beamcore/tools

Overview

beamcore/tools is a highly optimized, lightweight (0.3 billion parameters) function-calling model, fine-tuned from google/functiongemma-270m-it. Its primary purpose is to act as a pre-flight search and routing assistant for the Elixir-native Beamcore agent harness, designed for efficient on-device execution.

Key Capabilities

• Local Execution: Optimized for running locally to reduce latency and cost.
• Pre-flight Search Routing: Analyzes user requests to determine if codebase context is needed before engaging a larger reasoning model.
• Structured Tool Calls: Emits specific tool calls for workspace inspection, including:
  • glob: Finds files matching a pattern.
  • grep: Searches file contents by regex.
  • tree: Shows a compact directory tree.
  • read: Reads file contents with offset/limit.
• Token Minimization: By gathering necessary context locally, it drastically reduces token overhead and billing for subsequent calls to larger, more expensive frontier models.

Good For

• Agentic Software Engineering Workflows: Ideal for scenarios where large workspace structures and extensive tool schemas would otherwise lead to slow, expensive, and context-polluting interactions with large language models.
• Efficient Context Gathering: Automating the process of fetching relevant local files or code snippets based on user intent.
• Cost-Effective AI Agents: Reducing operational costs by minimizing the tokens sent to main reasoning models.
