Analyze the current diff to recommend which tests to run and map.
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
# /rdf:r-util-test-scope — Test Scope Recommendation Analyze the current diff to recommend which tests to run and map changed functions to their test files. Combines test tier selection with function-to-test impact analysis. Read-only — does not execute tests. ## Arguments `$ARGUMENTS` — optional: - No args: analyze `git diff` (staged + unstaged) - Function name(s): analyze those specific functions - `--full`: show full impact matrix (not just summary) ## Protocol ### Part 1: Test Tier Selection #### 1.1 Classify Change Scope Run `git diff --name-only` and `git diff --cached --name-only` to get all modified files. Categorize each file: | Category | File Patterns | |----------|--------------| | DOCS | README.md, CHANGELOG*, *.md, man/*, docs/* | | CONFIG | conf.*, internals.conf, compat.conf, .ca.def | | CORE | functions*, *.lib.sh, main entry point internals | | CLI | main entry point case dispatcher, help/usage | | INSTALL | install.sh, uninstall.sh, importconf, cron* | | TEST | tests/*.bats, tests/helpers/*, Makefile | | CI | .github/*, Dockerfile*, run-tests.sh | #### 1.2 Determine Test Tier Based on the highest-impact category in the diff: …

How to install
mdr add rfxn/rdf/r-util-test-scope@sha256:c7ee4d79bb556e60The line at the top of this page pins the label git:20260902.42a192d, 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.
