Stratified random sampling provides both an ongoing quality-control mechanism and an unbiased measurement framework. By reviewing a fixed proportion of high-confidence outputs across meaningful strata—such as document type, field, source format, and business risk—the organization can estimate the residual error rate, compare performance across releases, and discover failure patterns that were not anticipated when existing rules were designed.

Anthropic recommends measurable success criteria and evaluations that mirror the real-world task distribution, including edge cases. Evaluation volume and repeatability are important because improvements must be demonstrated empirically rather than inferred from isolated examples. ( ) A weekly sampling program creates a stable benchmark and allows confidence intervals, trend analysis, regression detection, and error-taxonomy updates.

Option A detects only disagreements between stochastic extractions. Two attempts may produce the same plausible but incorrect answer, so agreement is not equivalent to factual correctness. Option B addresses known patterns but will miss new failure modes and may generate excessive false positives. Option C actually lowers the review threshold in the wrong direction: documents between 70% and 85% would be treated as automated rather than reviewed if the routing rule remains “below threshold,” and changing thresholds alone does not measure high-confidence error prevalence.

MCP prompts are exposed as user-invoked commands rather than autonomous tools or permanently loaded system instructions. Claude Code dynamically discovers prompts from connected MCP servers and displays them in the command list using the naming convention /mcp__servername__promptname .

Arguments are supplied as space-separated values after the command. When executed, the MCP server resolves the prompt and its returned content is injected into the active conversation. Anthropic’s official documentation provides examples such as /mcp__github__list_prs and /mcp__jira__create_issue "Bug in login flow" high . ( )

Option A would consume context continuously and incorrectly treat optional workflow templates as mandatory system instructions. Option B confuses MCP prompts with MCP tools: tools are model-callable operations, while prompts are reusable prompt templates invoked as commands. Option C describes MCP resources, which can be referenced and attached but are a distinct MCP capability.

For the stated server, the team could invoke commands such as /mcp__devops__deploy_checklist or /mcp__devops__incident_response service-name . The exact server segment is derived from the configured server name, with normalization applied where necessary.

The most reliable architecture separates semantic interpretation from deterministic normalization. Claude is well suited to identifying that “$12” and “12.00” represent prices, or that a leaf icon represents a dietary classification. However, canonical conversion—removing currency symbols, converting values to decimal types, mapping icons to controlled labels, and enforcing locale-specific rules—is more predictably performed in application code.

Structured Outputs guarantee that Claude returns valid JSON matching the supplied schema, but that guarantee concerns structural conformance. It does not by itself guarantee that every semantically equivalent source representation will be normalized identically. Anthropic’s evaluation guidance identifies code-based checks as the fastest, most reliable, and most scalable mechanism for rule-based validation. ( )

Option D therefore minimizes model responsibility: Claude extracts the evidence as represented, and deterministic post-processing converts it into the canonical downstream format. This also makes normalization rules independently testable, version-controlled, and auditable.

Option A increases latency and cost without solving normalization. Option B improves output structure, but prompt-based normalization can still vary across ambiguous formats. Option C introduces unnecessary stochasticity and majority-vote logic where explicit parsing rules are available. The downstream contract should remain stable, but format conversion should be implemented using deterministic transformations rather than repeated probabilistic inference.

First-contact resolution does not require pretending that every backend operation succeeded. The agent can still resolve the informational portion of the interaction by explaining the charge and confirming eligibility using the successfully retrieved customer and order data. It must then distinguish that verified conclusion from the uncompleted refund transaction.

Anthropic’s tool-error guidance states that Claude should receive the failure information so it can retry, request clarification, or explain the limitation. A tool timeout must therefore be surfaced honestly rather than converted into an unsupported success claim. ( ) Anthropic also emphasizes transparent, simple agent designs and carefully constructed tool interfaces, which support explicit disclosure of tool failure and controlled escalation. ( )

Option A can create an unbounded or excessively long interaction; retries should be limited and conditioned on retryability. Option B falsely represents an incomplete financial operation as completed. Option D discards the useful work already performed and escalates before providing the customer with the available explanation.

Option C preserves trust, delivers the information already established, clearly states what remains incomplete, and gives the customer a practical next step through bounded retry or human escalation.
