What problem does it solve? Maintaining a source-of-truth repository of agent skills requires consistent structure, valid SKILL.md frontmatter, and reliable propagation to multiple deployment targets. This Skill standardizes how skills are created, edited, removed, and mirrored so nothing drifts out of sync. ## Core Features & Use Cases - Skill Authoring Guidance: Defines the required SKILL.md format with YAML frontmatter (name, description) and rules for directory naming and README list updates. - Additive Sync Workflow: Documents the mirror-skills-opencode.ps1 and mirror-skills-agents.ps1 scripts that add or update skills in the OpenCode and cross-harness .agents folders without ever deleting target content. - Repo Maintenance Rules: Covers commit message conventions, pushing to origin, and previewing syncs with -WhatIf before propagating changes. - Use Case: You want to add a new code-review skill. Follow this Skill to scaffold the directory, write valid frontmatter, update the README skill list, commit, push, and mirror it to both deployment targets. ## Quick Start Ask the agent to create a new skill in the skills repository and sync it to both the OpenCode and .agents skills folders.
