Docs and writing: skills, rules and MCP servers
Docs and writing for Claude Code, Codex and Cursor: skills, subagents, rules and MCP servers, from popular to niche.
Docs and writing: READMEs, changelogs, API references, code comments, articles. Skills here set document structure and voice, and the better ones also ban the filler phrases a model adds out of habit. Look for skills with before-and-after examples: they show that the author tested the output instead of only writing the instructions. For READMEs and changelogs a pair works well: a slash command starts the job, a skill sets the format.
