Anthropic CCAR-F Based on Real Exam Environment

Claude Code supports resuming a specific saved session by either its identifier or its assigned name. Because the engineer knows the target session is named auth-deep-dive , the appropriate command is:

claude --resume auth-deep-dive

Anthropic’s CLI reference explicitly states that --resume can resume a session by ID or name and gives named-session usage in the same form. Resuming restores the relevant conversation history and accumulated context, including the prior analysis and files discussed during the investigation. ( )

Option B is incorrect because --continue resumes the most recent session in the current directory. The engineer has conducted three subsequent sessions, so it may open an unrelated investigation. Option A uses a flag that is not the documented Claude Code mechanism for selecting a prior session; --resume itself accepts the session identifier when an ID is used. Option C discards two hours of established context and unnecessarily repeats codebase exploration.

Named sessions are particularly useful when engineers alternate among multiple projects or parallel investigations. Assigning descriptive names allows the correct thread to be retrieved deterministically rather than depending on chronological recency.

Option B follows the Claude Agent SDK’s subagent context model. A normal subagent begins with a fresh context window and does not inherit the parent agent’s conversation history or prior tool results. Anthropic’s Subagents in the SDK documentation states that the information passed from parent to subagent is the spawning tool’s prompt string; required file paths, decisions, errors, or findings must therefore be included in that prompt. In this scenario, the coordinator should supply both agents’ relevant findings, source metadata, and explicit synthesis instructions. “Complete findings” means the full required result artifacts, not every intermediate search trace. Option C incorrectly assumes automatic context inheritance. Option A introduces callbacks that are neither necessary nor the standard handoff mechanism. Option D can be a valid custom architecture when a shared store has deliberately been implemented, but the question does not establish such infrastructure, and identifiers alone do not give the subagent information. The prompt should use clear sections or structured objects to distinguish web findings, document findings, sources, unresolved conflicts, and expected output. This preserves context isolation while providing everything the synthesis task actually requires.

The failure is caused by an underspecified extraction policy rather than an inadequate JSON structure. “Extract all skills mentioned” does not define whether coordinated phrases should be split, whether inferred capabilities qualify, or what level of specificity constitutes one skill. Few-shot examples can demonstrate all three decisions using concrete inputs and expected outputs.

Anthropic identifies examples as one of the most effective ways to improve output accuracy and consistency because they communicate behavior more precisely than abstract instructions alone. Representative examples can show that “Python and SQL” becomes two entries, that an unstated skill must not be inferred from a job title, and that broad descriptions should not be decomposed into dozens of speculative micro-skills. ( )

Option A adds provenance and confidence metadata but does not define the correct extraction granularity. Option C addresses explicitness and splitting, but the arbitrary 10–20 limit can truncate documents containing more than 20 legitimate skills or force padding when fewer than 10 appear. Option D is useful for canonicalization and deduplication, but post-processing cannot reliably remove plausible implied skills or determine how the original phrase should have been interpreted.

The strongest prompt should combine explicit rules with diverse few-shot examples covering normal cases, compound phrases, implied information, duplicates, and unusually long or short skill lists.

Option B creates the granular error taxonomy needed to understand recurring false-positive patterns. The existing issue_category field is too broad: a high dismissal rate for style does not reveal whether developers object to single-letter variables, line-length warnings, naming conventions, or something else. Recording the detected construct allows dismissal rates to be grouped by trigger and connected to targeted prompt revisions or project-specific examples.

Anthropic’s evaluation guidance recommends measurable, task-specific criteria and evaluation cases that reflect real production behavior and edge cases. Its structured-output documentation supports schema-constrained, parseable records suitable for this type of downstream analysis.

Option A can help rank findings, but a confidence score does not explain why developers reject them and may be poorly calibrated across issue types. Option C produces more text without adding a stable dimension for aggregation. Option D removes useful category information and makes systematic analysis harder. A normalized detected_pattern field enables dashboards, pattern-level dismissal metrics, representative-example sampling, and controlled evaluations of prompt changes while retaining the broader category for higher-level reporting.
