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

Annotations already declare readOnlyHint=false, destructiveHint=false, and idempotentHint=true, so the safety profile is covered structurally. The only behavioral context the description adds is the phrase 'privacy-filtered project metadata', which is a vague hint at filtering but says nothing about versioning (expectedVersion), idempotency key reuse, or the replacement flow implied by the schema.

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 a single short sentence, which would normally be a strength, but the sentence is incoherent ('Update hosted create presentation request') and therefore wastes its brevity. Brevity without clarity is under-specification, not conciseness.

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 12-parameter mutation with a nested object, an anyOf requirement, an idempotency key, and a versioned replacement context, and there is no output schema. An eleven-word sentence that contradicts its own tool name is completely inadequate to explain how to invoke this correctly.

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 67%, below the 80% baseline, so the description should compensate but does not. 'Privacy-filtered project metadata' loosely gestures at the nested 'details' object (summary/status/referenceIds) but adds no meaning for the required topic, description, projectId, idempotencyKey, or the scopeNodeId/replacementContext alternatives defined in the anyOf.

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's verb ('Update') directly conflicts with the tool name ('create'), and 'hosted create presentation request' merely restates the name rather than describing a specific action. With four closely-named siblings (publish_presentation_request, fail_presentation_request, retry_presentation_request, get_pending_presentation_requests), the description does nothing to distinguish this tool from them.

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 when-to-use guidance, no when-not-to-use, and no mention of any alternative tool. The agent is left to guess whether this creates, updates, or replaces a request, and cannot tell it apart from the create/publish/fail/retry siblings.

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