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

Annotations already declare readOnlyHint, idempotentHint, closed-world and non-destructive, so safety is covered. The description adds real value beyond them: a staff-only access restriction, and a preview of what each row carries (status, judge score, problem, draft template, plus a count per status).

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?

Compact, but it is a single run-on sentence with a sentence fragment ('Fetch Hive staff only.') bolted to the front, and the return-field list is crammed into a parenthetical. Nothing is wasted, but the structure makes the key access constraint easy to misread.

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?

With no output schema, the description usefully previews the returned fields and the per-status counts, and it flags the staff-only restriction. For a four-parameter, zero-required list tool this is close to sufficient; only the category parameter and pagination/limit behavior remain 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 75%, so the schema does most of the work for limit and kind. The description does add meaning by enumerating all eight valid status values, which the schema only hints at with two examples, but it says nothing about category, leaving one parameter undocumented in both places.

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 (fetch/list) and resource (the template library's ideas), and clarifies the default scope is workflow templates with kind: agent or all. That distinguishes it from sibling mutators like library_add_idea or library_update_idea, though the opening fragment 'Fetch Hive staff only' is awkwardly spliced on and blurs the read.

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?

There is no explicit when-to-use statement and no named alternative (e.g. get_template or library_todo) to route the agent. The kind default is parameter guidance rather than usage guidance, so the agent must infer that this is the enumeration tool.

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