From cce6cfb119d4960edc50d019b61208908d4a9a3d Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Thu, 30 Apr 2026 07:13:49 +0000 Subject: [PATCH 1/4] fix(skill): handle skill: wrapper key in agents skill add YAML config Implement skill: wrapper key unwrapping in SkillConfigSchema.from_yaml() to support the spec-required YAML format with cleveragents: metadata header. - Strip cleveragents: metadata block from raw YAML before validation - Unwrap skill: wrapper key if present, with descriptive errors for invalid values - Maintain backward compatibility with flat YAML format (no wrapper) -
