Agent runtime configuration

Fields

name: String

Agent name

description: Option<String>

Agent description

model_id: String

Model ID to use

system_prompt: Option<String>

System prompt

timeout_seconds: u64

Timeout in seconds for the entire agent run

temperature: Option<f64>

Temperature for generation (0.0 to 1.0)

max_tokens: Option<usize>

Maximum tokens to generate

compaction_strategy: CompactionStrategy

Compaction strategy for long conversations

compaction_instruction: Option<String>

Custom instruction passed to the compactor

context_window: usize

Model context window size (used for threshold-based compaction)

workspace_dir: Option<PathBuf>

Working directory for file tools. Defaults to current directory if None.

output_mode: Option<String>

Output mode for agent responses.

When set, the agent extracts structured output from the final response. See OutputMode for available modes.

session_id: Option<String>

Session identity used by tools that gate behavior on liveness (e.g. the issue tool’s start/close ownership checks). When Some, this value is threaded through to crate::tools::ToolContext::session_id. None means the tool receives session_id == None and ownership-gated operations will reject the call (defensive default).

provider_options: Option<ProviderOptions>

Per-provider options for fine-grained control.

When set, these are passed through to oxi_ai::StreamOptions::provider_options so the provider can read provider-specific settings (e.g. Anthropic adaptive thinking, OpenAI reasoning_effort, Google thinkingConfig).

ttsr_engine: Option<Arc<TtsrEngine>>

TTSR engine for stream rule checking. When set, streaming output is checked against registered rules and violations trigger crate::agent_loop::StreamOutcome::RuleInterrupt.

memory: Option<Arc<dyn MemoryBackend>>

Memory backend for memory_* tools.

todo: Option<Arc<dyn TodoStateProvider>>

Todo state provider for the todo tool.

agent_pool: Option<Arc<dyn AgentPoolProvider>>

Agent pool for Hub display and sub-agent matching.

url_resolver: Option<Arc<dyn UrlResolver>>

URL resolver for internal protocol schemes (issue://, pr://, etc.). Threaded through to crate::agent_loop::config::AgentLoopConfig::url_resolver. When None, URL-prefixed paths are treated as regular file paths.

lsp: Option<Arc<dyn LspProvider>>

LSP provider for the lsp tool. Threaded through to crate::agent_loop::config::AgentLoopConfig::lsp. When None, the lsp tool returns an error.

max_tool_result_bytes: Option<usize>

Maximum bytes of a tool result’s text content before truncation (#28 gap 1, surfaced as #32). Threaded through to crate::agent_loop::config::AgentLoopConfig::max_tool_result_bytes.

When set, tool results exceeding this limit are truncated and a "... [truncated: N bytes omitted]" marker is appended, preventing a single large tool output from consuming the context window.

None (default) = no limit. Opt-in.

subagent_runner: Option<Arc<dyn SubagentRunner>>

In-process sub-agent runner (#28 gap 3, surfaced as #32). When set, the subagent tool prefers an in-process isolated run over shelling out. Threaded through to crate::agent_loop::config::AgentLoopConfig::subagent_runner.

subagent_depth: u8

Current sub-agent nesting depth (#28 gap 3, surfaced as #32). Default 0 (top-level). The subagent tool increments this when forking a child config to cap recursion.

snapshot_store: Option<Arc<dyn SnapshotStore>>

Snapshot store for hashline line-anchored edit mode.

When Some, the read tool records file snapshots and emits [path#TAG] headers, and the edit tool validates edits against them. When None (default), hashline anchoring is disabled and the edit tool falls back to plain text replacement.

Implementations

impl AgentConfig

pub fn new(model_id: impl Into<String>) -> Self

Create a new config with the given model ID.

pub fn with_name(self, name: impl Into<String>) -> Self

Set the agent name.

pub fn with_system_prompt(self, prompt: impl Into<String>) -> Self

Set the system prompt.

pub fn with_timeout(self, seconds: u64) -> Self

Set the timeout in seconds for the entire agent run.

pub fn with_compaction_strategy(self, strategy: CompactionStrategy) -> Self

Set the compaction strategy for long conversations.

pub fn with_compaction_instruction(self, instruction: impl Into<String>) -> Self

Set a custom instruction passed to the compactor.

pub fn with_session_id(self, session_id: impl Into<String>) -> Self

Set the session identity threaded into crate::tools::ToolContext::session_id.

Tools that gate behavior on liveness (e.g. an issue tool’s start/close ownership checks) use this to identify the caller. Leaving it None causes those tools to see an empty caller id and reject ownership-gated operations (defensive default).

pub fn with_snapshot_store(self, store: Arc<dyn SnapshotStore>) -> Self

Set the hashline snapshot store — enables line-anchored edit mode in the read/edit tools (emits [path#TAG] headers, validates edits).
