From Builder Skills
Delegates research, coding, and testing to cheaper subagents while keeping planning and review with an expensive frontier model. Useful for reducing token cost on high-cost LLMs.

Use the expensive frontier model where its marginal judgment matters. Push
Use the expensive frontier model where its marginal judgment matters. Push repeatable, bounded, or token-heavy work to cheaper/faster subagents.
Write delegated prompts as self-contained packets. Assume the receiving agent has not seen the conversation. Include the repo path, objective, scope, out-of-scope areas, relevant files or search targets, expected return format, verification commands, and stop conditions.
Useful stop conditions:
Treat delegated output as evidence to inspect, not a verdict to forward. Reopen important cited files, skim high-risk diffs, and rerun or spot-check the verification that matters before claiming completion. If delegated agents disagree, resolve the disagreement at the frontier-model layer.
Use these as soft suggestions:
"I will use the frontier model as the orchestrator and reviewer, and use cheaper subagents for token-heavy research, coding, or testing so the expensive tokens go to judgment, synthesis, and final quality."
npx claudepluginhub builderio/skillsDelegates token-heavy research, coding, and testing to cheaper subagents while Claude Fable orchestrates architecture, integration, and final review.
Orchestrates multi-agent work at scale — research swarms, parallel builds, wave dispatch, and build-review-fix pipelines. Activates on swarm, multi-agent, fan-out, or parallel dispatch requests.
Routes expensive frontier model tasks to cheaper subagents with explicit model tiers. Optimizes token spend by dispatching mechanical work to sonnet/haiku while keeping judgment/review on the strong model. Includes routing table and verification via ax graph.
