The jump to managing is a role change, not a promotion for doing more of the same — and most first-time managers stumble by either changing everything on day one or staying an individual contributor with a title. This gives a phased first-90-days plan: earn trust and learn first, then set direction, then adjust — plus how to handle the 1:1s, delegation, and hard conversations that define the job.
New Manager First 90 Days is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/new-manager-first-90-days/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when asked to help me as a new manager, I just became a manager, first-time manager advice, or my first 90 days managing a team. Produces a phased 90-day plan (listen and learn, then set direction, then adjust), how to run your first 1:1s, the mindset shift from doer to enabler, common traps to avoid (doing it all yourself, changing too fast, avoiding hard conversations), and early wins that build credibility.
