The sentence splitter treats every period as a boundary, so 2.5 and $3.99 become separate sentences. This preserves a period between ASCII digits while retaining the existing punctuation rules for dotted words, ellipses and sentences without intervening spaces. Source offsets and token counts use the complete sentence.

Refs #1542 (sentence-splitting half only). The MarkdownChunker offsets are being handled separately in #1543.

I added regressions for the utility and its SentenceChunker, RecursiveChunker and SemanticChunker callers, plus a patch changeset.

Validation on Node 24.19.0:

• All 64 rag runtime tests pass; the new tests fail on the unchanged utility.
• Package CJS/ESM/declaration build and changed-file Biome checks pass.
• Independent checks of both built public exports pass.
• Standalone package typecheck still reports three errors in the existing code-chunker and late-chunker tests. I reproduced the same diagnostics with the original utility; no errors point to the changed source or new tests.

This does not change abbreviation, Unicode-number or leading-dot-number handling. No dependencies or lockfile changed.

Summary by cubic

Fixes the sentence splitter so decimals like 2.5 and prices like $3.99 are no longer split at the period.

Previously every period was treated as a boundary. Now a period between ASCII digits keeps the number intact, while dotted words, ellipses, and sentences without intervening spaces behave as before. Source offsets and token counts use the complete sentence; abbreviation, Unicode-number, and leading-dot-number handling are unchanged. This covers the sentence-splitting half of #1542. Adds regressions for the utility and its SentenceChunker, RecursiveChunker, and SemanticChunker callers, plus a patch changeset for @voltagent/rag.

^{Written for commit bb165a2. Summary will update on new commits.}

Summary by CodeRabbit

• Bug Fixes
  • Sentence splitting now preserves decimal numbers and prices, such as 2.5 and $3.99, within their sentences.

Walkthrough

The RAG sentence splitter now extends sentence matches across periods between digits. Tests cover sentence text, source offsets, token counts, and outputs from sentence, recursive, and semantic chunkers. A patch changeset records the update.

Changes: Decimal sentence splitting

Layer / File(s)	Summary
Sentence splitting and offsets packages/rag/src/utils/text.ts, packages/rag/src/__tests__/utils.spec.ts, .changeset/preserve-decimal-sentences.md	splitIntoSentences extends matches across decimal points between digits and uses the combined match boundaries for segment text. Tests check sentence text, source offsets, and token counts. A patch changeset records the update.
Chunker integration tests packages/rag/src/__tests__/sentence-chunker.spec.ts, packages/rag/src/__tests__/recursive-chunker.spec.ts, packages/rag/src/__tests__/semantic-chunker.spec.ts	Tests check decimal-containing sentence output from SentenceChunker, RecursiveChunker, and SemanticChunker. The semantic test also checks the complete sentence inputs passed to the embedder.

Change: Bug fix

Merge Risk: Minimal · up to bb165

This change keeps decimal numbers and prices intact when text is split into sentences. The scope is small and covered by tests, and no merge-blocking risk was found.

Full details: Title check

Explanation

The title "fix(rag): preserve decimal sentence boundaries" matches the main change. The PR makes the sentence splitter keep periods between ASCII digits (such as 2.5 and $3.99) inside one sentence, and the title names that behavior with the rag package scope. It follows the conventional commit style.

Full details: Description check

Explanation

The description covers the problem, the behavior change, the scope limits, and the validation steps. It also links the related issue #1542 and notes that the MarkdownChunker part is tracked in #1543. It adds regression tests and a changeset, which the template asks for. The template's checklist and the 'What is the current behavior?' and 'What is the new behavior?' headings are not filled in as labeled sections, and the template's 'fixes (issue)' line is not used. The content still covers what the template asks for, so the check passes.

Co-locate these tests with the tested chunkers.

Move each case into the corresponding chunker’s co-located .spec.ts file. This keeps each chunker’s regression coverage beside its implementation.

As per coding guidelines, “Tests should be co-located with the code they are testing, using the same naming convention.”
