# Voice

> Learn how a specific person writes, store it as a profile, and write new text in that voice. Builds the profile from samples they actually wrote, grows it every time they correct a draft, and applies it when drafting. Use when the user says "in my voice", "sound like me", "learn how I write", "/voice", or asks for something written that will go out under their name.

# voice

Style matching usually fails the same way. It copies the surface (sentence
length, punctuation habits, a favourite word) and misses the thing that actually
makes writing sound like a person, which is **what they never say**.

A useful voice profile is mostly negative space. Not "uses short sentences" but
"never opens with a compliment", "never says 'excited to'", "will not claim a
tool they have only opened once". Those rules come from corrections, not from
reading samples, which is why this skill is built to grow rather than to be
written once.

## The mechanism, stated plainly

A skill cannot remember anything on its own. This one persists by reading and
writing a file:

```
~/.claude/voice/<person>.md          # default, applies everywhere
.claude/voice/<person>.md            # project-local, wins if both exist
```

Everything below is operations on that file. There is no magic; if the file is
not updated, nothing was learned.

## Mode 1, build the profile

Triggered by "learn how I write", or automatically when asked to write in a
voice with no profile on disk.

**Only use samples the person actually wrote themselves.** This is the rule that
decides whether the profile is any good. Text they approved, edited, or accepted
from an assistant is contaminated with the assistant's voice, and a profile built
from it will drift further from them every cycle. Ask for raw samples: sent
emails, Slack messages, commit messages, notes to themselves. Messy is better
than polished. Six to ten is enough.

Read them and extract, in this order of value:

1. **Prohibitions.** Constructions absent across every sample. If nobody ever
   opens with a greeting-plus-compliment, that is a rule.
2. **Openers and closers.** How they start and end is the most recognisable and
   most frequently botched part of a voice.
3. **Register per context.** How they write to a client is not how they write to
   a friend. Record contexts separately or the profile flattens into an average
   that matches nothing.
4. **Claim discipline.** What they will and will not assert about themselves.
   Some people round up, some round down. Getting this wrong is worse than any
   stylistic miss because it puts words in their mouth.
5. **Vocabulary they own**, and words they visibly avoid.
6. **Mechanics last.** Punctuation, sentence length, paragraph shape. Real, but
   the least of it.

Write the profile with an example beside every rule, quoted from a sample. A rule
without an example gets misread later.

## Mode 2, write in the voice

Read the profile first. Every time. Do not write from memory of the profile,
because memory of a voice drifts toward the assistant's own.

Then draft, and before returning it run the **prohibition list** against the
draft line by line. That check catches more than any amount of trying to sound
like someone.

State which parts you were least sure about. It is more useful than presenting
a uniformly confident draft, because it tells the person where to look.

## Mode 3, learn from a correction

This is the mode that makes the skill worth having, and it is the one that gets
skipped. Every time the person rewrites something you drafted, **that edit is
training data and it expires in about a minute.** Capture it before moving on.

For each meaningful edit:

1. Record what was written, what it became, and the rule that explains it.
2. Generalise carefully. One correction is an instance. Two of the same shape is
   a rule. Do not write a rule from a single edit unless the person stated it as
   a rule.
3. Append to the profile with the date and the correction that produced it.
4. If a new rule contradicts an old one, do not silently overwrite. Keep both
   with their dates and say which now applies. Voices change, and the history is
   how you tell a change from a one-off.

Corrections stated out loud outrank corrections inferred from edits. If someone
says "stop using em dashes", that is a rule immediately, no second instance
required.

## Profile format

```markdown
# Voice profile: <name>
Updated: <date> · Samples: <n> · Corrections: <n>

## Prohibitions
- Never <X>. Corrected <date>: "<what was written>" became "<what it became>".

## Openers and closers
- Opens with <pattern>. Example: "<quote>"

## Register by context
### <context, e.g. writing to a client>
- ...

## Claim discipline
- Will say: ...
- Will not say: ...

## Mechanics
- ...

## Open questions
- Things not yet observed. Ask rather than guess.
```

The Open questions section matters. A profile that pretends to be complete
produces confident wrong output. One that names its gaps produces a question,
which is cheaper than a bad draft.

## Rules

- **Never invent a fact to fit the voice.** Sounding like someone is not licence
  to claim things on their behalf. When a sentence needs a fact you do not have,
  leave a marked gap and ask.
- **The profile is theirs.** Show any rule you add. People are the authority on
  their own voice and will correct a wrong rule instantly, which is cheap. A
  wrong rule left in place quietly poisons every future draft.
- **Do not use the profile to imitate someone who has not asked.** Voice
  profiles are for a person's own writing, or writing they have explicitly asked
  to have drafted for them.
- **Match the register, not the topic.** Someone informal in Slack is not
  necessarily informal in a contract.
- **When the draft has to be good rather than fast, write it plainly first, then
  apply the voice.** Trying to do both at once produces text that sounds like
  them and says nothing.
