codexqa-rootcause-analyzer SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
codexqa-rootcause-analyzer from openqa-cn/openqa-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add openqa-cn/openqa-skills/codexqa-rootcause-analyzer@v0.0.1Pins v0.0.1 in mdr.lock. Pin the fingerprint instead.

Diagnoses exception root causes from stack traces, logs, call-chain dumps, and debug output using the CodexQA CLI for structured repo analysis. Use when the user mentions codexqa-rootcause-analyzer, exception RCA, crash analysis, AI code diagnosis, stack diagnosis, 异常根因, 堆栈诊断, 崩溃分析, 异常诊断, or asks to turn an exception into a root-cause report. Not structure/impact analysis (that is codexqa-code-analyzer), not SAST + Agent LLM Detection code-risk scan reports (that is codexqa-defect-analyzer)…
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 Diagnosis
Turns exception evidence into an **English** root-cause report. Structured understanding of the business codebase comes from the CodexQA CLI; this skill diagnoses **on top of** that analysis.
CLI: `node {baseDir}/scripts/diagnose.ts` (`$SKILL_SCRIPT`). Task data: `{baseDir}/data/{taskId}/`.
`README.md` / `README.zh-CN.md` / `HOW_IT_WORKS.md` / `KNOWN_LIMITATIONS.md` (and their `.zh-CN` twins) are human-facing. Do not load them at runtime.
## Boundaries
| Need | Skill |
|---|---|
| Symbol-graph change impact, callers, test gaps, entry risk | `codexqa-code-analyzer` |
| Exception RCA from stacks/logs on top of CLI analysis | **this skill** |
| SAST + Agent LLM Detection → `report_scan.*` | `codexqa-defect-analyzer` |
| CodexQA evidence-pack + Agent LLM judgment → bilingual `REVIEW-REPORT.html` | `codexqa-code-reviewer` |
## Split of work
| Layer | Owns |
|---|---|
| TypeScript (`draft-report`) | First-level English headings, extracted facts (`facts.json`), mechanical `storyGaps` |
| Model | Report narrative inside those headings, using only cited facts |

How to install
mdr add openqa-cn/openqa-skills/codexqa-rootcause-analyzer@sha256:db3857e16a14e267The line at the top of this page pins the label v0.0.1, 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.
