You are compiling a diagnostic toolkit for Claude Code operational issues.
Which two diagnostic actions belong in the toolkit? (Select two.)
Each correct answer presents a complete solution.

• A. Increase the model sampling temperature so that intermittent issues surface more frequently for analysis.
• B. List the configured Model Context Protocol (MCP) servers and inspect server status to identify connection failures.
• C. File a support ticket with vendor support before any local reproduction or evidence collection.
• D. Reproduce the issue with a minimal reproduction case that isolates one variable at a time.
• E. Roll back to the previous Claude Code version immediately to confirm whether the issue is version specific.

The compliance team at a firm has approved a Claude Skill that generates client-facing investment summaries. The Skill includes the firm's required disclaimers and prohibited-language list. A product manager has asked whether additional guardrails are needed at the application layer or whether the Skill alone is sufficient.
Which two guardrail responsibilities should remain at the application layer rather than the Skill? (Select two.) Each correct answer presents part of the solution.

• A. Format output sections according to the firm's standardized house style guidelines.
• B. Verify the requesting user is authorized to generate investment summaries at all.
• C. Apply the prohibited-language list that the compliance team maintains and updates.
• D. Log every generated summary to the firm's compliance audit trail for retention.
• E. Apply the disclaimer template that the compliance team has standardized firm-wide.

A healthcare organization is evaluating two Claude-powered AI architectures for a clinical documentation assistant. Architecture X produces higher output quality scores but costs $0.18 per documentation session and averages 4.2 seconds per response. Architecture Y scores slightly lower on quality metrics but costs $0.09 per session and averages 2.1 seconds per response. The stated SLA requires responses under 3 seconds, and the annual volume is projected at 2 million documentation sessions.
Which evaluation approach correctly applies business value pillar analysis to this decision?

• A. Recommend a hybrid approach using Architecture X for complex cases and Architecture Y for routine cases, without additional analysis, since this preserves quality where it matters most.
• B. Eliminate Architecture X on SLA grounds, then evaluate Architecture Y against the efficiency and solution cost pillars by calculating annual cost difference and assessing whether the quality delta materially impacts clinical workflow productivity.
• C. Select Architecture Y based solely on the 50% cost reduction, since solution cost is the most important value pillar in healthcare budget-constrained environments.
• D. Select Architecture X because the higher quality scores justify the cost premium, and any SLA gap can be addressed through infrastructure optimization after deployment.

An engineer inadvertently commits an API key to the repository by placing it in .claude/settings.json.
Which configuration design principle was violated?

• A. MCP server definitions must reside in environment variables to prevent scope conflicts.
• B. Credentials must be resolved at runtime from a secret store and never stored in version-controlled files.
• C. Managed configuration must be applied before project-scope configuration is read.
• D. Project-scope configuration should always override user-scope configuration.
