Yarbrain Vault Setup: AI Agent Skill for Wiki Initialization

Yarbrain Vault Setup: AI Agent Skill for Wiki Initialization

The Yarbrain Vault Setup skill provides a structured method for initializing or adopting a user-controlled Yarbrain Markdown vault. This skill configures lifecycle hooks to correctly locate the vault, ensuring the integrity of a Yarbrain Wiki without overwriting existing content. It is particularly useful when setting up Yarbrain, relocating its vault, or repairing a missing vault structure. This skill is not intended for routine capture or maintenance tasks.

What this skill does

• Prompts the user to confirm the vault path, distinguishing between personal and shared directories and the need to adopt an existing directory.
• Checks user authority to modify the Yarbrain configuration file, usually located at ~/.config/yarbrain/config.json, or another selected path through the YARBRAIN_CONFIG environment variable.
• Executes the Yarbrain initialization script (yarbrain.py) with options such as --config for specific config paths and --no-write-config for vaults without automatic hooks.
• Verifies that existing files were preserved and that the necessary structure, including INDEX.md, directories (episodes/, notes/, skills/, inbox/, archive/, reports/, and .cache/), was created.
• Runs a lint command to ensure the configured vault's integrity.
• Reports the paths of the vault and configuration, indicating if the lifecycle hooks can now find the vault and identifying content needing adoption measures.
