mbackschat Skill A12 Dmtool Bug Report 2Produce a well-isolated bug-and-findings report for the dmtool CLI (a12-dmkits / A12 kernel) and save it to a folder the user picks. Use when a user hits an error, crash, internal error, or unexpected behaviour in dmtool, when they want to capture findings / DX friction / improvement notes, or when they ask to write or file a bug report against dmtool. Covers reading the result envelope (telling an internal tool error apart from a rejected input), shrinking to a minimal repro, an affected-vs-unaffected table, classifying genuine defects vs. your own input mistakes, a verbatim replay log, and a self-audit — then writing the report to a folder the user can upload or send however they like.

b1rdmania Bundle Plain English 2Tighten prose by stripping AI tics and applying Orwell/Gowers plain-English rules. Use when the user asks to rewrite, tighten, simplify, or detox writing — phrases like "plain English", "make this clearer", "cut the AI voice", "fix the writing", "rewrite plainly", "tighten this", "detox this". Also run as a self-audit pass before delivering long-form prose (essays, blog posts, articles, reports) so the output isn't recognisably AI-generated. Three modes: audit (flag + suggest), rewrite (deliver cleaned prose), edit (fix a named file in place). Technical documentation routes to the simple-english skill instead.

lirantal Bundle Statusline Creator 2Builds a Claude Code statusline from scratch or extends an existing one. A statusline is a live status bar that runs a shell script after every Claude response and displays data — security scans, git status, API quotas, build state — directly in the session. Use this skill when the user says "create a statusline", "make a statusline for X", "add X to my statusline", "show Y in the status bar", "build a statusline plugin", or "I want live data in my Claude session". Trigger even if the user just describes wanting live feedback during a Claude session without naming "statusline" explicitly. The skill drives from idea to a working, installed, tested statusline without requiring the user to direct every step.

luka-zivkovic Bundle Review Contract Gaps 5Produce a read-only semantic contract-gap pass for an exact implemented change, optionally subtracting a frozen pull-request review. Use only when explicitly asked for an implementation-aware second pass or standalone deep contract audit, especially for persisted values, shared configuration, public contracts, migrations, state transitions, or multiple producers and consumers. Discover against code before reading any supplied review, then return only source-verified omissions.
