Safe Claude Code Permissions Settings for Running Commands Without Repeated Prompts

Reduce prompts without removing the safety boundary

Claude Code asks for confirmation before actions that can affect your files, shell, network, or external services. That prompt can feel repetitive during development, but turning everything off is not the same as improving workflow.

The safer approach is to configure permissions so low-risk commands can run without repeated prompts, while destructive or external-state-changing actions still require confirmation or are blocked.

This article reflects the Claude Code settings and permissions model as of July 2026. For the official reference, see:

Where settings live

Claude Code settings are hierarchical.

The precedence order is:

Managed > CLI arguments > Local > Project > User

Most settings are overridden by the higher-priority scope. Permission rules are different: they are merged across scopes. A deny rule from any scope remains important even if another scope contains an allow rule.

allow / ask / deny

Claude Code permissions use three rule lists:

• allow: run without asking when matched
• ask: ask for confirmation when matched
• deny: block when matched

Rules are evaluated in this order:

deny -> ask -> allow

The first matching result wins. Specificity does not override that order. For example, if deny contains Bash(aws *), adding Bash(aws s3 ls) to allow will not make it pass.

A safer starting point

Use valid JSON in the actual file. JSON does not allow comments.

{
  "$schema": "https://json.schemastore.org/claude-code-settings.json",
  "permissions": {
    "allow": [
      "Bash(git status)",
      "Bash(git diff *)",
      "Bash(git log *)",
      "Bash(rg *)",
      "Bash(npm run lint)",
      "Bash(npm run test *)",
      "WebFetch(domain:docs.anthropic.com)",
      "WebFetch(domain:github.com)"
    ],
    "ask": [
      "Bash(git push *)",
      "Bash(npm install *)",
      "Bash(gh *)"
    ],
    "deny": [
      "Read(./.env)",
      "Read(./.env.*)",
      "Read(./secrets/**)",
      "Bash(curl *)",
      "Bash(wget *)"
    ]
  }
}

Treat npm run lint and npm run test * as examples only when your project scripts are known and safe. Package scripts can execute arbitrary code, so avoid broad rules such as Bash(npm *).

What not to allow

Do not add broad allow rules like these:

• Bash or Bash(*)
• Bash(git *)
• Bash(npm *), Bash(node *), Bash(python *), Bash(make *)
• Bash(curl *), Bash(wget *)
• Bash(vercel *), Bash(gh *), Bash(aws *), Bash(kubectl *), Bash(terraform *)
• Bash(rm *), Bash(chmod *), Bash(chown *), Bash(sudo *)

These are not small efficiency settings. They can remove the safety boundary around destructive operations, production writes, credential exposure, downloads, or external side effects.

Team settings

Use .claude/settings.json for team-shared policy:

• repository-specific safe commands
• required denials for secrets
• shared WebFetch domains
• hooks or other project conventions

Use .claude/settings.local.json for personal or machine-specific settings:

• local experiments
• editor preferences
• personal paths
• commands that should not be shared with the team

Claude Code ignores .claude/settings.local.json in git when it creates the file. If you create it manually, add it to .gitignore.

Hot reload and model settings

Claude Code reloads many settings while a session is running, including permissions and hooks. Some settings are read at startup. For model changes during a session, use /model.

This article intentionally keeps model out of the permissions examples. Model selection is a separate concern, and the best choice depends on your plan, cost, latency, and task type.

Avoid bypass permissions as normal operation

bypassPermissions and --dangerously-skip-permissions are not normal development defaults. If you use them at all, keep them to isolated environments such as containers or VMs that can be safely discarded.

Bash(*) is not "more efficient permissions." It is removing the safety boundary.

Summary

Claude Code permissions are useful when you make them narrow.

• Allow low-risk, repeatable commands.
• Ask before external writes or dependency changes.
• Deny secret reads and risky network commands.
• Share project rules in .claude/settings.json.
• Keep personal overrides in .claude/settings.local.json.

If you use Claude Code only as a personal efficiency tool, permissions reduce friction. If you use it as part of an AI employee workflow, permissions become an operational boundary: who can do what, under which project rules, and where human confirmation remains necessary.
