agentforge-reranker-cohere 0.4.0

Cohere managed-API reranker for AgentForge

agentforge-reranker-cohere

Cohere managed-API reranker for the AgentForge framework.

Implements the Reranker ABC from agentforge-core. Registers as agentforge.rerankers:cohere.

Installation

pip install agentforge-reranker-cohere[cohere]

Usage

from agentforge_reranker_cohere import CohereReranker

reranker = CohereReranker.from_config(
    api_key="...",
    model="rerank-english-v3.0",
)

Or via agentforge.yaml:

retrieval:
  reranker:
    name: cohere
    config:
      api_key: ${COHERE_API_KEY}
      model: rerank-english-v3.0

The reranker forwards (query, candidate_text) pairs to Cohere's Rerank API, normalises the returned scores to [0, 1] (Cohere already does this — the clamp is defensive), sorts descending, and truncates to top_k.
