codex-imagegen
Generate or edit raster images (photos, illustrations, mockups, logos, product shots, game/UI assets, textures, infographics) using Codex's built-in image_gen tool — driven headlessly through `codex exec`. Billed via the user's ChatGPT/Codex login, so it needs NO OpenAI API key. Use whenever the user wants to create a brand-new image from a text prompt, edit an existing local image (background swap, lighting/weather change, object add/remove, restyle), or produce several image variants. Trigger on "generate an image", "make a picture/illustration/logo/mockup of X", "create a hero image", "edit this image", "change the background of X", "turn this photo into Y", "imagegen", "use codex to make an image". Do NOT use for vector/SVG icon systems, diagrams better built in code/HTML/CSS, or when the user explicitly wants the OpenAI Image API directly (that's the gpt-image CLI path).

learn-craft
Generate a deep, book-grounded skill for any subject the user wants to master. Researches the canonical books on the topic, downloads them as PDFs (using the bundled `scripts/libgen.py` downloader), reads them in parallel via subagents, then synthesizes the books across each other into a concept-organized knowledge base — not a shelf of book summaries. Output is a tight `SKILL.md` plus per-concept `frameworks/` files (the working knowledge base, organized by idea) plus per-book `references/` deep-dives (the citation layer). Trigger whenever the user says they want to "learn X", "master X", "build a skill for X", "study X", "get smarter at X", "make me a skill on X", "I want to be good at X", "teach me X", "create a coach for X", or asks for help internalizing the canonical thinking on a craft, discipline, methodology, or domain. Don't trigger for "make a skill that does Y" (workflow automation — use /skill-creator). Trigger for "make a skill that helps me think like Y" (knowledge synthesis — that's this skill).

ultimate-sales
Master sales coaching skill synthesizing six foundational books — SPIN Selling, Fanatical Prospecting, Gap Selling, The Challenger Sale, Never Split the Difference, and How to Win Friends & Influence People. Use this skill any time the user is drafting outbound emails, cold DMs, follow-up messages, or any sales/prospecting outreach; preparing for or reviewing sales calls, discovery calls, demos, or QBRs; thinking through pricing, objections, negotiations, or closing strategy; planning ICP, messaging, channels, sequencing, or pipeline strategy; coaching reps or being coached; reviewing or rewriting their own sales messaging; even if they don't say "sales," "selling," or name a framework. Trigger on phrases like "cold email", "outreach", "DM", "follow-up", "prospect", "lead", "stalled deal", "objection", "discovery call", "demo", "proposal", "negotiate price", "they ghosted me", "how do I get a meeting", "I'm pitching", "what should I say to", "deal review", "champion", "buying committee", "ICP", "sales pitch", "founder-led sales". Always diagnose the stage of the sales journey first, then apply the right frameworks from the right books — most sales failures come from using a small-sale tactic in a big-sale context, pitching before diagnosing, or arguing instead of asking.

growth-hacker
Diagnose the real growth bottleneck and prescribe the next move, using the unified frameworks from Ryan Holiday's Growth Hacker Marketing, Sean Ellis & Morgan Brown's Hacking Growth, and Weinberg & Mares' Traction. Use whenever the user is thinking about how to grow a startup, increase signups, fix a leaky funnel, pick a marketing channel, run growth experiments, find product-market fit, increase activation, retain users, build virality, or hit a revenue milestone. Also trigger on "stuck at $X MRR", "should I run ads on Y", "my conversion is 0%", "how do I get my first 100 users", "marketing strategy", "go-to-market", "ICE score", "Bullseye", "aha moment", "PMF", "viral loop", "referral program", "retention curve", or any situation where a founder is choosing between growth tactics. Refuses to recommend a tactic before diagnosing the stage — founders picking the channel they're comfortable with, not the one their stage needs, is the
