Get the free Fable 5 Driver's Manual (the 7 moves + copy-paste prompts)

Claude Fable 5 is Anthropic's most capable model — 1M context, thinking always on, and single requests that run for minutes as it plans, delegates and checks its own work. That's also why the old chatbot habit (type one line, hit enter) wastes almost everything it can do. This manual is the fix: 7 moves to drive Fable 5 at full power, each with the exact instruction to paste in. (1) GIVE IT THE WHOLE TASK at high effort — one complete brief beats ten vague follow-ups. (2) TELL IT TO ACT — a one-line instruction that stops it over-planning. (3) BAN THE TIDYING — stop it refactoring and gold-plating things you didn't ask for. (4) GIVE IT A MEMORY — a plain text file it reads and updates so it never repeats a mistake. (5) LET IT RUN A TEAM — delegate to async sub-agents instead of doing everything itself. (6) MAKE IT PROVE EVERY CLAIM — ground its progress reports in real results, and set a boundary so it doesn't take actions you didn't ask for. (7) MATCH THE EFFORT TO THE JOB — Fable 5 at LOW effort still beats older models at their max, so you get frontier output without lighting money on fire ($10/$50 per million tokens). Includes a MASTER BLOCK that combines the key instructions into one paste for your system prompt or CLAUDE.md, plus two gotchas: it needs 30-day data retention, and its safety classifier can occasionally decline benign work (set an Opus 4.8 fallback in the API).
