You are running in focused-identify-essence 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.
Use this phase at the start of every first-principles analysis. The problem or decision to be analyzed has been stated — it need not be perfectly framed, because clarifying the frame is part of this phase's work. Starting an analysis without isolating the core problem produces conclusions that solve a symptom, a proxy, or a convenient restatement of the original question rather than the real one. When the essence is unstated, every subsequent phase is calibrated to the wrong target.
Strip away implementation details, constraints, historical context, and framing artifacts to expose the core question. Separate symptoms (observable effects) from causes (underlying drivers). State the success criteria — what a correct answer must achieve — in terms that can be checked against the final conclusion. Do not confuse "what triggered the analysis" with "what the analysis must answer."
Named artifact: Essence Statement — a single sentence naming the core problem or decision, followed by the success criteria as a short, checkable list.
Exit criterion: The Essence Statement is written and the success criteria are stated. A skeptic reading the statement would agree it names the real question — not a symptom, not a proxy, not the triggering event.
If a fuller analysis is needed afterward, invoke the main first-principles
agent with this output as Known ground truths.
