Cellar is a developer CLI that looks up the public API of JVM dependencies (Scala 3/2 and Java). It returns type signatures, members, docstrings and optionally source code as Markdown. Works both against a project's classpath (auto-detects Mill, sbt, scala-cli) and arbitrary published Maven coordinates.
Use Cellar when you need to quickly inspect types or methods from a dependency without opening your IDE or reading source repos: ad-hoc lookups, code review, writing bindings, or debugging type/signature mismatches. It is useful in CI scripts, editor integrations, and terminal-first workflows.
Best fit for developer tooling and CLI-oriented agents (Code assistants, terminal-integrated agents, editor plugins).
Cellar is a CLI tool for inspecting public APIs of JVM artifacts (Scala/Java), returning signatures, members, docs, and source code as Markdown. The SKILL.md is well-written with clear commands, examples, and a logical workflow. The bundled script is a non-portable shell wrapper with a hardcoded path to the author's local machine, making it unusable as-is. The skill is valuable for JVM developers but requires installing cellar separately via nix or binary download.
java (JVM required for cellar)SKILL.md is solid — good structure, clear examples, progressive workflow (search→list→get→source). The bundled script is essentially a dev convenience wrapper with zero portability. Real value comes from the cellar CLI tool itself which must be installed separately. The source_url in the DB may point to root SKILL.md which 404s — actual path is skills/cellar/SKILL.md. No security concerns. Score penalties mainly for the non-functional bundled script and missing frontmatter fields.
