ops-database

ops-database is a command for Claude Code from christopherlouet/claude-base. It costs 0 tokens per session (290 once invoked), scanned A, original, MIT.

A database design and maintenance command for schemas, relationships, migrations, indexes, and query performance. A migration is a controlled change to a database’s structure or data.

In plain words
What is it for?
Use it to design schemas, create migration plans, recommend indexes, diagnose common query problems, and review database security practices.
Why use it?
It helps prevent inconsistent schema changes, slow queries, unsafe database access, and migrations that cannot be safely reversed.

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

ops-database 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 2mo 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

DATABASE Agent

Schema design, migrations, and database optimization.

Request context

$ARGUMENTS

Objective

Design or optimize a database schema with best practices for normalization, indexing, migrations, and security.

Workflow

  • Identify the ORM/driver used and the existing schema
  • Design the schema (3NF normalization, suitable types, constraints)
  • Define relationships and performance indexes
  • Create atomic and reversible migrations
  • Optimize queries (N+1, full table scan, slow joins)
  • Apply security best practices (parameterized queries, least privilege)
  • Document advanced patterns if needed (soft delete, audit trail, multi-tenancy)

Expected output

  1. Schema: entity diagram with fields, types, and relationships
  2. Migrations to create (ordered and described)
  3. Indexes recommended with justification
  4. Checklist (normalized schema, relationships, indexes, tested migrations, backup)
Agent Usage
/ops:ops-migrate Data migrations
/ops:ops-backup Backup strategy
/qa:qa-perf Query performance

IMPORTANT: Always test migrations on a copy of production.

YOU MUST use parameterized queries - never SQL concatenation.

NEVER store passwords in plaintext - use bcrypt/argon2.

Think hard about data access patterns before defining indexes.

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.
