nina_sequence_set_target

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

With no annotations, the description carries the burden. It indicates that the operation is an update (mutation) but lacks details on side effects, failure modes (e.g., invalid index), or what happens to existing values. It is minimally transparent but not comprehensive.

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 adequately sized but could be more concise. The purpose is clear, but the parameter list is repetitive (e.g., 'target container' repeated). Front-loading of the purpose is good, but the structure is a plain paragraph.

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 no annotations and no output schema, the description is not sufficiently complete. It does not mention return values, error conditions, or state changes. It assumes domain knowledge (DSO target container) and lacks context for successful invocation.

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?

The description explicitly explains each parameter with units (hours for ra, degrees for dec and rotation, 0-based index). This compensates for 0% schema description coverage. However, it could be improved by adding valid ranges or constraints.

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 verb 'update' and the resource 'DSO target container already present in the loaded sequence', specifying the attributes (coordinates/name/rotation). It distinguishes from sibling sequence tools by focusing on modifying an existing target container within a loaded sequence.

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?

No explicit guidance on when to use this tool versus siblings like nina_sequence_edit. No prerequisites are mentioned (e.g., must have a sequence loaded). The description does not provide when-not-to-use instructions or alternative tools.

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