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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered without the description. The description adds that results are scoped to the signed-in user and that entries carry Bristol type 1-7 plus flags, which is modest but real added context.

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?

A single front-loaded sentence with no filler. Nothing extraneous and the scope qualifier comes before the payload detail.

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 and no parameters, annotations carry most of the behavioral burden, but the description omits ordering, time range, and whether entries are paginated or limited. Adequate to call correctly, but incomplete for an agent needing to reason about the result set.

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?

Zero parameters, so per the baseline this scores 4. The description's parenthetical about type and flags is output-shape information rather than parameter guidance.

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 (List) and resource (Bristol stool entries) scoped to the signed-in user, and hints at the payload shape ('type 1-7 plus flags'). The add/list distinction from vora_add_bristol is inferable from names, but the description never explicitly differentiates itself from siblings.

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 statement of when to use this versus alternatives; the only implicit cue is the verb 'List'. A user wanting to record an entry must infer on their own that vora_add_bristol is the counterpart write tool.

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