langchain-pop

Thin adapter and compatibility wrapper for persona-object-protocol.

Role

langchain-pop preserves a standalone packaging surface for LangChain users who want a minimal POP integration entrypoint. It exists to expose integration glue and migration continuity, not to redefine the Persona Object Protocol itself.

Canonical home

The canonical implementation now lives in persona-object-protocol, under its POP integration surface and examples:

• persona-object-protocol/integrations/langchain-pop
• persona-object-protocol/src/pop/integrations/langchain

Not this repo

• not the canonical persona protocol implementation
• not the architecture hub
• not the benchmark suite
• not the governance or audit layer

Minimal usage

pip install langchain-pop
python examples/langchain_middleware_demo.py --print-config

from langchain_openai import ChatOpenAI

from langchain_pop.agent import create_pop_agent

agent = create_pop_agent(
    pop_source="tests/fixtures/mentor.v1.json",
    model=ChatOpenAI(model="gpt-4o", temperature=0.0),
    tools=[],
)

For current protocol context, schema evolution, and integration guidance, start from persona-object-protocol and treat this repo as a compatibility wrapper.

Status

• deprecated standalone wrapper
• canonical home is persona-object-protocol
• kept for packaging continuity and thin integration examples

Notes

• The standalone package remains installable for now.
• Protocol semantics, schema, and canonical examples live in persona-object-protocol.
• Future consolidation may fold this wrapper completely into the parent repo.
