provider_replace_cert_library_item_consumer_refs

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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false and openWorldHint=true. The description does add real behavioral information beyond that: this is a full-set replacement, so previously present consumer refs are dropped — a fact an agent could not derive from the annotations. It still omits permission requirements and whether removal of refs is reversible, and the 'replace' semantics sit in mild tension with destructiveHint=false without being explained.

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 first two sentences say the same thing twice; the duplication wastes roughly a third of the text and signals machine-generated boilerplate. The HTTP path at the end is useful metadata but is not front-loaded and is already surfaced in the annotation title.

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 mutation on a nested, paged-list body with no output schema, the description gives no return information, no permissions or auth context, and no explanation of the paged wrapper. An agent could invoke it, but it cannot predict the effect on refs that are omitted from the 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 coverage is 100%, so the baseline is 3: both certLibraryItemId and the body wrapper are documented in the schema. The description adds nothing about the critical ambiguity that the body is a paged-list envelope where page/pageSize/pageCount/resultTotal seem irrelevant for a PUT and only 'values' carries the actual references — clarifying that would have been the description's job.

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 verb 'replaces' and the resource (consumer refs of a certificate library item) are identifiable, and the PUT path confirms it is a full-set overwrite. However, the two opening sentences restate the same fact twice in slightly different, inconsistent terminology ('used by references' vs 'consumer references'), which muddies rather than sharpens the purpose, and nothing distinguishes it from siblings like provider_add_consumer_ref_to_cert_library_item.

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 guidance on when to use a bulk replace versus the sibling add-single-consumer-ref tool, no mention of required permissions, and no note about when a replace is inappropriate. The agent must infer selection criteria from the name alone.

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