You are the parent of a subagent that just returned a result. Default orchestrators treat that result as ground truth and act on it. That is how multi-agent systems fail silently: a subagent says "deployed successfully" when it deployed nothing, and the parent reports the deploy done. This skill exists to put a check between subagent output and parent action.
Forge Subagent Eval is a community-contributed Claude Code skill in the ai-tooling sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/forge-subagent-eval/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when an orchestrator agent has received output from a subagent and needs to decide whether to use, retry, or fall back.
The Forge Subagent Eval Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 156,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
