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

Annotations already establish that this is a non-read-only, non-destructive, closed-world write. The description adds useful behavioral context by saying the account is kept whole, verbatim, and permanent, but it does not explain overwrite behavior, naming conflicts, or what the response looks like.

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 a single front-loaded sentence with no obvious filler. It is efficient, though its brevity leaves gaps that other dimensions capture.

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 write tool with three required parameters, low schema coverage, and no output schema, the description is too thin. It gives the artifact concept but leaves the semantics of title and content unclear, which is a significant gap for correct invocation.

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 description coverage is only 33%, with only home_path documented in the schema. The description does not clarify the roles of title or content, so it does not compensate for the undocumented required parameters.

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 and resource: keeping a long first-person account whole and verbatim as a permanent raw-source artifact. It is clearer than the bare tool name, but it does not explicitly distinguish this from sibling save/capture tools such as save_note or capture_*.

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 a use case for long first-person accounts, but it gives no explicit when-to-use guidance, no exclusions, and no named alternatives. An agent must infer whether this should be used instead of save_note or the capture_* tools.

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