This skill addresses the difficulty of diagnosing complex failures in Agoric swingset environments by providing a structured method to interpret slog files and flight recorder binary data.
Use the slog-debugging skill to identify the failing delivery in the captured flight-recorder.bin file.

To debug Agoric swingset vat delivery failures, you analyze slog files and flight recorder binary data to correlate kernel-level events with specific XS engine aborts. This process isolates the root cause by tracking the failing vat delivery and its incarnation.
A flight recorder binary in Agoric XS engine debugging is captured runtime data that preserves the state before a crash. It is required to trace back from stack meter exhaustion errors to the specific vat delivery that triggered the failure.
To capture flight recorder data before test teardown, you must explicitly save the flight-recorder.bin file immediately upon detecting an XS engine abort. Preserving this artifact prevents data loss and allows subsequent grep-based log parsing.
To find the root cause of an XS engine stack meter exhaustion abort, you walk back from the error records in the slog to the specific vat delivery. You use incarnation tracking to isolate the exact delivery that triggered the failure.
Yes, slog debugging requires systematic grep-based log parsing to filter Agoric swingset records. Grep is utilized to extract relevant kernel-level events from the slog file and correlate them with delivery outcomes.
Yes, you can diagnose xsnap aborts using slog files in agoric-sdk development. By correlating slog records with flight recorder data, you systematically identify the specific XS engine errors and isolate the failing vat incarnation.
