Shannon works best with Claude models. Anthropic API keys are recommended for most users, and Shannon also supports AWS Bedrock and custom Anthropic-compatible endpoints.
|
|
|
|
## Anthropic
|
|
|
|
Run the setup wizard:
|
|
|
|
```bash
|
|
npx @keygraph/shannon setup
|
|
```
|
|
|
|
Or export an API key directly:
|
|
|
|
```bash
|
|
export ANTHROPIC_API_KEY=your-api-key
|
|
```
|
|
|
|
Source-build mode can use a `.env` file:
|
|
|
|
```bash
|
|
ANTHROPIC_API_KEY=your-api-key
|
|
```
|
|
|
|
Each tier can be pointed at any Claude model via `ANTHROPIC_SMALL_MODEL` / `ANTHROPIC_MEDIUM_MODEL` / `ANTHROPIC_LARGE_MODEL` (or the setup wizard). If you set a tier to `claude-fable-5`, note that Fable's safety classifiers route cybersecurity tasks to Opus 4.8, so those phases run on Opus 4.8 regardless.
|
|
|
|
## AWS Bedrock
|
|
|
|
Run `npx @keygraph/shannon setup` and select **AWS Bedrock**. The wizard prompts for region, bearer token, and model IDs.
|
|
|
|
Or export environment variables directly:
|
|
|
|
```bash
|
|
export CLAUDE_CODE_USE_BEDROCK=1
|
|
export AWS_REGION=us-east-1
|
|
export AWS_BEARER_TOKEN_BEDROCK=your-bearer-token
|
|
export ANTHROPIC_SMALL_MODEL=us.anthropic.claude-haiku-4-5-20251001-v1:0
|
|
export ANTHROPIC_MEDIUM_MODEL=us.anthropic.claude-sonnet-4-6
|
|
export ANTHROPIC_LARGE_MODEL=us.anthropic.claude-opus-4-8
|
|
```
|
|
|
|
Source-build `.env` equivalent:
|
|
|
|
```bash
|
|
CLAUDE_CODE_USE_BEDROCK=1
|
|
AWS_REGION=us-east-1
|
|
AWS_BEARER_TOKEN_BEDROCK=your-bearer-token
|
|
ANTHROPIC_SMALL_MODEL=us.anthropic.claude-haiku-4-5-20251001-v1:0
|
|
ANTHROPIC_MEDIUM_MODEL=us.anthropic.claude-sonnet-4-6
|
|
ANTHROPIC_LARGE_MODEL=us.anthropic.claude-opus-4-8
|
|
```
|
|
|
|
Shannon uses three model tiers:
|
|
|
|
- **small** for summarization
|
|
- **medium** for security analysis
|
|
- **large** for deep reasoning
|
|
|
|
Set `ANTHROPIC_SMALL_MODEL`, `ANTHROPIC_MEDIUM_MODEL`, and `ANTHROPIC_LARGE_MODEL` to Bedrock model IDs available in your region.
|
|
|
|
## Custom Base URL
|
|
|
|
Shannon supports pointing the SDK at an Anthropic-compatible endpoint with `ANTHROPIC_BASE_URL`. For proxy-based routing, use an LLM proxy such as LiteLLM configured to expose an Anthropic-compatible endpoint.
|
|
|
|
> [!IMPORTANT]
|
|
> Only Claude models are officially supported. Shannon's evaluations, internal testing, and agent harness are optimized for Claude. Smaller or alternative models, including non-Claude models routed through a proxy, may not reliably follow Shannon's instructions or tool-use constraints. Use them at your own risk.
|
|
|
|
The experimental `claude-code-router` integration has been removed. If you previously relied on it, migrate to an Anthropic-compatible proxy such as LiteLLM.
|
|
|
|
Run `npx @keygraph/shannon setup` and select **Custom Base URL**, or export variables directly:
|
|
|
|
```bash
|
|
export ANTHROPIC_BASE_URL=https://your-proxy.example.com
|
|
export ANTHROPIC_AUTH_TOKEN=your-auth-token
|
|
export ANTHROPIC_SMALL_MODEL=claude-haiku-4-5-20251001
|
|
export ANTHROPIC_MEDIUM_MODEL=claude-sonnet-4-6
|
|
export ANTHROPIC_LARGE_MODEL=claude-opus-4-8
|
|
```
|
|
|
|
Source-build `.env` equivalent:
|
|
|
|
```bash
|
|
ANTHROPIC_BASE_URL=https://your-proxy.example.com
|
|
ANTHROPIC_AUTH_TOKEN=your-auth-token
|
|
ANTHROPIC_SMALL_MODEL=claude-haiku-4-5-20251001
|
|
ANTHROPIC_MEDIUM_MODEL=claude-sonnet-4-6
|
|
ANTHROPIC_LARGE_MODEL=claude-opus-4-8
|
|
```
