Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 31 stories with headroom

What would move OpenAI Agents SDK’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.

  1. Privacy posture — data-handling and privacy storiesPrevent my data from being used to train AI models

    nonemoves PA Scoreimpact 30

    The evidence pack covers SDK features (tools, handoffs, tracing, sessions, MCP, voice, sandboxing) but contains no mention of data-training opt-out, privacy controls, or API data usage policies relevant to model training.

  2. Agenticness — how well agents can access and operate the productSet up automations that run autonomously in the background

    nonemoves Built-in AIimpact 30

    Missing: scheduling/cron or event-trigger support, a deployment/hosting mechanism for unattended background execution, and any documentation of persistent autonomous operation outside a developer-invoked run.

  3. Agenticness — how well agents can access and operate the productUse an official CLI

    nonemoves agent-readyimpact 30

    The evidence pack is entirely about the Agents SDK library (Python/JS) — agent primitives, tools, tracing, sessions, MCP, streaming — with no mention of an official CLI tool for scaffolding, running, or managing agents; OpenAPI/CLI probes returned 404s.

  4. Agenticness — how well agents can access and operate the productIssue scoped/least-privilege API credentials for an agent

    nonemoves agent-readyimpact 30

    Missing: any mention of scoped/least-privilege credential issuance, API key scoping, or permission boundaries for agents.

  5. Agenticness — how well agents can access and operate the productSubscribe to events via webhooks

    nonemoves agent-readyimpact 30

    The evidence shows in-process streaming/tracing for observing agent run events, but nothing about registering webhook URLs or subscribing to events via HTTP callbacks.

  6. Agenticness — how well agents can access and operate the productExplore an interactive API reference with runnable examples

    nonemoves API qualityimpact 30

    The evidence pack shows only static documentation pages describing SDK concepts (agents, tools, handoffs, tracing) with no interactive API reference, no runnable code sandbox, and the OpenAPI/swagger probe explicitly returned 404 on all candidate paths, indicating no machine-readable interactive reference exists.

  7. Agenticness — how well agents can access and operate the productDownload a machine-readable API spec (OpenAPI or equivalent)

    nonemoves API qualityimpact 30

    The probe explicitly checked common OpenAPI spec locations and all returned 404, and no other evidence shows a machine-readable API spec being published for the Agents SDK.

  8. Agenticness — how well agents can access and operate the productRely on versioned APIs with a documented deprecation policy

    nonemoves API qualityimpact 30

    The evidence pack documents SDK features (agents, tools, tracing, handoffs) but contains no mention of API versioning scheme or a documented deprecation policy; the OpenAPI probe even returned 404s, and no versioning/deprecation docs are cited.
