decide
Log a decision. Drafts a complete decision file from the existing evidence trail and surfaces it for PM sign-off.
Generate or refresh hypotheses for a feature. Works **pre-ship** (proactive, organized by the 5 risk areas) or **post-ship** (data-derived from analytics / interviews / churn — "why is retention dropping?"). Same schema either way; the `Origin` field distinguishes them.

A feature slug (`/hypothesize weekly-digest`), a problem statement (`/hypothesize "mid-market onboarding drop-off"`), or an existing hypothesis file to refresh (`/hypothesize hypotheses/weekly-digest.md`).
If the feature has no existing file yet, the command creates one. If it does, the command refreshes — opening new candidate hypotheses where evidence has accumulated, and surfacing any existing ones whose evidence has gone stale.
**Hard constraints:**
A second brain for product managers. Plain markdown files in a folder on your laptop. Claude reads them before answering, writes to them after, sweeps them every Friday. No vector DB. No cloud. No agent memory tricks. You manage one product.

Log a decision. Drafts a complete decision file from the existing evidence trail and surfaces it for PM sign-off.
Generate solution directions for a problem, grounded in what the brain already knows. Not a brainstorm. A synthesis.
Route a new artifact into the brain. Four shapes, one verb.
Turn a new team objective into a concrete plan: what we know, what we assume, who to interview, which hypotheses to open, which experiments to run, what…
Surface what to ask, raise, or watch for in an upcoming conversation.
