Logging

When to Use

Use this skill when the user wants to capture, route, filter, or silence ovstage's log output: install a log callback, set a severity threshold, filter by channel, or flush pending messages before a checkpoint. For operation/return-code error handling (not logging), use the error-handling skill instead.

Inputs

Resolve inputs in this order: existing repository files and referenced snippets, explicit user request, then broader agent context.

• The desired default severity threshold (LogSeverity / ovstage_log_severity_t).
• Any per-channel overrides (a comma-separated <channel>=<level> filter).
• Target API surface: C, Python, or both.
• Whether the caller needs a barrier (flush_log) before reading captured output.
• The shipped headers (ovstage.h, ovstage_types.h) and the referenced test snippet are the authoritative contract.
