Critical-thinking brainstorming partner that acts as a requirements analyst. Use when users present ideas, feature requests, or problems they want to solve. Triggers include "I want to build", "help me validate", "users need", "I'm thinking of creating", or any request involving problem/solution validation. This skill aggressively challenges assumptions, questions perceived problems, demands evidence, and ensures solutions address genuine needs before exploring implementation.
Generate, refine, research, and validate startup ideas through an interactive founder-specific idea machine. Use when Codex needs to ask a few focused questions, search current public web signals, rapidly brainstorm startup or SaaS ideas, learn from love/maybe/no reactions, produce additional idea rounds, compare finalists, investigate competitors and existing workarounds, select a promising opportunity, or create an evidence-linked Markdown startup-idea report.
Complete startup launch guidance from idea validation to market entry. Use when planning a new business, validating product ideas, or preparing for launch.
Generate comprehensive Product Requirements Documents (PRD) from idea validation files. Use when users ask to "create a PRD", "generate product requirements", "write a PRD", or want to turn validated ideas into actionable product specs. Works with idea.md and validate.md files from the idea-validator skill.
Generate and validate startup ideas through market research, skill-market fit, and iterative refinement.
Guided discovery of a product idea by mining what the founder already knows or already does — covers source selection (business vs. expertise), context capture, pattern synthesis, candidate scorecard, and writes `docs/product-idea.md`. Use when the founder says "generate an idea", "help me find an idea", "what should I build", "product idea from my business", "product idea from my expertise", or otherwise needs to discover a product concept worth building.
Use when you have a rough idea and want to refine it into a well-formed proposal before submitting to Nexus. Must check directive first - all ideas must align with current organizational focus.
Use when asked to brainstorm, evaluate whether an idea is worth building, run office hours, or think through a new product idea or design direction before any code is written.
The anti-yes-man. Interrogate any idea, plan, price change, or pitch like an investor until it survives or dies, one pointed question at a time, each with a recommended answer. Run when the user says "is this a good idea", "poke holes in this", "run this through the gauntlet", "stress-test this", "would you invest in this", "play devil's advocate", or pitches something and asks what you think. Flattery is never the answer; this skill is.
ProductBurst platform help — product launch and discovery platform for startups with daily and weekly rankings. Covers product submission (launch in under 5 minutes, no gatekeepers), daily/weekly leaderboard rankings (not single-day like Product Hunt), community upvoting, Top of Day/Week badges (shareable SVGs), featured homepage placement (one-time fee), do-follow backlinks (DR46), comment threads, idea validation without a full build, and marketplace. Use when your product isn't getting noticed on launch day, your ProductBurst listing isn't ranking, you need visibility without Product Hunt's gatekeeping, or you want a do-follow backlink from a DR46 directory. Do NOT use for general launch strategy across multiple directories (use /sales-launch-directory), email marketing (use /sales-email-marketing), or audience growth (use /sales-audience-growth).
Grill the user relentlessly about any idea, plan, or design, a round of unblocked decisions at a time, each with a recommended answer, until you both share the same picture. Use when the user wants to stress-test or pressure-test an idea, says "grill me", "grill this plan", "poke holes in this", "interrogate my design", or otherwise asks to interrogate a concept before committing to it, whether a rough idea, a plan file, an architecture, or a PR.
Help users conduct high-impact customer interviews that move beyond surface-level feature requests to identify root emotional frustrations and specific causal triggers.
