What write-concisely does

The skill embeds instructions from William Strunk Jr.'s 1918 book The Elements of Style. It targets human-facing documentation. The rules govern English grammar, focusing on singular possessives and parenthetic punctuation.

Composition principles guide the overall layout. Each topic belongs in its own paragraph with a clear opening sentence. The assistant removes needless words and favors positive, direct phrasing. Emphatic terms go at the end.

The skill also incorporates a list of misused words. Because these conventions reflect formal 1918 English, they will clash with casual modern product copy. For structured technical guides, the rules keep prose disciplined.

What it helps with

  • cut filler words and bloat from English technical documentation
  • convert passive sentences into direct active voice
  • reorganize messy sections into single-topic paragraphs
  • fix comma placement and possessives according to classic style rules

Example prompts for the agent

  • Use the write-concisely skill to edit README.md and trim unnecessary words
  • Rewrite this API overview in active voice following write-concisely rules
  • Review this release announcement using write-concisely guidelines
