Switching to Fable 5.1? Run a Prompt Audit First — Old Emphasis Triggers Wasted Tool Calls
RLanceMartin · x · 2026-09-03
A practical workflow for moving from Claude Code to Fable 5.1: run /claude-api prompt-audit across your Skills workspace. It surfaced duplicate constraints, dead slash commands, hard-coded old model names, and output scaffolding written for older models.
Key insight: Fable 5.1 follows instructions more literally, so old emphasis like "CRITICAL: You MUST use this tool when..." now triggers repeated checks and unnecessary tool calls — simplify to "Use this tool when...". The command only produces an audit report and proposed diff with location, explanation and confidence; you decide what to apply.
