Planning and productivity prompts for Claude Fable 5
Six scaffolds for planning, prioritising and deciding, written to force a recommendation rather than a menu.
What actually helps here
Give it the constraint that hurts. A plan produced without a budget, a deadline or a headcount is a list of everything reasonable, which is not a plan. Name the binding limit and require the output to say what is being given up — a recommendation that costs nothing to make is worth about that much.
The prompts
Fill in the bracketed slots, paste into any Claude app or the API. Written for Fable 5's goal-first style — they state the outcome and the constraints rather than scripting the steps.
Meeting agenda
Draft a [30]-minute meeting agenda to decide [decision]: pre-reads, 3 timed discussion blocks, a decision protocol, and owner assignments.
Weekly priorities
Here is my task list: [paste]. Group into Now / Next / Later using impact vs urgency, flag anything delegatable, and identify the one task that unblocks others.
One-page project brief
Turn this idea into a one-page project brief: [idea]. Sections: problem, success metric, scope (in/out), risks, first milestone.
Decision matrix
Build a weighted decision matrix for choosing between [options] using criteria: [list them, or propose 5]. Show the scoring and how sensitive the result is to the weights.
Retrospective
Run a written retrospective on [project]: what worked, what didn't, what we'd change, plus one experiment for the next cycle. Keep each section to 3 bullets.
Thread triage
Summarize this thread and draft a reply: [paste]. The reply should confirm decisions, list open questions, and propose the next step in under 120 words.
Getting more out of these
Two habits matter more than the wording. Replace every bracketed slot before you send — Fable 5 follows instructions literally, and an unfilled [topic] becomes part of the task. And resist adding "think step by step" or "show your reasoning": on Fable 5 that phrasing can trip the reasoning_extraction classifier and hand your request to Opus 4.8 instead.
Need something these do not cover?
The generator builds a full system prompt around your own task, autonomy level and output style, and hands back the API call to go with it.
