What Voice Extract is

Voice Extract is a slash command published in the athola/claude-night-market repository on GitHub, which has about 339 stars. The repository describes itself as: “23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context optimization, research, and multi-LLM delegation. 186 skills, 128 commands, 54 agents.”

A slash command is a reusable prompt saved as a markdown file and run by typing its name after a slash. In Claude Code, custom commands have been merged into skills: a file in .claude/commands/ and a skill folder in .claude/skills/ both create the same kind of command, and existing command files keep working.

Voice Extract gives you a repeatable way to run the same instructions without retyping them, optionally with arguments.

How to install Voice Extract

Claude Code

Download voice-extract.md from the repository.
Save it to ~/.claude/commands/ (all projects) or .claude/commands/ (one project). As a skill, you can instead save it as ~/.claude/skills/<name>/SKILL.md.
Run it by typing / followed by its name.

Claude Cowork

Turn the command into a skill: create a folder with the file saved as SKILL.md and zip it.
In Customize → Skills, click +, then upload the ZIP.
Run it from any task with / and the skill name.

Extract a voice profile from writing samples using SICO comparative analysis.

Usage

# From a directory of samples
/voice-extract myvoice --samples-dir ~/writing-samples/

# Interactive mode (paste samples one at a time)
/voice-extract myvoice

What This Does

Collects writing samples (directory or interactive paste)
Anonymizes samples (strips context labels)
Generates Claude's baseline output on matched topics
Runs SICO Pass 1 (broad comparative extraction)
Runs Pass 2 (pressure test for specificity)
Creates voice profile at ~/.claude/voice-profiles/{name}/
Generates default register

After Extraction

Review the extraction: cat ~/.claude/voice-profiles/{name}/extraction.md
Generate in voice: /voice-generate {name}
Add more samples later: /voice-extract {name} --add

Skill Invocation

Skill(scribe:voice-extract)

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
