# Tool Architecture
**Keep tool-specific logic out of the main agent codebase.** The main agent provides generic infrastructure; tools are self-contained units that declare requirements through `<name>.capabilities.json` sidecar files (in dev mode: `tools-src/<name>/<name>-tool.capabilities.json`).
Tools can be WASM (sandboxed, credential-injected, single binary) or MCP servers (ecosystem, any language, no sandbox). Both are first-class via `ironclaw tool install`.
See `src/tools/README.md` for full architecture, adding new tools, auth JSON examples, and WASM vs MCP decision guide.
## Tool Implementation Pattern
```rust
#[async_trait]
impl Tool for MyTool {
fn name(&self) -> &str { "my_tool" }
fn description(&self) -> &str { "Does something useful" }
fn parameters_schema(&self) -> serde_json::Value {
serde_json::json!({
"type": "object",
"properties": {
"param": { "type": "string", "description": "A parameter" }
},
"required": ["param"]
})
}
async fn execute(&self, params: serde_json::Value, ctx: &JobContext)
-> Result<ToolOutput, ToolError>
{
let start = std::time::Instant::now();
// ... do work ...
Ok(ToolOutput::text("result", start.elapsed()))
}
fn requires_sanitization(&self) -> bool { true } // External data
}
```
