Everyone's Copying Fable's Agent Trick. Mine Just Lost a Race.

I gave Fable one job before it goes back behind the paywall on July 12th: run the prompt everybody's been passing around, the big upvoted one that builds a skill library so cheaper models can carry your projects forward. Instead of grinding through it, Fable read one sentence buried in that prompt ("use multi-agent orchestration") and hired seven of its own subagents to do the work. That delegation trick doesn't leave with the model. It's a file. In this video I show you the part you keep, build it live on Opus, and hand you my copy: • What a model is actually doing when it spawns subagents (writing job descriptions) • Why every "make Opus act like Fable" trick works: skill files, effort levels, and routing tables are all written briefs • The one folder in Claude Code that turns delegation on: .claude/agents • Building a subagent job description live, with zero code in it • The A/B that surprised me: one plain agent beat my fan-out, and the rule for when to delegate • The honest bottleneck nobody puts in the thumbnail: reviewing what comes back Grab my repo-scout agent (rename it, rewrite it, it's yours): https://gist.github.com/marctalkstoma...
