r-util-lib-sync SKILL.md skillA
r-util-lib-sync from rfxn/rdf is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add rfxn/rdf/r-util-lib-sync@git:20260902.42a192dPins git:20260902.42a192d in mdr.lock. Pin the fingerprint instead.

Cross-project shared library drift detection. Compares canonical library.
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
Cross-project shared library drift detection. Compares canonical library sources against all consumer copies. Report mode by default; optional sync mode copies and verifies. ## Arguments - `$ARGUMENTS` — optional: `--sync` to execute copy operations (default: report only) ## Setup Read `.rdf/governance/index.md` to identify: - Shared libraries used by this project (from governance/architecture.md or by scanning for library version variables) - Canonical source locations for each library - Consumer paths within the project If governance does not specify library locations, fall back to scanning for files with `_LIB_VERSION=` patterns to identify shared libraries. ## Step 1: Detect Context - If CWD is a project directory, check only that project's library copies - If CWD is a workspace root, check all projects under it For each project, determine which libraries it consumes by checking for the presence of library files. ## Step 2: Compare For each canonical-to-consumer pair: 1. **Checksum**: `sha256sum` both files, compare 2. **Version**: Extract version variable from both and compare 3. **Status**: SYNCED (identical checksum) or DRIFTED ## Step 3: Drift Report …

How to install
mdr add rfxn/rdf/r-util-lib-sync@sha256:934158c5de090832The 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.
