Research direction

Start by tracing the headersCommand failure path and how Telemetry.maskString feeds status.error, mcp list, and logs. Determine whether the project expects entropy-based redaction or documentation of the residual risk; done requires an agreed approach that prevents or clearly records exposure of bare unprefixed tokens.

Written by the indexing model from the issue text.

Description

Found during v0.9.1 release review (CTO). Telemetry.maskString() only redacts known shapes (sk-…, Bearer , emails, hosts). A verbose auth CLI in headersCommand that prints a bare unprefixed token to stderr on failure would surface unmasked in status.error/mcp list/logs. Consider entropy-based redaction for the headersCommand failure path, or document the residual risk.
