What it does

Writing Dna Discovery is an agent skill from robertguss/claude-code-toolkit. Capture a writer's voice DNA through collaborative interview and sample analysis. Use when someone wants to document their writing voice for use with a ghost writer skill. Produces a Voice DNA Document with patterns, anti-patterns, and actionable guidance. Handles one register/mode per session, supports refinement over time.

Its SKILL.md is about 3.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files and assets (for example `assets/templates/voice-dna-template.md`, `references/anti-ai-patterns.md` and `references/dna-document-examples.md`).

It sits in Writing & Content. The repository describes itself as: A collection of custom skills that extend Claude's capabilities with specialized workflows, methods, and domain knowledge.

When your agent uses it

  • Someone wants to document their writing voice for use with a ghost writer skill

Example prompts

  • “/writing-dna-discovery”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. What register/mode are we capturing? (blog, fiction, technical, etc.)
  2. Do they have writing samples to share?
  3. What's their goal? (general capture vs. specific project)
  4. Any influences or writers they identify with?

What it can do on your machine

Read from SKILL.md and the folder at commit f7fd35e. 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

Writing Dna Discovery loads about 3.7k tokens when it runs, and up to ~28k if it reads all its reference files. Until then it costs about 87 tokens; SKILL.md has 1,721 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~3.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~28k

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.

SKILL.md

Its licence (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,721 words (~3,697 tokens).
