Triage a Delphi FMX Android bug/crash from the PC over adb: capture logcat, pull the app's LightCore.ExceptionLogger log via run-as, classify the failure (SIGUSR1 IDE noise / Pascal exception / Java exception / native tombstone / deployment), symbolicate stripped-.so addresses against the linker .map (Tools\MapLookup.ps1), then root-cause and fix (build via light-compiler, never release). Use when the user says "/light-bug-Android", "the Android app crashes", "the app silently disappears on the phone", "triage this logcat", "exception class 10", or an FMX bug shows only on Android.
Diagnose and fix a Delphi bug end-to-end, however it arrived: a Thunderbird crash report (.mad), a pasted exception/stack trace, or a symptom described in plain words. Routes internally — a .mad or 'crash report' goes to the light-bug-MadShi pipeline, an Android-only symptom hands off to /light-bug-Android, everything else runs here: intake, reproduce (a failing DUnitX test preferred), localize, a MANDATORY derailment check before any fix, fix, then verify and compile (never releases). Use whenever the user reports a bug, crash, or unexpected behavior in a Delphi project — says "/light-bug", "/light-bug bionix", "I have a crash in program X", "the app does Y instead of Z", "this doesn't work", pastes an exception or stack trace, forwards a bug-report email, or describes an app crashing/hanging/misbehaving — even without typing a command.
Fix Delphi vocabulary and writing-clarity issues in Markdown docs — non-Delphi term swaps + bounded clarity rewrites. Say "check vocab", "fix vocabulary", "delphi terms", "clean up the md", or after writing/editing *.md in a Delphi project.
Audit Claude Code config files (settings.json, settings.local.json, .mcp.json) across the computer for unsafe or malicious content — hooks that run shell commands, credential/proxy env vars, arbitrary MCP servers, permission-bypass modes, over-broad allow rules. Classifies each finding DANGEROUS / SUSPICIOUS / SAFE. Read-only. Use when the user invokes `/light-security-ClaudeSettingsAudit`, says "check my settings.local.json for malware", "are my Claude permission files safe", "scan my Claude config", or "audit settings.json across the computer".
Summarize a YouTube transcript .txt file — cleans it first, then produces a structured summary (with a Delphi 13 / LightSaber adaptation section when the talk is about programming). Launches the light-web-YoutubeSummarizer agent. Use when the user invokes `/light-web-YoutubeSummarizer`, says "summarize this transcript", "what can I learn from this video for my Delphi work", or points at a file in c:\AI\Claude Code\Transcript\.
Pause mid-task and verify your own conclusions before continuing: classify every load-bearing conclusion VERIFIED / INFERRED / ASSUMED with evidence, actively attack the unverified ones, and find the earliest wrong turn if one exists. Not Delphi-specific — usable in any long or drifting task, in any language. Use when the user says "derailment check", "are you on track", "checkpoint yourself", "pause and check your conclusions", "/light-task-DerailmentCheck", or after any long autonomous stretch. ALSO fire this on yourself, unprompted, whenever: the user says "nope"/"no"/"wrong"/"stop" or otherwise corrects you; a fix didn't change the symptom; two fix attempts on the same problem both failed; you're editing a file your own analysis never mentioned; you're explaining away contradicting evidence instead of checking it; or you're about to act without ever having reproduced the problem.
Audit Delphi source for Win64 truncation bugs — pointer-width API results (DWORD_PTR/LRESULT/handles) stored in 32-bit variables (Integer/Cardinal/DWORD/UInt), and 32-bit casts of pointers passed to the API. Say "audit for Win64 bugs", "check 64-bit safety", "search for SysIL-class bugs".
Alias for /light-bug-MadShi with the BioniX product preselected. Diagnose and fix a BioniX Wallpaper crash report from Thunderbird, then build (never release). Use when the user says "/light-bug-BioniX", "new BioniX bug report", "check the latest BioniX crash", or similar.
