presonus-studiolive-mcp: Command for GitHub Copilot

.github/prompts/srg-model-fit.prompt.md

srg-model-fit is a command for GitHub Copilot from zarfld/presonus-studiolive-mcp. It costs 31 tokens per session (9,523 once invoked), scanned A, original, MIT.

A software reliability analysis guide for fitting Software Reliability Growth models to failure data. These models estimate how failure rates may change as defects are found and fixed.

In plain words
What is it for?
Use it to prepare a reliability growth report with model fitting, goodness-of-fit checks, predictions, and release recommendations.
Why use it?
It helps turn recorded test failures into model comparisons, reliability predictions, and evidence for release decisions.

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

srg-model-fit 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 3d 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.

## 1. Introduction

### 1.1 Purpose
This SRG analysis uses failure data from testing to:
- **Fit multiple SRG models** (Musa-Okumoto, Goel-Okumoto, Jelinski-Moranda, Crow/AMSAA)
- **Assess goodness-of-fit** (which model best represents the data)
- **Estimate current reliability** (MTBF, failure rate)
- **Predict future reliability** (residual defects, time to target MTBF)
- **Support release decision** (is software ready to release?)

### 1.2 SRG Concept (IEEE 1633 Clause 6.3)

**Software Reliability Growth (SRG)** is the phenomenon where:
- As defects are detected and fixed, reliability **increases** over time
- Failure rate **decreases** over time
- MTBF **increases** over time

**SRG Models** mathematically describe this growth process, enabling predictions.

srg-model-fit is a command published in the GitHub repository zarfld/presonus-studiolive-mcp (1 stars, last pushed today), licensed MIT. It adds 31 tokens to every session and 9,523 once invoked, about $0.0002 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 2026-09-08.
