Extract a house style guide from your own writing

Analyze these writing samples that I own or may reuse:
Sample A: Start with one shelf. Put the tools you use every week where you can reach them. The rest can wait.
Sample B: A useful plan fits the day you actually have. Choose the next small action, then leave room for interruptions.
The guide will be used for Short practical articles for a community workshop newsletter. Keep these preferences: Warm but direct; retain short paragraphs; avoid forced jokes and motivational slogans.

Identify recurring choices in tone, sentence length, vocabulary, point of view, paragraph structure, punctuation, and use of examples. Support each important observation with a short excerpt or sample reference. Separate consistent patterns from features that appear only once or depend on the subject.

Create a concise house style guide with do/avoid pairs, five editing checks, and a reusable instruction block for future drafts. Do not copy distinctive sentences into that block or carry facts from the samples into unrelated writing. Note where the small sample is insufficient to establish a rule. Describe observable techniques rather than claiming to reproduce a named author's identity or personality.
