parinfer-cljs

name	parinfer-cljs
description	Auto-fix Clojure/ClojureScript bracket mismatches using parinfer indentMode. Use when writing or editing .clj, .cljs, or .cljc files, working on ClojureScript code, or after any file modification to Clojure source. Do NOT use for non-Clojure files.

parinfer-cljs

Fix bracket/parenthesis mismatches in Clojure and ClojureScript files using parinfer's indentMode, which infers correct bracket structure from code indentation.

Instructions

After Every Write or Edit to a .clj/.cljs/.cljc File

Run parinfer on the modified file:

node <skill-dir>/scripts/parinfer-fix.mjs <file-path>

Where <skill-dir> is the directory containing this SKILL.md.

Batch Mode

Multiple files at once:

node <skill-dir>/scripts/parinfer-fix.mjs file1.cljs file2.cljs file3.cljc

All files in a directory:

find packages/kernel-cljs/src -name "*.cljs" | xargs node <skill-dir>/scripts/parinfer-fix.mjs

Output

Output	Meaning
OK <file>	Brackets already correct, no changes
FIXED <file>	Brackets were wrong, file updated in place
FAIL <file>	Could not fix — manual intervention needed
SKIP <file>	Not a .clj/.cljs/.cljc file, ignored

How It Works

parinfer indentMode trusts your code's indentation and derives the correct bracket structure from it. AI-generated Clojure is typically well-indented even when brackets are wrong — exactly the input indentMode is optimized for.

Important

• Run parinfer AFTER writing/editing, not before
• This does not replace clj-kondo — run kondo separately for semantic checks
• Non-.clj/.cljs/.cljc files are automatically skipped

Examples

Example 1: Fix after writing a new file

User says: "Create a new CLJS namespace for session management" Actions:

1. Write the .cljs file
2. Run node <skill-dir>/scripts/parinfer-fix.mjs packages/kernel-cljs/src/pi/kernel/session_mgmt.cljs Result: OK or FIXED — brackets guaranteed balanced

Example 2: Fix after editing existing code

User says: "Add error handling to the provider interceptor" Actions:

1. Edit the .cljs file
2. Run node <skill-dir>/scripts/parinfer-fix.mjs packages/kernel-cljs/src/pi/kernel/interceptors/provider.cljs Result: Any bracket mismatches from the edit are auto-corrected

Example 3: Batch verify after large refactor

Actions:

1. Complete refactoring across multiple files
2. Run find packages/kernel-cljs/src -name "*.cljs" | xargs node <skill-dir>/scripts/parinfer-fix.mjs Result: All files checked and fixed in one pass

Troubleshooting

Error: FAIL <file>: unclosed-paren at line N Cause: Indentation is also broken, so parinfer can't infer correct brackets. Solution: Fix the indentation at the reported line, then re-run.

Error: FAIL <file>: unmatched-close-paren at line N Cause: Extra closing bracket with no matching opener. Solution: Remove the extra bracket at the reported line, then re-run.
