project_patch_projects_by_id_resource_metadata

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=true; the description adds nothing behavioral beyond restating the HTTP verb and path. It does not explain whether the tags list replaces or is merged into existing metadata, which is the critical unknown for a non-idempotent PATCH.

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?

It is short, but the first line 'Modifies a project resource metadata' is redundant with the second sentence, and the trailing URL duplicates what is already in the annotations title. Structurally front-loaded but with avoidable repetition.

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?

With a 100%-covered nested schema and no output schema, the description covers the basic identity of the operation. However, for a mutation tool with idempotentHint=false, it omits what a successful response looks like and whether existing metadata is overwritten, leaving meaningful 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?

Schema description coverage is 100%, so the id, body.tags and apiVersion parameters are already fully documented in the schema. The description adds no format, merge semantics, or example detail beyond that, so the baseline 3 applies.

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+resource: it modifies the resource metadata of a project identified by id, and includes the endpoint. It is clear what the tool does, but it does not distinguish itself from close siblings such as project_get_projects_by_id_resource_metadata or iaas_update_project_resource_metadata.

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?

Usage is only implied by the 'PATCH .../{id}/resource-metadata' phrasing. There is no explicit statement of when to use this versus the GET counterpart or the iaas_update_project_resource_metadata tool, and no prerequisites or exclusions are given.

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