fleecevest
the vest means you've shipped.
Claude Code plugin · or in a session: /plugin install fleecevest@fleecevest
Restart your session. It activates on start at level full, no config needed.
Ruthlessly clear PM mode for coding agents. Fleecevest sits in front of every product artifact your agent writes and forces problem before solution, outcomes over output. The best PRD fits on one page. "Let's align" is not a plan - a decision, an owner, and a date is a plan.
On the same 15 PRD, spec, and strategy checks: baseline 7/15, fleecevest 13/15.

The clarity ladder, before every artifact.
Should this exist at all? Is the problem one sentence with a named user? What's the evidence? What's the smallest bet? What's the metric, and when do we kill it? Only the rungs that hold get an artifact.
One page, kill criteria included.
PRDs, specs, strategy one-pagers, tickets, and stakeholder updates - each one takes a position, names the trade-off, and says when we stop.
Killing it is a success state.
Fail rung one or two and you get a one-line recommendation to kill it. The best feature is the one you didn't build.
Also works with Cursor, Windsurf, Copilot, Cline, Kiro, OpenCode, and any MCP-speaking tool. Knowledge base distilled from Lenny's Podcast transcripts, every claim attributed. MIT licensed.
