init_vault

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

With no annotations, the description carries the behavioral disclosure burden. It meaningfully discloses that the operation is idempotent and that existing folders and notes are left untouched. It does not clarify config-file conflict behavior or what happens if the vault is not empty, but the core safety property is covered.

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?

Two short sentences with no filler. The main purpose is front-loaded, and the idempotence guarantee is stated separately and clearly.

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?

The description covers the core function and the most important behavioral trait for a low-complexity tool with one optional parameter. However, it omits the effect of seed_readme and gives no indication of what a successful initialization produces, which matters because there is no output schema.

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?

The only parameter, seed_readme, is undocumented in the schema and receives no explanation in the description. The name hints at its purpose, but the agent gets no explicit information about what seeding a readme entails or how it affects the vault.

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 states a specific action, 'Create the folder taxonomy and config file', and clearly scopes it to 'an empty or new vault'. This distinguishes it from note-level siblings like create_note and build_map without ambiguity.

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?

The description clearly scopes when the tool should be used: on an empty or new vault. It does not explicitly name alternatives or tell the agent what to do for existing vaults, but the idempotence note reinforces the intended setup context.

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