ispw_create_assignment

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

Annotations already disclose that this is a non-readonly, non-idempotent, non-destructive, closed-world operation. The description adds useful context by stating the uniqueness constraint on assignment_id and that the tool returns created details or an error message, but it does not cover permissions, duplicate-handling specifics, or broader side effects.

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 well structured with Args, Returns, and Examples sections, and the key purpose is front-loaded. It contains some redundancy between the first two sentences, but overall it is appropriately sized for a create tool.

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 that annotations cover the safety profile and an output schema exists, the description provides sufficient information about required inputs and the uniqueness constraint. It could be more complete around failure modes or permissions, but nothing critical is missing for basic 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?

Although the top-level schema description coverage is low, the description enumerates all nested input fields, including optional fields and the default response format, and provides a concrete example. It largely mirrors the nested schema descriptions rather than adding deep semantics, but it does compensate for the top-level gap.

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 states a specific verb and resource: creating a new ISPW assignment container for grouping related development work. It is clear what the tool does, though it does not explicitly distinguish the tool from siblings such as ispw_generate_assignment or ispw_create_release.

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?

Usage is implied by describing the assignment as a container for related development work and by noting that the assignment ID must be unique within the SRID. However, there is no explicit guidance on when to use this tool versus alternatives, nor any when-not-use conditions.

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