At a glance

Analyze writing samples and extract the patterns that define the user's voice.

  • Train Claude on how they write
  • Make future writing sound like them

What it does

Voice Dna is an agent skill from hamzafarooq/claude-code-starter. Analyze writing samples and extract the patterns that define the user's voice. Use when the user wants to capture their writing style, train Claude on how they write, or make future writing sound like them.

Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Brand voice and tone. The licence is MIT.

When your agent uses it

  • The user wants to capture their writing style
  • Train Claude on how they write
  • Make future writing sound like them

Example prompts

  • “/voice-dna”

What it can do on your machine

Read from SKILL.md and the folder at commit 172c531. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Voice Dna loads about 351 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 168 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~351

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Analyze writing samples and extract the patterns that define the user's voice. Use when the user wants to capture their writing style, train Claude on how they write, or make future writing sound like them.

Ask the user to paste 3–5 samples of their writing (emails, posts, articles, anything they've written).

Analyze the samples and produce:

Voice DNA: [Name]

Tone

One sentence describing the overall register (e.g. "Direct and slightly irreverent — sounds like a senior colleague, not a textbook").

Sentence patterns
  • Average length: [short / medium / long]
  • Structure tendencies: [e.g. "leads with the point, explains after" or "builds to the punchline"]
  • Punctuation style: [e.g. "uses em-dashes, avoids semicolons"]
Vocabulary fingerprint
  • Words/phrases you use often: [list 5–8]
  • Words/phrases you never use: [list 3–5]
  • Formality level: [1–5, where 1 = casual text, 5 = legal brief]
What makes it yours

3 specific stylistic moves that show up across multiple samples. Be precise (e.g. "opens paragraphs with a counterintuitive claim" not "writes engagingly").

What to avoid

3 patterns that would immediately break the voice.

Prompt you can reuse

"Write in my voice: [paste the Voice DNA summary above]. The topic is: [X]."


At the end, ask: "Want me to test this by writing something in your voice right now?"
