v0.3.0

Highlights

Pi Coding Agent Support

agentabi now supports 5 coding agent CLIs. Pi is an open-source, extensible coding agent harness with clean JSONL streaming output.

session = Session(agent="pi")
result = await session.run(prompt="Fix the bug")

Capabilities: streaming, system prompts, session resume, tool filtering. Thinking events are skipped (no IR type yet).

Middleware Pipeline (from v0.2.2)

Pluggable middleware system for Session:

from agentabi.middleware import LoggingMiddleware, UsageMeterMiddleware, TimeoutMiddleware

session = Session(
    agent="claude_code",
    middleware=[TimeoutMiddleware(120), LoggingMiddleware(), UsageMeterMiddleware()],
)

Provider Reliability (from v0.2.2)

• stderr capture, exit code checking, and timeout enforcement across all native providers
• Capability declaration fixes (no more false supports_system_prompt: True)
• Codex/OpenCode result_text bug fix (#7)

Documentation

• examples/middleware.py demo script
• Updated providers and session API docs for Pi and middleware
