nosql

nosql is a skill for Claude Code, Codex from williamzujkowski/standards. It costs 17 tokens per session (441 once invoked), scanned A, a copy of gdpr, MIT.

A set of general practices for NoSQL databases, which store data without requiring a fixed relational table structure. It covers patterns, security, errors, testing, performance, and documentation.

In plain words
What is it for?
Use it when choosing NoSQL design patterns, validating inputs, handling failures, testing database code, and reviewing performance.
Why use it?
It gives a broad checklist for building and maintaining NoSQL-backed systems, though the input does not identify a specific database product.

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

nosql 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 3d 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

Nosql

Quick Navigation: Level 1: Quick Start (5 min) → Level 2: Implementation (30 min) → Level 3: Mastery (Extended)


Level 1: Quick Start

Core Principles

  1. Best Practices: Follow industry-standard patterns for database
  2. Security First: Implement secure defaults and validate all inputs
  3. Maintainability: Write clean, documented, testable code
  4. Performance: Optimize for common use cases

Essential Checklist

  • Follow established patterns for database
  • Implement proper error handling
  • Add comprehensive logging
  • Write unit and integration tests
  • Document public interfaces

Quick Links to Level 2


Level 2: Implementation

Core Concepts

This skill covers essential practices for database.

Key areas include:

  • Architecture patterns
  • Implementation best practices
  • Testing strategies
  • Performance optimization

Implementation Patterns

Apply these patterns when working with database:

  1. Pattern Selection: Choose appropriate patterns for your use case
  2. Error Handling: Implement comprehensive error recovery
  3. Monitoring: Add observability hooks for production

Common Pitfalls

Avoid these common mistakes:

  • Skipping validation of inputs
  • Ignoring edge cases
  • Missing test coverage
  • Poor documentation

Level 3: Mastery Resources

Reference Materials

Templates

See the templates/ directory for starter configurations.

External Resources

Consult official documentation and community best practices for database.

Files

What ships with it

3 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.
