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

Annotations already declare the operation is not read-only, not idempotent, and not destructive. The description adds meaningful business behavior: delivered work must include a release and verification, and reporter acceptance is a separate fact. It does not cover permissions, side effects, or conflict behavior, but it adds useful context beyond annotations.

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 two tightly written sentences with the main action front-loaded. Every sentence carries domain meaning, and there is no filler.

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?

This is a complex mutation tool with 10 parameters, 8 required fields, and very low schema description coverage. The description omits most parameter semantics, prerequisites for creating versus updating, and how workId controls update behavior; the output schema reduces the need to explain return values, but the input-side gaps remain substantial.

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 description coverage is only 10%, with just widgetId documented, so the description must compensate for 10 parameters and 8 required fields. It only indirectly clarifies deliveredRelease and verification semantics; title, description, status, assignee, nextAction, workId, and updatedAt remain semantically unexplained.

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 uses a specific verb phrase, "Create or update," with a clear resource, "engineering work," so an agent can distinguish this save operation from sibling read/list/triage tools. It does not explicitly name sibling alternatives, but the purpose is clear.

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 provides a domain rule for delivered work requiring a release and verification, which helps guide status handling. However, it does not state when to use this tool versus support_triage_ticket, support_list_work, or support_get_ticket, nor does it explain when not to use it.

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