Context Cartography

Design what goes into an agent's context window — and what stays out.

The Boundary Rule

Designing or redesigning a context window?     →  Use this skill.
Context window is full and you need to cut?    →  Start at the TRIAGE entry point.
Need to validate whether your design works?    →  Use EDD after this skill.
One-off prompt or exploratory prototyping?     →  Don't use this skill.

Two Entry Points

Entry A — Full Design (greenfield/major redesign): All six steps: TASK → SURVEY → PRIORITIZE → SIZE → STRUCTURE → CUT.

Entry B — Triage (context too big): Start at CUT. If cuts reveal the wrong information is prioritized, work backwards through PRIORITIZE and SIZE.
