lenserfight: Skill for Claude Code

.agents/skills/supabase-rls-security-reviewer/SKILL.md

supabase-rls-security-reviewer is a skill for Claude Code, Codex from conectlens/lenserfight. It costs 55 tokens per session (233 once invoked), scanned A, original, MIT.

A security review guide for Supabase databases, including rules that control which users can read or change data. It also examines database permissions, exposed tables and views, and SQL functions.

In plain words
What is it for?
Reviewing access-control rules, authentication-sensitive database changes, exposed schemas, database views, SQL functions, and least-privilege migrations.
Why use it?
It helps catch policies or permissions that accidentally expose private data or allow more access than intended.

Skill for Claude CodeCodex

Written for Claude Code and Codex: disable-model-invocation in frontmatter, but also agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is conectlens/lenserfight's own configuration. It tells Claude Code and Codex how to work on lenserfight itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything lenserfight configures →

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

supabase-rls-security-reviewer 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 11d 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 it actually says

Supabase RLS Security Reviewer

Use when

  • any migration touches RLS, grants, policies, views, or SQL functions
  • public exposure, owner access, or admin access must be reviewed
  • least-privilege correctness is critical

Workflow

  1. Inspect exposure surface: schemas, tables, views, functions, and grants.
  2. Check RLS policy correctness by actor and operation.
  3. Return concrete risks, exploit paths, and hardened replacements.
  4. Run 'npx supabase migration up --local' to ensure the created migrations applied successfully.

Load only when needed

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
