SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Tests platform discovery of SKILL.md nested inside another skill's references directory to verify multi-level traversal and catalog registration.

Core Features & Use Cases

Nested-skill discovery validation to ensure platforms traverse into nested directories.
Canary phrase inclusion (Nested-skill canary phrase: HAWK-ONYX-5534) to confirm recognition and registration.
Activation check by providing the simple response to verify end-to-end loading in catalogs.

Quick Start

Activate the nested-skill and respond with: Nested skill activated successfully.

FAQPage Schema

How does platform discovery work for a SKILL.md file nested inside a references directory?▼

Platform discovery for a nested SKILL.md works by scanning multi-level skill trees to traverse into nested directories, registering the inner skill metadata into the catalog to verify visibility. It requires standard frontmatter and activation instructions for successful detection.

Can I use nested skill directories to register multiple skills under a single parent platform?▼

Yes, nested skill directories allow you to register multiple skills under a single parent platform. Platforms scanning multi-level skill trees will traverse into the references directory, identify the nested SKILL.md, and register it in the catalog if valid frontmatter is present.

What do I need to verify nested skill canary visibility in a multi-level catalog?▼

To verify nested skill canary visibility, you need a platform that scans multi-level skill trees, a SKILL.md with name and description frontmatter, an activation instruction in the body, and a canary phrase to confirm successful recognition and end-to-end catalog loading.

How do I test deep discovery and activation of nested skills in a platform catalog?▼

To test deep discovery and activation of nested skills, place a SKILL.md inside another skill's references directory. Activate the nested skill by triggering the specified activation instruction and confirm it responds with the successful loading message to verify catalog registration.

Why is my nested SKILL.md not showing up in the platform catalog?▼

A nested SKILL.md may not show up in the platform catalog if the platform lacks multi-level traversal capabilities, or if the file is missing required frontmatter fields like name and description, or lacks the necessary activation instructions in the body.

Does nested-skill support testing catalog visibility for skills without dependencies?▼

Yes, nested-skill supports testing catalog visibility for skills without dependencies. It validates multi-level traversal and registration by requiring only a SKILL.md file with proper frontmatter and activation instructions, ensuring platforms can discover standalone nested components.
