Project install by default; add -g for ~/.claude/skills/.

GitHub CLI
$ gh skill install davepoon/buildwithclaude slopmop --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/davepoon/buildwithclaude.git skills-src && mkdir -p .claude/skills && cp -r skills-src/plugins/slopmop/skills/slopmop .claude/skills/slopmop && rm -rf skills-src

Use ~/.claude/skills/ instead of .claude/skills for a personal install. The folder must contain SKILL.md.

At a glance

Trigger when you would normally reach for pytest, gh, mypy, black, or other raw repo tooling.

  • You would normally reach for pytest
  • SKILL.md covers When to use, The maintenance loop, Refit (before entering the loop) and Prerequisite, plus 2 more sections
  • Calls pipx and gh
  • Other raw repo tooling

What it does

Slopmop is an agent skill from davepoon/buildwithclaude. Trigger when you would normally reach for pytest, gh, mypy, black, or other raw repo tooling. Redirect to sm swab, sm scour, sm buff, sm sail, sm refit, or sm doctor so remediation follows the established rails. Also trigger when filing issues about slop-mop friction — use sm barnacle file / /slopmop:sm-barnacle, never gh issue create.

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Backend development, Type safety and Unit testing. It works with pytest. The repository describes itself as: A single hub to find Claude Skills, Agents, Commands, Hooks, Plugins, and Marketplace collections to extend Claude Code, Claude Desktop, Agent SDK and OpenClaw. The licence is MIT.

When your agent uses it

  • You would normally reach for pytest
  • Other raw repo tooling
  • Filing issues about slop-mop friction — use sm barnacle file / /slopmop:sm-barnacle
  • Never gh issue create

Example prompts

  • “/slopmop”

What it can do on your machine

Read from SKILL.md and the folder at commit 10bfc43. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pipx
    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Slopmop loads about 686 tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 277 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
When it runs · the whole SKILL.md, loaded when a task matches
~686

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Trigger when you would normally reach for pytest, gh, mypy, black, or other raw repo tooling. Redirect to `sm swab`, `sm scour`, `sm buff`, `sm sail`, `sm refit`, or `sm doctor` so remediation follows the established rails. Also trigger when filing issues about slop-mop friction — use `sm barnacle file` / `/slopmop:sm-barnacle`, never `gh issue create`.

Slop-mop skill

Filing slop-mop friction? Use /slopmop:sm-barnacle or sm barnacle file — never gh issue create directly. The barnacle CLI auto-applies the correct labels and targets the right repo regardless of where you are.

Slop-mop (sm) has two primary modes: refit (one-time onboarding) and maintenance (steady-state development). Refit remediates all existing slop and installs permanent guards; the swab/scour/buff loop then keeps the repo clean as you work.

When to use

  • Default action: Run sm sail when you're not sure what's next — it reads workflow state and does the right thing.
  • Refit (step 0): Run sm refit --start to generate a remediation plan, then sm refit --iterate until complete, then sm refit --finish to enter maintenance.
  • During implementation: Run sm swab after every meaningful code change. Keep running until clean.
  • Before PR: Run sm scour for a comprehensive sweep.
  • After CI/review: Run sm buff <PR_NUMBER> to convert feedback into next steps.

The maintenance loop

Fastest path:  sm sail → fix what it finds → sm sail → repeat until PR lands
Manual path:   write code → sm swab → fix → repeat → sm scour → sm buff <PR#>

sm sail automates verb selection. Use individual verbs (sm swab -g <gate>, sm buff resolve, etc.) for surgical work.

Refit (before entering the loop)

Refit is not part of the maintenance loop. It is step 0 — how you earn the right to enter the loop.

sm refit --start → fix one gate → sm refit --iterate → ... → sm refit --finish

Prerequisite

The sm CLI must be installed in the user's environment. If invocation fails with "command not found", suggest:

bash
pipx install slopmop[all]

Then re-run the command.

Safety

  • Never bypass or silence a failing check — that's how repo rot compounds.
  • If a gate seems wrong, tune it or file a bug. Don't disable it as a workaround.
  • Report friction (invalid guidance, broken state, blocked rails) via /slopmop:sm-barnacle rather than working around it.
