Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Payments & pricing Paseo +20

GitHub Copilot CLI 40

Harness reading of the published rubric. No payment protocol (0). Plan prices are public without a login, re-read on the docs plans page on 4 November. Pro $10, Pro+ $39, Max $100 a month, Business $19 and Enterprise $39 a seat, with usage past an organisation's pool at $0.01 per AI credit (20). Copilot Free includes the CLI with an allowance of AI credits and auto model selection only, and no card per the 2 October check (20). A person signs in to GitHub or creates the token (0). 0+20+20+0 = 40.

Paseo 60

Free self-hosted software with nothing to buy, so 0 for a protocol and 20 each for public pricing, a free tier and onboarding with no sign-up, 60.

Schema & documentation GitHub Copilot CLI +7

GitHub Copilot CLI 72

Framework reading. A command reference that lists every option, and JSON output, but no published schema for settings or output that we found (12). docs.github.com/llms.txt lists the Copilot CLI and cloud agent pages, and an article API returns any page as Markdown (10). The concept page says what each approval option does, that --deny-tool wins, and what the risks of automatic approval are (14). Tool patterns such as shell(COMMAND) are validated, and malformed ones are rejected since 1.0.x (10). Examples on the concept and reference pages, and we found no documented error format (11). A dated changelog per release with breaking changes marked (15).

Paseo 65

Harness reading. Public docs, a CLI and plugin examples in the repository (65).

Security & auth GitHub Copilot CLI +7

GitHub Copilot CLI 65

Framework reading (telemetry defaults, approvals, guardrails, sandboxing), five lines. Since 1.0.100 (19 October 2026) --disable-client-telemetry turns off the telemetry the CLI sends, which the command reference says doesn't affect server-side telemetry. Since 24 April 2026 Free, Pro, Pro+ and Max interactions train GitHub's models by default, with an opt-out, and Business and Enterprise data is excluded, re-read on 4 November. A fine-grained token with only the Copilot Requests permission works for CI (16). Asks before the first use of each modifying tool, deny rules that beat --allow-all-tools, URL and path permissions, trusted directories and enterprise managed settings. Local sandboxing is generally available since 1.0.93 (7 October 2026) and off by default, enterprises can require it fail-closed, and since 1.0.100 the sandbox allows local network access by default. Assisted Permissions, where a model approves requests it judges safe, left experimental mode in 1.0.104. The CLI still can't enforce two organisation MCP policies (17). The sandbox proxy filters hosts, sandboxed shells withhold GITHUB_TOKEN since 1.0.92, and content exclusion applies, but we found no prompt-injection guidance for the CLI (9). OpenTelemetry export with GenAI spans, opt-in, with enterprise capture controls since 12 October, and session logs (13). Two advisories with CVEs in 2026 and none since on OSV, re-read on 4 November, but no SECURITY.md in the repository and an expired security.txt on github.com per the 26 September check, which the proxy still refuses. We didn't check GitHub's bug bounty (10). SOC 2 isn't scored on the framework reading. 16+17+9+13+10 = 65.

Paseo 58

Harness reading. The README says no telemetry, tracking or forced log-ins (30 of 30). Worktree per agent, on your own machine (10 of 20). No prompt-injection guidance (5). No audit log (5). SECURITY.md (8). 30 + 10 + 5 + 5 + 8 = 58.

Transparency & trust GitHub Copilot CLI +6

GitHub Copilot CLI 74

Proprietary licence with clear terms for running and redistributing (15). The data-use page dates the training change (24 April 2026), says which plans it covers and how to opt out, and says Business and Enterprise data isn't used, re-read on 4 November, but we didn't find retention periods for CLI sessions (18). On 15 October 2026 GitHub gave dated notice that Claude Opus 4.8, Claude Opus 5 and GPT-5.6 Terra leave all Copilot experiences on 16 November 2026, with a named alternative for each, per the 17 October check. Breaking changes are mostly marked in a dated changelog. There's no written deprecation policy or notice period, the same reading as openai-codex and gemini-cli (15). The command reference now lists --disable-client-telemetry, added in 1.0.100 on 19 October, so client telemetry is disclosed with an opt-out, but no page says what it sends. OpenTelemetry export is documented and opt-in (12). 15+18+15+12 = 60.

Paseo 68

Apache 2.0 for everything but third-party components (30). No telemetry and agents run on your machine (22 of 30). CHANGELOG.md, no deprecation policy (10). States no telemetry (20). 30 + 22 + 10 + 20 = 82.

Reliability GitHub Copilot CLI +5

GitHub Copilot CLI 55

Local-package reading. npm, Homebrew, WinGet and an install script for Linux, macOS and Windows, with PowerShell 6 or newer named for Windows, though the npm package declares no engines, per the 17 October check (20). No public CI or test suite, since the source isn't published, and the repository holds only the README, licence, changelog, install script and a container folder, per a clone on 4 November (0). About 1,900 open issues and 28 open pull requests, labelled by area and platform with a triage label and no-response automation, per the 1 October check, not re-read on 4 November (12). A dated changelog for every release, with breaking changes marked BREAKING, though they ship in 1.0.x patch versions, and 1.0.103 removed the --no-remote flag without the label (8). 1.0 since March 2026, at 1.0.105 on 27 October per the changelog and tag (15). Same reading as Claude Code and Cursor CLI, which are also closed source. 20+0+12+8+15 = 55.

Paseo 50

Local software. Desktop builds, an Android APK, a Docker image and a Nix package (20). ci.yml on the repository; pass state not read (15). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). CHANGELOG.md (15). Version 0.15.3 (0). 20 + 15 + 0 + 15 + 0 = 50.

How the scores have moved

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. Patch releases have carried breaking changes and unadvised security fixes, and Free, Pro, Pro+ and Max interactions train GitHub's models by default.

Paseo

A self-hosted, open-source workspace for running many coding agents on your own machines, scriptable from the CLI and reachable from phone, web or desktop, with no telemetry or forced log-in. It's pre-1.0 and run largely by one maintainer.

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. Pin the CLI version in scripts. Patch releases have removed flags such as --no-remote
  4. Add --disable-client-telemetry if client telemetry shouldn't leave the machine
  5. Move off Claude Opus 4.8, Claude Opus 5 and GPT-5.6 Terra before 16 November 2026

Paseo

  1. Run the daemon on the machine that has your tools and credentials, and connect from the clients
  2. Script runs from the CLI for repeatable agent jobs

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.
