ContextClip (Python)

Ported line-for-line from the TypeScript implementation. See the root README for the pitch, the prior-art table, and the scope decisions — this file only covers what's specific to running the Python code.

Install

pip install -e ".[dev]"

Quickstart

PYTHONPATH=src python3 examples/quickstart.py

from contextclip import ContextClipper

clipper = ContextClipper(budget_tokens=200, tail_messages=2)

status = clipper.check(messages)
if status.action == "over_hard_limit":
    result = await clipper.recover(messages)
    # result.action is "drained" or "summarized" — result.messages never
    # touches the last `tail_messages` of the original list.

Test

pytest

Status

Budget tracking, threshold checks, and staged drain-then-summarize recovery with tail preservation are real and tested. Not yet published to PyPI — contextclip is unclaimed there.
