dashless

Removes em dashes from what Claude writes, before it lands. About 80 lines of TypeScript.

| Where | What gets fixed | | --- | --- | | Write tool | the file content | | Edit tool | new_string only (old_string must match the file, so it is never touched) | | Bash | only git commit and gh pr / gh issue create, edit, comment; every other command runs as is | | Replies | text blocks in Claude's responses, before they are stored |

Rewrite rules (<code>—</code> is the em dash, <code>–</code> the en dash):

<!-- Dashes in this file are HTML entities on purpose. With literal characters, dashless rewrites its own examples whenever Claude edits this file. -->

| Input | Output | | --- | --- | | <code>a — b</code>, <code>a—b</code> | a, b | | <code>— item</code> at line start | item (indentation kept) | | <code>done —</code> at line end | done | | <code>note: — x</code> | note: x | | <code>a – b</code> (spaced en dash) | a, b | | <code>1990–2000</code> (range) | unchanged | | --force, -- file | unchanged |

The status line shows a running count: dashless: 3 em dashes fixed.

Tested by running the same prompt twice in a throwaway git repo (write a file, commit it, reply with a sentence, each with an em dash). Without the mod 4 em dashes landed; with it, 0.
