Which one, for what

Gemini CLI BB

Good for Developers and CI jobs that want an open-source harness with a free tier and documented headless output.

Ahead on

  • Reliability, 71 against 66
  • Schema & documentation, 93 against 81
  • Agent ergonomics, 78 against 70
  • Maintenance & community, 88 against 78
  • Transparency & trust, 87 against 65

Also in its favour

  • Agent-ready, a grade of BB or better

Watch for

Sandboxing is off by default, and the default macOS profile allows network

Paperclip C

Good for Someone running several coding or operations agents who wants one place for tasks, budgets, approvals and history across harnesses.

Ahead on

  • Payments & pricing, 60 against 40

Watch for

claude_local defaults dangerouslySkipPermissions to true and codex_local defaults to bypassing approvals and the sandbox, with agents running on the host

Verdicts

Gemini CLI

Apache-2.0, CI passing on main, and 583 open issues with priority labels. Sandboxing is off by default, and the default macOS profile allows network.

Paperclip

Board approvals, budgets with a hard stop and an activity log sit above whichever harnesses do the work, and eleven stable versions shipped in 90 days. The Claude Code and Codex adapters skip permission prompts and the sandbox by default, and twelve security advisories, five of them critical, have been published since April 2026.

Before you call either

Gemini CLI

  1. Set GEMINI_TRUST_WORKSPACE to true only for trusted inputs in CI. Since 0.39.1 headless mode doesn't trust a folder on its own
  2. Turn on the sandbox with -s or tools.sandbox, and pick a proxied Seatbelt profile on macOS to cut network
  3. Set privacy.usageStatisticsEnabled to false to stop usage statistics
  4. Read the exit code. 42 is bad input and 53 is the turn limit
  5. Use --output-format stream-json to get tool calls and results as JSONL events

Paperclip

  1. Set PAPERCLIP_TELEMETRY_DISABLED=1 or DO_NOT_TRACK=1 before the first start. Telemetry is on by default
  2. Set dangerouslySkipPermissions and dangerouslyBypassApprovalsAndSandbox to false on agents that read untrusted input, or run them in a sandbox provider
  3. Install with Node.js 24.11 or newer, and install and sign in to each harness CLI on the host first. Paperclip assumes they are there
  4. Use --bind lan or --bind tailnet at onboarding for anything beyond one machine. The default local_trusted mode treats every request as the board admin
  5. Treat 409 on task checkout as owned by another agent and pick different work. The API docs say not to retry

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.
