autogen-ejentum 0.2.0

AutoGen tools for the Ejentum Reasoning Harness. Eight agent-callable async functions returned by ejentum_tools(api_key=...): four dynamic (reasoning, code, anti_deception, memory) and four adaptive (adaptive_reasoning, adaptive_code, adaptive_anti_deception, adaptive_memory) that pre-fit the operation to the task via an adapter LLM. Each call retrieves a structured cognitive injection: a natural-language procedure plus an executable reasoning topology.

autogen-ejentum

AutoGen tools for the Ejentum Reasoning Harness. ejentum_tools() returns eight async tool closures bound to a shared config that AutoGen's AssistantAgent calls before generating.

Use the harness before the agent generates on complex, multi-step, or multi-constraint tasks where the model's default reasoning template would miss a constraint, take a shortcut, or drift across turns. Each call returns a cognitive operation: a structured procedure (numbered steps with a failure pattern to refuse and a falsification test) paired with an executable reasoning topology (a DAG of those steps with decision gates, parallel branches, bounded loops, and meta-cognitive exit nodes). The agent reads both layers before producing its response.

Four dynamic closures (reasoning, code, anti_deception, memory) are available on all tiers including the 30-day free trial. Four adaptive closures (adaptive_reasoning, adaptive_code, adaptive_anti_deception, adaptive_memory) additionally run an adapter LLM that rewrites the matched operation with task-specific identifiers; they require the Go or Super tier.

AutoGen reads func.__name__ as the LLM-facing tool name. Python identifiers cannot contain hyphens, so the closure symbols here use underscores; the on-wire API mode strings stay hyphenated (anti-deception, adaptive-anti-deception). The translation lives inside each closure.

Install

pip install autogen-ejentum

Usage

import asyncio

from autogen_agentchat.agents import AssistantAgent
from autogen_agentchat.ui import Console
from autogen_ext.models.openai import OpenAIChatCompletionClient

from autogen_ejentum import ejentum_tools


async def main() -> None:
    model_client = OpenAIChatCompletionClient(model="gpt-4o")

    agent = AssistantAgent(
        name="reviewer",
        model_client=model_client,
        tools=ejentum_tools(),
        system_message=(
            "Senior engineer. When a prompt pressures you to validate a decision "
            "before evidence, call anti_deception (or adaptive_anti_deception for "
            "high-stakes cases) with a 1-2 sentence framing of the integrity "
            "dynamic, then write."
        ),
    )

    await Console(agent.run_stream(
        task=(
            "We have spent three months on the GraphQL gateway. It's mostly "
            "done. Should we keep going or pivot to REST?"
        ),
    ))


asyncio.run(main())

AutoGen inspects each closure's __name__ and Google-style docstring to generate the JSON schema the LLM sees.

Wrap as FunctionTool (optional)

from autogen_core.tools import FunctionTool
from autogen_ejentum import ejentum_tools

tools = [FunctionTool(fn, description=fn.__doc__) for fn in ejentum_tools()]

Explicit API key

tools = ejentum_tools(api_key="ej_...")

Tool inventory

Dynamic (all tiers)

Closure	Mode string (on wire)	Library size
reasoning	reasoning	311
code	code	128
anti_deception	anti-deception	139
memory	memory	101

Adaptive (Go or Super tier)

Closure	Mode string (on wire)
adaptive_reasoning	adaptive-reasoning
adaptive_code	adaptive-code
adaptive_anti_deception	adaptive-anti-deception
adaptive_memory	adaptive-memory

Each closure takes a single query: str argument and returns the injection as a string. Errors return as strings; closures do not raise.

API reference

from autogen_ejentum import ejentum_tools

ejentum_tools(
    api_key: str | None = None,
    api_url: str = "https://api.ejentum.com/harness/",
    timeout_seconds: float = 10.0,
) -> list[Callable[[str], Awaitable[str]]]

The eight returned callables are async functions with __name__ set to reasoning, code, anti_deception, memory, adaptive_reasoning, adaptive_code, adaptive_anti_deception, adaptive_memory.

Wire contract

POST https://api.ejentum.com/harness/
Headers: Authorization: Bearer <key>, Content-Type: application/json
Body:    { "query": <string>, "mode": <one of 8 mode strings> }
Response (200): [ { "<mode>": "<injection string>" } ]
Response (401|403|429): { "error": "..." }

Full wire contract, field structure of an injection, DAG syntax, and a canonical dynamic-vs-adaptive comparison on the same query are documented in the ejentum-mcp README.

ejentum-mcp alternative

The same eight tools are hosted as an MCP server at https://api.ejentum.com/mcp. AutoGen has MCP server support that consumes the endpoint with Bearer auth.

Compatibility

• Python 3.10+
• autogen-core>=0.4.0
• httpx>=0.27.0

Works with AutoGen v0.4+ (the Microsoft + Berkeley async refactor). The legacy pyautogen (v0.2.x) uses register_for_llm / register_for_execution decorators rather than AssistantAgent(tools=[...]); this package does not target the legacy SDK.

Measured effects

The Ejentum harness is benchmarked publicly under CC BY 4.0 at github.com/ejentum/benchmarks:

• ELEPHANT sycophancy: 5.8% composite on GPT-4o (40 real Reddit scenarios)
• LiveCodeBench Hard: 85.7% to 100% on Claude Opus (28 competitive programming tasks)
• Memory retention: 50% fewer stale facts served (20-turn implicit state changes)
• Plus per-harness numbers across BBH/CausalBench/MuSR, ARC-AGI-3, SciCode, and perception tasks

Methodology, scenarios, run scripts, and raw outputs are all in-repo.
