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

The description adds context about the update method (JSON Patch) and scope (specific fields), which goes beyond the openWorldHint annotation. However, it doesn't disclose critical behavioral traits like authentication requirements, rate limits, or mutation effects. With annotations covering only open-world aspects, the description provides moderate but incomplete behavioral insight.

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 description is a single, efficient sentence that front-loads the core purpose ('Update specific fields') and method ('JSON Patch operations'). There is no wasted text, and it directly communicates the tool's function without redundancy.

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?

Given the tool's complexity (mutation with 4 required parameters) and lack of output schema, the description is adequate but incomplete. It covers the what and how but misses details like response format, error handling, or prerequisites. With annotations only providing openWorldHint, more context would improve completeness for this non-trivial tool.

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?

With 100% schema description coverage, the schema fully documents all 4 parameters. The description adds no additional parameter semantics beyond implying JSON Patch usage, which aligns with the schema's operations field. This meets the baseline of 3 for high schema coverage without extra value.

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 clearly states the specific action ('Update specific fields'), resource ('managed object in PingOne AIC'), and method ('using JSON Patch operations'). It distinguishes from siblings like createManagedObject (full creation) and updateTheme (different resource type), making the purpose unambiguous.

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?

The description implies usage for partial updates via JSON Patch, suggesting when to use it (field-specific modifications) versus alternatives like createManagedObject for new objects. However, it doesn't explicitly state when NOT to use it or name specific alternatives, keeping it at a 4.

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