Epupp Squint

What it does

When your agent uses it

• : editing Squint/ClojureScript in src/
• Testing pure functions via squint-nrepl
• Debugging Squint-to-Scittle message interop
• Avoiding direct .mjs edits

Example prompts

• “/epupp-squint”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

1. 1Use clojure_list_sessions to check available REPL sessions
2. 2Look for a session with "sessionKey": "cljs" - this is the Squint nREPL
3. 3Test connectivity by evaluating a simple expression: (+ 1 2)

What it can do on your machine

Read from SKILL.md and the folder at commit 566ce34. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are clojure).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • github.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Epupp Squint loads about 814 tokens when it runs. Until then it costs about 118 tokens; SKILL.md has 298 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~118

When it runs · the whole SKILL.md, loaded when a task matches

~814

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Epupp-specific Squint source conventions for src/**. Use when: editing Squint/ClojureScript in src/, testing pure functions via squint-nrepl, debugging Squint-to-Scittle message interop, avoiding direct .mjs edits, or rewriting legacy JS interop to Clojure style. For universal Squint semantics (keywords, data structures, async, compilation model) load the universal Squint skill separately. IMPORTANT: Also load when planning changes to src/** Squint code.

;; Scittle side sends {:epupp/inject ["scittle://reagent.js"]}
;; After clj->js, the key becomes "inject" (namespace stripped)
(aget manifest "inject")        ; correct
(aget manifest "epupp/inject")  ; nil - namespace was stripped

;; Test pure functions from url_matching.cljs
(require '[url-matching :refer [url-matches-pattern?]])
(url-matches-pattern? "https://github.com/foo" "*://github.com/*")
;; => true

;; Test storage helpers
(require '[storage :refer [generate-script-id]])
(generate-script-id "My Cool Script")
;; => "my-cool-script"
