devils-twin
From the author
The strongest possible case AGAINST what you just wrote — argued to win, not to check a box. Use when a document is about to ship and everyone around it already agrees: the twin writes the opposition's best memo (not a critique of yours), so you meet the real counter-argument before your audience does. Produces the opposing memo, the map of which of your claims it defeats/dents/leaves standing, and the pre-emption paragraph worth adding.

- kill-argumentwanshuiyin/Auto-claude-code-research-in-sleepTwo-thread adversarial review: a fresh reviewer constructs the strongest 200-word rejection memo, then a second fresh reviewer defends the paper point-by-point and surfaces still-unresolved critical issues. Use when user says "kill argument", "adversarial review", "hostile review", "rebuttal preparation", "reviewer-2 simulation", or before submitting a theory paper that has already passed standard review rounds.Science★ 17.9K
- decision-memomohitagw15856/pm-claude-skillsWrite a crisp decision memo that drives a clear decision, not a discussion. Use when asked to write a decision memo, a recommendation memo, a one/six-pager for a decision, or to get leadership to decide something. Produces a decision memo — the decision & recommendation up front, the context, options with trade-offs, what you'd need to believe, risks, and the explicit ask with a deadline.Writing★ 1.5K
- the-strong-nomohitagw15856/pm-claude-skillsFind the real reason to NOT do the exciting thing you're about to commit to — the honest case against, before the excitement carries you in. Use when asked talk me out of this, should I really do this, what's the case against, or I'm excited but is this a mistake. Produces the strongest honest argument for not doing it, the excitement biases clouding your judgment, the specific conditions under which this is a bad idea for you, and a clear read on whether the strong no actually wins — protecting you from the plans that feel great and end badly.Planning★ 1.5K
- writing-plansmohitagw15856/pm-claude-skillsWrite an executable work plan BEFORE starting a complex task — decomposed steps with verification points, risks pre-named, and explicit stop conditions — so execution becomes checking boxes instead of improvising. Use when a task will take many steps, when asked to plan before doing, when previous attempts sprawled or stalled, or before delegating work to subagents. Produces a plan document another agent (or future you) could execute without re-deriving the thinking. Pairs with executing-plans.Writing★ 1.5K
- strategy-memomohitagw15856/pm-claude-skillsWrite a strategy memo that commits to a bet and says what you won't do. Use when asked to write a strategy memo, articulate a strategy, make the case for a strategic direction, or align the team on where to focus. Produces a strategy memo — the strategic question, the diagnosis, the bet/approach, why now, explicit non-goals (what we're NOT doing), how we'll know it's working, and the risks.Writing★ 1.5K
- policy-memomohitagw15856/pm-claude-skillsWrite a decision-ready policy memo that frames an issue and recommends an option. Use when asked to write a policy memo, options paper, decision memo for a principal/minister/executive, or brief a decision-maker on a policy choice. Produces a tight memo: the issue, background, options with trade-offs, a clear recommendation, and implementation/risks — written for a busy decision-maker who reads the first paragraph.Science★ 1.5K
