vibe-production-mindset

vibe-production-mindset is a skill for Claude Code from ash1794/vibe-engineering. It costs 37 tokens per session (717 once invoked), scanned A, original, MIT.

A production-readiness checklist for code that may serve many users. It checks logging, tracing, metrics, alerts, error handling, validation, and fallback behavior.

In plain words
What is it for?
Use it while building APIs, data-processing code, or user-facing features, and before calling production work finished.
Why use it?
It helps catch failures that may only appear after deployment, such as network errors, missing files, or invalid input.

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

vibe-production-mindset 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 5d 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.

vibe-production-mindset

The gap between "works on my machine" and "works in production" is where incidents live.

When to Use This Skill

  • Starting any implementation that will run in production
  • When implementing API endpoints, data processing, or user-facing features
  • Before declaring a feature "done"
  • When the user cares about production quality

When NOT to Use This Skill

  • Prototypes or spikes explicitly marked as throwaway
  • Internal scripts that run once
  • Test code (different quality criteria)
  • When the user says "just get it working"

The Checklist

Imagine this code serves 1 million users. Check:

1. Observability

  • Structured logging at key decision points (not just errors)
  • Tracing/correlation ID propagated through the request
  • Metrics for key operations (latency, success/failure counts)
  • Alerts defined for anomalies

2. Error Handling at System Boundaries

  • External API calls have timeouts
  • External API calls have retries with backoff
  • File I/O handles "file not found" and "permission denied"
  • Network errors are handled (connection refused, timeout, DNS failure)
  • Database errors are handled (connection lost, constraint violation)

3. Input Validation

  • All external input validated before processing
  • Size limits on string/array inputs
  • SQL injection prevention (parameterized queries)
  • XSS prevention (output encoding)
  • Authentication checked before authorization

4. Graceful Degradation

  • Circuit breakers for external dependencies
  • Fallback behavior when dependencies are unavailable
  • Graceful shutdown (drain connections, finish in-flight)
  • Health check endpoint

5. Resource Management

  • Connections closed/returned to pool
  • Goroutines/threads have lifecycle management
  • Memory bounded (no unbounded growth)
  • File handles closed

Steps

  1. Read the implementation
  2. Run through the checklist — not every item applies to every feature
  3. Flag gaps — only for items that DO apply
  4. Recommend fixes — specific, not generic

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.
