SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Deep bug analysis to break the fix-forget-repeat cycle by guiding teams through a structured root-cause and prevention workflow and capturing knowledge into specs.

Core Features & Use Cases

  • Root-cause categorization across missing specs, cross-layer contracts, change propagation failures, test gaps, and implicit assumptions.
  • Failure analysis and prevention planning: identify why fixes failed and what preventive measures would avert recurrence.
  • Knowledge capture and spec updates: generate actionable specs, checklists, and templates to codify lessons learned.
  • Use Case: after shipping a bug fix, run this skill to produce a spec update and a post-mortem-style report for the team.

Quick Start

Create a post-fix analysis using the five-dimension framework and commit updates to the project's specs.

Frequently Asked Questions about trellis-break-loop

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

FAQPage Schema
How do I write a postmortem after fixing a bug to prevent recurrence?▼

A postmortem analyzes a recently fixed bug to identify root causes and prevention strategies. It categorizes failure modes across missing specs and test gaps, then captures knowledge into actionable spec updates to break the fix-forget-repeat cycle.

What is the best way to capture bug root-cause analysis into project specs?▼

Capturing root-cause analysis into specs involves running a structured post-fix workflow that identifies failure modes and generates actionable checklists and templates. This codifies lessons learned directly into project specifications for future prevention.

How do I categorize root causes when analyzing a software bug fix?▼

Categorize root causes across five dimensions: missing specs, cross-layer contracts, change propagation failures, test gaps, and implicit assumptions. This structured categorization reveals specific failure scenarios and guides targeted prevention mechanisms.

Can I generate spec updates automatically from a bug postmortem?▼

Yes, a bug postmortem can generate spec updates automatically by analyzing the fixed bug and outputting a structured, actionable report. This report contains prevention strategies and templates ready for direct integration into your project specifications.

Why do we keep fixing the same software bugs repeatedly?▼

Repeated bugs stem from a fix-forget-repeat cycle lacking deep root-cause analysis. Breaking this loop requires identifying implicit assumptions and test gaps, then codifying prevention strategies into project specs to ensure lessons are retained.

What should be included in a bug prevention checklist for software engineering?▼

A bug prevention checklist should include root-cause categories, identified failure scenarios, and targeted prevention mechanisms. It outputs a structured postmortem report with actionable spec updates and templates to avert future recurrence.
