Guidelines on creating issues on GitHub
Run a premortem on any plan, launch, product, hire, strategy, or decision. Assumes it already failed 6 months from now and works backward to find every reason why. Produces a revised plan with blind spots exposed. MANDATORY TRIGGERS: 'premortem this', 'premortem my', 'run a premortem', 'what could kill this', 'future-proof this', 'stress test this plan', 'what am i missing here', 'find the blind spots'. STRONG TRIGGERS: 'what could go wrong', 'am i missing anything', 'poke holes in this', 'where will this break', 'devil's advocate this'. Do NOT trigger on simple feedback requests, or factual questions. DO trigger when someone has a plan or commitment where the cost of being wrong is high.
Schedule a prompt to fire back at yourself at a future time or on a recurring cron pattern. Use when the user says "remind me", "every N minutes/hours/days", "at HH:MM tomorrow", "check X periodically", or otherwise asks for any time-based action. Triggered by the `schedule` tool plus the `/schedule` command for listing and deletion.
Interview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree. Use when user wants to stress-test a plan, get roasted on their design, or mentions "brainstorm".

tsdown is a next-generation TypeScript library bundler built on Rolldown and Oxc. It provides blazing-fast builds, automatic .d.ts generation, and seamless migration from tsup. Supports Rolldown/Rollup/Unplugin plugins and features smart dependency handling.
This documentation is based on tsdown v0.20.1.
