SASVA Code Generation Truncated Mid-Response on Large Files

Problem

When asking SASVA to generate a large source file (long class, big config file, large SQL script, etc.), the response stops partway through the file with no error message. The chat shows the request as "complete," but the generated file is incomplete — missing closing brackets, trailing functions, or the final sections of the requested content.

Symptoms

  • Generated file ends abruptly mid-statement (e.g., an unclosed function, missing closing braces/tags).
  • Chat response appears to finish normally — no visible error, timeout, or "failed" banner.
  • Re-running the exact same prompt sometimes produces a complete file and sometimes truncates again.
  • Larger files (roughly 300+ lines, or very verbose formats like XML/JSON/HTML) are affected more often than short snippets.

Root Cause

Each SASVA chat response is generated against a maximum output-length (token) limit set by the underlying model/model configuration. When the requested file is large enough that the full content would exceed that limit, generation stops at the boundary rather than failing outright — which is why no error is shown to the user.

This is a different failure mode than the truncated tool-call JSON issue covered in "SASVA HTML/Markdown Document (.md) Generation Failure Due to Truncated Tool JSON" (which is about a malformed JSON payload for the file-creation tool call). This article covers plain content truncation due to output-length limits, where the tool call itself succeeds but the requested content is incomplete.

Resolution/Workaround

1. Ask SASVA to continue

  • In the same chat session, reply with: "Continue generating the file from where you left off" or "Continue from <last line/function you see>". SASVA will resume and append the remaining content.

2. Break the request into smaller parts

  • Instead of asking for an entire large file in one prompt, request it in logical sections (e.g., "generate the imports and class definition first," then "now add the remaining methods").
  • For large data/config files, ask SASVA to generate a template/skeleton first, then fill in sections incrementally.

3. Verify the output before relying on it

  • Always open the generated file and check that it ends with a properly closed structure (matching braces/tags, expected final statement) before committing or running it.
  • For code files, run a quick syntax check/linter/build immediately after generation to catch truncation early.

4. Reduce verbosity of the request

  • Avoid asking for excessive inline comments or repeated boilerplate across a large file — this consumes output budget faster and increases the chance of truncation.

Escalation

If truncation happens consistently on files under ~200 lines, or "continue" does not resume correctly, contact sasva_support_in@persistent.com with the prompt used and the point at which generation stopped.
