configure_vault

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

With no annotations, the description carries full burden. It only states the basic action without disclosing side effects, persistence, validation behavior, or whether the tool can be called multiple times. This is insufficient for an agent to understand the tool's full impact.

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 extremely concise with no wasted words. The first sentence immediately conveys purpose, followed by a clear parameter specification. Ideal length for a simple configuration tool.

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 single-parameter configuration tool, the description covers the basic action and parameter meaning. However, it omits important context such as whether the path must exist, if validation occurs, or if this is a one-time setup. Adequate but not fully comprehensive.

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 schema has 0% description coverage, but the description adds a clear explanation for the sole parameter: 'Absolute path to your Obsidian vault'. This compensates well for the schema gap, though it lacks examples or constraints.

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 explicitly states 'Configure the Obsidian vault path,' which is a specific verb-resource combination. It clearly distinguishes from sibling tools (e.g., create_note, search_notes) which focus on note management, not configuration.

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?

No guidance is provided on when to use this tool versus alternatives or on prerequisites. While it's implied that this setup tool should be used before other vault operations, the description lacks explicit context or warnings.

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