Docs: Clarify litellm-budget-track pipeline (inbound vs outbound) - #851
Conversation
…bound) The doc described litellm-budget-track as an inbound-pipeline plugin and its example config placed it under pipeline.inbound. The plugin is actually direction-agnostic (it implements the generic OnRequest/OnResponse/OnResponseFrame hooks and declares no fixed direction), and the correct pipeline depends on topology: inbound when AuthBridge fronts the LLM endpoint as a reverse proxy, outbound when hosting the agent via 'rossoctl authbridge exec', whose forward proxy runs the outbound pipeline on the agent's egress. In an 'authbridge exec' setup nothing reaches the inbound pipeline, so a plugin left under inbound: records $0 — a common 'it ran but tracked nothing' trap. Add a 'Pipeline placement' subsection at the config example and soften the two 'inbound pipeline' assertions in the title and Use Case to be direction-agnostic.

Describe the zero-traffic outcome accurately.
When authbridge exec uses the outbound pipeline, the inbound plugin does not process a response or write a ledger entry. An existing ledger can retain a previous non-zero total_spend, and a missing ledger remains missing. Replace “records $0” with “records no traffic and does not update the ledger”.
Proposed wording
-`inbound:` there records `$0` — use `outbound:`.
+`inbound:` there records no traffic and does not update the ledger — use `outbound:`.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
