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

With no annotations, the description carries the full burden; it usefully discloses that output contains answers plus worked solutions and is explicitly UNREVIEWED, which signals downstream caution. It does not say whether the draft is persisted, whether generation consumes quota or is rate-limited, or whether any prerequisite state (existing skill, grade band validity) is required.

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 tight sentences with the core action and scope front-loaded, and the parenthetical efficiently packs item count and output contents. No filler, though the all-caps 'UNREVIEWED' is slightly emphatic rather than explanatory.

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 simple three-parameter generator with no output schema, the description covers what is produced but not what happens to it or how it enters the review workflow. An agent knows how to call it but not the full lifecycle of the result.

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 0%, so the description must explain all three parameters. It adds a real constraint (1-10 items) for count and implies skill_id scope via 'one skill', but grade_band is never mentioned at all and the default count of 6 is absent, leaving one parameter entirely opaque.

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 ('Draft') and resource ('a practice set') and bounds the scope to one skill and 1-10 items. The sibling tools are all listing/lookup/registration operations, so the generation role is easy to separate, but the description never names or contrasts a sibling 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?

Usage is implied by 'for one skill' and the draft framing, but there is no explicit when-to-use or when-not statement, and no guidance on what an agent should do next with the unreviewed output (e.g., route it to a review step) despite submit_claim existing as a sibling.

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