Anthropic CCA-F Questions & Answers

Duplicate state changes can result from unknown partial completion. A second mutation can duplicate a payment or entitlement if the earlier write actually committed. A crash after a committed account mutation creates an uncertain continuation state rather than a clean rollback. A subagent crashes after committing one account change but before returning its completion receipt. Instead, report the confirmed committed step and unknown continuation state so the coordinator can reconcile.

Continuation state remains uncertain and needs reconciliation. One receipt proves a completed substep, not the status of later unacknowledged operations. A crash after a committed account mutation creates an uncertain continuation state rather than a clean rollback. Instead, report the confirmed committed step and unknown continuation state so the coordinator can reconcile.

A committed step may already have taken effect. A crash after commit cannot be interpreted as evidence of a clean rollback. A crash after a committed account mutation creates an uncertain continuation state rather than a clean rollback. Instead, report the confirmed committed step and unknown continuation state so the coordinator can reconcile.

Unverified reconstruction risks inconsistent conclusions. Reconstructing owners from memory after restart can conflict with source evidence. Long-running code investigations should persist verified module ownership, sensitive APIs and unresolved questions in structured notes. Instead, record structured high-value findings in a persistent scratchpad.

Unstructured volume conceals high-value architectural facts. Unverified handoff notes can turn an exploratory guess into a false architecture constraint. A long investigation repeatedly forgets the mapped module owners and high-risk APIs. Instead, record structured high-value findings in a persistent scratchpad.

Long sessions can compact away module ownership details. Raw findings may be lost from context before the agent needs the module ownership decision. A long investigation repeatedly forgets the mapped module owners and high-risk APIs. Instead, record structured high-value findings in a persistent scratchpad.

Names do not establish actual import relationships. Directory names alone do not prove which modules call or depend on a target symbol. Tracing all import edges would flood the lead agent's context. Instead, assign focused dependency search and return a compact graph summary.

A scoped dependency role should remain observational. Reconnaissance should identify source edges without mutating the code under investigation. Tracing all import edges would flood the lead agent's context. Instead, assign focused dependency search and return a compact graph summary.

Verbose exploration consumes its reasoning context. Long import dumps push critical call paths out of the lead agent's available context. Tracing all import edges would flood the lead agent's context. Instead, assign focused dependency search and return a compact graph summary.

Remaining dependent tasks may still be pending. Three finished specialists do not prove all dependent synthesis tasks also completed. Reloading only unfinished tasks prevents duplicate review reports and unnecessary API or tool calls. A research run is interrupted after three subagents complete their work.

Already completed work is needlessly repeated. Already completed analyses may be billed twice and produce inconsistent duplicate findings. A verified task manifest can distinguish finished specialist work from pending dependent steps after interruption. A research run is interrupted after three subagents complete their work. Instead, persist the completed-agent manifest and reload only unfinished dependent tasks.

The coordinator loses its basis for selective continuation. Removing receipts destroys the evidence used to distinguish finished and pending work. A research run is interrupted after three subagents complete their work. Instead, persist the completed-agent manifest and reload only unfinished dependent tasks. A verified task manifest can distinguish finished specialist work from pending dependent steps after interruption.

Resuming a compacted session should preserve verified progress. Restarting the whole workspace discards verified work that a targeted summary could preserve. A Claude Code session has accumulated thousands of lines of successful test logs. Instead, compact conversation while retaining verified decisions and next steps.

Repeated low-value output displaces important decisions. Success logs can be reproduced and do not warrant permanent occupation of reasoning context. A Claude Code session has accumulated thousands of lines of successful test logs. Instead, compact conversation while retaining verified decisions and next steps.

A smaller history without essential state is unsafe. Removing constraints during compaction loses the accepted plan and approval boundaries. A Claude Code session has accumulated thousands of lines of successful test logs. Instead, compact conversation while retaining verified decisions and next steps.

Historical references do not justify new implementation. Restoring code solely to satisfy stale notes could reintroduce obsolete behavior. An agent cites a function that was deleted during a migration. Instead, reinspect affected paths before claiming current architecture. A source citation must refer to a file and function that still exists in the current revision.

The migration removed that code path. A deleted function cannot substantiate a current claim about how the migrated code executes. A source citation must refer to a file and function that still exists in the current revision. An agent cites a function that was deleted during a migration.

Repository evidence must reflect the current revision. Prior documentation approval does not prove the current repository still has the same path. A source citation must refer to a file and function that still exists in the current revision. Instead, reinspect affected paths before claiming current architecture.

Exhaustive reading wastes context and time. Reading everything before locating entry points consumes context with irrelevant implementation detail. A developer reads every repository file without first locating entry points. Instead, find key packages and call paths, then inspect only relevant modules.

Naming gives incomplete call-flow evidence. Directory labels are hints, not verified edges linking a request to its handler. A developer reads every repository file without first locating entry points. Instead, find key packages and call paths, then inspect only relevant modules.

An ungrounded patch can affect the wrong module. Changing a likely file without ownership confirmation can break the wrong service. Reading all files indiscriminately uses context and tool budget without identifying the actual dependency chain. A developer reads every repository file without first locating entry points. Instead, find key packages and call paths, then inspect only relevant modules.

The finding cannot be located or tested reliably. A generic parser complaint cannot be reproduced without locating the source implementation. A code-navigation summary identifies a bug but drops filename and line reference. Instead, retain file path and location so the fix can be verified.

Stale pointers may direct remediation to wrong code. A line number from an old revision can now point to unrelated statements. A code-navigation summary identifies a bug but drops filename and line reference. Instead, retain file path and location so the fix can be verified.

A domain name is not an actionable code location. A broad domain name does not let an engineer inspect the allegedly defective function. An uncited code-navigation summary may be directionally helpful but cannot substantiate a specific line-level issue. Instead, retain file path and location so the fix can be verified.

Transient tool logs obscure stable service relationships. Transient build output changes frequently and should not displace durable architecture notes. Otherwise verbose logs drown out the facts needed to orient the next code investigation. Instead, persist architecture facts and prune routine tool output.

Key structural facts should outlive temporary logs. Removing service boundaries leaves future work without the validated system map. Otherwise verbose logs drown out the facts needed to orient the next code investigation. A long session contains repeated build output that obscures stable service boundaries.

A single log event cannot represent system structure. A single error line describes one event, not how the modules interact. Otherwise verbose logs drown out the facts needed to orient the next code investigation. Instead, persist architecture facts and prune routine tool output.

Structured summaries make integration and traceability clearer. Untyped prose obscures the separation between interface facts, unresolved risks and decisions. Specialists should return interfaces, risks, decisions and links to supporting documents rather than entire source dumps. Instead, request concise structured outputs with reference links.

The lead needs findings, not repeated raw source material. Four document transcripts multiply context cost without producing an integrated risk summary. Specialists should return interfaces, risks, decisions and links to supporting documents rather than entire source dumps. Four specialists send raw document text when the lead needs only interfaces and risks.

Missing pointers prevent source verification. A conclusion without source IDs cannot be independently verified by the coordinator. Specialists should return interfaces, risks, decisions and links to supporting documents rather than entire source dumps. Instead, request concise structured outputs with reference links.

The verified manifest already records successful work. The task manifest is the evidence that previous specialist results remain completed. After resuming, the coordinator reruns tasks already completed by an earlier session. Instead, reload a verified manifest of completed tasks and pending dependencies.

A restarted coordinator has not made pending work disappear. Resuming the coordinator does not automatically execute dependencies that were left pending. After resuming, the coordinator reruns tasks already completed by an earlier session. Instead, reload a verified manifest of completed tasks and pending dependencies.

Lifecycle state must be read from verified evidence. Marking every task successful ignores failed or absent completion receipts. After resuming, the coordinator reruns tasks already completed by an earlier session. Instead, reload a verified manifest of completed tasks and pending dependencies.
