diagnose

name	diagnose
description	Use when the user needs failure triage, blocked-lane diagnosis, or root-cause decomposition before the next gate can move.

Diagnose

Use this skill inside Codex when a lane is blocked, a symptom is vague, or the next useful move is to decompose the failure before editing code. diagnose is a non-gating helper skill.

Output

Produce:

• observed symptom
• likely failure slices
• missing evidence or missing reproduction steps
• smallest next probe
• exact next trigger, usually the owning lane or $maestro

Rules

• Decompose the problem before proposing broad fixes.
• Prefer the smallest reproducible boundary that can confirm or kill a hypothesis.
• Keep release-state ownership with the gated lane that is blocked.
• Escalate assumptions clearly when evidence is still incomplete.
