Measure your own writing corpus for the words and sentence shapes you over-use, so an agent writing in your voice stops amplifying your tics into a style. Produces a counted baseline file and checks any new draft against it. Use when an agent's drafts start sounding like a caricature of you, before publishing anything written in your voice, or every ten new pieces to re-measure.

  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 1 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by huytieu on GitHub. Read the source before you install it.

Installation

Install the Voice Baseline AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/huytieu/COG-second-brain.git /tmp/COG-second-brain
mkdir -p .claude/skills
cp -r /tmp/COG-second-brain/skills/voice-baseline .claude/skills/voice-baseline
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Voice Baseline in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Voice Baseline on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Voice Baseline is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

voice-baseline

An agent writing in your voice does not only sample the median of the internet. It samples the median of you, from the pieces and rules and memory files in its context, and it regresses toward your most frequent choices because those are the highest probability tokens in your corpus. A word that was a choice at one use comes back at five. Then the fifth use teaches the next draft, and the tic becomes the style.

Generic ban lists cannot catch this, because the words are yours and they are not on anyone's list. Measure instead.

Run it

bash
python3 scripts/census.py PATH/TO/YOUR/WRITING --out voice-baseline.md
python3 scripts/census.py PATH/TO/YOUR/WRITING --check DRAFT.md

The census walks a directory of your own finished pieces and reports word counts with a per-file rate, sentence-shape counts, sentence openers, and heading first words. --check compares one draft against those rates and prints only what sits above them. Exit code 1 when something is above baseline, so it fits a pre-publish script.

Keep the output file next to your rules so the agent reads it before it writes.

What it measures

Words. A watchlist of praise and emphasis words, counted with word boundaries and reported per file. Read the per-file rate: a word used twice per file is a habit, and the same word at eight in one draft is the draft's problem. Edit WATCH in the script to add your own suspects; the point is that the list ends up specific to you.

Paragraph-ending verdict sentences. "The fix was one line." A concrete noun, a past-tense verb, a short predicate, parked at the end of a paragraph so it lands like a ruling. One per piece at most, and only when it carries a fact the paragraph has not already delivered.

Kicker closers. "That is the point." "That is all a title is for." A closing line that restates the piece as an aphorism. The cap is zero.

Endings. How many pieces close on a question to the reader. Most of them means the question has become a formula.

Sentence openers and heading first words. These are where a personal tic hides best, because each instance reads fine. If a third of your headings begin with the same word, you have a template. In one real 27-file archive the census found 53 headings starting with "The", the exact shape people name as an AI tell, learned from the author's own archive.

How to read the result

The census counts; it does not judge. For each flagged word or shape, decide whether it is your voice or your mode:

  • Voice. The word carries meaning the sentence needs, or the rhythm is yours and deliberate. Keep it, and note the exception so the next check does not re-raise it.
  • Mode. The word is praise, emphasis, or padding, and removing it changes nothing for the reader. Cut it, or replace it with the behaviour it was gesturing at.

Fix the shapes by cap rather than by ban: one verdict sentence, zero kickers, no default question ending, one narrative heading pattern per piece.

Re-measure

Run the census again after roughly ten new pieces. A tic you fixed should fall. A new one will have appeared, usually the word you reached for while avoiding the last one, which is the same substitution the model makes when a single word is banned.

Pair with slop-gate for the universal tells and no-ai-slop for the structural ones a regular expression cannot see.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Voice Baseline AI skill do?

Measure your own writing corpus for the words and sentence shapes you over-use, so an agent writing in your voice stops amplifying your tics into a style. Produces a counted baseline file and checks any new draft against it. Use when an agent's drafts start sounding like a caricature of you, before publishing anything written in your voice, or every ten new pieces to re-measure.

Why use Voice Baseline on TypingMind?

Because you install it once and use it with any model. Voice Baseline is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Voice Baseline in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/huytieu/COG-second-brain/tree/main/skills/voice-baseline. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Voice Baseline?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Voice Baseline?

As many as you like. As long as a model supports skills, you can use Voice Baseline with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Voice Baseline AI skill free?

Yes. It is published on GitHub by huytieu under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
