👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

Reviewer's GuideRestructures proxy-related rate-limiting behavior to read trusted proxy configuration dynamically from environment, adjusts security and rate-limit tests to patch those environment variables deterministically, and performs repo hygiene by moving utility scripts back under backend/scripts and normalizing TODO comments to the structured schema across docs, notebooks, and scripts.

There was a problem hiding this comment.
Hey - I've left some high level feedback:
- In
extract_client_ip_from_forwarded, mutating the globalTRUSTED_PROXIESon each call based onos.getenvintroduces hidden shared state and potential cross-request interference; consider deriving the trusted proxy set as a local variable (or via an injected/config object) rather than updating the module-level global. - The new
trusted_proxy_count == 0special case that returnsips[-1]can raiseIndexErrorifipsis empty and subtly changes previous semantics; it would be safer to guard for emptyipsand document/centralize the behavior for the zero-proxy case so callers understand when the last IP is used. RateLimitMiddleware.dispatchnow importsagent.securityand readsTRUSTED_PROXY_COUNTfrom the environment on every request; you could avoid per-request imports/env parsing by passing the proxy count into the middleware at construction time (or caching the dynamic value) while still keeping tests configurable.

Please address the comments from this code review:
## Overall Comments
- In `extract_client_ip_from_forwarded`, mutating the global `TRUSTED_PROXIES` on each call based on `os.getenv` introduces hidden shared state and potential cross-request interference; consider deriving the trusted proxy set as a local variable (or via an injected/config object) rather than updating the module-level global.
- The new `trusted_proxy_count == 0` special case that returns `ips[-1]` can raise `IndexError` if `ips` is empty and subtly changes previous semantics; it would be safer to guard for empty `ips` and document/centralize the behavior for the zero-proxy case so callers understand when the last IP is used.
- `RateLimitMiddleware.dispatch` now imports `agent.security` and reads `TRUSTED_PROXY_COUNT` from the environment on every request; you could avoid per-request imports/env parsing by passing the proxy count into the middleware at construction time (or caching the dynamic value) while still keeping tests configurable.Help me be more useful!
