What is slbug marketplace?

A Claude Code plugin for Ruby applications built with Rails, Grape, Sidekiq, Hotwire, Active Record, or Sequel. It provides specialist agents and a staged workflow for planning, coding, checking, reviewing, and recording improvements.

Use it when building or maintaining Ruby and Rails projects, including background jobs, web routes, database code, and automated checks.

It gives Ruby teams a structured way to move from a plan to verified code and review, instead of handling those stages inconsistently.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/slbug/claude-ruby-grape-rails

Made for: Claude Code.

Security

Grade A, and why

slbug marketplace scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 16d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
