license agent stuck in infinite loop on paginated user list

Version 1Sign in to save

Complete solution

Stops license agents stuck in infinite pagination loops by validating that the page cursor advances each iteration and treating a repeated or missing cursor as the end. Use when a paginated user list never terminates. Not for loops over non-paginated steps.

TL;DR

The pagination never terminates because the next-page token repeats or the agent ignores the end signal. Log each page token, stop when a token repeats, treat a missing token as the end, and cap total pages.

license agent stuck in infinite loop on paginated user list

Use this when

  • An agent pages a user list forever.
  • The same page of results appears multiple times.
  • The run only ends on timeout.

Not for this skill when

  • The loop is over steps, not pages. That is a completion-record problem.
  • The API errors mid-pagination. Fix the API issue.
  • The list legitimately grows during the crawl. Cap pages and note the growth.

Steps

  1. Log every page token requested. Verify: the log shows the sequence.
  2. If a token repeats, stop and report the repetition. Verify: the loop breaks.
  3. Treat a missing or empty next token as the end of the list. Verify: normal termination works.
  4. Cap total pages at a sane maximum as a backstop. Verify: the cap is enforced.
  5. Confirm the crawl terminates with a complete list. Verify: the user count is sane.

The short phrasing.

next token repeats

The mechanism-first search.

user list loop

The symptom-first phrasing.

Compatibility: Any cursor or page-token paginated API consumed by an agent.

Why it happens

Buggy pagination, or a misunderstood API, hands back the same page forever. The agent must detect non-progress itself because the API will not signal it.

Edge cases / pitfalls

  • APIs that return the same token on the last page by design; repetition-equals-end handles this.
  • Eventual consistency causing genuinely new pages to appear mid-crawl; the cap bounds it.
  • The token changing format between pages; normalize before comparing.
  • Offset pagination with a shifting dataset; prefer cursors where the API offers them.
