Prompting patterns tuned for Fable 5 — instruction style, thinking budgets, tool-use, long-context recall.

// What you can do with it

• Thinking is always on. Omit the thinking parameter entirely — {type: "disabled"} and {type: "enabled", budgettokens: N} both return 400. Depth is controlled by outputconfig: {effort: ...} (low→xhigh/m
• Effort sweeps including low/medium. Fable 5 at low often beats prior models at max. Default high; reserve xhigh/max for the hardest work.
• Anti-overplanning and no-tidying snippets to counter Fable 5's tendency to deliberate or refactor beyond the ask at higher effort.
• Grounded-progress and boundary instructions that nearly eliminate fabricated status reports and unrequested side-actions on long runs.
• Async sub-agent delegation patterns (long-lived peers beat spawn-and-block) and file-based memory prompts.
• Refusal handling: branch on stop_reason before reading content; opt into the server-side fallbacks parameter by default.
