agentic-os: Skill for Codex

.agents/skills/production-readiness/SKILL.md

production-readiness is a skill for Codex from KbWen/agentic-os. It costs 23 tokens per session (834 once invoked), scanned A, original, MIT.

A pre-release checklist for making sure application errors are visible in production monitoring, not only in developer consoles.

In plain words
What is it for?
Use it when reviewing error handling, crash reporting, or logging, and before shipping changes to check that errors include useful context and reach a production-visible log or monitoring system.
Why use it?
Tests can pass while real users experience failures that the team cannot see, especially when errors are sent only to debug-only logs.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is KbWen/agentic-os's own configuration. It tells Codex how to work on agentic-os itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agentic-os configures →

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

production-readiness 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 9d 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.

Production Readiness

Overview

Code that passes all tests but logs errors only via debug-only APIs (e.g., debugPrint, console.log in debug mode) is functionally silent in production. This skill enforces observability readiness before ship — ensuring the team is not blind during beta testing and production rollout.

When to Use

  • Auto-recommended for feature and architecture-change classifications.
  • Activate manually when working on error handling, crash reporting, or logging infrastructure.
  • Apply at /review (semantic error check) and /ship (readiness checklist).

Observability Checklist

1. Error Surface Audit (at /review)

For every catch / error-handling block in changed files:

Check Pass Fail
Logging call exists Logger.error(), log.error(), crashReporter.capture() Empty catch {}
Logger is production-observable Framework logger, crash reporter, structured stdout debugPrint(), print(), debug-only console.log
Error context is actionable Includes error type, operation, identifiers "error occurred", raw exception only

2. Log Sink Documentation (at /ship)

Document in Work Log where production errors go:

## Observability
- Error sink: [e.g., Sentry via Logger.error(), Crashlytics, stdout → CloudWatch]
- Health check: [e.g., /health endpoint, Firebase Vitals, uptime monitor]
- Rollback signal: [e.g., error rate > 2x baseline → revert]

If the project has no production logging infrastructure, document as Known Risk:

"No production error reporting configured. Errors in catch blocks will be logged to stdout only. Risk: silent failures in release builds if stdout is not monitored."

3. Rollback Telemetry (at /ship)

The rollback plan (per engineering_guardrails.md §12.5) must answer:

  • How will operators know the rollback is needed? (alert, dashboard, manual check)
  • How will operators know the rollback succeeded? (error rate drops, health check passes)

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.

production-readiness is a skill published in the GitHub repository KbWen/agentic-os (160 stars, last pushed yesterday), licensed MIT. It adds 23 tokens to every session and 834 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
