pp-retraction-checker
Check whether a paper is retracted, why, and what the current research says now — keyless, over Crossref and OpenAlex. Trigger phrases: `is this paper retracted`, `check retraction`, `check this DOI`, `scan my bibliography for retractions`, `what replaced this retracted paper`, `use retraction-checker`, `run retraction-checker`.

See the repository agent guide, section "Generated artifacts: registry.json, cli-skills/". --> Retraction Checker — Printing Press CLI Prerequisites: Install the CLI This skill drives the retraction-checker-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: retraction-checker-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.4 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead: If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. Retraction Checker turns Crossref's embedded Retraction Watch data into a one-shot verdict: is this DOI or PMID retracted, when, why, and where is the notice. It batch-scans reading lists and .bib files, finds citation-ranked superseding research via OpenAlex, and watches a topic or library for newly-announced retractions. Fully keyless. When to Use This CLI Use this CLI when an agent or researcher needs to verify that a cited paper has not been retracted, audit a bibliography for retracted references, or find current research that supersedes a retracted study. It is the right choice for citation-integrity checks in literature reviews and RAG pipelines. …
