A serious BUG: Subagents do not execute Skills, including their own!

[Perlover]

Background

In the original Agent OS, subagents have a limited set of tools defined in their frontmatter (e.g., tools: Write, Read, Bash, WebFetch, Playwright). Based on analysis of Claude Code behavior, subagents only receive skill headers when the Skill tool is explicitly listed in their tools. Without it, subagents cannot access any skills.

A patched version of Agent OS adds Skill to the tools list of relevant subagents, allowing them to:

• Receive skill headers describing available skills
• Decide whether to load and use specific skills based on context
• Access user's custom skills

UPDATE:

As proof that the original version of Agent-OS does not work with Skills while the patched version does, I created a test repository, verified it myself, and confirmed that this is exactly the case. Here is the link to the repository.
