Amplifier Heuristic Scheduler Module

Simple heuristic-based scheduling for tool and agent selection in Amplifier.

Prerequisites

• Python 3.11+
• UV - Fast Python package manager

Installing UV

# macOS/Linux/WSL
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

Purpose

Provides basic scheduling strategies for event-driven orchestration:

• First-available selection
• Round-robin distribution
• Random selection with seed support

Contract

Module Type: Hook Mount Point: hooks registry Entry Point: amplifier_module_hooks_scheduler_heuristic:mount

Configuration

[[hooks]]
module = "hooks-scheduler-heuristic"
config = {
    strategy = "first"  # "first", "round-robin", or "random"
    seed = 42           # Optional: for reproducible random selection
}

Behavior

Registers handlers for decision events:

• decision:tool_resolution - Select tool from available options
• decision:agent_resolution - Select agent for task delegation
• decision:context_resolution - Decide context compaction strategy

Returns ToolResolutionResponse, AgentResolutionResponse, or ContextResolutionResponse with:

• Selected option
• Score (0.0-1.0)
• Rationale explaining selection
• Metadata for observability

Dependencies

• amplifier-core>=1.0.0
