Pick an open bug report, investigate the codebase, and create an implementation plan to fix it. Use when user asks to fix a bug, work on a bug, tackle a bug, or pick up a bug.
Pick an open bug from DevPlans/Bugs/, investigate the codebase, and enter plan mode with a concrete fix plan.
Use Glob to find all OPEN-*.md files in G:\Sandy\DevPlans\Bugs\ (top-level only, not the Backlog/ subfolder). Backlog bugs are excluded — they are parked for later.
If arguments were provided (e.g. /fix-bug PlayerFalls), try to fuzzy-match to one of the open bugs. If there is exactly one match, use it. Otherwise, or if no arguments were given, use AskUserQuestion to present the list of open bugs and let the user choose which one to work on. Show the bug filename (without OPEN- prefix and .md suffix) as the option labels.
Read the full contents of the selected bug report file. Extract:
Launch an Explore subagent using the Task tool to deeply investigate the bug:
