Bug Description

Version: 0.10.0

Problem: When using Bedrock with an inference profile ID like global.anthropic.claude-sonnet-4-6, the normalize_model_name() function in agent/anthropic_adapter.py converts all dots to hyphens, producing the invalid ID global-anthropic-claude-sonnet-4-6. This causes HTTP 400: The provided model identifier is invalid.

The dots in Bedrock inference profile IDs (global., us., eu., ap., jp.) are namespace separators, not version separators, and must be preserved.

Steps to reproduce:

Set model.default: global.anthropic.claude-sonnet-4-6 and model.provider: bedrock in config.yaml Run hermes chat Get HTTP 400: The provided model identifier is invalid.

Root cause: normalize_model_name() unconditionally replaces . → - for Anthropic API compatibility (OpenRouter uses dots in versions, Anthropic uses hyphens). But Bedrock inference profile IDs use dots as namespace separators and are passed to the AnthropicBedrock SDK, which requires

Steps to Reproduce

1.Set model.default: global.anthropic.claude-3-5-sonnet-20240620-v1:0 (or any Bedrock ID with dots) in config.yaml. 2.Set model.provider: bedrock. 3.Run hermes chat.

Expected Behavior

The dots in Bedrock inference profile IDs (which act as namespace separators like global., us., etc.) should be preserved so the SDK can correctly identify the routing profile.

Actual Behavior

Affected Component

Configuration (config.yaml, .env, hermes setup)

Messaging Platform (if gateway-related)

Discord

Root Cause Analysis (optional)

In agent/anthropic_adapter.py, the normalize_model_name() function unconditionally replaces . with - to ensure compatibility between OpenRouter (uses dots) and Anthropic (uses hyphens).

However, Bedrock's regional/global prefixes use dots as essential namespace separators, not versioning separators, and must remain intact.

Proposed Fix (optional)

anthropic_adapter.py: def normalize_model_name(model: str, preserve_dots: bool = False) -> str: """Normalize a model name for the Anthropic API.

- Strips 'anthropic/' prefix (OpenRouter format, case-insensitive)
- Converts dots to hyphens in version numbers (OpenRouter uses dots,
  Anthropic uses hyphens: claude-opus-4.6 → claude-opus-4-6), unless
  preserve_dots is True (e.g. for Alibaba/DashScope: qwen3.5-plus).
- Preserves Bedrock inference profile IDs (global., us., eu., ap., jp.)
  which use dots as namespace separators, not version separators.
