From the source SKILL.md

Row-Level Security lets a table's owner attach POLICY rules that filter which rows a user can SELECT/UPDATE/DELETE. The rules are applied at rewrite time (before the planner runs), so RLS-filtered rows never even reach the executor. But that only works if the planner can't accidentally leak filtered-out row content by pushing untrusted qualifications below the RLS filter — hence the security-barrier infrastructure and the leakproof function attribute.

What this skill does

Row Level Security is a community-contributed Claude Code skill in the security-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/row-level-security/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Row Level Security Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 153,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Frequently asked questions

How do I install the Row Level Security Claude Code skill?
Install via the ClaudSkills desktop app (one click) or copy SKILL.md from the source repository to ~/.claude/skills/row-level-security/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Row Level Security skill?
Use Row Level Security when your Claude Code task falls under the Security category — specifically in the security misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Row Level Security" or describe the task and let Claude pick). Browse related skills at /category/security/.
What is a Claude Code skill and how does the Row Level Security skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Row Level Security is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
