Anthropic CCAR-F Exam - Topic 2 Question 8 Discussion

Question

You are using Claude Code to accelerate software development. Your team uses it for code generation, refactoring, debugging, and documentation. You need to integrate it into your development workflow with custom slash commands, CLAUDE.md configurations, and understand when to use plan mode vs direct execution.

Your team has three requirements for Claude Code's behavior in your project:

Claude must never modify files in the db/migrations/ directory.

Claude should prefer your custom logging module over console.log.

All TypeScript files must be auto-formatted with Prettier after every edit.

All three are currently written as instructions in your project's CLAUDE.md. During a complex refactoring session, a developer discovers that Claude edited a migration file, violating requirement #1.

How should you restructure these requirements across Claude Code's configuration mechanisms?

Elouise · Accepted Answer

D) Add Edit(./db/migrations/**) to permissions.deny in the project settings, keep the logging preference in CLAUDE.md, and add a PostToolUse hook to run Prettier after TypeScript edits.

Elouise · Answer

A) Move all three requirements into .claude/rules/ as path-scoped rules: one targeting db/migrations/** that forbids editing those files, and others targeting **/*.ts for the logging convention and formatting instruction.

Elouise · Answer

B) Configure hooks for all three: a PreToolUse hook script that blocks Edit calls targeting db/migrations/, a PreToolUse hook script that adds logging convention context before edits, and a PostToolUse hook that runs Prettier after TypeScript edits.

Elouise · Answer

C) Rewrite all three requirements in CLAUDE.md using stronger directive language and add few-shot examples that demonstrate Claude refusing to edit migration files and running Prettier after edits.
