slopstopper-cli

The SlopStopper quality suite, packaged as a Python CLI on PyPI.

Status: Beta. Every check in the public catalogue runs through this package. The CI workflows under .github/workflows/ss-*.yml install the pinned slopstopper-cli via jdx/mise-action and call slopstopper run <category>:<check> — same code path you use locally.

Install

Quick standalone try (unpinned):

pipx install slopstopper-cli
slopstopper --version
slopstopper checks list
slopstopper doctor

Published to PyPI on every release tag. pipx upgrade slopstopper-cli pulls the latest. Each release is also attached to the latest GitHub Release with a Sigstore build-provenance attestation — verify with gh attestation verify <wheel> --owner hungovercoders.

Pinned suite (a repo you'll keep — local and CI run the same version):

curl -fsSL https://raw.githubusercontent.com/hungovercoders/slopstopper/main/install.sh | bash

Requires mise. install.sh pins slopstopper-cli + task in mise.toml (the single source of truth both local runs and CI read) and seeds the ss-*.yml workflows. Move the pin with install.sh --upgrade-cli / --cli-version.

Development (editable, from a clone of this repo):

pip install -e ./cli
slopstopper run hygiene:docs-size

CLI surface

slopstopper run <category>:<check>             # run a check, write reports under .ss/reports/
slopstopper emit <c>:<n> --target {pr-comment,issue}
slopstopper discover <check> --event <e>       # resolve pages.<check> from sitemap / changed / list
slopstopper config get <key> [<default>]       # read .slopstopper.yml
slopstopper templates {list, path <n>, eject <n>}   # inspect / customise bundled templates
slopstopper serve                              # bundled static server (auto-detects worker/headers.json)
slopstopper checks list [--category <c>] [--json]
slopstopper doctor                             # verify external tools are installed
slopstopper --quiet …                          # suppress decorative output (CI logs)

slopstopper with no args prints a banner of the commands above plus a quick-start block.

Run the tests

# From the repo root:
task -t cli/Taskfile.yml test

# Or from cli/:
task test

# Filter to a single test:
task -t cli/Taskfile.yml test -- -k docs_size

The same task test target is what CI runs (see .github/workflows/ci-cli.yml), so local and CI invocations stay in sync. The Taskfile creates and reuses a project-local venv at cli/.venv/ (gitignored) so it doesn't conflict with system Python under PEP 668.

This workflow is slopstopper-internal — it is not part of the distributed ss-*-check.yml suite and is never seeded into adopter repos.

Layout

• slopstopper/cli.py — argparse dispatcher + bare-invocation banner
• slopstopper/output.py — shared formatters (running / success / warn / error / footer / --quiet)
• slopstopper/config.py — .slopstopper.yml reader (stdlib-only YAML subset)
• slopstopper/templates.py — bundled-template resolver + templates {list, path, eject} API
• slopstopper/emit.py — gh CLI wrapper for PR comment + main-branch issue emission
• slopstopper/discovery.py — pages-to-audit resolver for reliability checks
• slopstopper/checks/ — one module per check; registry in __init__.py
• slopstopper/data/ — bundled Playwright specs, lighthouserc dev/prod, server.js

Adding a check

1. Add slopstopper/checks/<name>.py exposing run(args) -> int. Start the module docstring with a one-line summary (slopstopper checks list reads it).
2. Register it in slopstopper/checks/__init__.py's REGISTRY dict.
3. Write the report to .ss/reports/<category>/<name>-report.md in the CWD.
4. Use from slopstopper import output for any user-facing print calls so --quiet and the consistent visual language come for free.
5. If the check should be postable to a PR or issue, declare a META dict in the module — emit.py reads it.

Skills for agents

The trio under .claude/skills/slopstopper-{install,update,triage}/SKILL.md is the long-form playbook for Claude Code agents working with this CLI. Update them when you add or rename a check, env var, or task ss:* target.
