Get Delx Wellness Profile

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

Annotations already mark it read-only, idempotent, and non-destructive. The description adds useful behavioral context: the local file path, the exact content categories returned, and a strong guarantee that it NEVER contains OAuth tokens or API secrets. No contradiction with annotations.

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?

Three short sentences, with the action and path front-loaded, the return contents summarized in one list, and a decisive safety warning. Every sentence carries useful information; no filler.

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 one-optional-parameter read tool with no output schema, the description covers what is read, where it lives, what it returns, and what it never contains. It does not address missing-file behavior or explain how response_format changes output, but the schema covers the parameter and these are minor gaps.

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, response_format, is optional and fully constrained by its enum and default in the schema, so the agent can interpret it without help. However, description-level schema coverage is 0% and the description itself says nothing about response_format, so no additional parameter meaning is contributed.

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 specifies a clear verb and resource ('Read the shared Delx Wellness profile from ~/.delx-wellness/profile.json') and lists the returned fields. It does not explicitly distinguish itself from the similarly named sibling google_health_get_profile, so it misses the strict sibling-differentiation bar for a 5.

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 implies usage: call it when you need the Delx profile contents, and the warning that it never contains OAuth tokens suggests when not to use it for secrets. However, it provides no explicit when-to-use/when-not-to-use guidance and does not mention alternatives like google_health_get_profile or google_health_profile_update.

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