Option C directly searches source-file contents for imports of @company/auth . Anthropic’s Claude Code tools reference states that Grep locates patterns within files, while Glob matches filenames and paths. The search can account for the repository’s supported module syntaxes, including static imports, require() calls, dynamic imports, and re-exports. It can also restrict results by file type or directory when appropriate. Option A identifies packages that declare the dependency but does not prove which source files import or invoke it; workspace-level dependency declarations may cover many packages. Option B finds authentication-related filenames, which are unrelated to whether a file imports the package. Option D searches directory names and therefore has the same limitation. After Grep returns the matching files and line numbers, the agent can read the surrounding code to determine whether each import supports middleware registration, token verification, authorization checks, or re-exporting. This produces an accurate usage inventory while minimizing context consumption and unnecessary file reads.

Option C gives the human agent the operational state required to continue without replaying a long conversation. The handoff should include verified identifiers, the duplicate transaction evidence, the diagnosed timeout-and-retry mechanism, the $847 refund requirement, the agent’s $500 authorization constraint, completed verification steps, prior actions, and the recommended resolution. Any unresolved uncertainty should be labeled explicitly.

Anthropic’s effective context-engineering guidance recommends preserving high-value state in structured notes while removing redundant conversational and tool-call history. Its long-running-agent guidance likewise describes structured handoffs as the mechanism for maintaining continuity across context resets or agent boundaries.

Option A maximizes raw information but forces the human to locate the relevant facts among more than 25 turns, increasing delay and error risk. Option B preserves evidence but omits the authorization constraint, completed verification, and explicit recommended action. Option D is too sparse to support validation or execution. A structured handoff balances fidelity and efficiency: it contains everything needed for the next actor to make the refund decision while excluding greetings, repeated explanations, and irrelevant intermediate tool output.

Option B combines lossless persistence with selective restoration. Each agent should checkpoint structured records containing completed document IDs, extracted findings, source metadata, unresolved work, validation status, and schema version. A coordinator-level manifest records where those artifacts are stored and which pipeline stages completed. On resumption, the coordinator can skip the 12 completed documents and inject only the artifacts relevant to each restarted agent. Anthropic’s effective context-engineering guidance recommends structured note-taking outside the context window so agents can preserve project state across resets while loading only the information needed later. A vector store, option A, is useful for relevance retrieval but can omit exact details through similarity-based selection and is unsuitable as the sole recovery record. Option C fragments ownership of recovery state and makes cross-agent consistency difficult to verify. Option D preserves an extensive trace, but replaying a complete conversation wastes context and mixes obsolete instructions, intermediate reasoning, and redundant outputs. Structured checkpoints plus a manifest provide deterministic recovery, auditability, exact provenance, and efficient prompt reconstruction. Checkpoints should be written atomically and validated before the corresponding stage is marked complete.

The problem is an undefined relevance threshold. Claude is finding technically valid observations, but the prompt does not clearly distinguish actionable defects from acceptable conventions and low-value style preferences. Option A establishes explicit positive and negative reporting criteria, allowing the model to apply the team’s actual definition of a useful finding during generation.

Anthropic’s prompt-engineering guidance emphasizes clear, specific instructions and well-defined success criteria. The managed Code Review documentation similarly recommends defining skipped categories, generated paths, severity rules, and evidence requirements. Reporting “bugs affecting correctness or security” while excluding “formatting handled by CI and documented local conventions” is substantially more precise than asking the model to be generally conservative.

Option B adds cost, latency, another probabilistic decision, and a new evaluation surface before improving the original prompt. Option C confuses confidence with importance: Claude may be highly confident about a trivial style observation. Option D is dangerously broad because it can suppress legitimate but uncertain bugs, reducing recall. Explicit relevance criteria address the demonstrated failure directly while preserving the model’s ability to investigate and report genuine correctness or security problems.
