Pass Anthropic CCA-F Exam in First Attempt Easily

The next stage cannot distinguish missing data from failed access. This alternative suggests “Return only “chart failed” with no retrieval context”, whereas the supported approach is “Supply the exact retrieval error and whether data was absent or access failed”. Root cause determines whether to retry, seek permission or report no data. Failures must propagate honestly through the agent chain: a timeout, partial result or permission denial is not the same as a successful empty response.

“Invent a blank chart and label it successful” is the wrong action for this case. An empty graphic is not evidence of no measurements. The supported choice is “Supply the exact retrieval error and whether data was absent or access failed”. Root cause determines whether to retry, seek permission or report no data. Keep the failing operation’s identity, successful prior work, provenance and recovery choices available so downstream agents can make an informed decision.

The cause must be classified before recovery. The proposal “Retry the same missing source indefinitely” conflicts with the required decision. “Supply the exact retrieval error and whether data was absent or access failed” addresses the actual condition. Root cause determines whether to retry, seek permission or report no data. Failures must propagate honestly through the agent chain: a timeout, partial result or permission denial is not the same as a successful empty response.

“Keep reading the entire repository without verifying invented class names” is the wrong action for this case. Large context alone does not validate symbols. The supported choice is “Re-ground on targeted search results and persist a concise verified repository map”. Large-context degradation requires renewed evidence rather than plausible guesses. Use targeted inspection and retrieval to update only stale context, then check how a proposed change interacts with neighboring modules and contracts.

Targeted source search is more reliable. The proposal “Use guessed APIs until compiler errors reveal their names” conflicts with the required decision. “Re-ground on targeted search results and persist a concise verified repository map” addresses the actual condition. Large-context degradation requires renewed evidence rather than plausible guesses. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

A concise verified map avoids redundant work. This alternative suggests “Erase all collected file references and begin the same broad exploration”, whereas the supported approach is “Re-ground on targeted search results and persist a concise verified repository map”. Large-context degradation requires renewed evidence rather than plausible guesses. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

Compaction can lose essential relationships. The proposal “Trust the compressed conversation to preserve every service dependency” conflicts with the required decision. “Store a structured dependency map and key file locations as durable context” addresses the actual condition. Explicit state preserves discovered architecture across context boundaries. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

It does not identify files or dependencies. This alternative suggests “Save only “refactor in progress” in a notes field”, whereas the supported approach is “Store a structured dependency map and key file locations as durable context”. Explicit state preserves discovered architecture across context boundaries. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

“Reconstruct the dependency graph from memory on every restart” is the wrong action for this case. Durable, source-linked state is safer. The supported choice is “Store a structured dependency map and key file locations as durable context”. Explicit state preserves discovered architecture across context boundaries. Use targeted inspection and retrieval to update only stale context, then check how a proposed change interacts with neighboring modules and contracts.

The source of overload remains. This alternative suggests “Copy entire logs into the parent again with a longer context window”, whereas the supported approach is “Delegate log exploration and return filtered evidence with locations”. Specialized exploration can keep the main session within a useful context budget. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

“Discard error timestamps and line identifiers during summarization” is the wrong action for this case. Filtered evidence still needs traceable locations. The supported choice is “Delegate log exploration and return filtered evidence with locations”. Specialized exploration can keep the main session within a useful context budget. Use targeted inspection and retrieval to update only stale context, then check how a proposed change interacts with neighboring modules and contracts.

Targeted exploration should supply real indicators. The proposal “Ask the debugging agent to guess the root cause without inspecting the logs” conflicts with the required decision. “Delegate log exploration and return filtered evidence with locations” addresses the actual condition. Specialized exploration can keep the main session within a useful context budget. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

Prior side effects may already have completed. This alternative suggests “Restart all migration operations blindly after a crash”, whereas the supported approach is “Persist the completed steps, open tasks, file revisions and recovery pointers”. Durable migration state should record completed commands, pending tasks, file revisions and recovery pointers so a restart does not replay side effects blindly. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

“Store only the last status message with no file revision or task IDs” is the wrong action for this case. Recovery needs an exact checkpoint. The supported choice is “Persist the completed steps, open tasks, file revisions and recovery pointers”. Durable migration state should record completed commands, pending tasks, file revisions and recovery pointers so a restart does not replay side effects blindly. Use targeted inspection and retrieval to update only stale context, then check how a proposed change interacts with neighboring modules and contracts.

A worker crash does not guarantee that previous writes were rolled back; durable task and transaction records are needed before replay. The proposal “Assume interrupted commands rolled back automatically” conflicts with the required decision. “Persist the completed steps, open tasks, file revisions and recovery pointers” addresses the actual condition. Durable migration state should record completed commands, pending tasks, file revisions and recovery pointers so a restart does not replay side effects blindly. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

“Continue coding against the saved API contract without checking new commits” is the wrong action for this case. The interface may have changed. The supported choice is “Inspect the current contract and reconcile earlier notes before continuing”. Repository state can supersede saved context and must be revalidated. Use targeted inspection and retrieval to update only stale context, then check how a proposed change interacts with neighboring modules and contracts.

That can destroy valid updates. The proposal “Overwrite colleagues' changes to restore the old contract silently” conflicts with the required decision. “Inspect the current contract and reconcile earlier notes before continuing” addresses the actual condition. Repository state can supersede saved context and must be revalidated. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

The working tree has evolved since that test. This alternative suggests “Assume a passing previous build proves compatibility now”, whereas the supported approach is “Inspect the current contract and reconcile earlier notes before continuing”. Repository state can supersede saved context and must be revalidated. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

A later worker cannot reliably locate it. The proposal “Keep only the helper function's informal nickname” conflicts with the required decision. “Record the function name, path, behavior and supporting source snippet in a scratchpad” addresses the actual condition. Structured snippets enable later precise lookup. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

Pasting the complete discovery report into every prompt repeats irrelevant context and can obscure the specific helper function. This alternative suggests “Copy the entire report into every subsequent prompt”, whereas the supported approach is “Record the function name, path, behavior and supporting source snippet in a scratchpad”. Structured snippets enable later precise lookup. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

“Omit the behavior and source snippet when storing the path” is the wrong action for this case. The assistant needs why the function matters. The supported choice is “Record the function name, path, behavior and supporting source snippet in a scratchpad”. Structured snippets enable later precise lookup. Use targeted inspection and retrieval to update only stale context, then check how a proposed change interacts with neighboring modules and contracts.

Most of that context is irrelevant to the fix. This alternative suggests “Reload the entire architecture discussion before changing the one target function”, whereas the supported approach is “Load only relevant facts and files for the targeted repair”. Context should narrow as task focus narrows. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

“Ignore all verified dependencies because the edit is local” is the wrong action for this case. A targeted context still needs related constraints. The supported choice is “Load only relevant facts and files for the targeted repair”. Context should narrow as task focus narrows. Use targeted inspection and retrieval to update only stale context, then check how a proposed change interacts with neighboring modules and contracts.

Focused source reads prevent hallucinated edits. The proposal “Invent the function's location from the summary instead of locating it” conflicts with the required decision. “Load only relevant facts and files for the targeted repair” addresses the actual condition. Context should narrow as task focus narrows. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

The claim gives no reproducible evidence. This alternative suggests “Store only “authentication reviewed” as the durable state”, whereas the supported approach is “Persist inspected file paths, conclusions and unresolved dependencies”. A vague note is insufficient to resume a technical investigation. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

“List file names but omit conclusions and open questions” is the wrong action for this case. Future work cannot distinguish complete from pending investigation. The supported choice is “Persist inspected file paths, conclusions and unresolved dependencies”. A vague note is insufficient to resume a technical investigation. Use targeted inspection and retrieval to update only stale context, then check how a proposed change interacts with neighboring modules and contracts.

A review note is not authorization. The proposal “Treat the high-level note as approval for identity changes” conflicts with the required decision. “Persist inspected file paths, conclusions and unresolved dependencies” addresses the actual condition. A vague note is insufficient to resume a technical investigation. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

“Paste the subagent's complete repository-exploration transcript into the parent” is the wrong action for this case. Verbose discovery crowds out active work. The supported choice is “Require a concise findings schema with paths, evidence and next steps”. A summary contract preserves useful discovery without flooding primary context. Use targeted inspection and retrieval to update only stale context, then check how a proposed change interacts with neighboring modules and contracts.

The parent cannot use or verify the investigation. The proposal “Return “repository checked” without paths or findings” conflicts with the required decision. “Require a concise findings schema with paths, evidence and next steps” addresses the actual condition. A summary contract preserves useful discovery without flooding primary context. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

Concise summaries still need actionable references. This alternative suggests “Strip source pointers from the condensed report”, whereas the supported approach is “Require a concise findings schema with paths, evidence and next steps”. A summary contract preserves useful discovery without flooding primary context. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

That wastes effort and risks divergent conclusions. The proposal “Repeat every prior module analysis after each restart without checking revisions” conflicts with the required decision. “Save a versioned progress manifest tied to verified file revisions” addresses the actual condition. Persistent state avoids repeated analysis while detecting stale findings. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

The process cannot tell which findings are still valid. This alternative suggests “Store a checklist with no source versions or status evidence”, whereas the supported approach is “Save a versioned progress manifest tied to verified file revisions”. Persistent state avoids repeated analysis while detecting stale findings. Large codebase work requires refreshed repository and dependency evidence because previous summaries and cached tool results may no longer describe the current files.

“Assume unchanged filenames guarantee unchanged source behavior” is the wrong action for this case. Revisions, not names alone, determine freshness. The supported choice is “Save a versioned progress manifest tied to verified file revisions”. Persistent state avoids repeated analysis while detecting stale findings. Use targeted inspection and retrieval to update only stale context, then check how a proposed change interacts with neighboring modules and contracts.
