Agently Agent Extensions

Use this skill when the problem is agent-side extension rather than prompt shape, output contract, or workflow control.

Native-First Rules

• prefer built-in extension surfaces before handwritten wrappers
• keep extension choice explicit: tools, MCP, FastAPIHelper, auto_func, KeyWaiter, or agently-devtools
• treat agently-devtools as an optional companion package installed from PyPI, not as a required source checkout
• keep observation or evaluation bridge wiring in the app layer through Agently.event_center
• combine with agently-model-response or agently-triggerflow only when the scenario needs those layers
• prefer built-in Browse support with Playwright or PyAutoGUI before writing browser or desktop-driving wrappers from scratch

Anti-Patterns

• do not build a parallel tool dispatcher before checking native tool and MCP support
• do not create a custom waiter or auto-function shim first
• do not ask users to clone or editable-install DevTools when pip install agently-devtools is the supported public path
• do not build a custom runtime upload bridge before checking ObservationBridge
