qa-resilience

qa-resilience is a skill for Codex from vasilyu1983/AI-Agents-public. It costs 37 tokens per session (2,156 once invoked), scanned A, original, MIT.

A guide for making distributed systems handle failures predictably, including slow, unavailable, or overloaded dependencies.

In plain words
What is it for?
Use it to design retries, deadlines, circuit breakers, overload limits, fallbacks, and controlled failure tests.
Why use it?
It helps prevent retries, timeouts, and outages from spreading through a system, while making recovery behavior testable.

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

qa-resilience 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.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/resilience_checker.py, scripts/test_resilience_checker.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

QA Resilience

Use this skill when reliability work is about failure behavior, overload protection, degraded mode, or resilience testing. The goal is not "add retries everywhere." The goal is predictable failure handling, clear ownership, and testable recovery behavior.

Quick Reference

Symptom Start With
slow or hanging dependency deadline and timeout budget
transient dependency failure bounded retry with jitter and retry budget
sustained dependency failure circuit breaker and fallback
rate-limited dependency honor Retry-After, expose degraded behavior, and test quota paths intentionally
one bad host in a healthy pool outlier detection or endpoint ejection
queue or pool saturation bulkheads, concurrency limits, load shedding
non-critical feature outage graceful degradation or feature flag fallback
resilience validation deterministic fault injection before chaos

When to Use This Skill

  • retries, deadlines, hedging, breakers, bulkheads, and overload protection
  • degraded-mode UX or API behavior
  • service-mesh or gateway resilience policy
  • chaos engineering, game days, DR drills, and fault injection
  • release gates based on failure behavior, not only happy-path load tests

Route Elsewhere


Workflow

  1. Identify the critical user journeys and the dependencies that can break them.
  2. Define the contract per dependency:
    • timeout or deadline budget
    • retry ownership
    • breaker or outlier policy
    • concurrency and queue limits
    • degraded behavior if the dependency is unavailable
  3. Decide where the policy lives:
    • app code
    • client library
    • mesh or gateway
  4. Test in stages:
    • deterministic fault injection
    • staged chaos in non-production
    • narrow prod canary or game day only with guardrails
  5. Define pass or fail signals:
    • burn rate
    • p95 or p99
    • fallback rate
    • breaker transitions
    • shed volume
    • recovery time

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.
