 - this lines up with `pyproject.toml`, where ACP support is optional and gated behind the `acp` extra (`agent-client-protocol>=0.9.0,<1.0`)

 ## Performance Characteristics
 
-### 1. Prompt caching is a first-class optimization
+### 1. prompt caching is a first-class optimization
 Hermes preserves long-lived agent instances and supports provider-specific prompt caching for compatible providers.
 That is essential because repeated system prompts and tool schemas are expensive.
 
-### 2. Context compression is built into the runtime
+### 2. context compression is built into the runtime
 Compression is not a manual rescue path only.
 Hermes estimates token budgets, prunes old tool noise, and can summarize prior context when needed.
 
-### 3. Parallel tool execution exists, but selectively
+### 3. parallel tool execution exists, but selectively
 The runtime can batch safe tool calls in parallel rather than serializing every read-only action.
 This improves latency without giving up all control over side effects.
