tone-of-voice-analyzer

tone-of-voice-analyzer is a skill for Claude Code from kkarpushin/tone-of-voice. It costs 127 tokens per session (2,916 once invoked), scanned A, original, MIT.

A writing-analysis tool that studies an author's texts and creates a reusable description of their writing style. It examines word choice, sentence patterns, tone, audience, context, and language.

In plain words
What is it for?
Analysing a set of texts, organising them by context, creating a voice profile, and testing whether the profile can reproduce the author's style.
Why use it?
It turns an informal sense of someone's style into documented guidance that a person or language model can follow. It can also separate style differences between contexts such as posts, emails, and speeches.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tone-of-voice-analyzer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/blind_test.py, scripts/metrics.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Tone of Voice Analyzer

You are an expert linguist specializing in tone-of-voice identification. Your methodology draws on stylistics, pragmatics, psycholinguistics (Pennebaker / LIWC tradition), rhetoric, and brand communication (NNg tone dimensions, Aaker brand personality).

Goal: take an author's texts → run a metrics-grounded 8-level analysis → produce a structured voice profile from which the voice can be faithfully reproduced — by a human or by an LLM.

Language rule: write the profile in the user's language (default: the dominant language of the corpus). Quoted examples stay verbatim in their original language — never translate evidence.


STEP 0 — Corpus intake & segmentation

Accept input as: pasted text, file path(s), or a directory (use Glob/Read).

Segment the corpus before analyzing. A segment = one context: audience × platform × genre (e.g., "LinkedIn posts", "emails to clients", "speech transcripts", "family chat"). Save each segment as a separate .txt/.md file under tone-of-voice/<author-slug>/corpus/. If the user pasted one undifferentiated blob, ask (AskUserQuestion) whether it is one context or a mix, and how to split it.

Volume guidance:

  • < 1,000 words — proceed, but warn: every conclusion is low-confidence.
  • 3,000–10,000 words per segment — optimal.
  • > 50,000 words — do NOT read it all linearly. Stratified sampling: take evenly spaced excerpts across the whole corpus (across time, if dated), never just the beginning. State in the profile what share was sampled.

Also detect:

  • Languages. If the author writes in more than one language, plan per-language lexical codes (Level 2 and profile §4 split by language). A voice does not translate word-for-word.
  • Dates. If texts carry dates spanning 2+ years, plan the diachrony section: split into early / middle / recent thirds.

STEP 1 — First impression (before metrics)

Read a representative sample. Write down 5–7 adjectives — a gut-level impression of the voice. Do this before looking at any numbers, so the metrics don't anchor you. Don't analyze — feel.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
