sage-sanctum-sdk 0.2.7

SDK for building agents that run within Sage Sanctum infrastructure

Sage Sanctum Agent SDK

SDK for building agents that run within the Sage Sanctum secure multi-agent execution platform.

Features

• SPIFFE Authentication - Automatic JWT SVID management for agent identity
• Transaction Tokens (TraT) - IETF-standard authorization for scoped transactions
• LLM Gateway Integration - Route LLM calls through authenticated, policy-enforced gateways
• Multi-Provider Support - OpenAI, Anthropic, and Google via unified interface
• SARIF Output - Standard static analysis output format for GitHub Code Scanning
• Testing Utilities - Mock gateway, LLM, and TraT clients for unit testing

Quick Start

from sage_sanctum import AgentContext, AgentRunner, SageSanctumAgent, AgentResult
from sage_sanctum.io.inputs import AgentInput, RepositoryInput
from sage_sanctum.io.outputs import SarifOutput, Finding, Location
from sage_sanctum.llm.model_category import ModelCategory


class MySecurityAgent(SageSanctumAgent):
    @property
    def name(self) -> str:
        return "my-security-agent"

    @property
    def version(self) -> str:
        return "0.1.0"

    async def run(self, agent_input: AgentInput) -> AgentResult:
        # Get an LLM client for analysis
        llm = self.context.create_llm_client(ModelCategory.ANALYSIS)

        # Your agent logic here...
        response = llm.invoke([...])

        return AgentResult(
            output=SarifOutput(
                tool_name=self.name,
                tool_version=self.version,
                findings=[...],
            ),
            exit_code=0,
        )


# Entry point
if __name__ == "__main__":
    import sys
    sys.exit(AgentRunner(MySecurityAgent).run())

Installation

pip install sage-sanctum-sdk

Architecture

Agents run in isolated containers with no direct network access. All external communication (LLM calls, MCP tools, packages) flows through authenticated gateways:

Agent Pod (seccomp: no AF_INET)
  └── Agent SDK
       ├── SPIFFE JWT (identity)
       ├── Transaction Token (authorization)
       └── Gateway Client (Unix socket)
            └── LLM Gateway → OpenAI / Anthropic / Google
