bighub-openai 0.1.0b3

OpenAI adapter for decision learning for AI agent actions with BIGHUB.

bighub-openai

Better decisions for OpenAI tool calls.

Beta release: this is the first public Better Decision OpenAI adapter beta.

bighub-openai adds BIGHUB's Better Decision layer to OpenAI agents before they execute risky IT tool calls, turning proposed IT actions into better decisions before execution.

OpenAI Responses API  ->  bighub-openai          ->  BIGHUB
tool call             ->  proposed IT action     ->  Decision Packet + DecisionBrain
runtime               ->  decision signals       ->  execution mode or review
outcome later         ->  optional report        ->  future decisions improve

Use it when your OpenAI agent can take actions such as:

• granting Okta or IAM access
• triggering CI/CD deploys
• running Terraform, Kubernetes, or Argo CD actions
• rotating credentials
• posting incident updates
• continuing after Trivy, Syft, or SBOM security checks
• calling internal APIs that change production state

pip install --pre bighub-openai

For future stable releases, use:

pip install bighub-openai

Requires Python 3.9+.

Dependencies:

• bighub>=0.1.0b3,<0.2.0
• openai>=2.0.0,<3.0.0

Quickstart

import os
from bighub_openai import BighubOpenAI


agent = BighubOpenAI(
    openai_api_key=os.getenv("OPENAI_API_KEY"),
    bighub_api_key=os.getenv("BIGHUB_API_KEY"),
    actor="ops-agent",
    domain="it_actions",
)


@agent.action(system="okta", risk="high", environment="production")
def grant_access(user_id: str, group: str, duration: str) -> dict:
    return {"ok": True, "user_id": user_id, "group": group, "duration": duration}


response = agent.run(
    messages=[{"role": "user", "content": "Grant Alice temporary Okta admin access for 48h"}],
    model="gpt-5.5",
)

last = response["execution"]["last"]
print(last["status"])                   # executed, blocked, approval_required, tool_error
print(last["decision"].get("mode"))    # review, autonomous, constrained, blocked, needs_context
print(last["decision"].get("risk"))
print(last["decision"].get("reason"))

decision = last["decision"]
print(decision.get("salient_factors"))
print(decision.get("responsible_action_space"))

agent.action(...) auto-generates a strict JSON schema from the Python function signature and attaches system context. GuardedOpenAI remains available as a compatibility alias.

When to use bighub-openai

Use this adapter when your OpenAI-based agent makes tool calls that:

• change infrastructure or production state
• may require review depending on system, scope, environment, or timing
• benefit from decision-time and polled operational context
• should stop, pause for review, or ask for more context before risky execution

If your agent only reads data or produces text, you probably do not need this adapter.

---

How it works

For every tool call, the adapter follows the same loop:

1. The model proposes a tool call.
2. The adapter captures action, arguments, actor, domain, and system metadata.
3. BIGHUB evaluates the action and may return a Decision Packet, DecisionBrain signals, and execution guidance.
4. The adapter resolves the execution result: execute, block, or require approval.
5. If enabled, optional outcome reporting and memory ingestion happen after execution.

Recommended mental model:

OpenAI tool call -> proposed IT action -> Decision Packet -> DecisionBrain -> execution mode / review -> optional outcome reporting

---

Response Shape

Representative shape from run():

{
  "llm_response": {...},
  "execution": {
    "events": [...],
    "last": {
      "tool": "grant_access",
      "status": "approval_required",
      "decision": {
        "request_id": "req_abc123",
        "better_action": "Grant scoped Okta admin access for 2h instead of 48h",
        "mode": "review",
        "can_run": False,
        "needs_review": True,
        "needs_more_context": False,
        "should_not_run": False,
        "risk": 0.78,
        "reason": "Production admin access for 48h is broader than necessary.",
        "responsible_action_space": {
          "available": [],
          "constrained": [],
          "forbidden": [],
          "information_gathering": []
        },
        "salient_factors": [
          {
            "factor": "high_blast_radius",
            "severity": "warning",
            "reason": "Production admin access has broad impact."
          }
        ],
        "decision_packet": {...},
        "decision_brain": {...}
      },
      "recommendation": "review_recommended",
      "risk_score": 0.78,
      "enforcement_mode": "review"
    }
  }
}

The adapter returns the full raw BIGHUB decision under last["decision"]. When the backend returns the newer Better Decision fields, those remain the preferred application surface.

Primary decision signals

Field	Description
better_action	A real backend-produced alternative when available; otherwise None
mode	Execution mode such as autonomous, constrained, review, blocked, or needs_context
can_run	Whether the tool call can execute now
needs_review	Whether a human review should happen first
needs_more_context	Whether the agent should collect more information
should_not_run	Whether BIGHUB recommends not executing
risk	Top-level risk score when provided
reason	Human-readable reason when provided
responsible_action_space	Responsible action options grouped as available, constrained, forbidden, and information_gathering when returned by BIGHUB
salient_factors	Decision-time factors BIGHUB identified as important for this tool call, such as high blast radius, weak verifier coverage, unavailable rollback, active incident, or open obligations
decision_packet	Structured context used for the decision
decision_brain	DecisionBrain reasoning summary and related signals

responsible_action_space and salient_factors are explanatory decision signals. They do not override runtime gating. Execution is still controlled by mode, can_run, needs_review, should_not_run, recommendation, allowed, and requires_approval.

Execution statuses

Status	Description
executed	Tool ran successfully
blocked	Runtime prevented execution
approval_required	Waiting for human approval
tool_error	Tool raised an exception during execution

Compatibility signals

For backward compatibility, last may also expose convenience fields such as recommendation, risk_score, enforcement_mode, and legacy decision payload keys like allowed, result, or reason. Prefer the structured fields inside last["decision"] when they are present.

Configuration

agent = BighubOpenAI(
    bighub_api_key="bh_live_xxx",
    openai_api_key="sk-xxx",
    actor="ops-agent",
    domain="it_actions",
    decision_mode="submit",      # or "submit_payload"
    fail_mode="closed",          # fail safe on BIGHUB errors
    max_tool_rounds=8,
    model_selection="auto",
    provider_timeout_seconds=30.0,
    provider_max_retries=2,
    outcome_reporting=True,
    memory_enabled=True,
)

Key parameters:

• decision_mode: submit or submit_payload
• fail_mode: closed or open
• outcome_reporting: optional automatic reporting after execution
• memory_enabled: optional ingestion of tool-call decision events
• model_selection: routing hint forwarded to BIGHUB context

---

Registering tools

Basic registration:

agent.tool("deploy_service", deploy_service)

With metadata extracted from arguments:

agent.tool(
    "sync_argocd_app",
    sync_argocd_app,
    domain="it_actions",
    actor="ops-agent",
    action_name="argocd_sync",
    metadata_from_args=lambda a: {
        "system": "argocd",
        "environment": a.get("environment"),
        "app": a.get("app"),
    },
)

Other common patterns:

• value_from_args for cost-like signals
• target_from_args for resource targeting
• parameters_schema for custom JSON schema
• register_tool(...) for the full lower-level API

---

Streaming

for event in agent.run_stream(
    messages=[{"role": "user", "content": "Sync checkout-service in Argo CD production"}],
    model="gpt-5.5",
):
    if event["type"] == "execution_event":
        print(event["event"]["tool"], event["event"]["status"])

run_stream() emits incremental model output and execution events, then finishes with the same final response shape as run().

---

Async

from bighub_openai import AsyncBighubOpenAI


async with AsyncBighubOpenAI(
    openai_api_key=os.getenv("OPENAI_API_KEY"),
    bighub_api_key=os.getenv("BIGHUB_API_KEY"),
    actor="ops-agent",
    domain="it_actions",
) as agent:
    agent.tool("rotate_credentials", rotate_credentials)
    response = await agent.run(
        messages=[{"role": "user", "content": "Rotate production database credentials"}],
        model="gpt-5.5",
    )

---

Human-in-the-loop approvals

result = agent.run_with_approval(
    messages=[{"role": "user", "content": "Grant temporary Okta admin access for 48h"}],
    model="gpt-5.5",
    on_approval_required=lambda ctx: {
        "resolution": "approved",
        "comment": "approved by on-call",
    },
)

When BIGHUB returns an approval-required decision, the adapter pauses execution and calls on_approval_required with the decision context.

---

Optional outcome reporting

If outcome_reporting=True, the adapter can automatically report successful execution, blocked execution, and tool errors back to BIGHUB after the tool decision resolves.

This is optional. The primary wedge is still the Better Decision before execution.

---

Optional decision memory

If memory_enabled=True, the adapter ingests structured events about tool calls, decisions, and outcomes into BIGHUB memory for future retrieval and pattern detection.

---

Compatibility

The modern path is BighubOpenAI / AsyncBighubOpenAI.

Compatibility aliases remain available:

• GuardedOpenAI -> BighubOpenAI
• AsyncGuardedOpenAI -> AsyncBighubOpenAI
