Individual skill

hindsight

Reviews everything accomplished in the current session end-to-end, distills genuine process lessons (not one-off content specifics), and saves the durable ones as persistent memory — updating an existing related memory in place rather than duplicating it. Trigger on "get some hindsight," "run a hindsight pass," "what should we improve," "review today and notate lessons," "what did you learn today," "save what's worth remembering from this session." Does not redo or re-open any of the session's actual work, and never fabricates a lesson just to have something to report.

# Hindsight

A session-end self-improvement pass. Read-only against the session's actual
work — it never redoes or re-opens a task — and write-only against memory.
User-triggered only: a hindsight pass writes persistent memory, so timing
stays the user's call, never something run on a hunch.

## When this fires

On-demand only: "get some hindsight," "run a hindsight pass," "what should
we improve," "review today and notate lessons," "what did you learn today,"
"save what's worth remembering from this session."

## Process
