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

Annotations only declare the generic mutation profile (readOnly=false, destructive=false, idempotent=false). The description adds real side-effect detail beyond them: the task is reassigned to the Next Up queue for someone else, and the reason is posted publicly on the task. It does not clarify whether the reason becomes a comment or a field, but the key consequences are disclosed.

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 sentences, front-loaded with the action and its condition, then the consequences. No filler, nothing repeated from the schema.

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 mutation tool with annotations covering the safety profile and no output schema, the description covers the essential behavior (reassignment plus public reason). It leaves open whether the caller must be the current assignee and what the response returns, but nothing critical to correct invocation is missing.

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 50%: 'why' is documented in the schema, while 'ref' is bare. The description reinforces that the reason travels with the task ('your reason is posted on it') but adds nothing about the 'ref' format or what a valid task reference looks like. Adequate, not compensating for the coverage 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?

States a specific verb (give back/release) and a precisely scoped resource (a pre-approved task you already took and cannot finish). The reverse workflow framing implicitly distinguishes it from the pickup sibling fenbs_next_approved_task, though no sibling is named explicitly.

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 condition for use is clear: you took a pre-approved task and cannot finish it. The 'cannot finish' qualifier implies when-not to use it, but no alternative tool is named and no explicit exclusion is stated.

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