Auto-Compaction (Azure Anthropic)

examples/compaction-azure-anthropic.rs demonstrates enable_auto_compaction end to end on Azure-hosted Anthropic endpoints. Azure Anthropic preserves the Messages wire format, so the compaction beta header (compact-2026-01-12) and context_management edit work exactly like the direct Anthropic API — appam adds both automatically when compaction is enabled.

Requires a compaction-capable Claude deployment (Sonnet 4.6+, Opus 4.6+, or the Claude 5 family).

Run

export AZURE_ANTHROPIC_BASE_URL="https://my-resource.services.ai.azure.com/anthropic"
export AZURE_ANTHROPIC_API_KEY="..."        # or AZURE_API_KEY
export AZURE_ANTHROPIC_MODEL="claude-opus-4-6"   # deployment name, optional
cargo run --example compaction-azure-anthropic

What this example actually configures

• LlmProvider::AzureAnthropic with x-api-key authentication
• enable_auto_compaction(50_000) — the Anthropic minimum trigger
• One local tool: fetch_archive (~16K tokens per volume)
• An on_compaction stream hook that prints the summary preview
• A post-run report over session.messages and session.usage

Key builder setup

let agent = AgentBuilder::new("compaction-demo-azure-anthropic")
    .provider(LlmProvider::AzureAnthropic {
        base_url: base_url.clone(),
        auth_method: appam::llm::anthropic::AzureAnthropicAuthMethod::XApiKey,
    })
    .model(&model)
    .system_prompt("You are an expedition archivist. ...")
    .enable_auto_compaction(50_000)
    .with_tool(Arc::new(fetch_archive()))
    .max_tokens(4096)
    .build()?;
