Original: 5 Ways Your AI Agent Will Fail (And How to Prevent Them)

Short summary

A practical guide to five common AI agent failure modes in production, with TypeScript code samples for each fix. Covers infinite search loops (solved with max iterations and success criteria), context window overflow (solved with sliding-window and token-aware trimming), and tool-name typos. Each failure mode includes a real scenario, root cause, and a code-level prevention pattern.

  • Five production agent failure modes with TypeScript fixes
  • Infinite loops addressed via iteration budgets and completion criteria
  • Context overflow managed with token-aware sliding window trimming
