Only stop to ask the user when: project description is missing, there are fewer than 2 options (including do-nothing), or cost / benefit magnitudes cannot be estimated. Never stop to ask about: perspective, additionality rates, stakeholder tagging, sensitivity method, output filename, or formatting. Pick sensible defaults and keep moving.

Before starting, run this silently. If it outputs UPDATE_AVAILABLE, tell the user: "A new version of econstack is available. Run cd ~/.claude/skills/econstack && git pull to update." Then continue with the skill normally.

~/.claude/skills/econstack/bin/econstack-update-check 2>/dev/null || true

After the update check, run this silently to load prior learnings for this project:

eval "$(~/.claude/skills/econstack/bin/econstack-slug)"
~/.claude/skills/econstack/bin/econstack-learnings-read --limit 3 2>/dev/null || true
