D5 Context Management & Reliability · Paper 1

A documentation generation pipeline uses Claude Code to produce docs from three sources: source code comments, existing wiki pages, and API schema files. During a run, the wiki page retrieval fails with a timeout, but the source code and API schema are available. The pipeline currently halts entirely on any source failure. What is the best error handling strategy?

• A.Retry the wiki retrieval three times with exponential backoff. If all retries fail, halt the pipeline to prevent incomplete documentation
• B.Return structured error context for the wiki failure, proceed with available sources, and mark the gaps that lack wiki content.
• C.Silently skip the wiki source and generate documentation from the remaining two sources without noting the omission
• D.Use the source code comments to infer what the wiki pages would have contained, filling in the gaps with generated content

Show answer & explanations

Correct answer: B

A: Halting the entire pipeline because one of three sources is unavailable wastes the successful results from the other two sources. Documentation from source code and API schemas is still valuable even without wiki content.

B: This produces maximum value from available sources while maintaining transparency about what is missing. Structured error context enables intelligent recovery (retry later, alert the team). Explicit gap markers prevent users from trusting incomplete documentation as complete.

C: Silent omission hides the failure. Users would trust the documentation as complete, not knowing that wiki- sourced context (which may contain critical operational notes or caveats) is missing.

D: Inferring wiki content from source code produces hallucinated documentation that appears authoritative. Wiki pages often contain operational context, known issues, and tribal knowledge that cannot be inferred from code.
