Feature flags

The umbrella crate agentkit re-exports subcrates behind feature flags.

Default flags

• core — agentkit-core
• capabilities — agentkit-capabilities
• tools — agentkit-tools-core
• task-manager — agentkit-task-manager
• loop — agentkit-loop
• reporting — agentkit-reporting

Optional flags

• compaction — agentkit-compaction
• context — agentkit-context
• mcp — agentkit-mcp
• adapter-completions — agentkit-adapter-completions
• provider-anthropic — agentkit-provider-anthropic
• provider-cerebras — agentkit-provider-cerebras
• provider-groq — agentkit-provider-groq
• provider-mistral — agentkit-provider-mistral
• provider-ollama — agentkit-provider-ollama
• provider-openai — agentkit-provider-openai
• provider-openrouter — agentkit-provider-openrouter
• provider-vllm — agentkit-provider-vllm
• tool-fs — agentkit-tool-fs
• tool-shell — agentkit-tool-shell
• tool-skills — agentkit-tool-skills
• tool-compose — agentkit-tool-compose

Typical combinations

Minimal orchestration:

agentkit = { version = "0.9.0", features = ["core", "capabilities", "tools", "loop"] }

Coding agent:

agentkit = { version = "0.9.0", features = [
    "core", "capabilities", "context", "tools",
    "loop", "tool-fs", "tool-shell", "reporting",
] }

MCP-enabled agent:

agentkit = { version = "0.9.0", features = [
    "core", "capabilities", "context", "tools",
    "loop", "tool-fs", "tool-shell", "reporting", "mcp",
] }

OpenRouter-backed example host (streaming, prompt caching):

agentkit = { version = "0.9.0", features = [
    "core", "capabilities", "tools", "loop",
    "reporting", "provider-openrouter",
] }

OpenAI-compatible provider host (streaming):

agentkit = { version = "0.9.0", features = [
    "core", "capabilities", "tools", "loop",
    "reporting", "provider-groq",
] }

Swap provider-groq for provider-mistral, provider-vllm, provider-ollama, or provider-openai as needed.

Anthropic Messages API host (streaming, extended thinking, server tools):

agentkit = { version = "0.9.0", features = [
    "core", "capabilities", "tools", "loop",
    "reporting", "provider-anthropic",
] }

Cerebras Inference host (streaming, reasoning, rate-limit snapshot):

agentkit = { version = "0.9.0", features = [
    "core", "capabilities", "tools", "loop",
    "reporting", "provider-cerebras",
] }

The agentkit-provider-cerebras crate itself carries granular Cargo features for preview surfaces: compression (msgpack + gzip request bodies), predicted-outputs, service-tiers, batch (Files + Batch API), and an experimental umbrella that pulls in all three preview flags. Enable them on the provider crate directly when you need them — the umbrella provider-cerebras flag wires in the default build.
