ru-score

ru-score is a skill for Claude Code, Codex from talkstream/ru-text. It costs 75 tokens per session (1,410 once invoked), scanned A, original, MIT.

A checker that gives Russian text a score from 0 to 10 in five areas: typography, clear language, grammar, structure, and precision for the reader.

In plain words
What is it for?
Use it to score Russian text, assess how clear and correct it is, or compare the quality of different drafts.
Why use it?
It provides one overall number when you need to judge the quality of Russian writing instead of receiving a list of editing suggestions. It does not edit files.

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

ru-score 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 3d ago.

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.

Russian Text Quality Score

Score the text provided in $ARGUMENTS (or the most recent Russian text output if no arguments) using the ru-text scoring rubric.

Procedure

Where the reference files live

This skill reads the corpus that ships with the ru-text skill, which is installed alongside it. Locate that folder once, then read the named files from it:

  • Look for a directory named references whose parent directory is named ru-text, and which contains info-style.md. Every file named below sits in that folder.
  • Search with file tools, never with a shell. Glob on a pattern like **/ru-text/references/info-style.md, or whatever file search the host offers, then Read. This command has no use for a command line: Bash is on its disallowed-tools list, and hosts that do not implement that field still refuse it — measured in Claude Cowork on 12.08.2026, where an opening ls returned «Permission to use Bash has been denied» in red before the search found the corpus anyway. The call bought nothing and cost the reader a scare.
  • In Claude Code the plugin root is also available directly, which saves the search.
  • Do not guess a path. If the folder cannot be found, say so and stop — a check run against remembered rules instead of the corpus is not this command, and reporting one as the other is the failure this whole product exists to prevent.
  1. Load rubric — read scoring.md for the full rubric with anchors.

  2. Determine domain — identify whether the text is UI/interface, business email, article, or general:

    • UI text → also load ux-writing.md for the Reader Precision dimension
    • Business email → also load business-writing.md for the Reader Precision dimension
    • General → use info-style.md only
  3. Evaluate each dimension separately — score in this order:

    • T — Типографика (weight 0.15): quotes, dashes, spaces, special characters per typography.md
    • Ч — Чистота языка (weight 0.25): stop-words, bureaucratic language, clichés, passive voice per info-style.md + anti-patterns.md
    • Г — Грамотность (weight 0.20): punctuation, agreement, tautology per editorial-grammar.md + editorial-punctuation.md
    • С — Структура (weight 0.20): logical flow, paragraphs, transitions, heading use per info-style.md structure section + addenda.md
    • Ц — Точность для читателя (weight 0.20): facts, evidence, reader benefit, actionability per domain rules

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.
