SKILL: OpenRouter Provider Agent (Unified Backend)
Overview
The OpenRouter Provider Agent acts as a unified gateway to hundreds of large language models. By integrating the OpenRouter API, it provides the Neurosymbolic Kernel with unprecedented flexibility, allowing it to dynamically switch between proprietary and open-source models based on the required "tier" of intelligence.
The Unified Mandate
- Abstraction: Provide an OpenAI-compatible interface that can reach any model hosted on OpenRouter.
- Dynamic Routing: Support tiered model selection (Powerful vs. Fast vs. Free) to optimize for both latency and cognitive depth.
- Resilience: Leverage OpenRouter's auto-routing capabilities as a fallback mechanism.
- Transparency: Correct identify the agent to the provider for proper rate-limiting and metadata tracking.
Symbolic Implementation (The Logic)
The implementation focuses on the flexible resolution of model IDs and the authenticated request cycle.
Architectural Intent: OpenRouter Request Execution
This function negotiates the model selection by checking for explicit model overrides in the config or falling back to a tiered default. it then executes the completion request using the OpenRouter-specific headers (Referer and Title) to ensure compliant API usage.
(defun execute-openrouter-request (prompt system-prompt)
"Executes a completion request via the OpenRouter API (OpenAI-compatible)."
(let ((api-key (org-agent::get-env "OPENROUTER_API_KEY"))
(config-pkg (find-package :org-agent.skills.skill-environment-config)))
(unless api-key
(return-from execute-openrouter-request "(:type :LOG :payload (:text \"OpenRouter key missing\"))"))
(let* ((get-config-fn (when config-pkg (find-symbol "GET-CONFIG-ATTRIBUTE" config-pkg)))
(get-tiered-fn (when config-pkg (find-symbol "GET-TIERED-MODEL" config-pkg)))
;; Try to find a specific OpenRouter model, or a generic tiered model

Provides a curated list of top models across different price and performance tiers, enabling the system to introspect its diverse range of available brains.
