Five agents with a read-only plan agent and bash allow and deny lists, a prompt for access outside the working directory, `outside_workdir = \"deny\"` (3.0.3) to refuse it outright, an admin `enable_auto_approve = false` (3.0.1) that forbids auto-approve, and `pre_tool` hooks that can deny calls. The default auto-approves file edits, and there's no sandbox on the host (13 of 20; 11 on 18 October, before the two settings). Project config, hooks and MCP servers load only from trusted folders, and `-p` needs `--trust` to load them. The safety page warns that smart-approve isn't a sandbox. No network egress control on the host, and MAI-2026-003 says injected instructions could trigger the bypassed commands (8 of 15). OpenTelemetry tracing is opt-in, with default, strict and no redaction, and each run can write a session journal and an export with the effective config. Managed admin config exists, and audit logs come with the Enterprise plan (13). SECURITY.md asks for private reports, security.txt is valid (expires 5 May 2027) and links a HackerOne form, and Mistral publishes dated advisories with CVEs, three to 2 November.

Markdown https://www.anchorterminal.com/tools/openai-agents-api.md · JSON https://www.anchorterminal.com/api/v1/tools/openai-agents-api.json\n- Best agent harnesses and coding agents: https://www.anchorterminal.com/best/agent-harnesses/index.md\n- All 1041 harnesses comparisons: https://www.anchorterminal.com/compare/agent-harnesses/index.md\n\n## Which one, for what\n\n### Mistral Vibe CLI (C)\n\nGood for: Developers and CI jobs that want an open-source harness tuned for Mistral models, with hard per-run budgets and an export file, or a local model with no account.\n\nAhead on:\n- Reliability, 69 against 60\n- Payments \u0026 pricing, 60 against 30\n\nAlso in its favour:\n- Free to start without a card\n- Open source\n\nWatch for: The default agent auto-approves file edits, and there's no sandbox on the host. Isolation needs the experimental `--agent-socket` server or a container\n\n### OpenAI Agents API (BB)\n\nGood for: Teams that want OpenAI to run the agent loop, with sandboxes, MCP tools and subagents, and are fine with a beta API, US-only data residency and no Zero Data Retention.\n\nAhead on:\n- Security \u0026 auth, 87 against 58\n- Maintenance \u0026 community, 87 against 73\n\nAlso in its favour:\n- Agent-ready, a grade of BB or better\n- A hosted endpoint, with nothing to install\n- No incidents deducted, where Mistral Vibe CLI loses 14 points for them\n\nWatch for: Public beta since 10 September 2026 behind the agents=v1 beta header, with no GA date\n\n\n## Why the edge\n\n### Payments \u0026 pricing: Mistral Vibe CLI +30\n\n- Mistral Vibe CLI (60): Harness reading of the published rubric, as for openai-codex and qwen-code. No payment protocol (0). Plan prices (Pro $14.99 a month, Team $24.99 a user a month) and per-token API prices for the default model ($1.5 and $7.5 per million) are public without a login (20). A Free plan includes limited coding sessions, and the docs document a fully offline set-up with a local model and no Mistral account. Whether the Free plan asks for a card wasn't checked (20). An agent can install the CLI and run it against a local OpenAI-compatible server with no sign-up, since a llama.cpp provider on 127.0.0.1:8080 is in the defaults (20). 0+20+20+20 = 60.\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### Security \u0026 auth: OpenAI Agents API +29\n\n- Mistral Vibe CLI (58): Framework reading (telemetry defaults, approvals, guardrails, sandboxing), five lines. Telemetry and crash reporting are on by default with an opt-out, and the source sends tool names, approval decisions, the model and file counts to api.mistral.ai only when a Mistral key is set. Telemetry also turns on GrowthBook experiments, and one of them (`vibe_cli_smart_approve_default`) can make smart-approve the default. Credentials are Mistral keys in an environment variable, a plaintext `~/.vibe/.env` or the keyring, workspace-scoped with optional expiry per the mistral-api listing, and MCP servers can use OAuth (12 of 30). Five agents with a read-only plan agent and bash allow and deny lists, a prompt for access outside the working directory, `outside_workdir = \"deny\"` (3.0.3) to refuse it outright, an admin `enable_auto_approve = false` (3.0.1) that forbids auto-approve, and `pre_tool` hooks that can deny calls. The default auto-approves file edits, and there's no sandbox on the host (13 of 20; 11 on 18 October, before the two settings). Project config, hooks and MCP servers load only from trusted folders, and `-p` needs `--trust` to load them. The safety page warns that smart-approve isn't a sandbox. No network egress control on the host, and MAI-2026-003 says injected instructions could trigger the bypassed commands (8 of 15). OpenTelemetry tracing is opt-in, with default, strict and no redaction, and each run can write a session journal and an export with the effective config. Managed admin config exists, and audit logs come with the Enterprise plan (13). SECURITY.md asks for private reports, security.txt is valid (expires 5 May 2027) and links a HackerOne form, and Mistral publishes dated advisories with CVEs, three to 2 November. No bounty terms or certification report were read, so 12, as mistral-api and mistral-voxtral-transcribe take on the same Mistral pages (14 on 18 October). 12+13+8+13+12 = 58.\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### Maintenance \u0026 community: OpenAI Agents API +14\n\n- Mistral Vibe CLI (73): 3.0.4 on 30 October 2026 (30). 21 release tags from 4 August to 2 November, 2.24.0 to 3.0.4, each with a dated changelog entry (20). The 18 October issue and pull request counts came from shields.io badges, a third-party copy of GitHub data this run bars, so they are struck. Response times couldn't be read. CONTRIBUTING.md says the project isn't accepting contributions, and the history is squashed release commits. Credit is for the dated changelog, the issue templates and the public advisory (8 of 25; 10 on 18 October with the counts). No SDK. `vibe-acp` is current in the ACP registry at 3.0.4 and the Homebrew formula is at 3.0.4 (8 of 15). Dependencies are pinned to exact versions, workflow actions are pinned by commit, and CI runs on main, but no Dependabot or Renovate config was found (7 of 10). 30+20+8+8+7 = 73.\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### Reliability: Mistral Vibe CLI +9\n\n- Mistral Vibe CLI (69): Local-package reading. PyPI, uv, pip, Homebrew at 3.0.4 and an install script, with Python 3.12 or later stated and UNIX the supported target (20). A public CI workflow on push and pull request to main runs pre-commit, the test suite and a build and install smoke matrix, but GitHub's pages and API were refused in this session, so whether main is passing is unchecked (15 of 25). The 18 October issue counts came from shields.io badges, a third-party copy of GitHub data this run bars, so they are struck. Every release has a Fixed section in the changelog, and how many open issues are crashes or regressions, and how fast they're answered, couldn't be read (10 of 25). The changelog states Keep a Changelog and semver and marks breaking changes, but the hooks rename shipped in minor 2.21.0, patch 2.11.1 changed the `-p` approval default, patch 2.26.1 removed the bundled local model, and patches 3.0.3 and 3.0.4 carry marked config, model and session breaks (9). 3.0.4, classified Production/Stable (15). 20+15+10+9+15 = 69.\n- OpenAI Agents API (60): Read as a hosted API. status.openai.com has an Agents component under APIs (20). Since release on 10 September (57 days, not 90), the feed names the Agents API in a degraded-performance incident on 14 September, the elevated errors across ChatGPT, Codex and the API on 29 September (the openai-api listing reads that one as a major, 17:52 to 23:14 UTC), computer use issues and degraded workspace agents on 6 and 7 October, degraded performance across the APIs for 22 minutes on 21 October, and overbilling for hosted containers on 19 September. One major, the rest minor (10). Rate limits come from the shared guide, published per tier and model with headers, and the errors page adds a Files API allowance on session creation (15). 429 and 503 guidance with Retry-After, capped backoff and a check-then-retry procedure for turns (15). The Scale Tier SLA in the openai-api listing isn't shown to cover a beta API (0). Public beta behind the agents=v1 header (0). 20 + 10 + 15 + 15 + 0 + 0 = 60.\n\n## Score by category\n\n| Category | Weight | Mistral Vibe CLI | OpenAI Agents API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 69 | 60 | Mistral Vibe CLI +9 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 85 | 88 | OpenAI Agents API +3 |\n| Agent ergonomics | 13% (16.2 this run) | 84 | 80 | Mistral Vibe CLI +4 |\n| Security \u0026 auth | 14% (17.5 this run) | 58 | 87 | OpenAI Agents API +29 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 60 | 30 | Mistral Vibe CLI +30 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 73 | 87 | OpenAI Agents API +14 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 81 | 85 | OpenAI Agents API +4 |\n| Negative events | ≤15 | -14 | 0 | |\n| **Total** | | **58.4 · C** | **73.3 · BB** | |\n\n## Facts side by side\n\n| Fact | Mistral Vibe CLI | OpenAI Agents API |\n| --- | --- | --- |\n| Kind | Agent harness | HTTP API |\n| Vendor | Mistral AI | 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 | Apache-2.0 | Proprietary hosted API under OpenAI's Services Agreement.

File edits are auto-approved by default, the host has no sandbox, telemetry is on by default, and patch releases 3.0.3 and 3.0.4 shipped marked breaking changes.\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### Mistral Vibe CLI\n\n1. Pass `--agent` on every `-p` run (`plan` is read-only). The default is `accept-edits`, and an experiment can switch it to `smart-approve`\n2. Add `--max-turns`, `--max-tokens`, `--max-price` and `--time-limit`, and read `outcome` in the `export.json` that `--output-dir` writes. Exit 3 means a limit or a refusal\n3. Run in a container or behind `--agent-socket` before using `--auto-approve`, and set `outside_workdir = \"deny\"` to refuse paths outside the working directory\n4. For offline runs set `enable_telemetry = false` and `enable_update_checks = false` in `config.toml`\n5. Pin a version and read the changelog before upgrading, since patch releases can carry marked breaking changes; serve token usage from third-party model servers (`stream_options.include_usage`)\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, Mistral Vibe CLI or OpenAI Agents API?\n\nOpenAI Agents API scores 73.3 (BB) on agent readiness against Mistral Vibe CLI's 58.4 (C), and leads in 4 of 7 scored categories.
