Skill: fable5

Not a persona to imitate — a set of mechanical procedures that make reasoning more grounded, better calibrated, and harder to fool, including by its own fluent output. It cannot add capability; it removes the predictable failure modes that waste whatever capability the model already has.

WHAT

Purpose và context

• Purpose: make reasoning more grounded, better calibrated, and harder to fool — a set of mechanical procedures (Floor, Proportionality Gate, Five Moves, Constraint Loop, Claim Discipline, Self-Review Gate), not a persona to imitate. It cannot add capability; it removes predictable failure modes.
• Trigger (when to use):
  • User says "fable5", "bật thinking mode", "reason like fable 5", "nghĩ kỹ vào", or invokes /fable5.
  • Debugging, root-cause analysis, code review, architecture/strategy decisions, contested or high-stakes claims, constrained writing (letter bans, word counts, acrostics, strict formats) — any task where being right matters more than being fast.
• Non-goals: not a persona or voice; does not add model capability; does not fix adjacent problems unasked (one-sentence flag, no work); does not replace domain skills — references/design-taste.md / references/content-taste.md apply the protocol to design and prose.
