paperclip: Skill for Claude Code

Security Vulnerability Response Instructions

⚠️ CRITICAL: This is a security vulnerability. Everything about this process is confidential until the advisory is published. Do not mention the vulnerability details in any public commit message, PR title, branch name, or comment. Do not push anything to a public branch. Do not discuss specifics in any public channel. Assume anything on the public repo is visible to attackers who will exploit the window between disclosure and user upgrades.

Context

A security vulnerability has been reported via GitHub Security Advisory:

• Advisory: {{ghsaId}} (e.g. GHSA-x8hx-rhr2-9rf7)
• Reporter: {{reporterHandle}}
• Severity: {{severity}}
• Notes: {{notes}}

---

Step 0: Fetch the Advisory Details

Pull the full advisory so you understand the vulnerability before doing anything else:

gh api repos/paperclipai/paperclip/security-advisories/{{ghsaId}}

Read the description, severity, cvss, and vulnerabilities fields. Understand the attack vector before writing code.

Step 1: Acknowledge the Report

⚠️ This step requires a human. The advisory thread does not have a comment API. Ask the human operator to post a comment on the private advisory thread acknowledging the report. Provide them this template:

Thanks for the report, @{{reporterHandle}}. We've confirmed the issue and are working on a fix. We're targeting a patch release within {{timeframe}}. We'll keep you updated here.

Give your human this template, but still continue

Below we use gh tools - you do have access and credentials outside of your sandbox, so use them.

Step 2: Create the Temporary Private Fork

This is where all fix development happens. Never push to the public repo.

gh api --method POST \
  repos/paperclipai/paperclip/security-advisories/{{ghsaId}}/forks

This returns a repository object for the private fork. Save the full_name and clone_url.

Clone it and set up your workspace:

# Clone the private fork somewhere outside ~/paperclip
git clone <clone_url_from_response> ~/security-patch-{{ghsaId}}
cd ~/security-patch-{{ghsaId}}
git checkout -b security-fix
