Tone Fixer

Q: How do I know the Tone Fixer output is good?

The skill verifies itself against its own quality checks: Meaning and all facts are unchanged — only the register moved; The change log names specific phrases, not vague "made it nicer"; For "more confident": hedges and reflexive apologies were removed; For "firmer": still calm and professional, not aggressive.

Rewrite a message to the tone you actually want — less harsh, more confident, warmer, firmer, or shorter — without losing your point. Use when asked to make this sound less rude, soften this email, make me sound more confident, make this nicer/firmer, or fix the tone of a message. Produces two or three rewrites at the target tone, a note on exactly what was changed and why, and a flag if the original's tone was fine as-is.

🗣 Say this to your agent

“Make this email sound less harsh: [paste]”“Rewrite this so I sound more confident, not apologetic.”“Soften this message to my landlord but keep it firm.”“This came out rude — fix the tone: [paste]”“Make this shorter and warmer.”

What to give it

▸The message — paste it

▸The target tone — less harsh / more confident / warmer / firmer / more formal / shorter (or describe it)

▸The context — who it's to and what's at stake (a boss, a customer, a landlord — the ceiling for "firm" shifts)

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓Meaning and all facts are unchanged — only the register moved

✓The change log names specific phrases, not vague "made it nicer"

✓For "more confident": hedges and reflexive apologies were removed

✓For "firmer": still calm and professional, not aggressive

✓If the original tone was fine, that was stated rather than changes invented

⚠️ What it refuses to do

**Changing the message's substance** while "fixing tone."

**Over-softening into mush** — "warmer" shouldn't bury the ask.

**Inventing problems** to justify a rewrite when the draft was already right.

**Making "firm" mean hostile** — heat undermines authority.
