open-agent-compiler 0.1.2

Python-first agent framework that compiles agent definitions into backend-specific configurations

OpenAgentCompiler

Python-first agent framework that compiles agent definitions into backend-specific configurations for OpenCode agents.

Installation

pip install open-agent-compiler

Or with uv:

uv add open-agent-compiler

For local/editable development:

uv add --editable ../OpenAgentCompiler

Quick start

from open_agent_compiler.builders import AgentBuilder, ConfigBuilder, ToolBuilder
from open_agent_compiler.compiler import compile_agent
from open_agent_compiler.writers import OpenCodeWriter
from open_agent_compiler._types import (
    ModelConfig, ModelOptions, ProviderConfig, ProviderOptions,
)

# Define a tool
search = (
    ToolBuilder()
    .name("file-search")
    .description("Search files by glob pattern")
    .from_script("scripts/file_search.py")
    .build()
)

# Configure the model
config = (
    ConfigBuilder()
    .provider(ProviderConfig(
        name="anthropic",
        options=ProviderOptions(api_key="env:ANTHROPIC_API_KEY"),
        models=(ModelConfig(
            name="sonnet",
            id="claude-sonnet-4-5-20250929",
            options=ModelOptions(temperature=0.0),
        ),),
    ))
    .default_model("anthropic/sonnet")
    .build()
)

# Build the agent
agent = (
    AgentBuilder()
    .name("my-agent")
    .description("My custom agent")
    .config(config)
    .tool(search)
    .system_prompt("You are a helpful assistant.")
    .build()
)

# Compile and write to disk
compiled = compile_agent(agent, target="opencode")
OpenCodeWriter(output_dir="build/").write(compiled)

Architecture

Builder -> AgentDefinition -> Compiler -> backend dict -> Writer -> disk -> Manager -> external process

• Builders -- Fluent API classes that produce immutable data types via .build()
• Compiler -- Transforms an AgentDefinition into a backend-specific dict
• Writers -- Persist compiled dicts to disk (project files, configs, scripts)
• Managers -- Async lifecycle managers that deploy/invoke/teardown agents

Development

uv sync --all-extras      # install with dev + bench deps
uv run pytest tests/ -v   # run all tests
uv run ruff check .       # lint
uv run mypy               # type check

Python version

Requires Python 3.12+.
