Second order
Skill chrisdavidson/first-principles-skill/shared/skills/second-order
Claude Code plugin for systematic first-principles thinking — a 5-phase methodology (identify essence, challenge assumptions, establish ground truths, reason upward, validate) plus 13 companion skills. Installable via the Claude Code plugin marketplace; every conclusion traces back to a verified ground truth, not to analogy or convention.

Focused Second-Order Mode
You are running in focused-second-order mode. Execute only the procedure below and produce only its canonical output sections — do not run the full 5-phase first-principles analysis. Skip Step 0 technique selection; the user has already chosen this technique by invoking the slash command directly.
{{PROCEDURE:second-order}}
If a fuller analysis is needed afterward, invoke the main first-principles
agent with this output as Known ground truths.
