Claude Certified Architect CCAR-F Release Date

An aggregate accuracy value can conceal severe performance disparities. A system may achieve 97% overall accuracy while performing poorly on a low-volume document type, a critical financial field, or a specific edge case. Automating outputs solely from the aggregate figure could therefore expose downstream systems to concentrated, high-impact errors.

Anthropic’s evaluation guidance states that evaluations should be task-specific, reflect the real-world task distribution, and explicitly include edge cases. It also emphasizes multidimensional success criteria rather than reliance on a single global metric. ( ) Option A applies those principles by stratifying performance according to document type and field. This reveals whether confidence is calibrated consistently and whether the proposed automation threshold remains safe for every operationally significant segment.

Option B is useful only after segment-level performance has been understood. Selecting a global threshold cannot correct a subgroup where confidence is systematically overstated. Option C is necessary governance work, but it treats the overall 97% result as though errors were uniformly distributed. Option D places unvalidated outputs into downstream systems and depends on passive error reporting, which may fail to detect silent corruption.

The correct deployment gate is therefore segmented validation, followed by threshold selection, downstream acceptance criteria, and a controlled pilot.

Option D fixes the actual failure while avoiding needless reprocessing. Anthropic’s Message Batches API treats every request independently, records the result against its unique custom_id, and explicitly states that one failed request does not affect the others. The 9,700 successful documents therefore require no retry. The failed requests exceeded the available context; increasing max_tokens changes the permitted output budget, not the size of the input context, so option C does not correct the cause. Resubmitting all 10,000 requests would repeat paid work, and prompt caching would only reduce some repeated-input cost without repairing oversized requests. Chunking each failed document reduces the input presented to Claude so every replacement request fits within the model’s context window . The application can then merge the extracted partial structures deterministically, retaining the original document identifier and chunk ordering. Anthropic recommends retry logic for failed batch requests and using custom_id to match results because batch results can arrive out of order. Consequently, selective retry plus chunking is both the technically correct recovery path and the lowest-cost option.

================

Option C parallelizes independent work while retaining centralized orchestration. Each precedent can be analyzed without waiting for the previous precedent, so the coordinator can divide the 12 cases into balanced subsets and invoke several document-analysis subagents concurrently. It then receives their final outputs, records which precedents completed or failed, and aggregates the results before synthesis. Anthropic’s multi-agent research architecture uses an orchestrator-worker pattern in which the lead agent creates specialized subagents that operate in parallel and return findings for consolidation. Keeping spawning decisions at the coordinator also produces a clearer execution trace for monitoring and debugging. A generic asynchronous queue, option A, adds infrastructure but does not define how results remain associated with the correct research task. Options B and D create nested or recursive delegation, making execution paths, permissions, failures, and token consumption harder to observe. Anthropic also cautions that multi-agent systems consume substantially more tokens than ordinary interactions, so unbounded recursive decomposition is inefficient. Coordinator-controlled parallel fan-out followed by deterministic aggregation provides the latency improvement without sacrificing operational visibility.

================

The checklist is a reusable, task-specific procedure that should load only when a pull-request review is being performed. A /review command provides an explicit invocation mechanism, prevents repeated copy-and-paste, and keeps the checklist out of unrelated coding, debugging, and documentation sessions.

In current Claude Code terminology, custom commands have been consolidated into skills. A .claude/skills/review/SKILL.md file creates a /review command, while the legacy .claude/commands/review.md format remains supported. Anthropic recommends skills when users repeatedly supply the same checklist or multi-step procedure; unlike CLAUDE.md content, the skill body is loaded only when invoked or determined relevant. ( )

Option B introduces an isolated agent context when the requirement is primarily to inject a repeatable review procedure. A subagent could be useful for independent verification, but it is not necessary merely to avoid repasting the checklist. Option C bloats every session with instructions that apply only to code review. Option D controls editing permissions and planning behavior; it does not encode review criteria.

The review skill can also pre-authorize read-only tools and accept a pull-request identifier or branch as an argument.
