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)

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.
