madappgang Bundle

Verify, screenshot, AND drive a native macOS app on the same machine the user is actively working on, WITHOUT stealing their mouse, keyboard, or window focus. Use this whenever you need to screenshot, inspect, click through, or confirm the behavior of a running Mac app (Swift/SwiftUI, Electron, AppKit, a dev build, a cloned app) and the user is present at the machine — even if they just say "check that it works", "screenshot the app", "verify the UI", "does the picker show X", "click through the flow", or "test my app". Especially use it the moment driving the GUI with computer-use would yank focus away from the user. Covers focus-free window capture (screencapture -l), focus-free clicking and typing via the Accessibility API (AXPress / set value), read-only window/process/file inspection, and human-handoff only when AX genuinely can't reach a control.

juscribe Bundle

How to run a retrospective on an iteration and hand it over as a self-contained HTML report with charts, then record it back on the board. Covers what to gather (the first-hand accounts first — the ticket comments that hold most of them — then the tickets, their activity and the board's timezone), the sections a retrospective owes and the ones it must stop writing, when in the day work actually happened, production health and standing technical debt, drawing conclusions rather than counting metrics, hand-authored inline-SVG charts that need no library and no network, verifying derived numbers before you publish, sending the report's own HTML to the board so the iteration's details pane can show it, and writing the record back as an iteration comment. Auto-invoke on "retrospective", "retro", "sprint review", "review the iteration", or any request to review or summarize what an iteration delivered.
