github-design

github-design is a skill for Claude Code from parisgroup-ai/imersao-ia-setup. It costs 76 tokens per session (3,236 once invoked), scanned A, original, MIT.

A set of conventions for organizing GitHub repositories and their automation. GitHub is a service for hosting code; this covers its workflows, issue and pull-request templates, ownership rules, labels, branch protection, and project boards.

In plain words
What is it for?
Use it to set up a repository, create GitHub Actions workflows, design issue or pull-request templates, organize labels and milestones, configure branch protection, or set up GitHub Projects.
Why use it?
It helps keep repository settings and collaboration files consistent as a project grows. Clear ownership, review rules, and automation reduce confusion around changes and releases.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

github-design 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 9d 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.

GitHub Actions Best Practices

Reusable Workflows

    inputs:
      node-version:
        description: 'Node.js version'
