RuWritingStyles: Russian Claude custom styles and an agentic review pipeline for scholarly writing on Sanskrit linguistics

RuWritingStyles is a bilingual resource for scholarly writing on Sanskrit linguistics in Russian. It combines (1) a catalogue of Russian-language Claude custom-style prompts modelled on the prose method of major philologists (Zaliznyak, Tronsky, Mel'čuk, Elizarenkova, Toporov, Lidova and others), and (2) a zero-runtime-dependency agentic review pipeline that runs a multi-style "Council" over a Markdown manuscript (segment, independent style reviews, council deliberation, revision, verification) with deterministic Sanskrit quality checks: IAST/Cyrillic transliteration consistency, GOST R 7.0.100-2018 bibliography formatting, and citation grounding. Review panels are selectable by named council (general / sanskrit / indology). Quality is measured, not assumed: an N-averaged gold-case benchmark (5 Sanskrit gold cases × N=5 runs) shows detection of planted philological errors at 24/25 = 0.96; engine-side span-patch reconstruction with a document-growth budget raised the end-to-end pass rate from 0.48 to 0.92 with zero diff failures. The gold set carries a disclosed two-rater annotation (mechanical scorer vs an independent frontier model, agreement 24/25); the methodology paper draft, the benchmark protocol and all run artifacts are included for reproducibility.
