get_now_assist_skill

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

Annotations already provide readOnlyHint and openWorldHint. The description adds the prerequisite NOW_ASSIST_ENABLED, which is useful beyond annotations. It does not detail error behavior or return structure, but the annotations cover the safety profile.

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 sentence, front-loaded with the action, and includes a relevant prerequisite in parentheses. No unnecessary words; efficient and clear.

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 simple get-by-ID tool with one parameter and annotations, the description covers purpose and a prerequisite. It lacks details about the return structure or where to find sys_id, but is mostly complete given the tool's simplicity.

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% with sys_id described as 'System ID of the skill'. The description adds 'by sys_id' but no additional semantic meaning. Baseline 3 is appropriate as the schema does the heavy lifting.

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 'Get a single Now Assist skill definition by sys_id', specifying the verb and resource uniquely. It distinguishes from sibling tools like list_now_assist_skills (listing) and create_now_assist_skill (creation).

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 use when you have a sys_id and need a skill definition, and mentions the prerequisite 'requires NOW_ASSIST_ENABLED'. However, it lacks explicit guidance on when not to use it (e.g., for listing) or alternatives, though context from siblings helps.

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