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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so safety is covered. The description adds real behavioral detail beyond that: the group ordering rules (in-progress first, then urgent bugs/tasks, then bugs/tasks) and the non-obvious pool semantics for the token owner's own queue. It does not cover pagination or result caps.

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?

Front-loaded with the core return shape and grouping before the pool caveat, and every clause carries information. The includePool sentence is a long run-on that packs several conditions together, costing some readability.

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?

No output schema exists, but the description explains the grouping, ordering and pool composition, which is essentially what the agent needs to interpret results. A read-only list tool with annotations covering safety is adequately specified; only pagination/size limits are unaddressed.

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%, so a baseline of 3 applies, but the description genuinely enriches it: includePool is explained as the shared "any" pool matched to role and level, and that in the token owner's own queue it lists only tasks they can take — meaning not present in the schema text. statuses and userID are only lightly reinforced.

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 and resource (returns a person's queue in a product) plus scope (token owner's or userID's) and the grouping model. It is clearly distinguishable from siblings like task_search or worklog_list because it describes the assignee-stage grouped view and pool inclusion.

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?

Explicitly frames the trigger: "Useful when the user asks what to work on next," which tells the agent the intent-level scenario. It does not name alternatives or exclusions (e.g. vs. task_search or worklog_list), so it stops short of full routing guidance.

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