experiment-at-home 0.7.1

The plumbing every local AI experiment rebuilds, built once.

The plumbing every local AI experiment rebuilds, built once. athome is one SDK, CLI, and skill set for the machinery every experiment repo grows anyway — content-keyed caching, sidecar workers, record/replay LLM caching, launchd scheduling, detached overnight runs, and resumable progress.

Get started

uv add experiment-at-home
uv run athome --help

Driving with an agent? Paste this:

Add experiment-at-home (uv add experiment-at-home) and wrap my most expensive
pipeline step in its @cached decorator, namespaced after this project.

Claude Code plugin (the athome skills)

/plugin marketplace add yasyf/experiment-at-home
/plugin install athome@experiment-at-home

Use cases

Stop re-paying for the same expensive artifact every rerun

A pipeline rerun that re-derives every intermediate burns minutes (or API dollars) to reproduce bytes you already had. Wrap the step; the cache is content-keyed under ~/.athome/cache, shared across every repo on the machine:

from athome import cached


@cached(ns="ingest", version=1)
async def parsed_pages(pdf_digest: str) -> list[str]:
    # the expensive part: OCR, chunking, whatever your pipeline re-derives
    ...

The second call with the same arguments returns from disk. Invalidation is one edit: bump version=2 and the old entries are never read again.

Send tonight's sweep off before you close the laptop

An overnight script tied to a terminal dies with the terminal, and nohup leaves you grepping for whether it finished. Detach it with a name:

uv run athome run --detach --name sweep -- uv run python sweep.py

The run gets its own log under ~/.athome/logs/runs/, and a completion sentinel records the exit code. In the morning, uv run athome run wait sweep returns instantly with that exit code — 0 or the failure you need to chase.

Move a corpus without wondering if it all arrived

rsync reports transfer success, not tree integrity — and macOS salts remote copies with ._* AppleDouble droppings. Mirror with verification:

uv run athome sync ~/corpora/traces backup-host:corpora/traces --move

Every file is sha256-verified against the source before --move deletes anything; a mismatch repairs and re-verifies, and an unverifiable tree blocks deletion outright.

More in the docs

• Record/replay LLM caching — replay yesterday's API responses in today's tests, byte-for-byte — llmcache
• Sidecar workers — call GIL-bound engines from free-threaded Python over a version-handshaked pipe — workers
• launchd agents — declarative Calendar/Interval/KeepAlive schedules, no plist authoring — launchd
• Resumable progress — JSONL work-sets where crashed units retry and finished ones skip — progress
• One config file — every knob in ~/.athome/config.toml, every module a pydantic-settings section — config

Read the docs for the full guide.

Status: alpha — the primitives above are shipped and tested (including on free-threaded Python 3.14); MLX serving recipes, OCR engines, batch LLM lanes, and the autoresearch harness land in 0.2–0.3.
