iaas_update_project_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, so the safety profile is carried structurally. The description adds nothing beyond the endpoint path — notably it does not say whether PATCH-ing tags replaces or merges the existing metadata, which is the single most consequential behavioral question for the caller.

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 and the endpoint path is front-loaded, but the first two lines are the same sentence written twice, which is wasted space given how little information is actually conveyed.

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?

This is a mutating PATCH with a nested body object, no output schema, and no description of the response or of merge semantics. For a mutation tool with nested parameters, the description leaves a caller unable to predict the effect on existing tags or the returned payload.

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%, and the schema documents id, body.tags (key/value) and apiVersion thoroughly, so the baseline of 3 applies. The description adds no parameter-level meaning, such as whether omitting tags clears them or whether apiVersion is optional in practice.

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 restates the tool name almost verbatim ("Update project resource metadata ... by a given project id") and adds only the HTTP path. It conveys the verb and resource, but never explains what 'resource metadata' actually is (the tag set shown in the schema), and it does not distinguish itself from near-identical siblings such as project_patch_projects_by_id_resource_metadata or iaas_get_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?

There is no indication of when to use this tool, what preconditions exist (project must exist, project id required), or which sibling to prefer. In a catalog containing both iaas_update_project_resource_metadata and project_patch_projects_by_id_resource_metadata, the absence of routing guidance is a real gap.

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