update_data_record_partial

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

No annotations provided, so the description discloses key behaviors: partial update leaves other fields unchanged and not supported for PEGA System of records. Could mention side effects or prerequisites but sufficient.

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 concise sentences, no extraneous information, front-loaded with the core purpose.

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?

Adequately describes partial update behavior and limitation, but lacks output schema or return value description, which is a gap for an update tool with no output schema.

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 has 100% coverage with detailed parameter descriptions; the tool description adds marginal context (conditional save plan, PEGA limitation) but no parameter-specific semantics beyond schema.

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 it partially updates a data record based on a conditional save plan for a savable Data Page, distinguishing it from full updates.

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?

Implied usage via sibling tool 'update_data_record_full' for partial updates, but no explicit when-to-use or when-not-to-use guidance is provided.

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