agentabi 0.2.1

Unified async Python API for driving coding agent CLIs — Claude Code, Codex, Gemini CLI, and more

agentabi

Unified interface layer for agentic coding CLIs.

One interface. Any coding agent.

What is agentabi?

agentabi provides a stable, unified interface (an "ABI") for interacting with different agentic coding CLIs. Write your integration once, swap agents with a config change.

Supported Agents

Agent	Provider	Status
Claude Code	Anthropic	Implemented
Codex	OpenAI	Implemented
Gemini CLI	Google	Implemented
OpenCode	Open Source	Implemented

Installation

pip install agentabi

With optional SDK integrations:

pip install agentabi[claude]   # Claude Code SDK support
pip install agentabi[codex]    # Codex SDK support
pip install agentabi[gemini]   # Gemini CLI SDK support
pip install agentabi[all]      # All optional SDKs

Note: Each agent's CLI must be installed separately (e.g., claude, codex, gemini, opencode).

Quick Start

Run a task

import asyncio
from agentabi import Session

async def main():
    session = Session(agent="claude_code")
    result = await session.run(prompt="Fix the bug in auth.py")
    print(result["status"])       # "success"
    print(result["result_text"])  # agent's response

asyncio.run(main())

Stream events

async for event in session.stream(prompt="Explain this code"):
    if event["type"] == "message_delta":
        print(event["text"], end="")

Sync convenience

from agentabi import run_sync

result = run_sync(prompt="List Python files", agent="codex")

Discover available agents

from agentabi import detect_agents, get_agent_capabilities

agents = detect_agents()          # ["claude_code", "codex", ...]
caps = get_agent_capabilities("claude_code")
print(caps["supports_streaming"]) # True

Use Cases

• Fleet Management — Unified entry point for managing multiple coding agents
• Agent-to-Agent Calls — Translation layer for inter-agent invocation
• Benchmarking — Run the same task across agents, compare results
• Fallback & Routing — Automatic failover and cost-aware routing
• Middleware Pipeline — Inject logging, metering, security scanning, audit trails
• CI/CD Integration — Vendor-agnostic agent integration for pipelines

Ecosystem

agentabi is part of a layered stack:

agentabi  →  Agent CLI unified interface  →  like an OS ABI
llmir     →  LLM API format conversion    →  like a compiler IR

• llmir — LLM Intermediate Representation for converting between LLM provider API formats (OpenAI, Anthropic, Google)
