Change-impact analysis for one diff: use CodexQA diff indexing (`index --diff-base` tags nodes and files `add` / `change` / `delete`, then `change-groups` / `symbol-diff` / `file-base`) to write one HTML report (affected entries, changed methods, test plan, coverage verdict, sensitive paths) and add runnable test files in the analyzed repo for uncovered points (add only; do not edit existing test files). Use when the user mentions change impact, change analysis, blast radius, affected entries…
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
# Change Impact Analysis One sentence: build a **trusted diff index**, then deliver two artifacts — a 7-section HTML report (key findings / risks and unknowns / affected entries / change list / test plan / coverage verdict / sensitive paths) plus **runnable test files** for points that are not covered. `codexqa` has **no** `diff` or `review` subcommand. Change analysis always follows this path: ```text index --diff-base <base> --full → change-groups / files --change → symbol-diff → reach --direction in (entries) → tested_count / reach --edge-kinds tests → test-file text recall ``` ## Deliverables (both required) | ID | Deliverable | Form | |---|---|---| | A | **HTML report**: key findings / risks and unknowns / affected entries / change list / test plan / coverage verdict / sensitive paths | **One self-contained HTML file** at the repo root: `change-impact-<repo-slug>-YYYYMMDD-HHMM.html` | …

How to install
mdr add openqa-cn/codexqa/codexqa-change-analysis@sha256:c120d31506da7e1eThe line at the top of this page pins the label v1.0.0, 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.
