Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# LinkedIn Post Formatter Transform raw content, ideas, or technical material into polished, engagement-optimised LinkedIn posts using Unicode typography and proven structural patterns. ## Overview LinkedIn only supports plain text — no Markdown rendering, no rich formatting. This skill uses Unicode Mathematical Alphanumeric Symbols to simulate bold, italic, and bold-italic text that renders natively in the LinkedIn editor without any external tools. ## Unicode Typography Reference When converting plain text into Unicode-styled LinkedIn text, first load and use `references/unicode-charmap.md` as the authoritative character mapping reference. Apply these character mappings to create visual emphasis in plain text: ### Bold (Mathematical Sans-Serif Bold) Use bold for key phrases, section headers, and emphasis words. | Plain | Unicode Bold | |-------|-------------| | A-Z | 𝗔-𝗭 | | a-z | 𝗮-𝘇 | | 0-9 | 𝟬-𝟵 | ### Italic (Mathematical Sans-Serif Italic) Use italic for subtle emphasis, technical terms, or quotes. | Plain | Unicode Italic | |-------|---------------| | A-Z | 𝘈-𝘡 | | a-z | 𝘢-𝘻 | …

How to install
mdr add marielynneblock/arcanum-artifex/linkedin-post-formatter@sha256:c625c82d5623edb6The line at the top of this page pins the label git:20260710.0115f49, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
