dashboards with interactive step timelines, calculates USD cost estimates per trace using a configurable pricing table, and supports side-by-side trace comparison to measure the impact of prompt or tool changes. Includes OpenTelemetry export, compliance audit logging, configurable alert rules, and retention policies. Designed specifically for the protocol rather than adapted from a generic LLM proxy.
