Fields

backend: Arc<dyn Backend>

Backend for filesystem operations.

system_prompt: Option<String>

Optional system prompt prepended to all model calls.

tools: Vec<Arc<dyn Tool>>

Additional tools beyond the built-in filesystem tools.

middleware: Vec<Arc<dyn AgentMiddleware>>

Additional middleware beyond the built-in stack.

checkpointer: Option<Arc<dyn Checkpointer>>

Optional checkpointer for graph state persistence.

store: Option<Arc<dyn Store>>

Optional store for runtime tool injection.

max_input_tokens: usize

Maximum input tokens before summarization (default 128,000).

summarization_threshold: f64

Fraction of max_input_tokens that triggers summarization (default 0.85).

eviction_threshold: usize

Token count above which tool results are evicted to files (default 20,000).

max_subagent_depth: usize

Maximum nested subagent depth (default 3).

skills_dir: Option<String>

Skills directory path in the backend (default “.skills”).

memory_file: Option<String>

Memory file path in the backend (default “AGENTS.md”).

subagents: Vec<SubAgentDef>

Custom subagent definitions for the task tool.

enable_subagents: bool

Enable subagent spawning via task tool (default true).

enable_filesystem: bool

Enable filesystem tools (default true).

enable_skills: bool

Enable skills middleware (default true).

enable_memory: bool

Enable memory middleware (default true).

Implementations

impl DeepAgentOptions

pub fn new(backend: Arc<dyn Backend>) -> Self

Create options with the given backend and sensible defaults.
