Your permission mode affects whether Claude asks before acting, but it does not replace your responsibility to review the code, commands, and test results.
1. Check which permission mode is active
Claude Code does not use one universal approval flow. Anthropic’s security documentation and CLI reference describe different behaviors by permission mode; the active mode, settings, version, and interface can affect what Claude may do without asking.

| Mode or setting | What it means for review |
|---|---|
| Manual mode | Anthropic describes this as read-only by default, with prompts before edits, tests, and commands. Review each requested action before approving it. |
| Auto mode | A separate classifier reviews actions and blocks those it judges unsafe. This is an additional safeguard, not a substitute for reviewing changes yourself. |
| Accept Edits mode | Anthropic says file edits and a fixed set of filesystem Bash commands for paths in the working directory are auto-approved. Other Bash commands and paths outside that scope still prompt. |
--dangerously-skip-permissions |
The CLI reference documents this flag as skipping permission prompts. Do not treat the absence of a prompt as evidence that an action is safe. |
Check the session’s mode and project settings before you begin. In particular, do not assume that a prompt will appear for every edit or command: that depends on the mode and its scope.
2. Inspect the proposed changes before applying them
Read the actual diff, not just Claude’s summary. Confirm which files are being changed and whether the edits match the requested task. Pay particular attention to files that could affect security, credentials, deployment, or tests. Anthropic specifically advises checking changes to critical files; these examples are practical categories to consider, not a complete list supplied by Anthropic.
#1 Best Overall
- Look for unexpected files, broad rewrites, or changes outside the intended project area.
- Check that credentials, tokens, and other secrets are not exposed or replaced with unsafe defaults.
- Verify that tests still cover the behavior being changed.
- If you cannot explain what a consequential edit does, pause and ask for a narrower explanation or proposal.
Anthropic puts the responsibility plainly: “You’re responsible for reviewing proposed code and commands for safety before approval.”
3. Read every suggested command before approving it
A command can have effects beyond the files visible in a code diff. Before running one, understand its working directory, what it reads or writes, whether it accesses the network, and whether it executes code or deletes or overwrites data. Anthropic advises reviewing suggested commands; in Manual mode, web-fetching shell commands such as curl and wget are not auto-approved by default.
- Be cautious with commands that download and immediately execute a script, remove files, change permissions, or overwrite configuration.
- Check whether a command contacts an external service or sends project data outside your environment.
- Do not pipe untrusted content directly to Claude. Review and isolate it first.
- For scripts or tool calls involving external web services, consider using an isolated virtual machine.
Permission prompts and operating-system isolation solve different problems. Anthropic notes that Claude’s file tools have a working-directory boundary in Manual mode, but an approved Bash command can still write anywhere the user account can. Sandboxing can add filesystem and network isolation for Bash commands; it is not the same as a permission prompt.

4. Apply changes in small, testable increments
Ask Claude to make one bounded change at a time rather than approving a large, difficult-to-audit rewrite. Anthropic’s common workflows separate recommendations, application, and test verification, and advise small increments and backward compatibility where needed.
- Ask for a recommendation or plan before implementation when the change is consequential or unclear.
- Approve a limited set of edits, then inspect the resulting diff.
- Run the relevant tests before asking for the next change.
- Where compatibility matters, check that existing behavior and interfaces remain supported.
This separation makes it easier to identify which change caused a problem and to undo or revise it without losing unrelated work.

Run the tests relevant to the modified behavior, and inspect failures rather than assuming generated code is correct. Then review the final diff for unintended files, incomplete changes, or command effects that are not obvious from the summary. For a Claude-generated pull request, Anthropic recommends reviewing the PR and asking Claude to call out possible risks or considerations; use that as another review aid, not as a replacement for your own inspection.
Rank #4
Anthropic’s documentation is live and may change as Claude Code evolves. Confirm the current permission behavior in the security documentation and CLI reference when relying on a particular mode or flag.
