Scaffold a starter vault

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Despite annotations already indicating non-read-only behavior, the description adds valuable detail: it writes Markdown files into the root and subfolders, skips existing files unless overwrite:true, requires TDMCP_VAULT_PATH, and describes the return value. This is far beyond what annotations provide alone.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is efficiently structured in three sentences: purpose, behavior, and usage/prerequisites/return. Every sentence adds distinct information without redundancy, and the most important information is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one optional parameter and no output schema, the description covers the primary purpose, side effects, prerequisite, return value, and relationship to sibling tools. Complete enough for an agent to select and invoke it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the only parameter (overwrite) is fully described in the schema. The description's mention of 'skipped unless overwrite:true' repeats the same meaning without adding new semantic detail beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with a specific verb ('Populate') and resource ('configured Obsidian vault'), and explicitly differentiates it from sibling tools by noting this runs before save_recipe_to_vault/import_setlist/etc.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit usage context: 'Run this once when first setting up a vault' and names the exact ordering relative to related tools. This goes beyond implied usage and offers clear alternatives for later steps.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
