Verdicts

GitHub Copilot CLI

Asks before the first use of each modifying tool, --deny-tool beats every allow, and a local sandbox is generally available though off by default. Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026.

Rovo Dev CLI

Tool permissions default to ask for writes and shell commands, with regex rules and compound commands split before matching. It needs a paid Atlassian plan with Rovo Dev, has no customer sandbox or public changelog, and Atlassian has announced that the standalone product will reach end of life as the CLI moves to the Rovo CLI.

Before you call either

GitHub Copilot CLI

  1. Pass --deny-tool for anything destructive. It wins over --allow-all-tools and --allow-tool
  2. Turn on the sandbox with /sandbox enable or --sandbox. It's off by default
  3. Turn off model training in Copilot settings on Free, Pro, Pro+ and Max. It's on by default since 24 April 2026
  4. Move off Claude Opus 4.8, Claude Opus 5 and GPT-5.6 Terra before 16 November 2026
  5. Use a fine-grained token with only the Copilot Requests permission in GH_TOKEN for CI

Rovo Dev CLI

  1. Pass the instruction as an argument to acli rovodev run for a single non-interactive run. No JSON output flag or exit codes are documented
  2. Use acli rovodev serve <port> and stream /v3/stream_chat?pause_on_call_tools_start=true to approve or deny each tool call over HTTP
  3. Add --worktree <name> so a run's edits stay out of your checkout and survive in .rovodev/worktrees/<name>
  4. Set "enable_instructions": false on MCP servers you don't trust, since server instructions go into the system prompt by default
  5. Check /usage before long runs. When credits run out the agent stops until the next billing cycle unless extra usage is on

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.
