In this episode you will learn:

- That the CCA-F exam tests context management as a core skill focused on efficiency, cost, and accuracy.

- How to use the `@file` syntax for selective loading, which is the correct approach for exam scenarios over loading entire projects.

- To recognize that Claude automatically compacts conversation history when the context window is full, rather than simply losing data.

- When to use subagents to offload context-heavy tasks, keeping the main conversation clean and focused.

- To avoid the common exam trap of assuming more context is always better; the goal is a lean, high-signal context.

In this episode you will learn:

- The Plan-Apply pattern is a two-step workflow: the AI first proposes a plan, and the user then reviews and approves it before any code is written.

- This pattern's primary benefit is safety, as it separates the AI's reasoning from its actions with a mandatory human checkpoint.

- On the CCA-F exam, the Plan-Apply pattern is the best choice for scenarios involving high-risk, large, or complex code changes.

- Be aware of exam traps that test the trade-offs; for low-risk, speed-sensitive tasks, an incremental edit-and-verify pattern may be more suitable.

- Use the mnemonic "Look Before You Leap" to remember the safety-first principle of reviewing the plan before executing code changes.

In this episode you will learn:

- How subagents in Claude Code function as specialized, temporary agents for focused tasks.

- The primary benefit of using subagents: maintaining a clean, focused context in the main session by isolating intermediate work.

- An exam-style scenario demonstrating when to use a subagent, such as for complex, multi-step subtasks like API integration or database analysis.

- The critical trade-off tested on the CCA-F exam: gaining capability and context isolation at the cost of increased latency and coordination overhead.

- A common exam trap: confusing the thoroughness of subagents with overall speed and knowing not to use them for trivial requests.

In this episode you will learn:

- Claude Code's permission model defaults to 'ask-each-time' for consequential actions like file edits and shell commands.

- Permissions are the primary safety boundary, balancing productivity against the risk of unintended system changes.

- Exam questions are scenario-based, requiring you to 'right-size' permissions (allow, ask, deny) based on the task's risk level.

- A common exam trap is confusing the agent's application-level permission model with underlying user-level or IAM permissions.

- Use the mnemonic "Ask, Allow, or Deny to Match the Why" to select the appropriate permission level for a given scenario.

In this episode you will learn:

- What slash commands are and their role in standardizing workflows for the CCA-F exam.

- The critical difference between project-scoped commands for teams and user-scoped commands for individuals.

- How custom skills extend slash commands for more complex, multi-step processes.

- Why consistency and reusability are the key benefits tested on the exam.

- How to identify whether a scenario-based question calls for a project command, user command, or custom skill.

In this episode you will learn:

- That hooks are for deterministic policy enforcement, while prompts are only for probabilistic guidance.

- How `PreToolUse` hooks act as security guardrails by inspecting commands before they run and blocking them with a non-zero exit code.

- How `PostToolUse` hooks can automate workflows, like running a code formatter after any file edit.

- To avoid the common exam trap of confusing event-driven hooks with user-invoked custom commands.

- The critical difference in hook exit codes: exit 2 blocks an action, while exit 1 is a non-blocking error that allows the action to proceed.

In this episode you will learn:

- How CLAUDE.md provides persistent, project-specific instructions to the Claude AI agent.

- The difference between project-wide (root) and scoped (subdirectory) CLAUDE.md files for managing context in complex repositories.

- Why CLAUDE.md is the primary mechanism on the CCA-F exam for enforcing team coding standards and reducing repetitive corrections.

- Common exam traps, such as confusing CLAUDE.md with a README or overloading it with low-signal information.

- The importance of keeping the file concise, authoritative, and focused on high-level conventions and architecture.

In this episode you will learn:

- Claude Code is an agentic tool that directly manipulates files and the terminal, distinguishing it from a simple chat assistant.

- It is primarily configured using a CLAUDE.md file, which provides persistent project-specific context and instructions.

- Exam questions focus on its ability to perform multi-step tasks involving both file editing and shell command execution.

- A common exam trap is underestimating its direct integration; it functions like a junior developer, not a conversational consultant.

- For architects, Claude Code exemplifies key agentic patterns like planning, tool use, and subagent delegation, which are key topics on the CCA-F exam.
