Struct ToolRegistry 

pub struct ToolRegistry { /* private fields */ }

Registry of dispatchable tools. Single source of truth for what the model sees AND what handles a call when the model issues it. Built once at startup; read-only after that.

Implementations

impl ToolRegistry

pub fn new() -> Self

pub fn register(&mut self, tool: Arc<dyn ToolExecutor>)

pub fn get(&self, name: &str) -> Option<Arc<dyn ToolExecutor>>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn names(&self) -> impl Iterator<Item = &'static str> + '_

pub fn describe_all(&self) -> Vec<ToolDefinition>

Emit every user-facing tool’s schema, for inclusion in an outgoing ChatRequest.tools. Effect runner calls this before dispatching Cmd::CallModel so the model always sees the same list the runner can dispatch. Internal routers (the MCP proxy) are filtered out.

impl ToolRegistry

pub fn build( _config: &Config, mode: TuiMode, providers: Arc<ProviderFactory>, ) -> Arc<Self>

Config-aware factory. Always registers filesystem + exec + the MCP proxy + the subagent tool. Conditionally registers:

• web_search + web_fetch iff OLLAMA_API_KEY resolves (via utils::resolve_api_key). Without a key, the tools would error on every call — so we don’t advertise them at all.
• All seven computer-use tools iff mode == Interactive AND computer_use::probe() returns a usable backend.

providers is the shared ProviderFactory that the effect runner also holds; the SubagentSpawner needs it so child reducer loops hit the same provider cache.

Returns Arc<Self> so the effect runner can share a handle across turns without cloning the underlying HashMap.

Trait Implementations

impl Default for ToolRegistry

fn default() -> Self

Returns the “default value” for a type.
