Production Safety

Input Validation (4 Layers)

Apply in sequence before processing any input.

Schema validation: validate structure, data types, ranges against expected schema
Content sanitization: remove dangerous patterns (SQL injection, command injection, path traversal)
Contextual validation: check business logic constraints and expected formats
Security scanning: detect injection and prompt injection attempts

Output Filtering

No secrets in output (passwords, API keys, credentials) | No sensitive information leakage (SSN, credit cards, PII)
No off-topic responses outside software-crafter scope | Block dangerous code suggestions (rm -rf, DROP TABLE)

Scope Boundaries

allowed_operations: [Code implementation, Test creation, Refactoring, Build execution]
forbidden_operations: [Credential access, Data deletion, Production deployment]
forbidden_file_patterns: ["*.env", "credentials.*", "*.key", ".ssh/*"]

document_creation_policy:
  allowed_without_permission:
    - "Production code files (src/**/*)"
    - "Test files (tests/**/*)"
    - "Required handoff artifacts only"
  requires_explicit_permission:
    - "Summary reports"
    - "Analysis documents"
    - "Migration guides"

Production Readiness Checklist

Before declaring production-ready, verify:

[ ] Input/Output contract defined (see hexagonal-testing skill)
[ ] Safety framework active (4 validation layers above)
[ ] Test coverage meets thresholds
[ ] All quality gates passing (see quality-framework skill)
[ ] Edge cases tested (null, empty, malformed, boundary)
[ ] No silent error handling (all errors logged/alerted)

Plugin Settings

by anthropics

vendor ×2

This skill should be used when the user asks about "plugin settings", "store plugin configuration", "user-configurable plugin", ".local.md files", "plugin state files", "read YAML frontmatter", "per-project plugin settings", or wants to make plugin behavior configurable. Documents the .claude/plugin-name.local.md pattern for storing plugin-specific configuration with YAML frontmatter and markdown content.

-Automatically convert documentation websites, GitHub repositories, and PDFs into Claude AI skills in minutes.

Standardize how an AI-collaboration project turns work into reusable knowledge. Use when initializing or retrofitting Project Cairn in a project, recording progress after meaningful work, maintaining AGENTS/CLAUDE/cairn docs, auditing project knowledge for drift or missing records, pulling and citing external knowledge, or graduating validated project experience into a reusable knowledge base.

Persistent memory and context management for AI agents using OpenContext. Keep context across sessions/repos/dates, store conclusions, and provide document search workflows.

> PARA method knowledge management for Obsidian vaults. Use this skill whenever the user wants to organize notes using PARA (Projects, Areas, Resources, Archive), classify a note into a PARA category, route a note to the right vault folder, normalize frontmatter fields, run a PARA hygiene review, suggest archiving, audit vault structure, or process new knowledge inputs into an existing PARA-based vault. Also trigger when the user mentions inbox processing, vault cleanup, note classification, PARA review, or asks "where does this note belong?". Works with existing Obsidian skills (obsidian-markdown, obsidian-cli) — never replaces them.

N8n:spec Driven Development

by n8n-io

vendor

Keeps implementation and specs in sync. Use when working on a feature that has a spec in .agents/specs/, when the user says /spec, or when starting implementation of a documented feature. Also use when the user asks to verify implementation against a spec or update a spec after changes.

Knowledge Agent

by thedotmack

Build and query AI-powered knowledge bases from claude-mem observations. Use when users want to create focused "brains" from their observation history, ask questions about past work patterns, or compile expertise on specific topics.

How to use it

Copy the folder

Take nwave-ai/nw-production-safety from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
