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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and closed-world, so the safety profile is fully covered and the description does not contradict it. What it adds is that the payload is the full document text plus a public citation URL and release metadata, but that return detail largely duplicates the output schema. For a read-only tool with complete annotations, this is adequate but not rich.

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, with the usage directive front-loaded before the payload description. The middle enumeration of document types is long but each clause carries real information about what can be fetched, so there is little waste.

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?

Complexity is low (one required id, read-only, output schema present), and the description covers the workflow hook and the return contents. The one meaningful omission is routing between fetch and its three typed-getter siblings, which an agent calling this tool correctly would benefit from knowing.

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?

There is only one parameter and schema description coverage is 100%; the schema already documents the id and even gives example id forms (firm:<slug>, market:LT:trademark:national:long). The description adds nothing about id format or origin beyond the generic "after search", 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 names a specific verb (read one document in full) and resource (an IPRATE evidence document), and enumerates the three document shapes it can return, so an agent knows what it gets back. However, those three shapes map almost one-to-one onto the sibling tools get_ip_representative_profile, get_ip_market_snapshot and get_iprate_coverage, and the description never distinguishes itself from them, leaving a real ambiguity about which entry point to use.

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?

"Use this after search" gives explicit sequencing: search yields ids, fetch consumes them. That is clear when-to-use guidance. It does not state when NOT to use it versus the typed getters, so the alternative-selection rule is absent.

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