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.\n- OpenAI Agents API (87): Project keys with restricted per-endpoint permissions, service accounts and workload identity, per the openai-api listing; we didn't confirm a key can be limited to /v1/agents (27 of 30). Automatic review for approvals, a sandbox network restricted to a host allowlist, vaults for secrets and a sandbox security guide (17 of 20). The agent reads web pages, MCP results and browser content; the sandbox security guide and approval flow are the mitigations, with no prompt-injection guide of its own found (8 of 15). Tracing, observability and usage per session and admin audit logs (15). SOC 2 Type 2, ISO 27001 family, Bugcrowd bounty and a disclosure policy, per the openai-api listing (20). Not ZDR-eligible and US residency only, recorded under transparency. 27 + 17 + 8 + 15 + 20 = 87.\n\n### Schema \u0026 documentation: OpenAI Agents API +16\n\n- 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).\n- OpenAI Agents API (88): The reference is linked from the overview and the SDKs carry beta.agents types; we didn't confirm /agents/sessions in OpenAI's public OpenAPI file, so 15 of 25. llms.txt with every Agents API page and Markdown twins (10). The overview, architecture page and the agents guide that compares the Agents API, Agents SDK and Responses API say when to use it (20). Typed configuration with enumerated container sizes, network modes and environment types (13 of 15). Examples in six languages and an errors page with codes per HTTP status, turn and session (15). Dated changelog entries and a versioned beta header (15). 15 + 10 + 20 + 13 + 15 + 15 = 88.\n\n### Transparency \u0026 trust: OpenAI Agents API +11\n\n- 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.\n- OpenAI Agents API (85): Closed service with clear terms, Apache-2.0 SDKs (15). Session state retained until deleted, deletable sessions and artifacts, not ZDR-eligible, US residency only, and the data-controls guide agrees; no retention period for artifacts after a sandbox expires (25 of 30). Dated deprecation notices with minimum periods for GA models; a beta API can change faster (15 of 20). Subprocessors and processing countries listed, per the openai-api listing (20). 15 + 25 + 15 + 20 = 75.\n\n### Payments \u0026 pricing: GitHub Copilot CLI +10\n\n- 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.\n- OpenAI Agents API (30): No machine payment protocol (0). Model, tool and container prices published without a login, and no fee for the API itself (20). The Free tier reading of the openai-api listing, half (10). Sign-up in a browser (0). 0 + 20 + 10 + 0 = 30.\n\n### Maintenance \u0026 community: OpenAI Agents API +10\n\n- GitHub Copilot CLI (77): 1.0.105 on 27 October 2026 per the changelog and its tag, 8 days before this check. Tags 1.0.106-1 to 1.0.106-8 (30 October) are pre-releases with no changelog entry and don't count (30). 25 dated releases from 1.0.79 (10 August) to 1.0.105 (27 October) in the 90 days from 6 August (20). Issues are labelled and triaged, with automation for stale and unanswered reports, though about 1,900 stay open, per the 1 October check (14). An SDK the changelog keeps updating (session APIs, MCP management, OAuth tokens), languages unchecked (10). Closed source and a bundled npm build, so no CI or dependency health to read (3). 30+20+14+10+3 = 77.\n- OpenAI Agents API (87): Closed API. Last dated change 16 October 2026, Ultrafast mode and document skills (30). Four dated changelog entries in the 57 days since release, 10 September, 29 September, 9 October and 16 October (20). Changelog and help centre, as the openai-api listing reads them (12 of 15). Official SDKs carry beta.agents (15). SDK CI, per the openai-api listing (10). 30 + 20 + 12 + 15 + 10 = 87.\n\n### Agent ergonomics: OpenAI Agents API +8\n\n- 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).\n- OpenAI Agents API (80): Read as an API an agent drives. Context is compacted automatically, and session budgets and streamed events keep output sized (20 of 25). Sessions can be listed, continued and steered, events streamed or sent by webhook, artifacts fetched (15 of 20). Actionable error codes with recovery steps (20). No idempotency key; a documented check-then-retry procedure (10 of 20). One session call with defaults (medium sandbox, network enabled), SDKs in five languages (15). 20 + 15 + 20 + 10 + 15 = 80.\n\n## Score by category\n\n| Category | Weight | GitHub Copilot CLI | OpenAI Agents API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 55 | 60 | OpenAI Agents API +5 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 72 | 88 | OpenAI Agents API +16 |\n| Agent ergonomics | 13% (16.2 this run) | 72 | 80 | OpenAI Agents API +8 |\n| Security \u0026 auth | 14% (17.5 this run) | 65 | 87 | OpenAI Agents API +22 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 40 | 30 | GitHub Copilot CLI +10 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 77 | 87 | OpenAI Agents API +10 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 74 | 85 | OpenAI Agents API +11 |\n| Negative events | ≤15 | -8 | 0 | |\n| **Total** | | **56 · C** | **73.3 · BB** | |\n\n## Facts side by side\n\n| Fact | GitHub Copilot CLI | OpenAI Agents API |\n| --- | --- | --- |\n| Kind | Agent harness | HTTP API |\n| Vendor | GitHub | OpenAI |\n| Hosted endpoint | no (local only) | `https://api.openai.com/v1/agents/sessions` |\n| Transports | | https |\n| Auth | OAuth or key | API key |\n| Pricing | Freemium | Pay per use |\n| x402 | no | no |\n| Licence | Proprietary, under the licence in the repository's `LICENSE.md`.

Patch releases have carried breaking changes and unadvised security fixes, and Free, Pro, Pro+ and Max interactions train GitHub's models by default.\n\n**OpenAI Agents API.** OpenAI's hosted agent runtime, the Codex harness behind one session call, with MCP, functions, web search, computer use, subagents and sandboxes on OpenAI or your own infrastructure. Documentation, errors and SDKs are thorough. It's still public beta, can't use Zero Data Retention and keeps data in the United States only.\n\n## Before you call either\n\n### GitHub Copilot CLI\n\n1. Pass `--deny-tool` for anything destructive. It wins over `--allow-all-tools` and `--allow-tool`\n2. Turn on the sandbox with `/sandbox enable` or `--sandbox`. It's off by default\n3. Pin the CLI version in scripts. Patch releases have removed flags such as `--no-remote`\n4. Add `--disable-client-telemetry` if client telemetry shouldn't leave the machine\n5. Move off Claude Opus 4.8, Claude Opus 5 and GPT-5.6 Terra before 16 November 2026\n\n### OpenAI Agents API\n\n1. POST https://api.openai.com/v1/agents/sessions with a project key and the header OpenAI-Beta: agents=v1, or use client.beta.agents in the SDKs\n2. Before retrying, retrieve the session and turn and check which actions completed, since there's no idempotency key\n3. Set the sandbox network to restricted with an allowlist of up to 100 hosts when the agent doesn't need the open web\n4. Save files from /workspace/outputs before deleting a session; no retention period is stated for artifacts\n5. Don't send data that needs Zero Data Retention or non-US residency; the Agents API supports neither\n\n## Questions\n\n### Which is better for AI agents, GitHub Copilot CLI or OpenAI Agents API?\n\nOpenAI Agents API scores 73.3 (BB) on agent readiness against GitHub Copilot CLI's 56 (C), and leads in 6 of 7 scored categories.
