spa-ai 0.3.0

SPA AI — install Jidoka halts as PRs. A broken thread must stop the loom.

SPA AI

Sakichi Principle Actuator AI — a GitHub-native developer agent that installs Jidoka halts for failure classes developers currently absorb through vigilance.

"A broken thread must stop the loom." — Sakichi Vision 1

"The loom serves the weaver, not the reverse." — Sakichi Vision 22

When a failure happens, the question is never who missed it but which loom was absent (Vision 92).

Status: Phase 1 — MVP skeleton (CLI; one loom: pre-commit-formatter). Launch target: Phase 5 completion.

What SPA AI does

SPA AI scans a git repository, finds missing Jidoka halts — places where a defect is only caught downstream by a human — and installs them as pull requests. Pre-commit hooks that should exist. Silent-failure patterns that should raise. Type stubs that should be added. Flaky tests that should be quarantined. CI steps that fail-open when they should fail-closed. SPA AI sees where the weaver is standing last-line-of-defense and builds the loom that should have halted instead.

What SPA AI is not

Not an AI assistant. Not a nag bot. Not a karma-scoring surveillance tool. Not a "write code faster" pitch. Not a replacement for the developer.

The doctrinal source

All of SPA AI traces to Toyoda Sakichi (1867–1930), inventor of the Type G automatic loom — the first machine to stop itself when a thread broke. The principle: the operator must not be the last line of defense against defects. See docs/sakichi_100_visions.md for the full lineage.

Install (v0.1, dev)

git clone https://github.com/aki1770-del/spa-ai.git
cd spa-ai
pip install -e ".[dev]"

Requires Python 3.11+. v0.1 has zero runtime dependencies — the first two looms are deterministic detectors. The Anthropic SDK lands when the first LLM-driven loom does, per docs/principles.md Principle 1 (Sekishō-idai — accumulate one stone at a time).

Run

Scan a git repo for missing looms:

spa-ai scan /path/to/some/repo

Generate the patch for a specific loom (dry-run by default):

spa-ai propose /path/to/some/repo --loom pre-commit-formatter

Write the patch to disk (the weaver still owns the merge — SPA AI proposes; the human commits and opens the PR):

spa-ai propose /path/to/some/repo --loom pre-commit-formatter --apply

There is intentionally no spa-ai alert or spa-ai issue-open subcommand. Per docs/promises.md Promise 3, the loom is a pull request, not an alert; if we cannot offer a PR, we do not speak.
