SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Measures the variance in stochastic skill evaluations (skill-review) by running N parallel instances, aggregating results deterministically, and producing a clear verdict against a reference to decide if a perceived change is noise or meaningful.

Core Features & Use Cases

  • Parallel robust runs: launches N skill-review evaluations concurrently and collects raw scores.
  • Deterministic aggregation: delegates all stats to a dedicated aggregator to compute median, standard deviation, confidence-like interval, and verdict.
  • Baseline management: compares to archived baselines and emits a clear signal whether a change is BRUIT, REGRESSION, or AMELIORATION.
  • Use Case: when a skill's score oscillates across passes, enabling a validated baseline σ before declaring regression.

Quick Start

Invoke the robust evaluation on a target skill to quantify evaluator noise and determine if observed changes indicate a true regression.

Frequently Asked Questions about eval-robuste

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check if skill evaluation score changes are real or just stochastic noise?

To check if evaluation score changes are noise, run N parallel skill-review instances to quantify variance. This deterministic aggregation computes median and standard deviation, producing a clear verdict on whether a change is meaningful or just noise.

What is the best way to establish a baseline sigma for stochastic skill evaluations?

The best way to establish a baseline sigma for stochastic skill evaluations is by running multiple parallel passes. The process aggregates raw scores deterministically and outputs a baseline JSON file for reliable future regression comparisons.

How do I quantify variance when skill-review results fluctuate across multiple passes?

To quantify variance when skill-review results fluctuate across passes, launch N parallel evaluations concurrently. A dedicated aggregator script computes the standard deviation and confidence-like interval, determining if the score oscillation indicates true regression.

Are there limits on the number of parallel runs I can execute for skill evaluation?

Yes, parallel skill evaluation runs are enforced between N equals 2 and 10. You can execute larger runs by explicitly using the force flag, ensuring you acknowledge the increased computational overhead for extensive variance testing.

What outputs do I get from a robust skill evaluation to support regression decisions?

Robust skill evaluation outputs a Markdown report and a baseline JSON file. The Markdown report details the deterministic verdict of BRUIT, REGRESSION, or AMELIORATION, while the JSON provides the baseline sigma for future regression decisions.

How does deterministic aggregation handle evaluator noise in skill-review scores?

Deterministic aggregation handles evaluator noise by delegating raw scores from parallel skill-review runs to a dedicated script. It computes the median, standard deviation, and confidence-like interval to deliver a clear verdict against an archived reference.
