What it does
Memstack Security Rls Guardian is an agent skill from cwinvestments/memstack. Use this skill when creating or altering database tables in Supabase or PostgreSQL projects. Triggers include: CREATE TABLE, ALTER TABLE, migration files, 'RLS', 'row level security', 'new table', 'database schema'. Enforces Row Level Security policies on every table to prevent unauthorized data access. Do NOT use for general SQL queries or non-schema database tasks.
Its SKILL.md is about 3.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Databases, covering SQL and Database schema design. It works with SQL, Supabase and PostgreSQL. The repository describes itself as: Structured skill framework for Claude Code. 130 skills, persistent memory, TokenStack compression, localhost dashboard with 3-agent runner, real-time streaming, MCP tools.
When your agent uses it
- Altering database tables in Supabase
- PostgreSQL projects
- Include: CREATE TABLE
- Migration files
Example prompts
- “row level security”
- “new table”
- “database schema”
- “/memstack-security-rls-guardian”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Classify the Table
- Write the Migration
- Pre-Commit Checklist
- Audit Existing Tables
- Handle Special Cases
What it can do on your machine
Read from SKILL.md and the folder at commit 00370ce. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are sql and markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Memstack Security Rls Guardian loads about 3.4k tokens when it runs. Until then it costs about 100 tokens; SKILL.md has 541 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 541 words (~3,362 tokens).
“Enforces Row Level Security on every Supabase table creation, ensuring no table goes live without proper access policies. Provides 4 policy patterns, migration templates, pre-commit checks, and audit queries to find unprotected tables.”
