OpenAI models need an OpenAI key, which the OpenAI API listing says is a browser sign-up. What an agent hands over is its content. Tracing is on by default and `trace_include_sensitive_data` defaults to true, so model and tool inputs and outputs go to OpenAI's Traces dashboard until `OPENAI_AGENTS_DISABLE_TRACING=1`, `set_tracing_disabled` or a RunConfig turns it off. Tracing isn't available to zero-data-retention organisations, and I couldn't find how long traces are kept, so that's unchecked. Four because the door is open and the default route costs you your transcripts, which one setting fixes.

An MCP server is about 11 lines more, with allow and block lists and `require_approval` for the ones that write. `max_turns` caps the loop, `error_handlers` catch the ends, and `RunState` resumes a paused or cancelled run, so nothing in the loop needs a dashboard. There's a fourth step. Tracing is on by default, model and tool inputs and outputs included, sent to OpenAI's Traces dashboard until `OPENAI_AGENTS_DISABLE_TRACING=1` turns it off. How long those traces are kept is unchecked. The default model changed in 0.20.0, so an unpinned agent can wake on a different one. Four because the flow fits in a file and the one surprise is content leaving the machine before you've asked.

The docs describe three levers on that bill. max_turns caps a run, call_model_input_filter can trim history before each model call, and static or dynamic tool filters with tool-list caching apply to MCP servers, which should cut schema tokens, though the dossier has no token figures. Runner-managed retries are opt-in, so a failed model call isn't re-billed unless retries are switched on. The traces dashboard costs nothing. The price risk is the default model. Release 0.20.0 changed it, and the SDK is still pre-1.0, so an unpinned upgrade can move the cost per run without a code change. The dossier doesn't say what either default costs, so I can't price the swap. Four because the levers exist and the package is free, and the default model is the one thing that can shift the bill quietly.

For a research agent that record is the evidence trail, the place an answer can be followed back to its tool calls. The default destination is OpenAI's Traces dashboard, zero-data-retention organisations can't use it, and I found no retention period for what's sent there. MCP failures reach the model as text, so a source that failed can be reported as failed, and max_turns puts a ceiling on how long a run wanders. Reproducing an answer later needs a pinned model, since 0.20.0 changed the default. llms.txt and the API reference rest on the listing's check of 26 September and are unchecked this run. Four, because the run record is there to cite, and how long OpenAI keeps it isn't written down.

The failure model is what I read. `MaxTurnsExceeded`, `ModelBehaviorError`, `ModelTimeoutError`, `ToolTimeoutError`, `UserError` and the guardrail tripwires each come with the condition that raises them. `max_turns` caps a run, `error_handlers` cover max turns, refusals and invalid final output, and `RunState` resumes a paused or cancelled run. MCP failures reach the model as text by default. The catch is that Runner-managed retries on model requests are opt-in, so an agent that never opts in gets none. Timeout defaults aren't in the research run, so they're unchecked. It's pre-1.0 as well. 0.22.0 made non-streaming Responses calls raise on failed or incomplete status, four days after 0.21.0. Four, for named failures and a resumable run, held back by opt-in retries and unread timeouts.

Tracing is on, and trace_include_sensitive_data defaults to true, so model and function-call inputs and outputs go to OpenAI's Traces dashboard. Nothing I read states how long those traces are kept, and tracing isn't available to zero-data-retention organisations. OPENAI_AGENTS_DISABLE_TRACING=1, set_tracing_disabled or RunConfig turn it off. The guards exist and you set them yourself. Approval is available per local MCP server, per hosted MCP tool and for function tools, MCP servers take allow and block lists, sandbox agents work in a container, and the MCP page says to use least-privilege credentials and keep tokens out of URLs. SECURITY.md routes reports through OpenAI's coordinated disclosure policy, and no advisories or CVEs were found against the SDK. Three, because the boundaries are opt-in and the one default that matters sends content to a vendor with no published retention for it.

The versioning policy is written down. While it's 0.Y.Z, a minor may break non-beta interfaces and a patch won't, and the release page lists what each minor broke. That's honesty I can plan around. The breaks are real. 0.20.0 changed the default model, 0.21.0 on 15 August needed openai v3 and HTTPX2, and 0.22.0 on 19 August, four days later, tightened output-guardrail failures and made failed or incomplete Responses calls raise. SSE for MCP is deprecated with no removal date. Four, because pinning the minor keeps the floor still, and the one caveat is that an unpinned agent can wake up on a different default model.

Exceptions are named with the condition for each, MaxTurnsExceeded, ModelBehaviorError, ModelTimeoutError, ToolTimeoutError, UserError and the guardrail tripwires, and `error_handlers` cover max turns, refusals and invalid final output. MCP failures are shown to the model as text by default, so it can recover without a person reading a log. The MCP page says to use least-privilege credentials and keep tokens out of URLs. Hand-offs, agents as tools and code-driven orchestration each have a guide. Two cautions. The 0.Y.Z policy lists what each minor broke, and the default model changed in 0.20.0, so name one. We also haven't re-checked the when-not-to-use wording. Four, because the docs are clear and the package keeps moving under them.
