chaos-resilience-scoring

chaos-resilience-scoring is a skill for Claude Code from dungnotnull/hybrid-harness-chaos-process-prm. It costs 89 tokens per session (3,203 once invoked), scanned A, original, MIT.

A framework for scoring how well software services withstand failures, based on chaos experiments, monitoring data, tests, and game-day results. It produces scores for individual services and the platform as a whole, with trends over time when previous scores exist.

In plain words
What is it for?
Use it to calculate service and platform resilience scores, compare services, monitor resilience maturity over time, and create reports or production-promotion gates.
Why use it?
It replaces informal confidence with repeatable measurements that can reveal weak services and track improvement. The scores can also support decisions about promoting changes to production.

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

chaos-resilience-scoring 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 12d 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.

Resilience Scoring (s24)

Purpose

Provide a quantitative, repeatable framework for measuring system resilience — transforming subjective "we think it's resilient" into objective scores that can be tracked over time, compared across services, and used as gates for production promotion.


Prerequisites

  • Security scan results from s11
  • Test results from s12 (E2E testing)
  • Chaos experiment results from s14-s19
  • [ | Observability data from s22
  • Policy governance from s24
  • Alert recommendations from s23

Input Contract

Input Source Required

Observability data (error rates, latency) s20 output Yes
Post-chaos test evidence s11 (rerun) Yes
Cost impact data s23 output No
Recommendations s21 output Yes
Previous resilience scores (trend) Previous s24 runs No

Output Contract

Service maturity matrix s25 (improvement roadmap) Table

Resilience Scoring Formula

Resilience Score = Σ(Component Scores × Weights) × Coverage Factor

Where:
  Component Scores (0-100 each):
    Availability Score    — How well did the service stay available?
    Performance Score    — How well did performance hold up?
    Recovery Score       — How fast did the service recover?
    Correctness Score    — Did the service behave correctly?
    Observability Score   — Could we see what was happening?

  Weights (sum to 1.0):
    Availability:    0.30
    Performance:     0.20
    Recovery:        0.20
    Correctness:     0.15
    Observability:   0.15

  Coverage Factor (0.0-1.0):
    = Experiments_Run / Experiments_Planned
    (penalizes services that skip experiments)

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.

chaos-resilience-scoring is a skill published in the GitHub repository dungnotnull/hybrid-harness-chaos-process-prm (19 stars, last pushed 3mo ago), licensed MIT. It adds 89 tokens to every session and 3,203 once invoked, about $0.0004 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.
