A shared system optimized for product teams. Skills, workflows, and context configured for Claude Code. Ready in minutes.
Used by thousands of product managers
You've copy-pasted PRD prompts into ChatGPT. You've installed Claude. You've watched a few YouTube videos. But you're still writing prompts from scratch. Results miss your context. Nothing scales beyond your own browser tab.
Writing prompts from scratch every time
You re-engineer the same PRD prompt every sprint.
Copy-pasting context all day
Every new chat starts with re-explaining your product, your personas, your goals. Your context lives in scattered prompts, not a system.
Knowledge stuck in your browser, not your team
Your best prompts live in browser tabs nobody else can see.
Organized by how you actually work — not a feature dump.
01 · Research
Map JTBDs, extract patterns, build an opportunity tree.
7–10 hours manual → 15 minutes with mySecond.
02 · Decide
Simulate CTO, UX, Sales, and Devil's Advocate perspectives.
No PM peers to gut-check? You don't need them.
03 · Build
Full spec with acceptance criteria, risks, test plan.
Specs consume disproportionate PM time. 85% done in minutes.
04 · Launch
Strategy, launch checklist, pricing analysis, messaging matrix.
Ad-hoc launches → repeatable, framework-backed every time.
PRD generator, roadmap builder, weekly metrics, discovery prep — proven workflows, not random prompts. Each skill reads your context automatically.
Discovery prep → PRD → launch plan. Workflows orchestrate the whole sequence so you handle the judgment calls, not the orchestration.
The same files your skills read in Claude Code — editable in mySecond. Update once. Every skill, every PM, gets the latest.
Adoption dashboard, context health, and context approvals — all in mySecond. Run the system from the browser, not the terminal.
Install mySecond in Claude Code — context loaded in minutes.
Run skills and workflows on the PRDs and strategy docs already on your plate.
Edit context, review proposed changes, and watch adoption — in your browser.
Roll out one shared system across every PM, with approvals and cost visibility.
