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

The annotations already declare destructiveHint=true, openWorldHint=false, and idempotentHint=true, so the description's restatement of closed-world and destructive scoping adds limited new information. However, it does add genuinely new behavioral detail: only supplied fields are overwritten (implying a partial rather than full-replace update) and previous values are not automatically preserved or restored. It still doesn't describe error behavior for a bad id or permission requirements.

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 sentences, front-loaded with the action and resource, with no filler. The second sentence is a little heavy on restating annotation-declared properties (closed-world, destructive), but it stays compact and earns its place through the non-preservation detail.

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?

An output schema exists and parameter coverage is complete, so the description doesn't need to explain returns or argument shapes. For a mutation tool it covers the essential safety story (partial overwrite, no automatic restore, scoped to the authenticated account). The remaining gap is the accepted contents of the data object and the prerequisite of having a valid hosting id.

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%, so every parameter is already documented in the schema, and the baseline is 3. The description adds only the framing that 'data' contains the fields to be overwritten; it does not enumerate which hosting fields are accepted inside the nested, open-ended data object, which is the one place the schema leaves ambiguity.

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 verb and resource ('Update a Tripsy hosting') plus the keying mechanism ('by id'), which separates it from the create/delete/list/show siblings in the tripsy_hostings family. It stops short of naming an alternative tool or clarifying the relationship to tripsy_hostings_show for retrieving current values before overwriting.

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?

There is no explicit when-to-use or when-not-to-use guidance beyond the implied 'you have an id and want to change it'. It never says an id must first be obtained from tripsy_hostings_list or tripsy_hostings_show, nor when to prefer create over update. Usage is inferable from the verb and the name only.

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