postgres is a skill for Claude Code, Codex from Demerzels-lab/elsamultiskillagent. It costs 18 tokens per session (202 once invoked), scanned A, original, MIT.

A PostgreSQL database management connection for running SQL queries, changing database structures, improving indexes, handling backups, and monitoring performance. PostgreSQL is a database system used to store application data.

In plain words
What is it for?
Use it to list tables, query data, create indexes, manage schemas and extensions, back up or restore databases, and investigate slow queries.
Why use it?
It lets developers inspect and maintain a database from one workflow while requiring confirmation before destructive changes.

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

postgres scanned grade A with 1 finding 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 8d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What it actually says

PostgreSQL 🐘

PostgreSQL database management.

Setup

export DATABASE_URL="postgresql://user:pass@localhost:5432/dbname"

Features

  • SQL query execution
  • Schema management
  • Index optimization
  • Backup and restore
  • Performance monitoring
  • Extensions management

Usage Examples

"Show all tables"
"Run query: SELECT * FROM users"
"Create index on email column"
"Show slow queries"

Commands

psql "$DATABASE_URL" -c "SELECT * FROM users LIMIT 10"

Safety Rules

  1. ALWAYS confirm before destructive operations
  2. BACKUP before schema changes
Files

What ships with it

1 file 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.
