Use when a framed problem needs root-cause investigation rather than a symptom-level fix, applying Five Whys, Fishbone (Ishikawa), Current Reality Tree, and constraint identification. This should trigger when an issue's Root Cause Analysis point of view needs evaluation, or when a maintainer directly asks to find the root cause of a problem before proposing a fix. Part of Plinth Toolkit.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Root Cause Analysis Guide the identification of root causes, not symptoms, for a framed problem, using Five Whys, Fishbone (Ishikawa), Current Reality Tree, and constraint identification. **This is an interactive SKILL**. **What is covered in this Skill?** - Five Whys for a linear causal chain from a symptom to a root cause - Fishbone (Ishikawa) for categorized candidate causes across multiple dimensions - Current Reality Tree for interconnected causes and effects with a small number of core problems - Constraint identification for the limiting factor holding the current state in place - Choosing the technique(s) proportionate to the problem's complexity - Feeding root-cause findings into `023-assumption-analysis` and the remaining Functional Specification lenses ## Constraints Distinguish root causes from symptoms before recommending a fix. When this technique is orchestrated by another workflow, the orchestrator owns clarifying-question sequencing; when applied standalone, ask directly. - **MUST** read `references/022-root-cause-analysis.md` before applying Root Cause Analysis guidance …

How to install
mdr add jabrena/plinth/022-root-cause-analysis@sha256:f2a3374325638a3dThe line at the top of this page pins the label v0.19.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
