yieldskill — Yield skill workflow SDK for Python

The Python implementation of the yield.v1 SDK execution contract (see ir/README.md). The import name is yieldskill because yield is a Python keyword.

Create a virtual environment before installation:

# macOS and Linux
python3 -m venv .venv
source .venv/bin/activate
python -m pip install yieldskill

# Windows PowerShell
py -m venv .venv
.\.venv\Scripts\Activate.ps1
python -m pip install yieldskill

Public PyPI releases use trusted publishing. Every wheel contains the matching Yield runtime for its platform.

The launcher preserves the selected Python environment for RunCommand, even when an adapter starts that interpreter without activating the environment.

from yieldskill import define_skill

def program(ctx):
    answer = ctx.ask_user("confirm-start", "Ready to start?")
    if answer != "yes":
        ctx.refused("user declined to start")
    tests = ctx.run_command("run-tests", "true", timeout_seconds=60)
    ctx.require(tests.exit_code == 0, "the test command passes", tests)
    return {"status": "ok"}

define_skill(program)

Declare the runner in the skill's skill.json:

{ "run": ["python3", "main.py"] }

Programs must be deterministic between yields — same journal, same operations, every execution. Clocks, RNGs, and filesystem reads are side effects: cross them through a yielded operation or leave them out.
