Subagent Optimizer · ionden bundle Use when asked to audit, optimise, slim down, or fix Claude Code subagent definitions (.claude/agents/*.md) — set a proper `tools` allowlist (an agent with no `tools` field inherits every tool on each launch), cut bloated or duplicated system prompts, tighten descriptions so they trigger reliably, and right-size the model. Triggers: "optimize my subagents", "optimise my agents", "audit my subagents", "subagent optimizer", "my agent uses too many tokens", "fix the tools list", "review .claude/agents", "make my agents cheaper".
