Anthropic CCAR-P Based on Real Exam Environment

Project-scope configuration is appropriate for shared MCP definitions, permissions, hooks, and other repository-specific behavior that every team member should receive consistently. Managed configuration complements this by enforcing organization-wide security and compliance requirements that individual developers cannot override. Together, these mechanisms separate collaborative project configuration from centrally controlled policy. Editor themes are personal preferences and do not materially establish a secure environment. Allowing each engineer to select an arbitrary model can undermine consistency when model choice affects behavior, cost, or approved-use requirements. Storing a shared API key in a committed project file is a serious credential-management failure. Claude Code documentation identifies .claude/settings.json as the shared project file and managed settings as the highest-precedence organizational policy layer.

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

Implementation-ready documentation must provide both executable specifications and preserved architectural reasoning. Option A supplies the contracts an implementation team needs to build components independently: configuration schemas, accepted inputs, produced outputs, validation requirements, and integration boundaries. These details prevent teams from inventing incompatible assumptions about data structures, tool behavior, error handling, or component ownership.

Option B complements the technical contracts with a decision log. Recording the selected design, underlying constraints, alternatives considered, and reasons for rejection enables implementers to distinguish deliberate architectural decisions from accidental omissions. It also prevents previously rejected approaches from being reintroduced without new evidence.

A high-level business narrative in Option C may explain purpose but cannot direct component-level implementation. Contact information in Option D provides an escalation route, but documentation is not sufficient if routine progress still depends on the architect’s availability. Option E records activity rather than a decision; a model list without the selected model and selection rationale leaves critical cost, latency, capability, and evaluation assumptions unresolved.

A strong handoff package should permit implementation, testing, and support teams to proceed while escalating only genuinely new architectural questions.

Federated authorship allows each domain team to maintain the procedural knowledge it understands while preserving organization-wide trust through a central publication gate. Team authors can update coding standards, review practices, and postmortem procedures without waiting for a single platform group to write every change. Central reviewers can validate ownership, security, tool permissions, duplication, versioning, testing evidence, and compliance before publication. Per-developer or fully decentralized publication creates inconsistent and potentially unsafe Skills. Fully centralized authorship becomes a scalability bottleneck and separates content maintenance from domain expertise. Anthropic describes Skills as packages of instructions, scripts, and resources and warns that repository Skills may grant broad tool access, making formal review essential. Claude Code Skills

Option D applies three complementary controls. First, a read-only database credential creates an authorization boundary outside the model; prompt instructions alone cannot convert that credential into write access. Second, restricting the subagent’s tool list reduces capability exposure by preventing the agent from selecting unrelated or unnecessarily privileged operations. Third, explicit human confirmation creates a deliberate approval gate before any exceptional data-changing action is executed.

This is defense in depth. If Claude misinterprets a request or processes malicious instructions from untrusted content, the restricted credential and tool configuration limit the available action surface. Human review then protects operations with potentially irreversible production consequences. Logging and audit trails should remain enabled to record the actor, request, tool call, approval, affected records, and outcome.

Anthropic documents that Claude Code begins with read-only permissions in Manual mode and requests approval for actions that modify the environment. Its permission system also supports granular allow, ask, and deny controls for MCP tools and subagents. Claude Code Security, Configure Permissions

Options A and B eliminate least privilege and approval boundaries. Option C removes essential detection and forensic evidence.
