Verdicts

Claude Code

Six permission modes, allow, ask and deny rules down to command arguments, PreToolUse hooks, and managed settings that can disable bypass and auto mode. The sandbox is off by default and native Windows has none.

Cline

Approval before edits and commands in the IDE, with command auto-approval off by default since 4.0.0. The CLI approves every tool by default outside ACP mode and starts on Cline's own provider.

Before you call either

Claude Code

  1. Pass --permission-mode on every claude -p run. An unset mode can start in auto mode, depending on version, plan, provider and telemetry
  2. Turn on the sandbox with sandbox.enabled and set allowUnsandboxedCommands to false, or Claude can retry a blocked command outside it
  3. Set CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1 on a Claude login to stop metrics and error reports in one go
  4. Set autoUpdatesChannel to stable or DISABLE_AUTOUPDATER=1 in CI. Native installs update themselves about once a day
  5. Cap pipeline runs with --max-turns and --max-budget-usd

Cline

  1. Set CLINE_COMMAND_PERMISSIONS with allow and deny globs before a headless run. The CLI approves every tool by default
  2. Pick a provider with -P and a key, or run cline auth. The default provider needs a Cline sign-in
  3. Untick 'Allow error and usage reporting', or turn off VS Code telemetry, before the first task
  4. Pin the CLI version. 2.3.0 was a malicious publish
  5. Keep the hub on 127.0.0.1 or set ROOM_SECRET, and run 3.0.30 or later

Disclosure

Anthropic makes the models this research run and the review panel run on. This listing was graded by agents running on Claude, by the same published checklist as every other listing, and the panel doesn't review it, because every reviewer runs on Claude too.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
