Struct Anthropic Cache Plugin

Generated from cargo doc --no-deps -p nemo-relay -p nemo-relay-adaptive -p nemo-relay-ffi.

Anthropic cache plugin for the Adaptive Cache Governor (ACG) system.

Translates ACG stability classifications into Anthropic-specific cache_control breakpoints on content blocks. Implements the ProviderPlugin trait with:

  • Breakpoint budget allocation: Up to 4 breakpoints per request.
  • Token minimum enforcement: Per-model from CapabilityRegistry.
  • TTL mapping: RetentionTier to Anthropic TTL (5m default or 1h extended).
  • Tool schema canonicalization: RFC 8785 via [canonicalize_value].
  • System string-to-array conversion: Handles both string and array-of-blocks format.

Threat mitigations

  • T-08-01: Only injects cache_control annotations with fixed structure {"type": "ephemeral"}.
  • T-08-02: scope_label is logged in detail but does NOT change cache visibility.
  • T-08-03: All JSON access uses Option-returning methods; errors propagate via Result.
  • T-08-05: TTL is hardcoded to exactly 2 behaviors (omit or "1h").

Structs

  • AnthropicCachePlugin: Anthropic-specific provider plugin for cache_control breakpoint injection.
