cljs-upgrade

cljs-upgrade is a skill for Claude Code, Codex from brackendev/clojurescript-skills. It costs 33 tokens per session (2,308 once invoked), scanned A, original, MIT.

A dependency-upgrade helper for ClojureScript projects. ClojureScript is a version of Clojure that compiles to JavaScript, and deps.edn is the file that records project dependencies.

In plain words
What is it for?
Use it to upgrade the ClojureScript dependency, refresh dependencies, run the project's compile check, or report the current and latest versions without changing files.
Why use it?
It updates ClojureScript to the newest released version and checks that the project still compiles.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cljs-upgrade scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Upgrade ClojureScript

Upgrade the org.clojure/clojurescript dependency in deps.edn to the latest released version on Maven Central and verify the project still compiles. See the package's CONVENTIONS.md for the argument grammar this skill follows.

Arguments

Input Target
(no argument) Upgrade org.clojure/clojurescript :mvn/version in deps.edn, apply the mechanical changes that the release notes require, and run the advanced-compile build to verify
all Same as (no argument); accepted for family consistency
--report Print the current :mvn/version, the latest released version from Maven Central, and the release-note changes that affect the project, without writing deps.edn, editing files, or running the compile

The skill rewrites a single dependency in deps.edn. <path> rows are not part of the standard scope vocabulary for this skill because the target is fixed.

Mutation

Mutates deps.edn by default, replacing the :mvn/version value under org.clojure/clojurescript. Also runs clojure -P to refresh dependencies and the project's advanced-compile build (clojure -M:build if defined, otherwise clojure -M -m cljs.main --optimizations advanced --compile <main-ns>), which writes generated JavaScript under out/ or the project's compiler :output-dir (build artifact). When the release notes between the two versions require a change to the project's build configuration or source, the skill applies it before compiling and lists it in the report. On compile failure, the skill reverts :mvn/version to the recorded original value and undoes those release-note changes. The skill also runs clj-kondo --copy-configs --dependencies to refresh cached exports under .clj-kondo/imports/. With --report, the skill writes nothing and runs no compile or import refresh. It still fetches the latest version and reads the release notes.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
