**Level:** Starter

## Skills

| Skill | Trigger | Output | Guardrail |
|---|---|---|---|
| reader-brief | Before any draft longer than a paragraph | One named reader, their decision, what they already know and what they must not have to re-read | A brief with more than one reader is split, not averaged. |
| voice-matcher | When a draft must sound like an existing writer or brand | A short style card: sentence length, vocabulary, what the voice never does, and three before/after examples | The skill copies patterns, not sentences, and never invents a quote. |
| claim-checker | Before publishing anything with a number, date, rule or quote | Each claim labelled fact, opinion, experience or unknown, with the source sentence | An unsupported claim is removed or flagged, never rounded into confidence. |
| repurpose-kit | When one finished piece must become several formats | A channel map with the same claim, a format-specific hook and the link back to the original | A short post may compress the claim; it may not strengthen it. |

## Install

1. Create `skills/reader-brief/`, `voice-matcher/`, `claim-checker/` and `repurpose-kit/` in the writing project.
2. Put two or three samples of the target voice in `references/` and tell the skill to copy patterns, not sentences.
3. Keep the claim check separate from the rewrite skill. A rewrite that also checks its own claims tends to approve them.
4. Run the tests below on a real draft. If the voice card could describe any writer, it is too generic.

## Tests

- **Prompt:** Rewrite this draft for a solo founder deciding whether to hire a contractor.
  **Pass:** The output names the reader and the decision, and removes at least one paragraph that does not help that decision.
- **Prompt:** Make this sound like the samples in references/ without copying a sentence.
  **Pass:** The style card names three observable patterns and the rewrite contains no verbatim sentence from the samples.
- **Prompt:** Turn this article into a LinkedIn post and an email.
  **Pass:** Both formats keep the original claim and link back; neither adds a number or a promise that was not in the article.

## Why this pack

Writing with an agent goes wrong in two directions: the draft sounds like a model, or it sounds like you and quietly invents a fact. The four skills handle both. The reader brief and voice matcher protect the sound; the claim check protects the substance.

The repurposing kit is the multiplier. One piece of work should become a post, a section of a newsletter and a note to a client — but only if the claim survives the format change.

## The rule behind the pack

The format can change; the claim cannot. A short post may make the same claim with fewer caveats, but it may not make a stronger one. If the caveat is what makes the claim true, the short version is wrong.

## Adapting it

- For a team blog, add an approval step and a house style list to `voice-matcher`.
- For client copy, add the client's legal wording to `claim-checker` as uneditable.
- For a newsletter, make the repurpose kit produce one email and three short posts, not ten.

## Failure modes

- **The voice card is adjective soup.** “Warm, authoritative, human” describes nothing. Ask for sentence length, vocabulary and what the voice never does.
- **The claim check passes everything.** Give it the source list separately; a checker with no sources can only guess.
- **The repurposed post overclaims.** Compare the post's strongest sentence to the original's. If it is stronger, cut it.
