agec 0.2.0

Pre-execution governance SDK for AI agents

AGEC

AGEC SDK is a pre-execution governance layer for AI agents.

It is not an agent framework. It validates Intent + Context + Execution Path immediately before an agent executes tools.

Installation

pip install agec

To verify the package exactly as a PyPI user would install it on Windows PowerShell:

python -m venv .venv
.\.venv\Scripts\python -m pip install agec
@'
from agec import AGEC, Context, ExecutionPath, Intent

decision = AGEC().validate(
    Intent(type="send_price_list", source="pypi_smoke_test", confidence=0.91),
    Context(
        facts={
            "price_list_status": "current",
            "campaign_status": "active",
            "customer_segment": "premium",
        }
    ),
    ExecutionPath(
        steps=[
            "crm.read_customers",
            "pricing.get_latest_list",
            "crm.filter_segment",
            "email.send_campaign",
        ],
        approved_path_id="price_campaign_v1",
    ),
)

print(decision.status)
'@ | .\.venv\Scripts\python -

Expected output:

proceed

You can also run the installed CLI demo:

agec-demo
agec-demo --audit-file agec-demo-audit.jsonl

The demo runs deterministic AGEC.validate(...) scenarios and prints proceed, review, suspend, halt, and reauthorize decisions.

Quick Start

from agec import AGEC, Intent, Context, ExecutionPath

agec = AGEC()

decision = agec.validate(
    intent=Intent(
        type="send_price_list",
        source="user_request",
        confidence=0.91,
    ),
    context=Context(
        facts={
            "price_list_status": "current",
            "campaign_status": "active",
            "customer_segment": "premium",
        }
    ),
    execution_path=ExecutionPath(
        steps=[
            "crm.read_customers",
            "pricing.get_latest_list",
            "crm.filter_segment",
            "email.send_campaign",
        ],
        approved_path_id="price_campaign_v1",
    ),
)

print(decision.status)
# proceed / review / suspend / halt / reauthorize

The decision is a structured object:

{
  "agec_id": "agec_123",
  "status": "proceed",
  "intent_score": 0.91,
  "context_score": 0.88,
  "path_score": 1.0,
  "reason": "Intent, context and execution path validated.",
  "audit_id": "audit_456"
}

Core API

agec.validate(intent, context, execution_path)

Models

Intent(type: str, source: str, confidence: float)
Context(facts: dict, context_hash: str | None = None)
ExecutionPath(steps: list[str], approved_path_id: str | None = None)
GovernanceDecision(status, reason, intent_score, context_score, path_score)

MVP Decision Logic

Condition	Decision
Intent invalid	halt
Intent ambiguous	review
Context missing	review
Context invalid	suspend
Path unknown	reauthorize
Path modified	halt
All valid	proceed

Audit Log

Every validation writes an in-memory audit event. You can persist it as JSONL:

from agec import AGEC, AuditLog

audit_log = AuditLog()
agec = AGEC(audit_log=audit_log)

# ... run validations ...

audit_log.save_json("audit.jsonl")

Simple Agent Wrapper

AGEC.wrap_callable(...) can guard a LangGraph node, an OpenAI Agents tool function, or any regular Python callable:

guarded_tool = agec.wrap_callable(
    tool_function,
    intent=intent,
    context=context,
    execution_path=execution_path,
)

result = guarded_tool()

The callable runs only when the decision status is proceed.

OpenAI and LangGraph Adapters

AGEC also ships named adapter helpers. They do not own API keys or create agent framework clients; they guard the callable you are about to execute.

from agec import wrap_openai_tool

guarded_send = wrap_openai_tool(
    send_email_campaign,
    intent=intent,
    context=context,
    execution_path=execution_path,
)

result = guarded_send()

For LangGraph-style nodes, static model objects or state-aware factories can be used:

from agec import Context, ExecutionPath, Intent, wrap_langgraph_node

guarded_node = wrap_langgraph_node(
    node,
    intent=lambda state: Intent(
        type=state["intent_type"],
        source="agent_plan",
        confidence=state["confidence"],
    ),
    context=lambda state: Context(facts=state["facts"]),
    execution_path=lambda state: ExecutionPath(
        steps=state["steps"],
        approved_path_id=state["approved_path_id"],
    ),
)

If AGEC returns anything other than proceed, the adapter raises AGECExecutionBlocked and the wrapped call is not executed.
