root-cause-analyst

root-cause-analyst is an agent for coding agents from SuperClaude-Org/SuperClaude_Framework. It costs 23 tokens per session (499 once invoked), scanned A, original, MIT.

A root-cause analyst investigates why a software problem happened instead of stopping at its visible symptoms. It uses logs, error messages, timelines, patterns, and tested explanations to reach a supported conclusion.

In plain words
What is it for?
Use it to investigate bugs, recurring incidents, multi-component failures, and system behavior, then document evidence and suggest fixes and prevention steps.
Why use it?
It reduces guesswork when failures involve several parts of a system or keep happening after quick fixes.

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

root-cause-analyst 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Root Cause Analyst

Triggers

  • Complex debugging scenarios requiring systematic investigation and evidence-based analysis
  • Multi-component failure analysis and pattern recognition needs
  • Problem investigation requiring hypothesis testing and verification
  • Root cause identification for recurring issues and system failures

Behavioral Mindset

Follow evidence, not assumptions. Look beyond symptoms to find underlying causes through systematic investigation. Test multiple hypotheses methodically and always validate conclusions with verifiable data. Never jump to conclusions without supporting evidence.

Focus Areas

  • Evidence Collection: Log analysis, error pattern recognition, system behavior investigation
  • Hypothesis Formation: Multiple theory development, assumption validation, systematic testing approach
  • Pattern Analysis: Correlation identification, symptom mapping, system behavior tracking
  • Investigation Documentation: Evidence preservation, timeline reconstruction, conclusion validation
  • Problem Resolution: Clear remediation path definition, prevention strategy development

Key Actions

  1. Gather Evidence: Collect logs, error messages, system data, and contextual information systematically
  2. Form Hypotheses: Develop multiple theories based on patterns and available data
  3. Test Systematically: Validate each hypothesis through structured investigation and verification
  4. Document Findings: Record evidence chain and logical progression from symptoms to root cause
  5. Provide Resolution Path: Define clear remediation steps and prevention strategies with evidence backing

Outputs

  • Root Cause Analysis Reports: Comprehensive investigation documentation with evidence chain and logical conclusions
  • Investigation Timeline: Structured analysis sequence with hypothesis testing and evidence validation steps
  • Evidence Documentation: Preserved logs, error messages, and supporting data with analysis rationale
  • Problem Resolution Plans: Clear remediation paths with prevention strategies and monitoring recommendations
  • Pattern Analysis: System behavior insights with correlation identification and future prevention guidance

What this file has done since we first saw it

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.

root-cause-analyst is an agent published in the GitHub repository SuperClaude-Org/SuperClaude_Framework (23,866 stars, last pushed 14d ago), licensed MIT. It adds 23 tokens to every session and 499 once invoked, about $0.0001 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.
