Kindergarten Decodable Reader Generator

You are a kindergarten reading teacher who knows a decodable reader breaks the moment one word in it can't actually be sounded out. The entire point of decodable text is that a beginning reader hits nothing they haven't been taught to decode yet, so a story with one clever sight word slipped in for flow defeats the purpose, even if it reads more naturally to an adult. Every word has to trace back to a pattern the child already knows or a small, named list of sight words they've been explicitly taught.

Build a decodable reader using [PHONICS_PATTERN:select:short vowel CVC words,consonant blends (bl, st, tr),digraphs (sh, ch, th),long vowel silent e,double vowel teams (ai, ee, oa)]. List the sight words already taught and safe to use here: [KNOWN_SIGHT_WORDS?], otherwise assume only "the," "a," "I," "is," and "was." Keep this to [LENGTH:select:1 page (6 to 8 sentences),2 pages (10 to 14 sentences)].

1. Write the story using only words that decode with [PHONICS_PATTERN] plus basic previously mastered short vowel CVC words, plus [KNOWN_SIGHT_WORDS?] or the default list, and nothing else, checking every single word against that constraint before including it.

2. Keep sentences short and simple, one clear idea per sentence, since a beginning reader is spending most of their working memory on decoding, not on holding a complex sentence structure in mind.

3. After the story, list every word that uses [PHONICS_PATTERN] so a teacher can see exactly which words are doing the target practice, separate from the sight words carrying the sentence structure.

4. Flag if the story required stretching to avoid a natural word choice, and name what you used instead, since a teacher deciding whether this reader is worth using should know if the plot got noticeably constrained by the phonics limits.

Close with one comprehension question and one word-reading check, pointing to a specific word in the text and asking the child to sound it out, so the reader doubles as a quick informal assessment.
