GitHub Copilot CLI vs Traycer

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.

Traycer 42

Harness reading. Code is processed in memory and not used for training, but Privacy Mode is opt-in for individuals, prompts may be logged with it off, and Sentry and PostHog 'may be enabled in release builds' (10 of 30). No approval model described in the README (8 of 20). No prompt-injection guidance (5). No audit log found (5). SECURITY.md, CodeQL, Scorecard and secret scanning (14 of 20). 10 + 8 + 5 + 5 + 14 = 42.

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.

Traycer 60

MIT (30). README privacy section and a linked privacy policy (not read) (18 of 30). CHANGELOG.md, no deprecation policy (10). Analytics described as 'may be enabled', with no opt-out given in the README (8 of 20). 30 + 18 + 10 + 8 = 66.

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.

Traycer 65

Local software. Builds for macOS, Linux and Windows, and package-manager publishing workflows (20). test.yml, CodeQL, OpenSSF Scorecard and secret scanning run 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). Host 1.5.3 (15). 20 + 15 + 0 + 15 + 15 = 65.

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.

Traycer 30

Scored on the paid option, Traycer's own inference subscription, whose price wasn't read (0 of 20). No protocol (0). Bring-your-own-agent use is free (20). Accounts for sync and teams weren't checked, half (10). 0 + 0 + 20 + 10 = 30.

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).

Traycer 65

Harness reading. Mintlify docs, a protocol package and a CLI (65).

GitHub Copilot CLI 72

Framework reading, adapted to a harness driven by a pipeline. --available-tools and --excluded-tools shape the tool list and --deny-tool removes tools, and MCP tool discovery recovers without a restart (20). --max-autopilot-continues caps autopilot, and a turn timeout applies to background work in -p (15). JSON output, and a 2026 release replaced a misleading auth error with the real cause (12). --resume and --continue, and permission prompts survive a resumed session (15). An SDK exists, per the changelog, but we didn't check its languages, and a headless run needs explicit allow flags to do anything (10).

Traycer 65

Harness reading. Model switching within an agent, agent-to-agent loops, a CLI and cross-device sync (65).
