## Which one, for what

### Auggie CLI (D)

Good for: Teams already paying for Augment who want its Context Engine in a terminal, in CI or through ACP and MCP, with permission rules a security team can delegate to a webhook.

Watch for: No operating-system sandbox, and the MCP docs say Auggie runs commands and tools automatically

### OpenAI Agents API (BB)

Good 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.

Ahead on:
- Reliability, 60 against 43
- Schema & documentation, 88 against 67
- Agent ergonomics, 80 against 65
- Security & auth, 87 against 47
- Payments & pricing, 30 against 20
- Maintenance & community, 87 against 38
- Transparency & trust, 85 against 59

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install

Watch for: Public beta since 10 September 2026 behind the agents=v1 beta header, with no GA date


## Why the edge

### Maintenance & community: OpenAI Agents API +49

- Auggie CLI (38): Graded on the stable line, as the brief asks. 0.36.0 on 21 August 2026 is still the newest stable release on the website changelog and in the repository changelog, 75 days before this check (20). In the 90 days from 6 August 2026 the stable line has two dated releases, 0.35.0 on 13 August and 0.36.0 on 21 August. The 1.2.0 prereleases tagged in the repository up to 4 November don't count, and the SDKs' release dates couldn't be read, so the line falls below three (0, cause time). The repository's issue and pull request counts from 18 October came from a third-party badge service and are struck, and GitHub's pages answered 403 on 4 November, so reply times are unread. A support portal, a subreddit and a dated website changelog. Earlier partial value kept and flagged (6). TypeScript SDK 0.2.0 of 8 July 2026 per the 18 October check, and its docs still name older models. The Python SDK's version couldn't be read (8). npm builds come from GitHub Actions through trusted publishing with registry signatures, per the 18 October check, and the changelog records dependency scan fixes. No public CI for the CLI (4). 20+0+6+8+4 = 38.
- 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.

### Security & auth: OpenAI Agents API +40

- Auggie CLI (47): Framework reading (telemetry defaults, approvals, guardrails, sandboxing), five lines as for the other harnesses. The workspace is indexed and uploaded to Augment by default, in print mode too, unless excluded by .gitignore or .augmentignore. A telemetry endpoint is listed with no description or opt-out found. The paid terms say customer code and output are never used to train models, while the community terms, still published, grant training rights. Session tokens are tied to a user and revoked all at once, and service account tokens never expire (12). Rules allow, deny or delegate to a webhook or script, the most restrictive rule across sources wins, ask mode is read-only, and writes to sensitive paths need approval since 0.34.0. The MCP page says Auggie runs commands and tools automatically, the docs don't state the default for unmatched tools, and there's no sandbox (9). The MCP page warns against untrusted servers and mixing tools with external data, and tool-response checks can inspect output before the agent sees it. No network control was found (6). Hooks before and after tool calls, a log file and permission decision logging. Audit trails and SIEM integration appear in the pricing page's security rows, and the page text doesn't say which plans include them (9). A disclosure address and GitHub private reporting in SECURITY.md, SOC 2 Type II and ISO/IEC 42001 named. No security.txt and no bug bounty found. On 4 November osv.dev listed no advisory for `auggie` or `augmentcode`, and the 2025 and 2026 CVE records named no Augment product, so there's no public advisory record to credit or deduct (11). 12+9+6+9+11 = 47.
- 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.

### Transparency & trust: OpenAI Agents API +26

- Auggie CLI (59): Proprietary. The licence is clear on subscription, redistribution and modification, but it says commercial use needs a separate agreement while plans are sold to businesses, and it names Augment Computing, Inc., which sold the CLI to Harness on 8 October. On 4 November the licence, terms and privacy policy still named Augment Computing, Inc., while the website footer read Harness, Inc. (12). The paid terms rule out training on customer code and treat it as confidential. The privacy policy (28 August 2025) gives no retention periods and lists no subprocessors, referring both to a request, and the docs say indexed code is stored by Augment without a retention period (12). The 1.x guide lists breaking changes and retired parts, and the terms promise no materially reduced functionality during an order, but no date for 1.x becoming the default and no notice period were found (8). A telemetry endpoint is disclosed on the network page, with no description of what's sent and no opt-out (3). 12+12+8+3 = 35.
- 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.

### Schema & documentation: OpenAI Agents API +21

- Auggie CLI (67): Framework reading. `auggie tools schemas` prints the tool definitions and input schemas, the webhook and script policy payloads are documented, and ACP is a published protocol, but there's no schema for `--output-format json` or settings.json (13). docs.augmentcode.com/llms.txt indexes every page with a Markdown twin (10). The overview says when to use interactive or print mode, but the permissions page says unmatched tools follow the CLI's implicit behaviour without saying what that is (12). Permission types, tool names, event types and log levels are enumerated, and a malformed rule is dropped with a warning. The 1.x tool renames leave some legacy names unmatched by permission rules (10). Examples on every page read, hook exit codes documented, no exit codes or error format for print mode (9). Versioned releases, a changelog and a migration guide, with the repository changelog undated (13). 13+10+12+10+9+13 = 67.
- 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.

### Reliability: OpenAI Agents API +17

- Auggie CLI (43): Local-package reading, as for the other closed-source harnesses. The official npm package with macOS, Linux and WSL stated, but the README asks for Node 22 or later while the docs and the package engines say Node 20, so 2 are held back (18). No public CI or test suite, since the source isn't published. The repository holds docs, examples and issues, not the CLI (0). Open crash or regression issues couldn't be counted. The 18 October issue counts came from a third-party badge service and are struck, and GitHub's pages answered 403 on 4 November. Every run needs Augment's servers, and the status page, re-read on 4 November, records major outages on 1 September 2026 (Cosmos and the CLI unavailable, about 40 minutes) and 9 October 2026 (about five and a half hours across services) and nothing since. The earlier partial value is kept and flagged (5). A changelog by version with fixes and improvements in sections, dated release notes on the website, and a 1.x guide with a breaking-changes section, though the repository changelog carries no dates (10). The guide, re-read on 4 November, still calls the `latest` 0.x channel the current stable line for production, while 1.x is in preview. Judgement call (10). 18+0+5+10+10 = 43.
- 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.

### Agent ergonomics: OpenAI Agents API +15

- Auggie CLI (65): Framework reading, adapted to a harness driven by a pipeline. `--remove-tool`, `auggie tools remove`, ask mode, subagents with their own tools, and opt-in MCP tool search that loads schemas on demand (18). `--max-turns`, `--quiet`, `--compact`, `--output-format json`, `--queue` and `--show-credits`. Budgets per user exist only on Enterprise (15). No documented exit codes or error format for print mode. Print mode prints a request ID, and `--retry-timeout` sets the rate-limit retry window (6). `--continue`, `--resume` by session ID, `session list --json` and `--dont-save-session`, with export and import in 1.x (15). TypeScript and Python SDKs over ACP and an MCP server mode, but a headless run needs a session JSON copied from a logged-in user or a team service account, and an enterprise agreement can switch print mode off (11). 18+15+6+15+11 = 65.
- 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.

## How the scores have moved

### Auggie CLI

- -1.7 on 4 November 2026: time
- +0.2 on 27 October 2026: checklist

### OpenAI Agents API

No score change since it was listed.

## Verdicts

**Auggie CLI.** Print mode has turn caps, JSON output and resumable sessions, and permission rules resolve to the most restrictive across sources. Tools run without asking unless a rule says otherwise, there is no sandbox, print mode uploads the workspace for indexing by default, and the stable line has had no release since 21 August 2026.

**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.

## Before you call either

### Auggie CLI

1. Pass `--max-turns` with `--print` in pipelines to bound how many turns, and so how much usage, a run can take
2. Commit deny rules to .augment/settings.json before an unattended run. Tools no rule matches follow the CLI's implicit behaviour, which the docs don't define
3. Add secrets and data directories to .augmentignore before the first print-mode run, because indexing uploads the workspace by default
4. Use a service account token in CI on team and Enterprise plans. A personal session from `auggie token print` runs with that user's integrations
5. Pin the version in CI. `latest` is 0.x, while `preview` and `daemon` carry 1.x prereleases whose permission rules ignore some legacy tool names

### OpenAI Agents API

1. 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
2. Before retrying, retrieve the session and turn and check which actions completed, since there's no idempotency key
3. Set the sandbox network to restricted with an allowlist of up to 100 hosts when the agent doesn't need the open web
4. Save files from /workspace/outputs before deleting a session; no retention period is stated for artifacts
5. Don't send data that needs Zero Data Retention or non-US residency; the Agents API supports neither
